im trying to make a average grade calculator, now thats is going fine but now i want to calculate the average immediately when a number gets inputted in one of the fields. I've been trying this with "on(), live(), onkeyup()" but can't get it to work.
The result of the average now displays beneath the inputfields 'onclick' on the button. I want the average displayed there but then as soon as you input numbers in one of the fields it should show there as it now does after the onclick.
What i've tryed with the 'on(), live(), onkeyup()' is to connect them to the input fields and connect them to the calculator() function.
Is there a easy way to do this or a other certain way?
greetings.
function calculator() {
var weight = 0;
var mark = 0;
var weights = document.querySelectorAll('[id^=weight-]');
var grades = document.querySelectorAll('[id^=mark-]');
var trs = document.getElementsByTagName('tr');
var tBody = document.getElementsByTagName('tbody')[0];
var totalWeight = 0;
var totalGrade = 0;
for (var i = 0; i < weights.length; i++) {
totalWeight += +weights[i].value;
}
for (var i = 0; i < grades.length; i++) {
totalGrade += +grades[i].value;
}
var finalGrade=totalGrade/totalWeight;
var display = document.getElementById('output-div');
var newTr = document.createElement('TR');
newTr.innerHTML = `<td><input id="weight-${trs.length + 1}" type="text" size=2 value=""></td><td><input id="mark-${trs.length + 1}" type="text" size=2 value=""></td>`;
tBody.appendChild(newTr);
display.innerHTML='Je gemiddelde is: ' +finalGrade.toFixed(2);

Using vanilla JavaScript I would attach an eventListener to the inputfields like this
document.getElementById('weight-1').addEventListener('change',function(){
calculator();
});
document.getElementById('mark-1').addEventListener('change',function(){
calculator();
});
These addEventListener functions adds listeners to the "input" field's predefined 'change'-events, and fires the calculator(); function from your code.
Seeing that you are using some sort of dynamic generation of the inputfields, you could add the listeners to your inputfields using the same querySelector that you use to target them during calculation. It would mean replacing getElementById('weight-1') in my example above with querySelectorAll('[id^=weight-]') for the weight-fields.
Also, doing work with values, IO, and calculation between html and JavaScript, I would suggest using a library like jQuery. jQuery simplifies these processes a lot.
This is the documentation for the jQuery alternative onClick function:
https://api.jquery.com/change/
I think you could do that with an angularJS module. Take a look at this tutorial : https://www.w3schools.com/angular/angular_modules.asp
maybe it will help.

Is it possible to make a HTML5 slider with two input values, for example to select a price range? If so, how can it be done?
I've been looking for a lightweight, dependency free dual slider for some time (it seemed crazy to import jQuery just for this) and there don't seem to be many out there. I ended up modifying #Wildhoney's code a bit and really like it.
function getVals(){
// Get slider values
var parent = this.parentNode;
var slides = parent.getElementsByTagName("input");
var slide1 = parseFloat( slides[0].value );
var slide2 = parseFloat( slides[1].value );
// Neither slider will clip the other, so make sure we determine which is larger
if( slide1 > slide2 ){ var tmp = slide2; slide2 = slide1; slide1 = tmp; }
var displayElement = parent.getElementsByClassName("rangeValues")[0];
displayElement.innerHTML = slide1 + " - " + slide2;
}
window.onload = function(){
// Initialize Sliders
var sliderSections = document.getElementsByClassName("range-slider");
for( var x = 0; x < sliderSections.length; x++ ){
var sliders = sliderSections[x].getElementsByTagName("input");
for( var y = 0; y < sliders.length; y++ ){
if( sliders[y].type ==="range" ){
sliders[y].oninput = getVals;
// Manually trigger event first time to display values
sliders[y].oninput();
}
}
}

No, the HTML5 range input only accepts one input. I would recommend you to use something like the jQuery UI range slider for that task.
Coming late, but noUiSlider avoids having a jQuery-ui dependency, which the accepted answer does not. Its only "caveat" is IE support is for IE9 and newer, if legacy IE is a deal breaker for you.
It's also free, open source and can be used in commercial projects without restrictions.
Installation: Download noUiSlider, extract the CSS and JS file somewhere in your site file system, and then link to the CSS from head and to JS from body:
<!-- In <head> -->
<link href="nouislider.min.css" rel="stylesheet">
<!-- In <body> -->
<script src="nouislider.min.js"></script>
Example usage: Creates a slider which goes from 0 to 100, and starts set to 20-80.
HTML:
<div id="slider">
</div>
JS:
var slider = document.getElementById('slider');
noUiSlider.create(slider, {
start: [20, 80],
connect: true,
range: {
'min': 0,
'max': 100
}
});
Sure you can simply use two sliders overlaying each other and add a bit of javascript (actually not more than 5 lines) that the selectors are not exceeding the min/max values (like in #Garys) solution.
Attached you'll find a short snippet adapted from a current project including some CSS3 styling to show what you can do (webkit only). I also added some labels to display the selected values.
It uses JQuery but a vanillajs version is no magic though.
#Update: The code below was just a proof of concept. Due to many requests I've added a possible solution for Mozilla Firefox (without changing the original code). You may want to refractor the code below before using it.
(function() {
function addSeparator(nStr) {
nStr += '';
var x = nStr.split('.');
var x1 = x[0];
var x2 = x.length > 1 ? '.' + x[1] : '';
var rgx = /(\d+)(\d{3})/;
while (rgx.test(x1)) {
x1 = x1.replace(rgx, '$1' + '.' + '$2');
}
return x1 + x2;
}

Actually I used my script in html directly. But in javascript when you add oninput event listener for this event it gives the data automatically.You just need to assign the value as per your requirement.

The question was: "Is it possible to make a HTML5 slider with two input values, for example to select a price range? If so, how can it be done?"
In 2020 it is possible to create a fully accessible, native, non-jquery HTML5 slider with two thumbs for price ranges. If found this posted after I already created this solution and I thought that it would be nice to share my implementation here.
This implementation has been tested on mobile Chrome and Firefox (Android) and Chrome and Firefox (Linux). I am not sure about other platforms, but it should be quite good. I would love to get your feedback and improve this solution.
This solution allows multiple instances on one page and it consists of just two inputs (each) with descriptive labels for screen readers. You can set the thumb size in the amount of grid labels. Also, you can use touch, keyboard and mouse to interact with the slider. The value is updated during adjustment, due to the 'on input' event listener.
My first approach was to overlay the sliders and clip them. However, that resulted in complex code with a lot of browser dependencies. Then I recreated the solution with two sliders that were 'inline'. This is the solution you will find below.
var thumbsize = 14;
function draw(slider,splitvalue) {
/* set function vars */
var min = slider.querySelector('.min');
var max = slider.querySelector('.max');
var lower = slider.querySelector('.lower');
var upper = slider.querySelector('.upper');
var legend = slider.querySelector('.legend');
var thumbsize = parseInt(slider.getAttribute('data-thumbsize'));
var rangewidth = parseInt(slider.getAttribute('data-rangewidth'));
var rangemin = parseInt(slider.getAttribute('data-rangemin'));
var rangemax = parseInt(slider.getAttribute('data-rangemax'));
/* set min and max attributes */
min.setAttribute('max',splitvalue);
max.setAttribute('min',splitvalue);
/* set css */
min.style.width = parseInt(thumbsize + ((splitvalue - rangemin)/(rangemax - rangemin))*(rangewidth - (2*thumbsize)))+'px';
max.style.width = parseInt(thumbsize + ((rangemax - splitvalue)/(rangemax - rangemin))*(rangewidth - (2*thumbsize)))+'px';
min.style.left = '0px';
max.style.left = parseInt(min.style.width)+'px';
min.style.top = lower.offsetHeight+'px';
max.style.top = lower.offsetHeight+'px';
legend.style.marginTop = min.offsetHeight+'px';
slider.style.height = (lower.offsetHeight + min.offsetHeight + legend.offsetHeight)+'px';
/* correct for 1 off at the end */
if(max.value>(rangemax - 1)) max.setAttribute('data-value',rangemax);
/* write value and labels */
max.value = max.getAttribute('data-value');
min.value = min.getAttribute('data-value');
lower.innerHTML = min.getAttribute('data-value');
upper.innerHTML = max.getAttribute('data-value');
}
function init(slider) {
/* set function vars */
var min = slider.querySelector('.min');
var max = slider.querySelector('.max');
var rangemin = parseInt(min.getAttribute('min'));
var rangemax = parseInt(max.getAttribute('max'));
var avgvalue = (rangemin + rangemax)/2;
var legendnum = slider.getAttribute('data-legendnum');
/* set data-values */
min.setAttribute('data-value',rangemin);
max.setAttribute('data-value',rangemax);
/* set data vars */
slider.setAttribute('data-rangemin',rangemin);
slider.setAttribute('data-rangemax',rangemax);
slider.setAttribute('data-thumbsize',thumbsize);
slider.setAttribute('data-rangewidth',slider.offsetWidth);
/* write labels */
var lower = document.createElement('span');
var upper = document.createElement('span');
lower.classList.add('lower','value');
upper.classList.add('upper','value');
lower.appendChild(document.createTextNode(rangemin));
upper.appendChild(document.createTextNode(rangemax));
slider.insertBefore(lower,min.previousElementSibling);
slider.insertBefore(upper,min.previousElementSibling);
/* write legend */
var legend = document.createElement('div');
legend.classList.add('legend');
var legendvalues = [];
for (var i = 0; i < legendnum; i++) {
legendvalues[i] = document.createElement('div');
var val = Math.round(rangemin+(i/(legendnum-1))*(rangemax - rangemin));
legendvalues[i].appendChild(document.createTextNode(val));
legend.appendChild(legendvalues[i]);
}
slider.appendChild(legend);
/* draw */
draw(slider,avgvalue);
/* events */
min.addEventListener("input", function() {update(min);});
max.addEventListener("input", function() {update(max);});
}
function update(el){
/* set function vars */
var slider = el.parentElement;
var min = slider.querySelector('#min');
var max = slider.querySelector('#max');
var minvalue = Math.floor(min.value);
var maxvalue = Math.floor(max.value);
/* set inactive values before draw */
min.setAttribute('data-value',minvalue);
max.setAttribute('data-value',maxvalue);
var avgvalue = (minvalue + maxvalue)/2;
/* draw */
draw(slider,avgvalue);

<input id="min" class="min" name="min" type="range" step="1" min="0" max="3000" />
<label for="max">Maximum price</label>
<input id="max" class="max" name="max" type="range" step="1" min="0" max="3000" />
</div>
Note that you should keep the step size to 1 to prevent the values to change due to redraws/redraw bugs.

2022 - Accessible solution - 30 second solution to implement
This solution builds off of this answer by #JoostS. Accessibility is something none of the answers have focused on and that is a problem, so I built off of the above answer by making it more accessible & extensible since it had some flaws.
Usage is very simple:
Use the CDN or host the script locally: https://cdn.jsdelivr.net/gh/maxshuty/accessible-web-components/dist/simpleRange.min.js
Add this element to your template or HTML: <range-selector min-range="0" max-range="1000" />
Hook into it by listening for the range-changed event (or whatever event-name-to-emit-on-change you pass in)
That's it. View the full demo here. You can easily customize it by simply applying attributes like inputs-for-labels to use inputs instead of labels, slider-color to adjust the color, and so much more!
Here is a fiddle:
window.addEventListener('range-changed', (e) => {console.log(`Range changed for: ${e.detail.sliderId}. Min/Max range values are available in this object too`)})
<script src="https://cdn.jsdelivr.net/gh/maxshuty/accessible-web-components#latest/dist/simpleRange.min.js"></script>
<div>
<range-selector
id="rangeSelector1"
min-label="Minimum"
max-label="Maximum"
min-range="1000"
max-range="2022"
number-of-legend-items-to-show="6"
/>
</div>
<div>
<range-selector
id="rangeSelector1"
min-label="Minimum"
max-label="Maximum"
min-range="1"
max-range="500"
number-of-legend-items-to-show="3"
inputs-for-labels
/>
</div>
<div>
<range-selector
id="rangeSelector2"
min-label="Minimum"
max-label="Maximum"
min-range="1000"
max-range="2022"
number-of-legend-items-to-show="3"
slider-color="#6b5b95"
/>
</div>
<div>
<range-selector
id="rangeSelector3"
min-label="Minimum"
max-label="Maximum"
min-range="1000"
max-range="2022"
hide-label
hide-legend
/>
</div>
I decided to address the issues of the linked answer like the labels using display: none (bad for a11y), no visual focus on the slider, etc., and improve the code by cleaning up event listeners and making it much more dynamic and extensible.
I created this tiny library with many options to customize colors, event names, easily hook into it, make the accessible labels i18n capable and much more. Here it is in a fiddle if you want to play around.
You can easily customize the number of legend items it shows, hide or show the labels and legend, and customize the colors of everything, including the focus color like this.
Example using several of the props:
<range-selector
min-label="i18n Minimum Range"
max-label="i18n Maximum Range"
min-range="5"
max-range="555"
number-of-legend-items-to-show="6"
event-name-to-emit-on-change="my-custom-range-changed-event"
slider-color="orange"
circle-color="#f7cac9"
circle-border-color="#083535"
circle-focus-border-color="#3ec400"
/>
Then in your script:
window.addEventListener('my-custom-range-changed-event', (e) => { const data = e.detail; });
Finally if you see that this is missing something that you need I made it very easy to customize this library.
Simply copy this file and at the top you can see cssHelpers and constants objects that contain most of the variables you would likely want to further customize.
Since I built this with a Native Web Component I have taken advantage of disconnectedCallback and other hooks to clean up event listeners and set things up.

Changes:
1. allow different min/max/step for two inputs
2. new property 'maxGap'
3. added events 'input'/'change'
4. dropped IE/OldEdge support

Dual slider using HTML, CSS, JS
I have modified this slider using embedded ruby so we can save previously applied values using params in rails.
<% left_width = params[:min].nil? ? 0 : ((params[:min].to_f/100000) * 100).to_i %>
<% left_value = params[:min].nil? ? '0' : params[:min] %>
<% right_width = params[:max].nil? ? 100 : ((params[:max].to_f/100000) * 100).to_i %>

I'm trying to build a simple website that let's you click 6 different buttons. Each click of the button is supposed to trigger the display of specific content (as an img file). Clicking each of the six buttons should lead to different content. I have managed to achieve this part via Javascript getElementById.
However, to add a bit more complexity, I want to implement sequential decision making. Meaning that clicking Button "1" and THEN clicking Button "2" (or 3-6 for that matter) should each lead to the display of other specific content. Likewise clicking Button "1", then "2" and then "1" again should also display specific content. My sequential decision making is supposed to be limited to only two buttons interacting until the end of the decision is reached. So essentially, something like 1 -> 2 -> 3 can not happen, but 3 -> 6 -> 3 can happen. I hope it's not too complicated what I'm trying to do.
Anyway, here's some code I wrote trying to achieve this, but I'm fairly sure that my toggle function is not the correct way to go about it as I'm essentially simply placing pictures above each other and there is no sequency to any of the decisions made. I think to achieve this, I would need to chain the clicks, but I'm completely lost as to how to achieve that. Any help is greatly appreciated.

Though I can not provide you with a firm solution, I can however offer a small example which illustrates how to incorporate an array which tracks the buttons that have been clicked, as well as a way to get certain content from combinations of buttons.
Run the example and try the combinations 363, 254, 521 and 165 to get some results showing up. I've tried my best to show what the produced output is.
I'd suggest that you take a look at it and ask any questions if you have them. I'll check in to see if you do.
$(document).ready(function() {
/**

* The $display and $clickedButtons are just to output
* the values that are stored.

const $removeButton = $('#remove-button');
/**

* The combination of the values will then later represent the key.
*/
const values = [];
/**

$display.addClass('hidden');
}
}

Edit
In the spirit of showing is better than telling; your last comment was about having a loose combination of numbers. This adds another layer of complexity.
Objects can only have keys that are strings (or Symbols) to get and set values. But in your case you'll want an array of numbers which represent the keys in any order, so plain objects are not suitable anymore.
The solution for this is the Map object. This object can have any type of key and value. So we can make a link between a combination of numbers and the images they represent (hence the name "map").
The example below uses this method. I've written a function that checks if an array of numbers is a match with any combination in the map. And if it does it return an array of images, referring to your previous comment.
Check it out. I believe this one to be more complex, so once more feel free to ask questions.
/**
* Create a Map instance.
*/
const combinations = new Map();
/**
* Values and keys are added with the set() method.
* This could still be improved with a loop setting each
* combination / images pair.
*/
combinations.set([3, 3, 6], ['https://www.fillmurray.com/200/200', 'https://www.fillmurray.com/200/200']);
combinations.set([2, 4, 5], ['https://www.fillmurray.com/220/220', 'https://www.fillmurray.com/220/220']);
combinations.set([1, 2, 5], ['https://www.fillmurray.com/240/240']);
combinations.set([1, 5, 6], ['https://www.fillmurray.com/300/300', 'https://www.fillmurray.com/300/300', 'https://www.fillmurray.com/300/300']);
const tryCombination = (key, combinations) => {
/**
* Loop over every combination.
* [combination, images] exposes the key-value pair,
* it's just a syntax to write fewer lines
*/
for (const [combination, images] of combinations) {
/**
* Create an array for the matches. If a number of the
* combination is in the given key, then that number
* will be pushed to the matches list. In the end,
* if everything matches, we should have just as many
* matches as numbers in the combination. That way
* we know if a key is correct.
*/
const matches = [];
/**
* We'll do some manipulation on the combination array,
* so to keep it intact we make a copy and manipulate that instead.
*/
const combinationCopy = Array.from(combination);
/**
* Count backwards through the combination array.
* Backwards counting is necessary when you remove items
* from the array while looping. I'd suggest you look
* into that subject.
*/
for (let i = combinationCopy.length - 1; i >= 0; i--) {
/**
* Get the current number we're looping over.
*/
const number = combinationCopy[i];
/**
* If that number is in the key array..
*/
if (key.includes(number)) {
/**
* ..then push that number to the matches array..
*/
matches.push(number);
/**
* ..and remove it from the copied combination array.
* We do this to prevent duplicate hits for cases
* where you have multiple occurrences of the same number,
* like [3, 3, 6]. When the first 3 hits, it will be removed.
* Then we have [3, 6] and we know we only need one more
* 3 and a 6.
*/
combinationCopy.splice(i, 1);
}
}
/**
* Now if every number has been matched correctly, then
* the amount of matches should be the same as the length
* of the combination. If that is the case, return the
* images. Otherwise, do nothing.
*/
if (matches.length === combination.length) {
return images;
}
}
/**
* If there are no matches, just return false, notifying the
* user that the combination is incorrect.
*/
return false;
};
console.log(tryCombination([5, 4, 2], combinations)); // Hit!
console.log(tryCombination([5, 1, 6], combinations)); // Hit!
console.log(tryCombination([2], combinations)); // Fail!
console.log(tryCombination([5, 4, 4], combinations)); // Fail!
console.log(tryCombination([3, 6, 3], combinations)); // Hit!
So I want to replace the text inside of an input field with a h1 tag as soon as the user hits submit because i want the text to have an animation but i can't animate the text inside the text field.
I linked the code pen project version of it to make it easier then organizing all the code in here. I added all the code I had so I wouldn't leave anything out although some of it may be irrelevant.
Basically I want the h1 tag to appear exactly where the input text was so it looks like nothing ever got replaced.

You want to put H1 below the input.
Then you make the text input transparent. Bind the input value to h1.
So in effect when user clicks and type, they are selecting the input and changing its value, but it's transparent, to be shown by the h1 below the input that you will eventually animate.
Also because you mentioned you want it to display correctly in all platforms. You then have to be cognisant of the default behaviours of DOM and CSS properties. If you alter them to get what you want without knowing its natural order, you can get unexpected behaviour and reduce cross-browser compatibility. I have made changes to reflect that.

I am having issues transferring a value to an input field.
Within the snippet linked their is a heading with the value hydrogen and to the bottom left their is a boiling point heading with a input field for celcius.
I'm trying to achieve a scenario whereby you move the slider along using the buttons and at each value the heading changes to a different element and the input value for just the celcius boiling point changes.
I can't get this to work though. The buttons are working to make the slider move left and right, but for whatever reason i cant get the value to appear within the input field or change the heading. I've displayed the code i have already to get the buttons to move the slider and a snippet of what i thought would allow the changes i want to take place when the slider value changes to 2. I cant get it to to work though
Thanks.
You don't show your HTML, but I presume that slider is an input (text or hidden).
The value attribute is a string, even if you assign it a number, so you need to first convert it to a integer if you want to increment or decrement it, like so:
slider.value = parseInt(slider.value)++ // or --
Note that also you are trying to parseInt(2) down in your main(), which makes no sense as 2 is already an integer.
I have this div ( that contains the content of my website. I would like to make it shake when something doesn't authenticate properly using the jQuery effect.("shake"). However, I can't get it to shake at all. Instead, the div disappears for a period of time and then reappears. This happens regardless of me switching any of the parameters. The only effect that switching the parameter has is changing the duration of the disappearance.
I haven't been able to troubleshoot much (this is literally my first use of jQuery and the only jQuery I anticipate this project utilizing).
The reason the google apps script tag was added (I added it back) is because this project is using Google Apps Script. I'm using it to pull data from a Google Spreadsheet (which avoids paying for and maintaining a database).
The offending jQuery (is currently in the HTML file):
$(document).click(function(){
$("#container").effect( "shake", {times:4}, 1000 );
});
And here's ALL of the code:
function getTournamentInfo(){
google.script.run.withSuccessHandler(setTournamentInfo).grabTournamentInfo()

// insert tournament header
var tournamentBanner = document.createElement("h1");
var tournamentBannerText = document.createTextNode(systemData[0]);
tournamentBanner.appendChild(tournamentBannerText);
document.getElementById("container").insertBefore(tournamentBanner,document.getElementById("maindata"));
//create a space
document.getElementById("container").insertBefore(document.createElement("br"),document.getElementById("maindata"));
//insert chamber header
var chamberBanner = document.createElement("h2");
var chamberBannerText = document.createTextNode(systemData[1]);
chamberBanner.appendChild(chamberBannerText);
document.getElementById("container").insertBefore(chamberBanner,document.getElementById("maindata"));
//insert session header
var sessionNumber = document.getElementById("sessionNameNumber");
var sessionNumberText = document.createTextNode(systemData[2]);
sessionNumber.appendChild(sessionNumberText);
}

var school = [];

}

top: 100% applied to #container is causing your problems. Removing the style doesn't seem to have any effects, so I removed it.
Explanation: When jQuery UI creates the shake effect, it first wraps your element in a div.ui-effects-wrapper, which is a relatively positioned element and copies any position styling (such as top) from your element. It then places your element, stripped of its original position styling, inside of this div, and animates a shake by adjusting its left CSS property. In your case, you had top: 100% applied to your container. When jQuery placed your element inside of its effect-wrapper, the wrapper had both position: relative and top: 100%, which placed your element, the container, off the bottom edge of the screen, out of view. Play around with setting your container styling to something like top: 20px and see the effect this has.
Hope I helped!
