I have a inputfield and I need to give two trigger. One is dropdown arrow and Another is cancel ("X") image. Here I am creating my inputfield.
My JS
var input = document.createElement("input");
input.className = 'styled-select';
input.style = 'width:30%' ;
input.id = "SearchInput";
input.type = "text";
input.title = "Madd";
input.onclick = TableExpand; // This happening when I clicking on Inputfield
My CSS for Inputfield
* {
box-sizing: border-box;
}
.styled-select {
width: 100px;
height: 20px;
border: 1px solid #95B8E7;
background-color: #fff;
vertical-align: middle;
display: inline-block;
overflow: hidden;
white-space: nowrap;
margin: 0;
padding: 0;
overflow: hidden;
overflow: -moz-hidden-unscrollable;
background: url(combo_arrow.png) no-repeat right white;
position:relative;
border-radius: 5px 5px 5px 5px;
}
.styled-select select {
background: transparent;
-webkit-appearance: none;
width: 100px;
font-size: 11px;
border: 0;
height: 17px;
position: absolute;
left: 0;
top: 0;
}
I need two trigger as I mentioned Arrow and Cross. I am able to give arrow by using background image but don't know how to give Cross image.
Also How I will use this as a trigger. I mean When I click on Cross and Dropdown one it leads me to the one function where I can write my code.
You can put the triggers as absolutely positioned elements on the input field. This way, you can add separate click events on these triggers to be able to perform whatever you want when they are clicked.
Here is an example of what you are trying to achieve:
HTML:
<div id="container">
<input type="text" id="textfield" />
<div id="triggers">
<img class="trigger" src="https://cdn3.iconfinder.com/data/icons/musthave/128/Stock%20Index%20Up.png" id="arrow" />
<img class="trigger" src="https://cdn3.iconfinder.com/data/icons/musthave/128/Remove.png" id="cross" />
</div>
</div>
CSS:
#container {
position: relative;
width: 600px;
}
#textfield {
height:30px;
width: 100%;
}
.trigger{
width: 20px;
}
#triggers {
position: absolute;
right: 0px;
top: 5px;
}
JS:
$(document).ready(function() {
$("#arrow").click(function() {
$("#textfield").val("Arrow was clicked.");
})
$("#cross").click(function() {
$("#textfield").val("Cross was clicked.");
})
})
Here is a working version:
https://jsfiddle.net/1j760ztn/
Your cross and dropdown should be separate buttons. And the javascript you need to listen for them goes like this.
<input type="text" id="theText"><button id="cross"><button id="dropdown">
<script> var cross = document.getElementById('cross'); cross.addEventListener("click", function(){ document.getElementById('theText').innerHTML = 'clicked X' }); </script>

I have a drop down menu I need to make appear and disappear using pure JavaScript (no libraries/jQuery). Thus I am developing a toggle function. However despite trying several approaches, nothing seems to work. My current idea is to create a variable to hold the state of the menu (open or closed). Once the display of the menu changes from "none" to "block", the variable should change from "closed" to "open". Then an event listener would be added to the body element so when anything is clicked, the menu closes (i.e. the display property is changed back to "none").
Unfortunately the above doesn't seem work. When I put the If/else block outside of an event listener it fires when the page loads, but not when the menuToggle variable changes. If I put it or a function inside the menuPlaceholder event listener the menu won't open, probably due to the open and close code being called basically at the same time.
Clearly I am missing something, probably related to program control or function calling. Does anyone have any insights?
The code I am working with is below. Note the alert functions peppered throughout the code are for testing purposes only.
//Puts IDs for search preference selection box into variables
var menuPlaceholder = document.getElementById('searchSelection');
var menuDisplay = document.getElementById('searchOptions');
var boxLabel = document.getElementById('searchLabel');
//Puts IDs for text input box and submission into variables
var searchBoxPlaceholder = document.getElementById('searchInput');
var searchInput = document.getElementById('searchBox');
var submitButton = document.getElementById('submit');
//Adds class to each search option and puts ID of hidde field into variable
var searchPrefSubmission = document.getElementsByClassName('buttonSearch');
var hiddenInput = document.getElementById('searchChoice');
//Global variable to indicate whether searchOptions menu is opened or closed
var menuToggle = "closed";
//Closes element when one clicks outside of it.
function hideOnClickOutside(element) {
const outsideClickListener = event => {
if (!element.contains(event.target) && isVisible(element)) { // or use: event.target.closest(selector) === null
element.style.display = 'none'
removeClickListener()
}
}
const removeClickListener = () => {
document.removeEventListener('click', outsideClickListener)
}
document.addEventListener('click', outsideClickListener)
}
const isVisible = elem => !!elem && !!( elem.offsetWidth || elem.offsetHeight || elem.getClientRects().length )
//When the placeholder box is clicked, the option menu appears
menuPlaceholder.addEventListener('click', function (event){
menuDisplay.style.display = "block";
menuToggle = "open";
//Add click event to searchPref buttons
for (i = 0; i < searchPrefSubmission.length; i++) {
//Assigns value of the button to both the hidden input field and the placeholder box
searchPrefSubmission[i].addEventListener('click', function(event) {
hiddenInput.value=this.value;
boxLabel.innerHTML = this.value;
menuDisplay.style.display = "none";
menuPlaceholder.style.display = "inline-block";
});
}
});
//This code causes the text input box of the search form to appear when the background box is clicked
searchBoxPlaceholder.addEventListener('click', function(event){
searchInput.style.display = "inline";
submitButton.style.display = "inline";
//hideOnClickOutside(menuDisplay);
});
if (menuToggle == "open"){
document.body.addEventListener('click', function(event){
alert('Foo!');
})
}else{
alert('Boo!');
}
/*function toggleMenu () {
//menuDisplay.style.display = "none";
alert('Boo!');
menuToggle = "closed";

Some issues:
Adding event listeners within an event listener is in most cases a code smell: this will add those inner listeners each time the outer event is triggered. Those listeners remain attached, and so they accumulate. So, attach all event handlers in the top-level script, i.e. on page load, and then never again.
The if ... else at the end will execute on page load, and then never again. So the value of menuToggle is guaranteed to be "closed". You need to put that if...else switch inside the handler, so that it executes every time the event triggers, at which time the menuToggle variable will possibly have a modified value.
The body element does not stretch (by default) over the whole window. If you want to detect a click anywhere on the page, you should attach the listener on the document element itself, not on document.body.
When the click on the menu placeholder is handled, you should avoid that this event "bubbles" up the DOM tree up to the document, because there you have the other handler that wants to hide the menu again. You can do this with event.stopPropagation().
The global variable is not absolutely necessary, but if you use it, then I would call it menuVisible and give it a boolean value: false at first, and possibly true later.
For actually toggling the menu, I would create a function, which takes the desired visibility (false or true) as argument, and then performs the toggle.
Do not use undeclared variables, like the for loop variable i. Define it with let.
Here is your code with those changes implemented. Of course, there is still a lot that could be improved, but I believe that goes beyond the scope of this question:
var menuPlaceholder = document.getElementById('searchSelection');
var menuDisplay = document.getElementById('searchOptions');
var boxLabel = document.getElementById('searchLabel');
var searchBoxPlaceholder = document.getElementById('searchInput');
var searchInput = document.getElementById('searchBox');
var submitButton = document.getElementById('submit');
var searchPrefSubmission = document.getElementsByClassName('buttonSearch');
var hiddenInput = document.getElementById('searchChoice');
// Changed name and type of global variable:
var menuVisible = false;
// Removed some functions ...
menuPlaceholder.addEventListener('click', function (event){
// Use new function for actually setting the visibility
toggleMenu(!menuVisible);
// Avoid that click event bubbles up to the document level
event.stopPropagation();
});
// Add these event handlers on page load, not within another handler
// Define loop variable with let
for (let i = 0; i < searchPrefSubmission.length; i++) {
//Assigns value of the button to both the hidden input field and the placeholder box
searchPrefSubmission[i].addEventListener('click', function(event) {
hiddenInput.value = this.value;
boxLabel.innerHTML = this.value;
// Use the new function for setting the visibility
toggleMenu(false);
menuPlaceholder.style.display = "inline-block";
});
}
searchBoxPlaceholder.addEventListener('click', function(event){
searchInput.style.display = "inline";
submitButton.style.display = "inline";
});
// Bind handler on document itself, and call new function
document.addEventListener('click', function(event) {
toggleMenu(false);
});
// new function to perform the toggle
function toggleMenu(show) {
menuDisplay.style.display = show ? "block" : "none";
menuVisible = show;

I am creating a way to edit dynamic content. I found a question on here that got me started in terms of changing text (spans in my case) into input fields.
Currently, I can't figure out the following issue. When you click "Edit" (on the right side) the input fields replace the span (this is what I want), but when when you click outside of the input the input fields add new span fields instead of replacing the input fields.
I am wanting the styling and the fields to constantly stay in their original place.
Does anyone see what I am doing wrong?
var projID = '';
//Obtaining ID and Editing the projects
$(document.body).on('click', '.recEdit', '[data-editable]', function() {
projID = $(this).parent().data('recid');
console.log('Project ID is..... ' + projID);
var $el = $(this).parent().children().find('span');
var $input = $('<input/>').val( $el.text() );
$el.replaceWith( $input );
var save = function(){
var $p = $('<span data-editable class="recBaseFormat" />').text( $input.val() );
$input.replaceWith( $p );
};
/**
We're defining the callback with `one`, because we know that
the element will be gone just after that, and we don't want
any callbacks leftovers take memory.
Next time `p` turns into `input` this single callback
will be applied again.

$input.one('blur', save).focus();

This code could definitely be optimized, but it should get you going in the right direction. There were a few issues with your code. The issue I mentioned above, which is that your selector was only targeting the last span element within the parent element. We can solve that by using the each method to loop over every span within the parent. Another issue is that you were losing the classes for your spans when you were replacing them with inputs. I've solved that by saving a list of classes for each span before replacing them with an input so that they can be reapplied when they are converted back to spans. Finally, you were firing the save function for all inputs on blur of any input, meaning that the user would only be able to edit one span and then when they clicked out, all inputs would have been converted back. Instead, now it will only convert back when you unfocus each specific input.
var projID = '';
//Obtaining ID and Editing the projects
$(document.body).on('click', '.recEdit', '[data-editable]', function() {
projID = $(this).parent().data('recid');
console.log('Project ID is..... ' + projID);
$(this).parent().children().find('span').each(function() {
var classList = $(this).attr('class');
$input = $('<input/>').val($(this).text());
$(this).replaceWith($input);
$input.on('blur',function() {
$(this).replaceWith('<span data-editable class="' + classList + '">' + $(this).val() + '</span>');
});
});

Finally, as others have mentioned, another option would be to use the contenteditable attribute on your spans. This is an HTML solution for editing HTML elements that are not editable by default. It essentially does the same thing you're trying to do with Javascript, but it's much cleaner. It also has very good browser support. One drawback to this solution would be that it will not be immediately clear to the user that the element is editable like it would be with an actual button that says "Edit." But there are some solutions for that as well.
<span contenteditable="true">You can edit me</span>
You could use juste the contenteditable attribute toggle each click !
Div with the id is clicking, the div with class is not clicking. By clicking div I want to change the color. If the color input within the div class is not working, if it is out of div class it works normally. How do I fix this?
var div = document.getElementsByTagName("div");
var divCount = div.length;
var clickedDivId;
for (var i = 0; i < divCount; i += 1) {
div[i].onclick = function(e) {
if (e.target.id) alert(this.id);
clickedDivId = this.id;
e.stopPropagation();
};
}
function BackgroundColor(){
var x = document.getElementsByClassName("backgroundcolor")[0].value;
document.getElementById(clickedDivId).style.backgroundColor = x;
}
#divid{
width: 450px;
height: 170px;
margin: 10px;
padding: 10px;
background-color: blue;
}
.divclass{
width: 450px;
height: 170px;
margin: 10px;
padding: 10px;
background-color: blue;
}
<div class="divclass">
<input type="color" class="backgroundcolor" onchange="BackgroundColor()">
</div>
<div id="divid"></div>
The click event is firing for both divs, but your handler only shows the alert if the clicked div has an id, which the first one doesn't have.
You are also using old APIs (getElementsByTagName and getElementsByCalssName) that should really not be used anymore and the solution is much simpler that what you've done:
let color = document.querySelector(".backgroundcolor"); // Get reference to color input
let targetDiv = document.getElementById("divid"); // Get reference to second div
// Set up click event handler on the document
document.addEventListener("click", function(evt){
// Check to see if event originated at a div
if(evt.target.nodeName === "DIV"){
alert("You clicked a div!"); // Act accordingly
}
});
// Set up change event on color input
color.addEventListener("change", function(evt){
// Set color of target div
targetDiv.style.backgroundColor = color.value;
});
#divid{
width: 450px;
height: 170px;
margin: 10px;
padding: 10px;
background-color: blue;
}
.divclass{
width: 450px;
height: 170px;
margin: 10px;
padding: 10px;
background-color: blue;
}
<div class="divclass">
<input type="color" class="backgroundcolor">
</div>
<div id="divid">
</div>
function BackgroundColor(){
var x = document.getElementById("backgroundcolor1").value;
document.getElementById("clickedDivId").style.backgroundColor = x;
}
#divid{
width: 450px;
height: 170px;
margin: 10px;
padding: 10px;
background-color: blue;
}
.divclass{
width: 450px;
height: 170px;
margin: 10px;
padding: 10px;
background-color: blue;
}
<div id="clickedDivId" class="divclass">
<input type="color" id="backgroundcolor1" onclick="BackgroundColor()">
</div>

It is better to use ID. I guess this is what you want.
By keep changing the color the background will change as well.
let slider = document.getElementById("slider");
let rightBtn = document.getElementById("rightbutton");
let leftBtn = document.getElementById("leftbutton");
let element = document.getElementById("elementtype").innerHTML;
let celciusBoiling = document.getElementById("celciusboiling").value;
let chlorine = ["Chlorine", 100, 200];
function moveSliderRight() {
if (rightBtn.onclick) {
slider.value++;
}
}
function moveSliderLeft() {
if (leftBtn.onclick) {
slider.value--;
}
}
function main() {
moveSliderRight();
moveSliderLeft();
if (slider.value == parseInt(2)) {
element = chlorine[0];
celciusBoiling = chlorine[1];
}
}
main();

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.
What I need to do is similar to this post, but I need the user to be able to change the Pseudo Element using a custom field. Still learning JavaScript and this has been a struggle!
User needs ability to change ~ border-right: 500px solid #4679BD;
The custom field is ~ $angle = get_field('contact_angle_color');
Here is my code without my failed JavaScript attempts:
.relative-wrap {
position: relative;
min-height: 150px;
}
.triangle-down-right {
width: 50%;
height: 0;
padding-top: 54%;
overflow: hidden;
position: absolute;
top: 0;
right: 0;
}
.triangle-down-right:after {
content: "";
display: block;
width: 0;
height: 0;
margin-top:-500px;
border-top: 500px solid transparent;
border-right: 500px solid #4679BD;
}
<div class="triangle-down-right"></div>
I could not understand the part about custom field, but if you are planning on having unlimited control over pseudo-elements, well, good luck with that. Currently, manipulating pseudo-elements with Javascript is possible through injecting inline css into DOM as described in this post, but it is not recommended unless, of course, you absolutely have to.
So, the other way to change pseudo-elements is to add/remove/modify class names on the element. Please see the example code below and the JSFiddle: https://jsfiddle.net/9w4d6mts/
HTML:
<input type="button" id="direction" value="Change Direction">
<br>
<input type="button" id="color" value="Change Color">
<div id="demo" class="triangle-down-right alt"></div>
CSS:
.relative-wrap {
position: relative;
min-height: 150px;
}
.triangle-down-right,
.triangle-down-left {
width: 50%;
height: 0;
padding-top: 54%;
overflow: hidden;
position: absolute;
top: 0;
right: 0;
}
.triangle-down-right:after,
.triangle-down-left:after {
content: "";
display: block;
width: 0;
height: 0;
margin-top:-500px;
border-top: 500px solid transparent;
}
.triangle-down-right:after {
border-right: 500px solid #4679BD;
}
.triangle-down-left:after {
border-left: 500px solid #4679BD;
}
.triangle-down-right.alt:after,
.triangle-down-left.alt:after {
border-color: transparent #D4679B transparent;
}
JS:
document.getElementById('direction').addEventListener('click', function(){
var d = document.getElementById('demo');
d.className = (d.className.replace(' alt','') === "triangle-down-right") ? d.className.replace('right','left') : d.className.replace('left','right');
});
document.getElementById('color').addEventListener("click", function(){
var d = document.getElementById('demo');
console.log(d.className);
d.className = (d.className.slice(-3) === "alt") ? d.className.replace(' alt','') : d.className + ' alt';
});
Basically, we are preparing the classes in CSS beforehand and switch them with Javascript based on user interaction. That's it.
