**UPDATED 3/25/20 11:20 est **
The issue I am having now is the code is not using num3 as intended. It is set up like the rest of the code in the HTML and script. This is the set up of my form:
<form name = "arrowCalc">
<table>
<caption>Weight Calculator</caption>
<tr>
<td><label>Draw Length:</label></td>
<td><input type="text" name="txtDraw"></td>
</tr>
<tr>
<td><label>Spine:</label></td>

</tr>
<tr>

</td>
<td>
<input type="radio" id="standardNock" name="nocType" checked="checked" value="6"><label>Standard</label><br>

<tr>

<input type="radio" id="vaneF3" name="vaneType" value="7.5"><label>Fusion 3.0</label>
</td>
</tr>
<tr>
<td><label>Number of Vanes:</label></td>
<td>
<input type="radio" id="vanes3" name="vaneNumber" value="3"><label>3</label><br>
<input type="radio" id="vanes4" name="vaneNumber" value="4"><label>4</label><br>
</td>
</tr>
<tr>
<td></td>
<td><input type="button" value="Calculate" onClick="weightFormula()" align="right"></td>
</tr>
<tr>
<td><label>Weight:</label></td>
<td><input type="text" name="txtRes"></td>
</tr>
</table>
This is my function:
function weightFormula() {
var num1, num2, num3, num4, num5, num6, num7, res;
num1=Number(document.arrowCalc.txtDraw.value)-.5;
num2=document.querySelector('input[name=spineType]:checked').value;
num3=document.querySelector('input[name=nocType]:checked').value;
num4=Number(document.arrowCalc.txtInsert.value);
num5=Number(document.arrowCalc.txtBroad.value);
num6=document.querySelector('input[name=vaneType]:checked').value;
num7=document.querySelector('input[name=vaneNumber]:checked').value;
res=(num1*num2)+num4+num5+(num6*num7)+10+num3;
document.arrowCalc.txtRes.value=res;
}
With the exception as num3, all other variables are working as expected. If I would make num3 a text input or a dropdown box, the code also works as expected. Currently num3 will just add the value to the end of the total number. For instance if I am expecting an answer of 775.25 and I select the Standard nock (value of 6) the answer would be 769.256. The same thing happens when I move num3 to other spots in the res= line, it will just place the values at the end of the decimal.
The numbers I have been using for this are:
Draw Length (num1) = 29
Spine (num2) = 12.5 (spine250)
Nock (num3) = 6 (standard)
Insert (num4) = 175
Broadhead (num5) = 200
Vane type (num6) = 7 (Fusion 2.1)
Vane number (num7) = 4
As previously stated, this should equal 775.25
Try using eval()
function weightFormula() {
var num1, num2, num3, num4, num5, num6, num7, res;
num1=document.arrowCalc.txtDraw.value-.5+"";
num2=document.querySelector('input[name=spineType]:checked').value;
num3=document.querySelector('input[name=nocType]:checked').value; /*This is part of the issue*/
num4=document.arrowCalc.txtInsert.value;
num5=document.arrowCalc.txtBroad.value;
num6=document.querySelector('input[name=vaneType]:checked').value;
num7=document.querySelector('input[name=vaneNumber]:checked').value;
debugger;
res=eval(`${num1}*${num2}+${num4}+${num5}+(${num6}*${num7})+10+${num3}`);
document.arrowCalc.txtRes.value=res;
}
function weightFormula() {
var num1, num2, num3, num4, num5, num6, num7, res;
num1=document.arrowCalc.txtDraw.value-.5+"";
num2=document.querySelector('input[name=spineType]:checked').value;
num3=document.querySelector('input[name=nocType]:checked').value; /*This is part of the issue*/

document.arrowCalc.txtRes.value=res;

I created a table with some checkboxes and I want to create a JavaScript that remove the ones I don't want there but I'm stuck in the JavaScript part. Could you please help me in this small challenge? Thanks!
<table class="isTable">
<tbody>
<tr>
<td>
<input id="firstCheckBox" type="checkbox" name="number1" value="All">
<label for="firstCheckBox">All</label>
</td>
</tr>
<tr>
<td>
<input id="secondCheckBox" type="checkbox" name="number2" value="Some text">
<label for="secondCheckBox">Some text</label>
</td>
</tr>
<tr>
<td>
<input id="thirdCheckBox" type="checkbox" name="number3" value="1st to be removed">
<label for="thirdCheckBox">1st to be removed</label>
</td>
</tr>
<tr>
<td>
<input id="fourthCheckBox" type="checkbox" name="number4" value="Some other text">
<label for="fourthCheckBox">Some other text</label>
</td>
<tr>
<td>
<input id="fifthCheckBox" type="checkbox" name="number5" value="2nd to be removed">
<label for="">2nd to be removed</label>
</td>
<tr>
<td>
<input id="fifthCheckBox" type="checkbox" name="number6" value="Some other text again">
<label for="">Some other text again</label>
</td>
<tr>
<td>
<input id="sixthCheckBox" type="checkbox" name="number7" value="3rd to be removed">
<label for="">3rd to be removed</label>
</td>
</tr>
</tbody>
</table>
The JS part done so far, but the way I tried to removed the tr doesn't work
let findTableOfCheckBoxes = document.getElementsByClassName('.isTable');
for (let i = 0; i < findTableOfCheckBoxes.length; i++) {
let selectTr = document.getElementsByTagName("tr")[2];
selectTr.parentNode.removeChild(selectTr);
}
You're committing the cardinal sin of assuming your selector is finding elements. It's not, because you need isTable not .isTable when using getElementsByClassName() which, since it's about classes, assumes the . for you.
There's also a more modern, cleaner way to achieve what you need. Follows:
document.querySelectorAll('.isTable').forEach(tbl => {
let row = tbl.querySelector('tr:nth-child(3)');
row && row.remove();
});
You added "." character for the getElementsByClassName. Just remove it.
let findTableOfCheckBoxes = document.getElementsByClassName('isTable');
let findTableOfCheckBoxes = document.getElementsByClassName('isTable');
for (let i = 0; i < findTableOfCheckBoxes.length; i++) {
let selectTr = document.getElementsByTagName("tr")[2];
selectTr.parentNode.removeChild(selectTr);
}
<table class="isTable">

How can I make a server request when the contect of a table cell is changed?
i.e. on a table like this:
<form class="formclass">
<table border="1" style="float:left">
<tr>
<td><input type="text" name="country" value="USA" readonly/></td>
<td>
<input type="radio" name="enabled" value="1" checked>enabled
<input type="radio" name="enabled" value="0">disable
</td>
</tr>
<tr>
<td><input type="text" name="country" value="England" readonly/></td>
<td>
<input type="radio" name="enabled" value="1" checked>enabled
<input type="radio" name="enabled" value="0">disable
</td>
</tr>
<tr>
<td><input type="text" name="country" value="Sweden" readonly/></td>
<td>
<input type="radio" name="enabled" value="1" checked>enabled
<input type="radio" name="enabled" value="0">disable
</td>
</tr>
</table>
</form>
I tried adding an onchange function
$('.formclass').change(function() {console.log("succes")});
but this only works when every row is it's own form.
<form class="formclass">
<table border="1" style="float:left">
<tr>
<td><input type="text" name="country" value="USA" readonly/></td>
<td>
<input type="radio" name="enabled" value="1" checked>enabled
<input type="radio" name="enabled" value="0">disable
</td>
</tr>
</table>
</form>
<form class="formclass">
<table border="1" style="float:left">
<tr>
<td><input type="text" name="country" value="Englang" readonly/></td>
<td>
<input type="radio" name="enabled" value="1" checked>enabled
<input type="radio" name="enabled" value="0">disable
</td>
</tr>
</table>
</form>
<form class="formclass">
<table border="1" style="float:left">
<tr>
<td><input type="text" name="country" value="Sweden" readonly/></td>
<td>
<input type="radio" name="enabled" value="1" checked>enabled
<input type="radio" name="enabled" value="0">disable
</td>
</tr>
</table>
</form>
However this makes the styling really bad.
I just want a table where if on cell is changed it makes a server request with the data of that row. So here the country and radio button value if someone changes the the radio button.
Attach it to inputs instead of form
$('input[type=radio]').change(function() {console.log("succes")});
I am building a personality assessment page. However, I am seriously stuck and at this point, I cannot even understand where I went wrong. (Psychology student here, so this world is new to me.)
<form action="answer.html" method="get" class="personality_form" id="personality_form" onsubmit="return validateForm()">
<tr>
<td>Statement1</td>
<td><input type="radio" name="st1" class="dis" value="-1"></td>
<td><input type="radio" name="st1" class="na" value="0"></td>
<td><input type="radio" name="st1" class="agg" value="1"></td>
</tr>
<tr>
<td>Statement2</td>
<td><input type="radio" name="st2" class="dis" value="-1"></td>
<td><input type="radio" name="st2" class="na" value="0"></td>
<td><input type="radio" name="st2" class="agg" value="1"></td>
</tr>
<tr>
<td>Statement3</td>
<td><input type="radio" name="st3" class="dis" value="-1"></td>
<td><input type="radio" name="st3" class="na" value="0"></td>
<td><input type="radio" name="st3" class="agg" value="1"></td>
</tr>
<tr>
<td>Statement4</td>
<td><input type="radio" name="st4" class="dis" value="-1"></td>
<td><input type="radio" name="st4" class="na" value="0"></td>
<td><input type="radio" name="st4" class="agg" value="1"></td>
</tr>
<tr>
<td>Statement5</td>
<td><input type="radio" name="st5" class="dis" value="-1"></td>
<td><input type="radio" name="st5" class="na" value="0"></td>
<td><input type="radio" name="st5" class="agg" value="1"></td>
</tr>
<tr>
<th colspan="4"><button type="submit" onclick="get();">Get Results</button></th>
</tr>
</form>
Now I am adding here following script:
function get() {
var res1 = document.getElementsByName("st1").value;
var res2 = document.getElementsByName("st2").value;
var x = res1 + res2;
if (x < 0) {
document.getElementById('result').innerHTML = x;
}
}
And answer.html consists of
<div id="result"></div>
I cannot seem to get the value no matter how hard I try. I've tried doing id="st1_1" and getElementById, but it still won't do it.
Any suggestions or ideas what am I doing wrong?
Thank you
document.getElementsByName returns a NodeList, so there are multiple elements. As a result, it doesn't have a value property so res1 and res2 are undefined.
Try changing document.getElementsByName("st1").value to document.querySelector("[name=\"st1\"]:checked").value. If you get an error message like "TypeError: Cannot read property 'value' of null" then it means that none of the inputs with the name "st1" is checked.
Adding to James Long's answer,
Open the console on the webpage and type
document.getElementsByName("st1");
You will get
[<input type="radio" name="st1" class="dis" value="-1">, <input type="radio" name="st1" class="na" value="0">, <input type="radio" name="st1" class="agg" value="1">]
This indicates that you the above code returns an array. Now to select either of the <input> tags, you can use document.getElementsByName("st1")[0] which will select the first <input>.
To find out which input/s have been selected, iterate over the inputs and find the total sum. If you changed your values to
<input type="radio" name="st#" class="dis" value="1">
<input type="radio" name="st#" class="na" value="2">
<input type="radio" name="st#" class="agg" value="4">
Then if the sum is 1, then first one is selected, if it is 2, then second is selected, if 3 then first two were selected, if 4 then third is selected, if 5 then first and third, 6 then second and third, 7 then all three.
function get() {
var res1 = document.querySelector('input[name="st1"]:checked').value;
var res2 = document.querySelector('input[name="st2"]:checked').value;
console.log("res1="+res1);
console.log("res2="+res2);
var x = parseInt(res1) + parseInt(res2);
// if (x < 0) {
document.getElementById('result').innerHTML = x;
// }
}

Please review working code this may help to resolve an issue. You should not use both "onClick() on submit button" and "OnSubmit on form post" at a time.
click()
This method is a shortcut for in the first two variations and in the third. The click event is sent to an element when the mouse pointer is over the element, and the mouse button is pressed and released. Any HTML element can receive this event. click() event bind with a mouse. There are multiple events available for the mouse.
submit()
submit() This method is a shortcut for .on( "submit", handler ) in the first variation, and .trigger( "submit" ) in the third. This method belongs to form event. There are also more events which are specifically bound with HTML form only.
The submit event is sent to an element when the user is attempting to submit a form. It can only be attached to elements. Forms can be submitted either by clicking an explicit , , or , or by pressing Enter when certain form elements have focus.
$(document).ready(function() {
$(".personality_form").on("submit", function(e) {
e.preventDefault();
getData();
});
function getData() {
var res1 = $("input[name='st1']").val();
var res2 = $("input[name='st2']").val();
var x = parseInt(res1) + parseInt(res2);
if (x < 0) {
$('.result').html(x);
}
}
function validateForm() {
return true;

getElementsByName returns a live nodelist so you can't immediately grab the value. You need to iterate over the nodelist (or get the node you want using array notation) and then add the values.
However, what you might find easier is to use querySelectorAll to pick up all the checked buttons (document.querySelectorAll(":checked")) and iterate over those instead, making sure that you convert the string value to a number on each iteration when you add the values together.
function get() {
var checked = document.querySelectorAll(":checked");
let total = 0;
for (let i = 0; i < checked.length; i++) {
total += Number(checked[i].value);
}
document.getElementById('result').textContent = total;
}
document.querySelector('button').addEventListener('click', get, false);

So, i have a form as below.I want to select all in working when the checkbox(For All Day) is selected. Is there any way i can do it through html or should i go for php or javascript?

<!--on selecting the checkbox below all radio buttons under working must get selected-->
<input type="checkbox" name="day" />All Day
</td>

You won't be able to do this with php, at least without reloading the page or making an Ajax request but this would be impractical. The best option is JavaScript; refer to this question, it solves your problem: How to implement "select all" check box in HTML?
Basically, all you have to do is bind an onClick event on the checkbox "All days" that triggers the JavaScript function. The function then takes the list of checkboxes, iterates through all of them, and checks them. The html (taken from the link I provided) should be similar to this:
<input type="checkbox" onClick="toggle(this)" />All days<br/>
And then the script:
function toggle(source) {
checkboxes = document.getElementsByName('x');
for(var i=0, n=checkboxes.length;i<n;i++) {
checkboxes[i].checked = source.checked;
}
}
The easiest method would be to use a javascript function that would be called upon the All Day check box value changed.
Then your function would be IF checked, run through the list and check all days

Use jQuery for checking/unchecking all week days based on checking/unchecking of "All days":
$(document).ready(function(){
$(':checkbox[name="day"]').click(function(){
if($(this).is(':checked')){
$("input:radio[value='work']").prop("checked", true);
} else {
$("input:radio[value='work']").prop("checked", false);
}
});

// What I want to do is allow the user to select many checkboxes. In order to make a booking the user must select atleast one seat number checkbox(this checkbox has to be one or many of the seat number checkboxes). They can also select child,wheelchair or special diet, but in order to do so, the checkbox that belongs to the corresponding seat number must be checked. If it isnt a validation or popup must occur stating that the seat number must be checked. Meaning that if a user wants to check either special diet, wheelchair or child the seat number must be checked. If the user clicks the submit button without any checkboxes selected than a validation should occur or popup stating that atleast one checkbox must be selected.THis is my current page layout

In my opinion, forget about all the alerts and such, just use arrayed check box keys:
<tr>
<td>Seat 1</td>
<td><input type="checkbox" name="seat1[child]" value="1"></td>
<td><input type="checkbox" name="seat1[wheelchair]" value="1"></td>
<td><input type="checkbox" name="seat1[specialdiet]" value="1"></td>
</tr>
<tr>
<td>Seat 2</td>
<td><input type="checkbox" name="seat2[child]" value="1"></td>
<td><input type="checkbox" name="seat2[wheelchair]" value="1"></td>
<td><input type="checkbox" name="seat2[specialdiet]" value="1"></td>
</tr>
<tr>
<td>Seat 3</td>
<td><input type="checkbox" name="seat3[child]" value="1"></td>
<td><input type="checkbox" name="seat3[wheelchair]" value="1"></td>
<td><input type="checkbox" name="seat3[specialdiet]" value="1"></td>
</tr>
<tr>
<td>Seat 4</td>
<td><input type="checkbox" name="seat4[child]" value="1"></td>
<td><input type="checkbox" name="seat4[wheelchair]" value="1"></td>
<td><input type="checkbox" name="seat4[specialdiet]" value="1"></td>
</tr>
Upon submission your array will look like this:
Array
(
[seat1] => Array
(
[child] => 1
[wheelchair] => 1
)
[seat2] => Array
(
[wheelchair] => 1
)
[seat3] => Array
(
[wheelchair] => 1
[specialdiet] => 1
)
[seat4] => Array
(
[child] => 1
[wheelchair] => 1
[specialdiet] => 1
)
[Add_booking] => Add_booking
)
EDIT:
Based on your clarification, you need some javascript (jQuery):
Demo:
https://jsfiddle.net/9e9embjt/
JavaScript:
$(document).ready(function(){
$(this).on('click',".seat_selector",function() {
var thisBtn = $(this);
var isChk = thisBtn.is(":checked");
var thisWrap = thisBtn.parents('.seat_selector_wrap').find("input[type=checkbox]");
if(isChk)
thisWrap.attr("disabled",false);
else {
thisWrap.attr("disabled",true);
thisBtn.attr("disabled",false);
}
var allSeats = $(".seat_selector");
var disable = true;
$.each(allSeats, function(k,v) {
if($(v).is(":checked")) {
disable = false;
return false;
}
});
$("#submitter").attr('disabled',disable);
});
});
