I want to check via JavaScript whether one of the "li" is checked, if so it should change that line to "green".
<li class="radiobutton">
<span class="name">Toe Brakes -<font color="green"> hold</font></span>
<input name="1" type="radio" value="other" />
</li>

If jquery is an option, it becomes pretty simple.
function checkChanges()
{
$('.radiobutton font').attr('color', 'red');
$('.radiobutton :checked').closest('.radiobutton').find('font').attr('color', 'green');
}
$(function()
{
checkChanges();
$('.radiobutton :radio').on('click', checkChanges);
});
Although I HIGHLY recommend removing the font tag and instead add a class to the li, such as radiobutton-checked which sets the font color to green.
The ab ove code will reset all fonts to red, then find the one radio button with a checked radio inside it, iterate back up to the parent radiobutton (closest) and then find its child font tag and set its color to green. Then anytime a radio button gets clicked, it repeats the above process, thus keeping only the actively checked radio button green.

Java radiobutton if else

I am currently new to web development, how do you get the total value of the chosen radio buttons and store it in an array then the link or page would be different base on the total value. Is it possible in javascript? let's say that the total values of the selected buttons is 50 then it will go to page1 if not it will go to page2 and so on.

jQuery set value of nth-child input field?

I have the following html and I want to set the value of the second radio button in the list to be checked. I know I can do this using the id attribute but how can I do the same
by using the class selector as below and chaining the input field to be checked?
<ul class="myOptionList">
<li>
<input id="1" type="radio" value="1" name="options">
<label >one</label>
</li>
<li>
<input id="2" type="radio" value="2" name="options">
<label >two</label>
</li>
...
</ul>
$(".myOptionList li:nth-child(2)"); // how do i chain input field and set it as checked
Below code may help you.
HTML
<ul class="myOptionList">
<li>
<input id="1" type="radio" value="1" name="options">
<label >one</label>
</li>
<li>
<input id="2" type="radio" value="2" name="options">
<label >two</label>
</li>
jQuery
$(".myOptionList li:nth-child(2)").find('input:radio').prop('checked',true);
For versions of jQuery prior to 1.6, use:
$(".myOptionList li:nth-child(2)").find('input:radio').attr('checked', 'checked');
$(document).ready(function(){
$(".radio1 li:nth-child(4)").find('input:radio').prop('checked',true);
$(".radio2 li:nth-child(2)").find('input:radio').prop('checked',true);
$(".radio li:nth-child(1)").find('input:radio').prop('checked',true);
});

<label >three</label>
</li>
<li>
<input id="4" type="radio" value="4" name="option2">

First child selected:
<ul class="radio">

<input id="2" type="radio" value="2" name="option">
<label >two</label>
</li>
</ul>
First child selected:(same class name)
<ul class="radio">
<li>
<input id="1" type="radio" value="1" name="option4">
<label >one</label>
</li>
<li>
<input id="2" type="radio" value="2" name="option4">
<label >two</label>
</li>
</ul>
</body>
</html>
Even the use of:
$(".myOptionList li:nth-child(2)").find('input:radio').prop('checked',true);
Works apparently, it is just for a case.
It set the checked on all the radio until the last one, that it is set just because it is the last.
A more meaning solution would be to use the .last() to go directly on the radio option you want to set:
$(function(){
// Set the last checked radio
$('.myOptionList li > input[name="options"]').last().prop('checked', true)
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul class="myOptionList">
<li>
<input id="1" type="radio" value="1" checked name="options">
<label >one</label>
</li>
<li>
<input id="2" type="radio" value="2" name="options">
<label >two</label>
</li>
...
</ul>
To ensure it's working properly I set the first radio checked.
But I suggest to change your code in a way that you select the radio on the value attribute.
The benefit of this is that your code will be more clear and easy to understand and change, and more if the order of radios change it will still works.

How to get selected radio button value from visibile HTML area?

I have following HTML with two ULs.
Click
<ul class="plan none">

alert($(".plan input[type='radio']:checked").val());
}
});
My JSFiddle: Sample
Any Idea?
Thanks.
Use this way:
$(".plan:visible").find("input:radio:checked").val();
Snippet
$("#detail_buttons").click(function () {
alert($(".plan:visible").find("input:radio:checked").val());
return false;
});
.none {display: none;}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

</html>
And i got a function that check for "radio is checked and change colour"
function checkChanges()
{
$('.radiobutton font').attr('color', 'red');
$('.radiobutton :checked').closest('.radiobutton').find('font').attr('color', 'green');
}
$(function()
{
checkChanges();
$('.radiobutton :radio').on('click', checkChanges);
});
I want to add to that code a function that uncheck the Radio if its checked and been clicked again (onClick) this should also change the colour back to red.
Few corrections...
Remove the space before the :checked. Change:
$('.radiobutton :checked').closest('.radiobutton').find('font').attr('color', 'green');
To:
$('.radiobutton:checked').closest('.radiobutton').find('font').attr('color', 'green');
You need to use input[type="radio"] here. Change:
$('.radiobutton :radio').on('click', checkChanges);
To:
$('input.radiobutton[type="radio"]').on('click', checkChanges);

How to show selected value of type="radio" on populate?

On clicking on the Populate Values button the div below the button should populate the values of the selected radio buttons of the preferred and home locations respectively
I want to do it unobtrusively without inline JavaScript
<div id="form_block">
<div class="home-location">
<ul>
<li>Home Location</li>
<li>
<input type="radio" name="home-location" value="india" class="radio" id="home-india" /><label
for="home-india">India</label></li>
<li>
<input type="radio" name="home-location" value="usa" class="radio" id="home-usa" /><label
for="home-usa">USA</label></li>
</ul>
</div>
<div class="prefer-location">
<ul>
<li>Preferred Location</li>
<li>
<input type="radio" name="home-preferred" value="india" class="radio" id="preferred-india" /><label
for="preferred-india">India</label></li>
<li>
<input type="radio" name="home-preferred" value="usa" class="radio" id="preferred-usa" /><label
for="preferred-usa">USA</label></li>
</ul>
</div>
<div class="result">
My Home Location is: <span class="home-location-result"></span>and my preferred
location is: <span class="home-location-result"></span>
</div>
<input type="submit" value="Populate Values" id="ss" class="submit" />
Modified your HTML. Provided an id attribute for your result spans
$(function(){
$("#ss").click(function(){
// Find all input elements with type radio which are descendants of element with id `form`
var filt = $("#form_block input:radio");
// Apply a filter to the above object with `name='home-location'` and checked and get the value
var homeVal = filt.filter("[name='home-location']:checked").val();
// same as above
var preferredVal = filt.filter("[name='home-preferred']:checked").val();
// Set the text of the element width id `home-location-result' with the computed value
$("#home-location-result").text(homeVal);
// same as above
$("#preferred-location-result").text(preferredVal);
return false;
});
});
See a working demo
use this it's works for me
<script>
function test()
{
var home= $('input:radio[name=home-location]:checked').val();
document.getElementById("h1").innerHTML=home;
var preferred= $('input:radio[name=home-preferred]:checked').val();
document.getElementById("h2").innerHTML=preferred;
return false;
}
</script>
<form onsubmit="return test();">
<div id="form_block">
<div class="home-location">
<ul>
<li>Home Location</li>
<li>
<input type="radio" name="home-location" value="india" class="radio" id="home-india" /><label
for="home-india">India</label></li>
<li>
<input type="radio" name="home-location" value="usa" class="radio" id="home-usa" /><label
for="home-usa">USA</label></li>
</ul>
</div>
<div class="prefer-location">
<ul>
<li>Preferred Location</li>
<li>
<input type="radio" name="home-preferred" value="india" class="radio" id="preferred-india" /><label
for="preferred-india">India</label></li>
<li>

</ul>
</div>
<div class="result">
My Home Location is: <span class="home-location-result" id="h1"></span>and my preferred
location is: <span class="home-location-result" id='h2'></span>
</div>
<input type="submit" value="Populate Values" id="ss" class="submit" />
</form>
