I want to change the src attribute of images inside checkboxes based on if they are checked or not. The checking if checked works but the .attr("src") is always undefined.
How do i get the img inside the checkbox ?
cboxes.each(function() {
cb = $(this);
cbImg = cb.find("img");
if (cb.is(':checked')) {
alert(cbImg.attr("src")); //returns undefined
cbImg.attr("src", "css/img/checkbox_fylld.png");
} else {
cbImg.attr("src", "css/img/checkbox_ofylld.png");
}
});
And the HTML
<ul class="nav-justified">
<li>
<label>
<input class="ageSelect" type="radio" id="timeSpan" name="timeSpan" value="0">
<img class="ageSelectImg" src="css/img/checkbox_ofylld.png" />

</ul>
$(document).ready(function(){
$('.ageSelect').each(function() {
cb = $(this);
cbImg = cb.next("img");
if (cb.attr('selected')) {
alert(cbImg.attr("src"));//returns undefined
cbImg.attr("src", "css/img/checkbox_fylld.png");
} else {
cbImg.attr("src", "css/img/checkbox_ofylld.png");
}
});

You do not have any checkboxes. They are radio buttons.
However, here is the code:
Problem is your images are not inside your checkboxes. Checkbox inputs are self-closing tags (also you should terminate them with />).
Instead of .find("img") use .next("img").
One last important thing : you need to wrap your image handling inside an event listener:
$("input[name=\"timeSpan\"").on("change", function() {...});
so the code is executed every time a change is made to the radio input.
$("input[name=\"timeSpan\"").on("change", function() {
$("input[name=\"timeSpan\"").each(function() {
var cbImg = $(this).next("img");
if ($(this).is(':checked')) cbImg.attr("src", "http://www.clker.com/cliparts/8/8/c/0/1197121244407718078webmichl_powerbutton_2_states_%28_on_off_%29_1.svg.med.png");
else cbImg.attr("src", "https://www.windmobile.ca/images/default-source/icons/icons---koray/power-on-off.jpg");
});

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.

<ul class="myOptionList">

<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);

</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.
I have a code already working which calculates the sum of the radio buttons. I changed my mind in one of the radio button group and decided to make it a checkbox. When I tick items on the checkbox, the sum returns NaN. What would I add/change in my jquery in order for it to recognize the checkbox value?
Here's my code:
JQuery
< script type = "text/javascript" >
function calcscore() {
$(".calc:checked").each(function() {
score += parseInt($(this).val(), 10);
});
$('#price').text(score.toFixed(2));
$("input[name=sum]").val(score)
}
$().ready(function() {
$(".calc").change(function() {
calcscore()
});
});
< /script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<li>
<label>
<input class="calc" type="radio" name="rad1" id="rad1" />
</label>
<input type="hidden" name="rad1" value="100">
</li>
<li>
<label>
<input class="calc" type="checkbox" name="check1" id="check1" value="200" />
</label>
<input type="hidden" name="check1" value="200">
</li>
<p>Total: PHP <span id="price">0</span>
</p>
Appreciate all the help.
This code code should answer your question:
function calcscore() {
score = 0;
$(".calc:checked").each(function () {
score += Number($(this).val());
});
$("#price").text(score.toFixed(2));
$("#sum").val(score)
}
$().ready(function () {
$(".calc").change(function () {
calcscore()
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<li>
<label>
<input class="calc" type="radio" name="rad1" id="rad1" value="100" />
</label>
</li>
<li>
<label>
<input class="calc" type="checkbox" name="check1" id="check1" value="200" />
</label>
</li>
<input type="hidden" name="sum" id="sum" value="0">
<p>Total: PHP <span id="price">0</span>
</p>
for your markup and usecase as it stands now in the question.try this
$('.calc').on('click', function() {
var sum = 0;
$('.calc:checked').each(function() {
sum += Number($(this).parent().next().val())
})
$('#price').text(sum)
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<li>
<label>
<input class="calc" type="radio" name="rad1" id="rad1" />
</label>
<input type="hidden" name="rad1" value="100">
</li>
<li>
<label>
<input class="calc" type="checkbox" name="check1" id="check1" value="200" />
</label>
<input type="hidden" name="check1" value="200">
</li>
<p>Total: PHP <span id="price">0</span>
</p>
try this,you dont need hidden fields for values.i removed them and used value property of checkbox.
$('.calc').on('click', function() {
var sum = 0;
$('.calc:checked').each(function() {
sum += Number($(this).val())
})
$('#price').text(sum)
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<li>
<label>
<input class="calc" type="checkbox" name="check1" value="100" id="rad1" />
</label>
</li>
<li>
<label>
<input class="calc" type="checkbox" name="check1" value="200" id="check1" value="200" />
</label>
</li>
<p>Total: PHP <span id="price">0</span>

I know this question had a lots of related resources. But, Still i need a perfect solution.
I have generated five number of radio buttons group dynamically. Each group holds upto five radio buttons. I have validated "none checked in" and "at least one checked in feature" as an individual group.
My question is, How do I validate whether "All the groups are checked"
for ref:
My code Below:
var names = [];
$('input[type="radio"]').each(function() {
// Creates an array with the names of all the different checkbox group.
names[$(this).attr('name')] = true;
});
// Goes through all the names and make sure there's at least one checked.
for (name in names) {
var radio_buttons = $("input[name='" + name + "']");
if (radio_buttons.filter(':checked').length == 0) {
alert('none checked in ' + name);
}
else{
// At least one checked
var val = radio_buttons.val();
}
}
I need to redirect to other page when all the radio button groups are checked. Its a bit simple. But, look complex for me.
Please Help.
UPDATE
My generated HTML for first two groups.
<div class="row">
<div class="optionsContainer"><div id="ratingContainer">
<ul class="0">
<li onclick="checkThis(this);"><div class="ui-radio"><input type="radio" value="Strongly disagree" name="0" id="1"></div></li>

<li onclick="checkThis(this);"><div class="ui-radio"><input type="radio" value="Strongly agree" name="1" id="5"></div></li>
</ul></div></div></div>
note: Here group name alone gets changed.
Changed
<div id="ratingContainer">
to
<div class="ratingContainer"> .
Removed
onclick="checkThis(this);"
from html , added one event handler for all input elements
elems.find("input").on("change", checkThis);
Try
var allChecked = false;
var names = [];
var elems = $(".0");
function checkThis(e) {
var name = e.target.name;
if (names.length < elems.length) {
names.push(name);

allChecked = elems.get().every(function(el, i) {
return $(el).find(":checked").is("*")
});
alert(name + " checked");
if (allChecked) {
// do stuff
alert(names.join(" and ") + " checked, " + "allChecked:" + allChecked);
};
};
elems.find("input").on("change", checkThis);

Looks like you already know how to count up the checked elements. If you put that in the first loop, you can mark a variable false if any come up empty.
var names = [];
var allChecked = true;
$('input[type="radio"]').each(function() {
// Creates an array with the names of all the different checkbox group.
names[$(this).attr('name')] = true;
if $(this).filter(':checked').length === 0 {
allChecked = false;
}
});
https://jsfiddle.net/eu6L1f80/2/
Javascript:
$('form').on('submit', function(e) {
e.preventDefault();
var checkboxes = {};
$(':checkbox').each(function() {
checkboxes[$(this).attr('name')] = true;
});
$.each(checkboxes, function(i, val) {
if($(':checkbox[name='+i+']').is(':checked')) delete checkboxes[i];
});
if (!Object.keys(checkboxes).length) {
alert('success!');
} else {
alert('error!');
}
});

I am attemting to filter list items depending on whether certain checkboxes are checked or not.
I have managed to get the filtering to work but I am struggling to remove all list items on page load.
The idea is for 'list items' not to display untill the 'options' checkboxes are ckecked
I have placed my working version online here http://dev.perfectdaycanada.com/filter/
Thank you in advanced to anyone who can help me, it's much appreciated.
The javascript for filtering:
$(document).ready(function(){
$("input.type_check").attr("checked", "").click(function() {
if($(this).is(':checked')) {
$("#case-studies li."+$(this).attr('id')).removeClass('type_hidden');
$("#case-studies li").not(".type_hidden, .start_hidden").slideDown();
} else {
$("#case-studies li."+$(this).attr('id')).addClass('type_hidden');
$("#case-studies li."+$(this).attr('id')).slideUp();
}
});
$("input.start_check").attr("checked", "").click(function() {
if($(this).is(':checked')) {
$("#case-studies li."+$(this).attr('id')).removeClass('start_hidden');
$("#case-studies li").not(".type_hidden, .start_hidden").slideDown();
} else {
$("#case-studies li."+$(this).attr('id')).addClass('start_hidden');
$("#case-studies li."+$(this).attr('id')).slideUp();
}
});
});
HTML:

<li id="event_2191" class="ethics_air_emissions farms_tomatoes areas_assurance countries_austria">– Tomatoes, Portugal</li>

Just add the class type_hidden to your list items like this:
<li id="event_1768" class="other classes type_hidden">– Potatoes, Poland</li>
(and than for all list items of course)
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;
