I've rendered an Django form field with CheckboxSelectMultiple widget in my page, now, on page load, I want to hide all unchecked checkbox option. I manage to hide the checkbox but I don't know how to hide the label associated with the checkbox. my question is, how can I hide this label as well? below is my code :
model.py
class model_A(models.Model):
user = models.ManyToManyField(User, blank=True)
form.py :
class EditForm(forms.ModelForm):
prefix = 'edit_form'
class Meta:
model = model_A
fields = '__all__'
widgets = {'user':forms.CheckboxSelectMultiple}
html :
<div class="field">
{{form.user}}
</div>
javascript :
$('input[type=checkbox]:not(:checked)').hide();
On view page source in browser :
<ul id="id_settings-user">
<li><label for="id_settings-user_1"><input type="checkbox" name="settings-user" value="1" id="id_settings-user_1" style="display: none;">
Person A</label>
</li>
<li><label for="id_settings-user_2"><input type="checkbox" name="settings-user" value="2" id="id_settings-user_2" style="display: none;">
Person B</label>
</li>
<li><label for="id_settings-user_3"><input type="checkbox" name="settings-user" value="3" id="id_settings-user_3" style="display: none;">
Person C</label>
</li>
</ul>
You can use .parent()/.closest() to target label then hide.
$('input[type=checkbox]:not(:checked)').parent().hide();
$('input[type=checkbox]:not(:checked)').closest('label').hide();
$('input[type=checkbox]:not(:checked)').parent().hide();
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul id="id_settings-user">
<li><label for="id_settings-user_1"><input type="checkbox" name="settings-user" value="1" id="id_settings-user_1" checked >
Person A</label>
</li>
<li><label for="id_settings-user_2"><input type="checkbox" name="settings-user" value="2" id="id_settings-user_2" >
Person B</label>
</li>
<li><label for="id_settings-user_3"><input type="checkbox" name="settings-user" value="3" id="id_settings-user_3">
Person C</label>
</li>
</ul>

I am able to create set of checkboxes and toggle between them like radio button. But When I click on a different set, the previous set checked option gets disabled. Can anyone guide where I am going wrong. Thank you.
//set1
<li class="dropdown-item">
<input type="checkbox" id="InchMm" data-id=0>
<label for="unit1">Inch</label>
</li>
<li class="dropdown-item">
<input type="checkbox" id="InchMm" data-id=1 checked>
<label for="unit2">Mm/label>
</li>
<hr/>
//set2
<li class="dropdown-item">
<input type="checkbox" id="Temp" data-id=2>
<label for="unit3">Fh</label>
</li>
<li class="dropdown-item">
<input type="checkbox" id="Temp" data-id=3 checked>
<label for="unit4">Cl</label>
</li>
Changed id for class, ids are unique, you can't have multiple elements with the same id so you can use class instead if you want to target multiple elements
ID
The id global attribute defines an identifier (ID) which must be unique in the whole document. Its purpose is to identify the element when linking (using a fragment identifier), scripting, or styling (with CSS).
<li class="dropdown-item">
<input type="checkbox" class="InchMm" data-id=0>
<label for="unit1">Inch</label>
</li>
<li class="dropdown-item">
<input type="checkbox" class="InchMm" data-id=1 checked>
<label for="unit2">Mm</label>
</li>
<hr/>
<li class="dropdown-item">
<input type="checkbox" class="Temperature" data-id=2>
<label for="unit3">Farenhiet</label>
</li>
<li class="dropdown-item">
<input type="checkbox" class="Temperature" data-id=3 checked>
<label for="unit4">Celsuis</label>
</li>
Now you can use separate onchange for each set of checkboxes
// Inch to Mm
$(".InchMm").change(function(){
$(".InchMm").prop('checked',false);
$(this).prop('checked',true);
});
//Farenhiet to celsius
$(".Temperature").change(function(){
$(".Temperature").prop('checked',false);
$(this).prop('checked',true);
});
this is my default HTML-Markup from the Wordpress-Plugin:
<ul class="gfield_checkbox" id="input_2_21">
<li class="gchoice_2_21_1">
<input name="input_21.1" type="checkbox" value="Option One" id="choice_2_21_1">
<label for="choice_2_21_1" id="label_2_21_1">Option One</label>
</li>
<li class="gchoice_2_21_2">
<input name="input_21.2" type="checkbox" value="Option Two" id="choice_2_21_2">
<label for="choice_2_21_2" id="label_2_21_2">Option Two</label>
</li>
</ul>
After the document is ready I want to change the HTML-Markup to this:
<ul class="gfield_checkbox" id="input_2_21">
<li class="gchoice_2_21_1 checkbox checkbox-styled">
<label for="choice_2_21_1" id="label_2_21_1">
<input name="input_21.1" type="checkbox" value="Option One" id="choice_2_21_1">
<span>Option One</span>
</label>
</li>
<li class="gchoice_2_21_2 checkbox checkbox-styled">
<label for="choice_2_21_2" id="label_2_21_2">
<input name="input_21.2" type="checkbox" value="Option Two" id="choice_2_21_2">
<span>Option Two</span>
</label>
</li>
</ul>
Thats what I actually did:
$('.gfield_checkbox > li').addClass('checkbox checkbox-styled');
But how do I change the other parts of the code?
To change the html, there is a few ways to do it. One way is to wrap the text inside with the span, and than select the sibling and add it inside of the label.
$("li")
.addClass("checkbox checkbox-styled")
.find("label")
.wrapInner("<span/>")
.each(function(){
label = $(this)
label.prepend(label.prev())
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<ul class="gfield_checkbox" id="input_2_21">
<li class="gchoice_2_21_1">
<input name="input_21.1" type="checkbox" value="Option One" id="choice_2_21_1">
<label for="choice_2_21_1" id="label_2_21_1">Option One</label>
</li>
<li class="gchoice_2_21_2">
<input name="input_21.2" type="checkbox" value="Option Two" id="choice_2_21_2">
<label for="choice_2_21_2" id="label_2_21_2">Option Two</label>
</li>
</ul>

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);
});

</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 two UL lists with some radio buttons. Now I want to get last selected radio button ID attribute form their UL.
For example:
If I selected radio button from first UL then return selected radio ID.
If I selected radio button from second UL then return seledted radio ID.
I have tried bellow code but not working properly. If you try with selecting first radio button from first UL you will get alert with selected ID, but when you selected radio button from second UL you will get alert from first UL and that I dont want. :(
I want to get last checked radio button ID from that UL.
Any idea how to do this?
Can you please check with this way:
First select 20 from first UL you will get 20.
Second select 80 from second UL you will get 80.
Now again change radio button from first UL and that changed radio ID I want.
Here is my JSFiddle.
Thanks.
$("#update_cart").click(function() {
var radioID = $("input[type='radio']:checked").attr("id");
if (radioID) {
alert(radioID);

Working Demo
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

{
var home= $('input:radio[name=home-location]:checked').val();
document.getElementById("h1").innerHTML=home;
var preferred= $('input:radio[name=home-preferred]:checked').val();
