I am trying to create a filter using checkboxes. I need to only have one checkbox checked at a time. How do I do this?
Scenario: The page has a catalog of watches. The user wants to filter the watches according to for men or for women
Here is my code:
$("#filter-options :checkbox").click(function()
{
$(".collection-wrapper .strap-wrapper").hide();
$("#filter-options :checkbox:checked").each(function()
{
$("." + $(this).val()).fadeIn();
});
if($('#filter-options :checkbox').filter(':checked').length < 1)
{
$(".collection-wrapper .strap-wrapper").fadeIn();
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<h3>Filter Items</h3>
<ul id="filter-options">
<li><input type="checkbox" value="filter_man" data-filter_id="man"> Man</li>
<li><input type="checkbox" value="filter_woman" data-filter_id="woman"> Woman</li>
</ul>
<div class="collection-wrapper">
<div class="strap-wrapper filter_man">
<h2>man</h2>
<p></p>
</div>
<div class="strap-wrapper filter_woman">
<h2>woman</h2>
<p></p>
</div>
<div class="strap-wrapper filter_man filter_woman">
<h2>man / woman</h2>
<p></p>
</div>
<div class="strap-wrapper filter_woman">
<h2>woman</h2>
<p></p>
</div>
</div>
Thanks in advance!
Checkboxes are used for selecting multiple values of choices. What you need is Radio Buttons. They are used exactly for this purpose. One can select only one radio button at a time. So replace your code with:
<ul id="filter-options">
<li><input type="radio" name="filter" value="filter_man" data-filter_id="man"> Man</li>
<li><input type="radio" name="filter" value="filter_woman" data-filter_id="woman"> Woman</li>
</ul>
See an example here: http://www.w3schools.com/tags/tryit.asp?filename=tryhtml5_input_type_radio
Radio buttons are what you are looking for ;)
take at look at these links:
jQuery api demo
Fiddle example
HTML:
<form id="myForm">
<input type="radio" name="myRadio" value="1" /> 1 <br />
<input type="radio" name="myRadio" value="2" /> 2 <br />
<input type="radio" name="myRadio" value="3" /> 3 <br />
</form>
JS
$('#myForm input').on('change', function() {
alert($('input[name="myRadio"]:checked', '#myForm').val());
});
You could use radio buttons or you could do something like:
$('input[type=checkbox]').change(function(){
if ($('input[type=checkbox]:checked').length > 1) {
this.checked = false;
}
})
You could just use radio buttons, but if you want to do it with checkboxes, solution is pretty simple.
When you click on one of the checkboxes, select all the checkboxes and remove "checked" state, and then just add checked on clicked checkbox
Something like this:
// On checkbox click
$("#filter-options input[type=checkbox]").click(function(event) {
// Uncheck all checkboxes
$("#filter-options input[type=checkbox]").prop("checked", false);
// Check that one that you clicked
$(this).prop("checked", true)
});

I have the three input checkboxes all of them have the same name attribute I want one of them is checked then others uncheck and disabled. I want to the jquery code within the function call on function and on change event like this code below or any another way work correctly.
<div class="topmenuitems">
<input type="checkbox" name="menu-item-topitemtypes" value="itemwithouticon" />
<input type="checkbox" name="menu-item-topitemtypes" value="itemwithicon" />
<input type="checkbox" name="menu-item-topitemtypes" value="itemicon" />
</div>
var itemWithIconCheckbox = $('.topmenitems input');
var topItemTypesFunc = function() {
//Jquery code here
};
topItemTypesFunc();
topItemTypeCheckboxes.on( 'change', topItemTypesFunc);
You can do the function you want via radio buttons. Here, I have implemented a simple logic here. When a checkbox is changed ten uncheck checkbox other then the clicked one. Here is an working example.
$('input[name="menu-item-topitemtypes"]').on( 'change', function(){
if($(this).prop('checked')){
$('input[name="menu-item-topitemtypes"]').not($(this)).prop('checked', false);
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="topmenuitems">
<input type="checkbox" name="menu-item-topitemtypes" value="itemwithouticon" />
<input type="checkbox" name="menu-item-topitemtypes" value="itemwithicon" />
<input type="checkbox" name="menu-item-topitemtypes" value="itemicon" />
</div>
This may help full to you
$('input[type="checkbox"]').on('change', function(){
if($(this).is(':checked')){
$(this).siblings().attr('disabled', 'true');
}else{
$(this).siblings().removeAttr('disabled', 'false');
}
})
How can I find which radio button is selected after a precise div?
This is an Example:
<div class="largelines">
<p class="line">OPTION 1</p>
<div class="delete">
</div>
<fieldset>
<input type="radio" id="option1" name="option1" value="option1"><label for="option1">option1 </label><br>
<input type="radio" id="option2" name="option2" value="option2"><label for="option2">option2 </label>
</fieldset>
</div>
Here, when I click on the class .delete I would like to check (with jQuery) if one of the radio button below (inside the fieldset) has been selected. Do you have any hints?
Thanks in advance.
If there is just bunch of radio button you would like to check are checked or not you can do something like this
$(document).ready(function(){
$('.delete').on('click', function(){
$(document).find('input[type=radio]').each(function(){
if($(this).get(0).checked){
//do something
}
});
});
});
Ofc in line 3 you can specify more about the radio button location. For exp $(document).find('.largelines input[type=radio]') "OR" if you need to find radio butons based on delete button you can modify the code like this:
$(document).ready(function(){
$('.delete').on('click', function(){
var $parent = $(this).parents('.largelines');
$parent.find('input[type=radio]').each(function(){
if($(this).get(0).checked){
//do something
}
});
});
});
There is bunch of other ways to do that, another one is using next() or siblings() function:
$(document).ready(function(){
$('.delete').on('click', function(){
var $fieldset= $(this).next('fieldset');
//var $fieldset= $(this).siblings('fieldset');// i comment this out [its alternative way]
$fieldset.find('input[type=radio]').each(function(){
if($(this).get(0).checked){
//do something
}
});
});
});
This find only checked radio under .largelines scope of clicked .delete element.
$(function () {
$(document).on('click', '.delete', function () {
var isChecked = $('input:radio:checked', $(this).parent()).length > 0
alert(isChecked)
})
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="largelines">
<p class="line">OPTION 1</p>
<div class="delete">
Check 1
</div>
<fieldset>
<input type="radio" id="option1" name="option1" value="option1"><label for="option1">option1 </label><br>
<input type="radio" id="option2" name="option2" value="option2"><label for="option2">option2 </label>
</fieldset>
</div>
<hr>
<div class="largelines">
<p class="line">OPTION 2</p>
<div class="delete">
Check 2
</div>
<fieldset>
<input type="radio" id="option21" name="option1" value="option1"><label for="option1">option1 </label><br>
<input type="radio" id="option22" name="option2" value="option2"><label for="option2">option2 </label>
</fieldset>
</div>
<div class="parent">
<div class="click"></div>
<div class="subdiv">
<input value="1">
<input value="2">
</div>
</div>
I have the following code, and onclick event on click div. Now I want to iterate over all inputs in this specific parent div (there are many).
So I wrote something like this:
$(this).parent().children('.subdiv input').not(':checked').length
It should output something like 1, or 2, depending of how many inputs are unchecked. But it always shows 0.
Why is that so?
Also, how can I check/uncheck them all?
$(this).parent().find('.subdiv input').not(':checked').each(function() {
// $(this) is undefined, or shows 0
});
First of all you should declare those inputs as checkboxes:
<input type="checkbox" value="1" />
Then, on click of .parent element:
$('.parent').on('click', function() {
// alert the number of checked checkboxes
alert($(this).find('input[type="checkbox"]:checked').length);
});
In order to check a checkbox, use prop() function:
$('input[type="checkbox"]').prop('checked', true); // sets input to checked state
In order to get the value of a checkbox:
var value = $('input[type="checkbox"]').val();
DEMO
$('.parent').on('click', function() {
var n = $(this).find('input[type=checkbox]:checked').length;
alert('There are ' + n + ' checked checkboxes');
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="parent">
<div class="click"></div>
<div class="subdiv">
<input type="checkbox" value="1">
<input type="checkbox" value="2" checked>
</div>
</div>
ASsuming all the inputs are checkbox or anything that can be checked
Use the below
1>No of inputs checked
$(this).parent().find('input:checked').length
1>No of inputs unchecked
$(this).parent().find('input').not(':checked').length
By default inputs will be text. And checked property does not work with text fields. It should be checkbox or radio. Try with -
<div class="subdiv">
<input type="checkbox" value="1">
<input type="checkbox" value="2">
</div>
Input text do not have checked/unchecked property. You need to define type as checkbox for input elements:
<input type="checkbox" value="1">
<input type="checkbox" value="2">
also you can narrown down the selector to get unchecked checkboxes to:
$(this).parent().find('input:not(:checked)').each(function() {
// $(this) is undefined, or shows 0
});
I have a list of checkboxes like so:
<div class="checkbox-list">
<label><input type="checkbox" value="" /> All items</label><br />
<label><input type="checkbox" value="1" /> First item</label><br />
<label><input type="checkbox" value="2" /> Second item</label><br />
<label><input type="checkbox" value="3" /> Third item</label><br />
<label><input type="checkbox" value="4" /> Forth Checkbox</label>
</div>
The behavior I am looking for is if I select the first checkbox in this div (.checkbox-list input[type=checkbox]:first) all other checkboxes after is checked off. Likewise if I select any other than the first, the first one is deselected.
I am struggling on how to check if the first one is clicked on?
$(".checkbox-list").on("change", "input[type=checkbox]", function () {
if ($(this).first()) { // <- not working - how do I know if I clicked the first one?
$("input[type=checkbox]:checked", ".checkbox-list").not(this).prop("checked", false);
$(this).prop("checked", true);
} else {
// Uncheck first checkbox
}
});
Here is a fiddle if you wish to play around: http://jsfiddle.net/4c7aubqL/1/
jsBin demo
$(".checkbox-list").on("change", ":checkbox", function() {
var $all = $(".checkbox-list").find(":checkbox");
var $first = $all.eq(0);
if ($first.is(":checked")) {
$all.not(this).prop("checked", false);
}
});
You should be using radio buttons, not checkboxes. That will do exactly what you want, with no additional effort on your part. Even if you succeed in what you are trying to do, the user interface will look wrong.
<script type="text/javascript">
(function () {
var ButtonGroup = YAHOO.widget.ButtonGroup;
var onCheckedButtonChange = function (p_oEvent) {
};
YAHOO.util.Event.onContentReady("mediaFilterButtonsFieldset", function () {
var oButtonGroup = new ButtonGroup("mediaFilterButtons");
oButtonGroup.on("checkedButtonChange", onCheckedButtonChange);
});
}());
</script>
<div id="resultInfo">
<form id="button-example-form" name="button-example-form" method="post">
<fieldset id="mediaFilterButtonsFieldset">
<div id="mediaFilterButtons" class="yui-buttongroup ie7filter" style="z-index:11;">
<div id="mediaFilterLabel">Go to</div>
<input id="radio1" class="filter_but" type="radio" name="0" value="First" checked rel="0" >
<input id="radio2" class="filter_but" type="radio" name="2" value="Second" rel="2">
<input id="radio3" class="filter_but" type="radio" name="1" value="Third" rel="1">

</fieldset>
</form>
</div>
These are my YUI buttons. They're just 3 radio buttons turned into "buttons"--literally. My question is this:
After people click the third button, I cannot manually check the first button anymore. How can I manually check "radio1"?
Edit:
According to the official YUI website, there is a method called "set". But I don't know how to use that in this buttonGroup.
The radio buttons must all have the same name attribute in order for them to be grouped together.
Answering your question with the set method. Perhaps this does the trick:
YAHOO.one("#radio1").set("checked",true);
To manually check the radio buttons, it's necessary to have the same name of radio button. Put the same name of radio button and get your result.
