[jquery] Click toggle with jQuery

I've used a hover function where you do x on mouseover and y and mouseout. I'm trying the same for click but it doesn't seem to work:

$('.offer').click(function(){ 
  $(this).find(':checkbox').attr('checked', true ); 
},function(){
  $(this).find(':checkbox').attr('checked', false ); 
});

I want the checkbox to be checked when clicking on a div, and unchecked if clicked again - a click toggle.

In JQuery I don't think that click() accepts two functions for toggling. You should use the toggle() function for that: http://docs.jquery.com/Events/toggle

jQuery: Best Way, delegate the actions to jQuery (jQuery = jQuery).

$( "input[type='checkbox']" ).prop( "checked", function( i, val ) {
    return !val;
});

Another alternative solution to toggle checkbox value:

<div id="parent">
    <img src="" class="avatar" />
    <input type="checkbox" name="" />
</div>


$("img.avatar").click(function(){

    var op = !$(this).parent().find(':checkbox').attr('checked');
    $(this).parent().find(':checkbox').attr('checked', op);

});

Another approach would be to extended jquery like this:

$.fn.toggleCheckbox = function() {
    this.attr('checked', !this.attr('checked'));
}

Then call:

$('.offer').find(':checkbox').toggleCheckbox();

Why not in one line?

$('.offer').click(function(){
    $(this).find(':checkbox').attr('checked', !$(this).find(':checkbox').attr('checked'));
});

<label>
    <input
        type="checkbox"
        onclick="$('input[type=checkbox]').attr('checked', $(this).is(':checked'));"
    />
    Check all
</label>

Easiest solution

$('.offer').click(function(){
    var cc = $(this).attr('checked') == undefined  ? false : true;
    $(this).find(':checkbox').attr('checked',cc);
});

Warning: using attr() or prop() to change the state of a checkbox does not fire the change event in most browsers I've tested with. The checked state will change but no event bubbling. You must trigger the change event manually after setting the checked attribute. I had some other event handlers monitoring the state of checkboxes and they would work fine with direct user clicks. However, setting the checked state programmatically fails to consistently trigger the change event.

jQuery 1.6

$('.offer').bind('click', function(){ 
    var $checkbox = $(this).find(':checkbox');
    $checkbox[0].checked = !$checkbox[0].checked;
    $checkbox.trigger('change'); //<- Works in IE6 - IE9, Chrome, Firefox
});

$('.offer').click(function() { 
    $(':checkbox', this).each(function() {
        this.checked = !this.checked;
    });
});

$('.offer').click(function(){ 
    if ($(this).find(':checkbox').is(':checked'))
    {
        $(this).find(':checkbox').attr('checked', false); 
    }else{
        $(this).find(':checkbox').attr('checked', true); 
    }
});

try changing this:

$(this).find(':checkbox').attr('checked', true ); 

to this:

$(this).find(':checkbox').attr('checked', 'checked'); 

Not 100% sure if that will do it, but I seem to recall having a similar problem. Good luck!

You could use the toggle function:

$('.offer').toggle(function() {
    $(this).find(':checkbox').attr('checked', true);
}, function() {
    $(this).find(':checkbox').attr('checked', false);
});

I have a single checkbox named chkDueDate and an HTML object with a click event as follows:

$('#chkDueDate').attr('checked', !$('#chkDueDate').is(':checked'));

Clicking the HTML object (in this case a <span>) toggles the checked property of the checkbox.

    $('controlCheckBox').click(function(){
    var temp = $(this).prop('checked');
    $('controlledCheckBoxes').prop('checked', temp);
});
