How can I reset all checkboxes in a document using jQuery or pure JS?
This question is related to
javascript
jquery
checkbox
As said in Tatu Ulmanen's answer using the follow script will do the job
$('input:checkbox').removeAttr('checked');
But, as Blakomen's comment said, after version 1.6 it's better to use jQuery.prop() instead
Note that in jQuery v1.6 and higher, you should be using .prop('checked', false) instead for greater cross-browser compatibility
$('input:checkbox').prop('checked', false);
Be careful when using jQuery.each() it may cause performance issues. (also, avoid jQuery.find() in those case. Use each instead)
$('input[type=checkbox]').each(function()
{
$(this).prop('checked', false);
});
In some cases the checkbox may be selected by default. If you want to restore default selection rather than set as unselected, compare the defaultChecked property.
$(':checkbox').each(function(i,item){
this.checked = item.defaultChecked;
});
I have used this before:
$('input[type=checkbox]').prop('checked', false);
seems that .attr and .removeAttr doesn't work for some situations.
edit: Note that in jQuery v1.6 and higher, you should be using .prop('checked', false) instead for greater cross-browser compatibility - see https://api.jquery.com/prop

to unchecked checked box, turn your logic around to do opposite
You can be selective of what div or part of your page can have checkboxes checked and which don't. I came across the scenario where I have two forms in my page and one have prefilled values(for update) and other need to be filled fresh.
$('#newFormId input[type=checkbox]').attr('checked',false);
this will make only checkboxes in form with id newFormId as unchecked.
var clist = document.getElementsByTagName("input");
for (var i = 0; i < clist.length; ++i) { clist[i].checked = false; }
$('input:checkbox').each(function() { this.checked = false; });
To do opposite, see: Select All Checkboxes By ID/Class
If you want to use form's reset feature, you'd better to use this:
$('input[type=checkbox]').prop('checked',true);
OR
$('input[type=checkbox]').prop('checked',false);
Looks like removeAttr() can not be reset by form.reset().
The above answer did not work for me -
The following worked
$('input[type=checkbox]').each(function()
{
this.checked = false;
});
This makes sure all the checkboxes are unchecked.
I used something like that
$(yourSelector).find('input:checkbox').removeAttr('checked');
