$('#element').is(':checked')) The is() method is a general method that can be used for many purposes - and returns a true / false based on the comparison criteria. The :checked selector was specifically made for checking whether radio button or checkbox element have been selected or not.
prop() and is() method are the two way by which we can check whether a checkbox is checked in jQuery or not. prop(): This method provides an simple way to track down the status of checkboxes. It works well in every condition because every checkbox has checked property which specifies its checked or unchecked status.
$('button'). on('click',function() { if(! $(". first").is(":checked") && !$(
type == 'checkbox' && inputs[x]. name == 'us') { is_checked = inputs[x]. checked; if(is_checked) break; } } // is_checked will be boolean 'true' if any are checked at this point.
You can use something like this
if ($("#formID input:checkbox:checked").length > 0)
{
// any one is checked
}
else
{
// none is checked
}
JQuery .is will test all specified elements and return true if at least one of them matches selector:
if ($(":checkbox[name='choices']", form).is(":checked"))
{
// one or more checked
}
else
{
// nothing checked
}
Without using 'length' you can do it like this:
if ($('input[type=checkbox]').is(":checked")) {
//any one is checked
}
else {
//none is checked
}
You can do this:
if ($('#form_id :checkbox:checked').length > 0){
// one or more checkboxes are checked
}
else{
// no checkboxes are checked
}
Where:
:checkbox filter selector selects all checkbox.:checked will select checked checkboxeslength will give the number of checked ones thereThis is what I used for checking if any checkboxes in a list of checkboxes had changed:
$('input[type="checkbox"]').change(function(){
var itemName = $('select option:selected').text();
//Do something.
});
