How to check whether a checkbox is checked in jQuery? 56 answers

尝试使用.is()函数以及:checked选择器来完成您的任务，

ckb = $("#ickb").is(':checked');

Use is() with :checked to get the result as boolean that is true if checkbox is checked.

ckb = $("#ickb").is(':checked');

Or, you can use length, if it is zero then it is not checked.

ckb = $("#ickb::checked").length
