jQuery if checkbox is checked

jQuery if checkbox is checked

回答1

for jQuery 1.6 or higher:

if ($('input.checkbox_check').prop('checked')) {
    //blah blah
}

the cross-browser-compatible way to determine if a checkbox is checked is to use the property https://api.jquery.com/prop/

Note that "The .prop() method gets the property value for only the first element in the matched set." see api.jquery.com/prop
