jQuery Check if Element has Class Attached
Share
jQuery code snippet to check whether a web page element has a specific css class attached. Could be used to check if the element needs additional formatting or if you want to protect certain page elements. To do this we can use the jQuery hasClass() function or jQuery is() function.
$("div").click(function(){
if ( $(this).hasClass("protected") ) {
//do something it does have the protected class!
alert("i have the protected class");
}
});
OR
$("div").click(function(){
if ( $('#myDiv').is('.pretty.awesome') ) {
//do something it does have the protected class!
alert("i have the pretty and awesome classes");
}
});
Note: that this method allows you to test for other things as well. IE – Check if an element is hidden.
if ( $('#myDiv').is(':hidden') ) {
//do something I am hidden!
alert("i am hidden!");
}
