Javascript Solutions
Solution 1 - Javascript
Try:
$(document).ready(function() {
$("a").click(function(event) {
alert(event.target.id+" and "+$(event.target).attr('class'));
});
});
Solution 2 - Javascript
This will contain the full class (which may be multiple space separated classes, if the element has more than one class). In your code it will contain either "konbo" or "kinta":
event.target.className
You can use jQuery to check for classes by name:
$(event.target).hasClass('konbo');
and to add or remove them with addClass and removeClass.
Solution 3 - Javascript
You will get all the class in below array
event.target.classList
Solution 4 - Javascript
$(document).ready(function() {
$("a").click(function(event) {
var myClass = $(this).attr("class");
var myId = $(this).attr('id');
alert(myClass + " " + myId);
});
})
<html>
<head>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.7.2.min.js"></script>
</head>
<body>
<a href="#" id="kana1" class="konbo">click me 1</a>
<a href="#" id="kana2" class="kinta">click me 2</a>
</body>
</html>
This works for me. There is no event.target.class function in jQuery.
Solution 5 - Javascript
An improvement on Vishesh answer, which instead returns a Boolean:
event.target.classList.contains(className)
Solution 6 - Javascript
If you are using jQuery 1.7:
alert($(this).prop("class"));
or:
alert($(event.target).prop("class"));
Solution 7 - Javascript
Careful as target might not work with all browsers, it works well with Chrome, but I reckon Firefox (or IE/Edge, can't remember) is a bit different and uses srcElement. I usually do something like
var t = ev.srcElement || ev.target;
thus leading to
$(document).ready(function() {
$("a").click(function(ev) {
// get target depending on what API's in use
var t = ev.srcElement || ev.target;
alert(t.id+" and "+$(t).attr('class'));
});
});
Thx for the nice answers!
