hasClass doesn't work in my js code?

Question

I want to use hasClass in the following code, but that doesn\'t work for me, please see my demo in jsfiddle and tell me, what do I do wrong?

Answer 1

It is not the element that exposes the IdRelation class, but its child. Try:

if ($("span input").hasClass("IdRelation")) {
    alert("ok");
}​

Or maybe, depending on your actual markup:

if ($("span > input").hasClass("IdRelation")) {
    alert("ok");
}​

The selector in the first code snippet will match all elements that are descendants of a element, whereas the selector in the second snippet will match all elements that are direct children of a element. Both will match the element in your sample markup.
