Question

I have define a custom attribute called “data-children”,use as:

<div data-children=“test01 test02 test03”></div>

But how can I judge the property has “test04”:

var $collection=$('div').attr('data-children')
……//then what can I do?

Answer 1

Since it returns a string, you can use the match method of the string object. I would suggest using the data method, though, if possible.

if ($('div').data('children').match(/(^|\s+)test04(\s+|$)/)) {
}
