Question

How can I find whether a keyword exists in an array which was splitted with split()?

// Get the object infomation.
var keyword = 'story';
var path = $(this).find('a').attr('href');
var array_url = path.split('/');

if(keyword == array_url) alert('match!'); // does it work like this??

The url path from a tag is something like this – www.mysite.com/story/article-1

Thanks.

EDIT:

if ($.inArray(keyword, array_url)) alert('match!');

this will alert the match whether the array has the keyword in it or not.

if(keyword == array_url) alert('match!'); // does it work like this??

Well, does it? 😉

jQuery has a convenience function for searching through arrays.

if ( $.inArray(keyword, array_url) > -1 ) alert('match!)';

Or, in your case, you could use regular JavaScript string operations:

if ( $(this).find('a').attr('href').indexOf(keyword) > -1 ) alert('match!)';
