Question

How can I find a word with regular expression in Javascript?

For example:

http://127.0.0.1/w/?id=2&tab=wow

I want to know if this link contains the word ‘tab’.

Answer 1

var string = 'http://127.0.0.1/w/?id=2&tab=wow'
var containsTab = string.indexOf('tab') > -1

Or if you really want to use a regex:

var containsTab = string.match(/tab/);
