jQuery if found in string

Question

How can I have jQuery check to see if the content of a variable contains a specific word and have it execute an alert if matched?

Answer 1

if( str.indexOf( "your word" ) !== -1 )

or

if( str.search( /your regex/ig ) )

or

if( str.match( /your regex/ig ).length > 0 )

As it shows, you do not need jQuery to solve this problem.

But, hell, why not use jQuery selectors if you want:

$('#someId:contains(text)')
