Question

How can I call a JavaScript function if a string contains any of the items in an array?

Yes, I can use jQuery 🙂

Answer 1

You could use some(), a Mozilla extension which has been added to ECMAScript 5:

var haystack = 'I like eggs!';
if(['spam', 'eggs'].some(function(needle) {
    return haystack.indexOf(needle) >= 0;
})) alert('spam or eggs');
