MySQL's LIKE in JQuery

Question

I'd like to filter several SPANs with the text they contain:

$('spanFilter').filter(function(){
    var html = $(this).html();
    return //comparison html LIKE %asdf%
});

In the comparison, I'm trying to do something like MySQL's LIKE:

field LIKE %asdf%

How can I achieve that?

Answer 1

Not sure exactly what it is you're after but you can use the :contains() selector. For example:

$('spanFilter').filter(function(){
    var html = $(this).html();
    $("span:contains(asdf)", this).addClass('highlight");
});

Answer 2

field LIKE %asdf%

can work like

$("span:contains('asdf')")

:contains(text) - Matches elements which contain the given text.

Answer 3

There are many ways to do this:

1. Simple: using indexOf

   return html.indexOf('asdf') >= 0;

2. Complex: use RegExp

   return /asdf/.test(html);

Note that RegExp are more powerful and can match different texts. Here's a guide about them.
