<p>I am after documentation on using wildcard or regular expressions (not sure on the exact terminology) with a jQuery selector.</p>

<p>I have looked for this myself but have been unable to find information on the syntax and how to use it. Does anyone know where the documentation for the syntax is?</p>

<p>EDIT: The attribute filters allow you to select based on patterns of an attribute value.</p>

James Padolsey created a
wonderful filter
that allows regex to be used for selection.
Say you have the following
```
div
```
:
```
```
<div class="asdf">
```
```
Padolsey's
```
:regex
```
filter can select it like so:
```
```
$("div:regex(class, .*sd.*)")
```
```
Also, check the
official documentation on selectors
.
UPDATE:
```
:
```
syntax Deprecation JQuery 3.0
Since
```
jQuery.expr[':']
```
used in Padolsey's implementation is already deprecated and will render a syntax error in the latest version of jQuery, here is his code adapted to jQuery 3+ syntax:
```
```
jQuery.expr.pseudos.regex = jQuery.expr.createPseudo(function (expression) {
    return function (elem) {
        var matchParams = expression.split(','),
            validLabels = /^(data|css):/,
            attr = {
                method: matchParams[0].match(validLabels) ?
                    matchParams[0].split(':')[0] : 'attr',
                property: matchParams.shift().replace(validLabels, '')
            },
            regexFlags = 'ig',
            regex = new RegExp(matchParams.join('').replace(/^\s+|\s+$/g, ''), regexFlags);
        return regex.test(jQuery(elem)[attr.method](attr.property));
    }
});
```
```
