# Jquery

## Eigen CSS filters maken
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
$.expr[':'].external = function(elem,index,match) {
|
||
|
|
var url = elem.href || elem.src,
|
||
|
|
loc = window.location;
|
||
|
|
return !!url.match(new RegExp('^' + loc.protocol + '//' + '(?!' + loc.hostname + ')' ));
|
||
|
|
};
|
||
|
|
|
||
|
|
// You can now use it within your selectors:
|
||
|
|
|
||
|
|
// Find all external anchors:
|
||
|
|
$('a:external');
|
||
|
|
|
||
|
|
// Find all external script elements:
|
||
|
|
$('script:external');
|
||
|
|
|
||
|
|
// Determine if link is external:
|
||
|
|
$('a#mylink').is(':external'); // true/false
|
||
|
|
```
