How do I parse an URL with JavaScript (also with jQuery)?
比如我把这个放在我的绳子里，
url = "http://example.com/form_image_edit.php?img_id=33"
I want to get the value of img_id
I know I can do this easily with PHP with parse_url(), but I want to know how it is possible with JavaScript.
You can use a trick of creating an a-element, add the url to it, and then use its Location object.
function parseUrl( url ) {
var a = document.createElement('a');
a.href = url;
return a;
}
parseUrl('http://example.com/form_image_edit.php?img_id=33').search
它将输出:?img_id=33
你也可以用php.js来得到parse_url function in JavaScript.
如果您需要做的不仅仅是超简单的URL处理，我建议您使用卓越的URI.js库.
