JQuery Get URL Information

jquery has a lot of ways to get URL information, but using this plugin is pretty cool.

Managed address in: Http://github.com/allmarkedup/jQuery-URL-Parser

            http://localhost:19090/home/index?id=1 var Source = $.url.attr ("source");      http://localhost:19090/home/index?id=1 var protocol = $.url.attr ("protocol");          HTTP all optional values HTTP, HTTPS, file, etc var path = $.url.attr ("path");          /home/index var host = $.url.attr ("host");          localhost var port = $.url.attr ("port");  19090 var relative = $.url.attr ("relative"); /home/index?id=1 var directory = $.url.attr ("directory");///home/index//http://          localhost:19090/floder/index.html?id=1 var file = $.url.attr ("file");        index.html var query = $.url.attr ("query");             ID = 1 This can also be called. Param () var id = $.url.param ("id");            1;        var segment = $.url.segment (1);             0:floder 1:index.html//You can also specify a different URL var seturlanchor = $.url.seturl ("http://www.baidu.com/#logo"). attr ("anchor"); At this point Seturlanchor and $.url of the above example also call the processing shout out
