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

            //http://localhost:19090/home/index?id=1var Source = $.url.attr ("source");//Http://localhost:19090/home/index?id=1var protocol = $.url.attr ("protocol");//HTTP all optional values HTTP, HTTPS, file, etcvar path = $.url.attr ("path");///home/indexvar host = $.url.attr ("host");//localhostvar port = $.url.attr ("port");//19090var relative = $.url.attr ("relative");///home/index?id=1var 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"); Span style= "color: #008000;" >// 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 example above are also called to handle shouting
