对于一些开发场景，不使用Jsp或freemarker及其其他的模板引擎时，通常通过切割url获得对应的参数，然后通过AJAX与后台交互得到对应的数据
下面是演示实例:
test.html
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>切割URL</title> </head> <body> <a href="/LMS/test?userId=1">点击</a> </body> </html>
test2.html
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>三级联动效果</title> <style type="text/css"> select{ width:100px; text-align:center;} </style> <script type="text/javascript"> window.onload=function(){ GetRequest(); }; function GetRequest() { var fullURL = window.location.href; alert(fullURL); var url = location.search; //获取url中"?"符后的字串 var theRequest = new Object(); alert(url); if (url.indexOf("?") != -1) { var str = url.substr(1); strs = str.split("&"); alert(strs) for(var i = 0; i < strs.length; i ++) { theRequest[strs[i].split("=")[0]]=unescape(strs[i].split("=")[1]); alert(theRequest[strs[i].split("=")[0]]); } } return theRequest; } </script> </head> <body> <p>测试:</p> </body> </html>
