js method to get the value passed by url_javascript skills
本文实例讲述了js获取url传值的方法。分享给大家供大家参考,具体如下:
js获取url参数值:
index.htm?参数1=数值1&参数2=数值2&参数3=数据3&参数4=数值4&......
静态html文件js读取url参数 根据获取html的参数值控制html页面输出
一、字符串分割分析法
这里是一个获取URL带QUESTRING参数的JAVASCRIPT客户端解决方案,相当于asp的request.querystring,PHP的$_GET
函数:
<Script language="javascript"> function GetRequest() { var url = location.search; //获取url中"?"符后的字串 var theRequest = new Object(); if (url.indexOf("?") != -1) { var str = url.substr(1); strs = str.split("&"); for(var i = 0; i < strs.length; i ++) { theRequest[strs[i].split("=")[0]]=unescape(strs[i].split("=")[1]); } } return theRequest; } </Script>
然后我们通过调用此函数获取对应参数值:
<Script language="javascript"> var Request = new Object(); Request = GetRequest(); var 参数1,参数2,参数3,参数N; 参数1 = Request['参数1']; 参数2 = Request['参数2']; 参数3 = Request['参数3']; 参数N = Request['参数N']; </Script>
以此获取url串中所带的同名参数
二、正则分析法
function GetQueryString(name) { var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)","i"); var r = window.location.search.substr(1).match(reg); if (r!=null) return unescape(r[2]); return null; } alert(GetQueryString("参数名1")); alert(GetQueryString("参数名2")); alert(GetQueryString("参数名3"));
补充:js 获取url的get传值函数
function getvl(name) { var reg = new RegExp("(^|\\?|&)"+ name +"=([^&]*)(\\s|&|$)", "i"); if (reg.test(location.href)) return unescape(RegExp.$2.replace(/\+/g, " ")); return ""; };
用法简单的说一下
比如url是:http://localhost/index.php?qz=ddddk中qz的值代码如下
希望本文所述对大家JavaScript程序设计有所帮助。
