js 获取url参数
在网上找到了两个很又简单实用的方法,mark下
方法一:正则分析法
function getQueryString(name) {
var reg =new RegExp("(^|&)"+ name +"=([^&]*)(&|$)", "i");
var r = window.location.search.substr(1).match(reg);
if (r !=null) return unescape(r[2]); returnnull;
}
var reg =new RegExp("(^|&)"+ name +"=([^&]*)(&|$)", "i");
var r = window.location.search.substr(1).match(reg);
if (r !=null) return unescape(r[2]); returnnull;
}
这样调用:
alert(GetQueryString("参数名1"));
alert(GetQueryString("参数名2"));
alert(GetQueryString("参数名3"));
alert(GetQueryString("参数名2"));
alert(GetQueryString("参数名3"));
方法二:
<span style= "font-size: 16px;" ><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></span> |
这样调用:
<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>
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>
