js接受url参数
1.正則表達(dá)式
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;
}
使用方法：
alert(GetQueryString("參數(shù)名1"));alert(GetQueryString("參數(shù)名2"));
alert(GetQueryString("參數(shù)名3"));2.自定義解析
<Script language="javascript">
function GetRequest() {var url = location.search; //獲取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>
使用方法：
<Script language="javascript">
var Request = new Object();
Request = GetRequest();
var 參數(shù)1,參數(shù)2,參數(shù)3,參數(shù)N;
參數(shù)1 = Request['參數(shù)1'];
參數(shù)2 = Request['參數(shù)2'];
參數(shù)3 = Request['參數(shù)3'];
參數(shù)N = Request['參數(shù)N'];
</Script>
