<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>

然后我們通過(guò)調(diào)用此函數(shù)獲取對(duì)應(yīng)參數(shù)值：

<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>

以此獲取url串中所帶的同名參數(shù)

二、正則分析法

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("參數(shù)名1"));
alert(GetQueryString("參數(shù)名2"));
alert(GetQueryString("參數(shù)名3"));

補(bǔ)充：js 獲取url的get傳值函數(shù)

function getvl(name) {
　　var reg = new RegExp("(^|\\?|&)"+ name +"=([^&]*)(\\s|&|$)", "i");
　　if (reg.test(location.href))
　　return unescape(RegExp.$2.replace(/\+/g, " "));
　　return "";
};

用法簡(jiǎn)單的說(shuō)一下

比如url是:http://localhost/index.php?qz=ddddk中qz的值代碼如下

復(fù)制代碼代碼如下:

getvl(bb);//這樣就可以了

希望本文所述對(duì)大家JavaScript程序設(shè)計(jì)有所幫助。
