JS獲取URL參數

使用JavaScript獲取URL上的參數值
方法一:
function getUrlParam(name) {
var reg = new RegExp(“(^|&)” + name + “=([^&]*)(&|$)”); //構造一個含有目標參數的正則表達式對象
var r = window.location.search.substr(1).match(reg); //匹配目標參數
if (r != null) return unescape(r[2]); return null; //返回參數值
}
方法二:

function GetRequest() {

var url = location.search;//獲取url中”?”符後的字串

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;

}

var Request = new Object();
Request = GetRequest();

var 參數1,參數2,參數3,參數N;

參數1 = Request[‘參數1’];

參數2 = Request[‘參數2’];

參數3 = Request[‘參數3’];

參數N = Request[‘參數N’];
