JS获取URL地址栏中的参数

<script type="text/javascript">

$(function () {

var url_arr = GetURLRequest(window.location.href).split('|'); //获取当前页REQUEST集合，并存入数组。

alert(url_arr);

});

function GetURLRequest(Url) {

var u, g, StrBack = '', RETURNVALUE = "";

if (arguments[arguments.length - 1] == "#") { u = Url.split("#"); } else { u = Url.split("?"); }

if (u.length == 1) g = ''; else g = u[1];

if (g != '') {

gg = g.split("&");

var MaxI = gg.length;

str = arguments[0] + "=";

for (xm = 0; xm < MaxI; xm++) {

if (gg[xm].indexOf(str) == 0) {

StrBack = gg[xm].replace(str, "");

break;

}

RETURNVALUE += gg[xm].substring(gg[xm].indexOf('=') + 1) + "|";

}

}

return RETURNVALUE.substring(0, RETURNVALUE.length - 1);

}

</script>
