复制代码 代码如下:
<div id="page">
<select name="select1" id="select-type">
<option value="0">请选择</option>
<option value="1">企业</option>
<option value="2">产品</option>
</select>
</div>

复制代码 代码如下:

var aPairs, aTmp;
var queryString = new String(window.location.search);

aPairs = queryString.split("&");
for (var i = 0; i < aPairs.length; i++) {

this.data[aTmp[0]] = aTmp[1];
}
},
GetValue: function (key) {
return this.data[key];
}
}

$(function () {
//初始化
QueryString.Initial();

var type = QueryString.GetValue("type");

if (typeof (type) != "undefined") {

}

$("#select-type").bind("change", function () {

//alert(row);
if (row == 1)
location.href = "?type=" + row;
if (row == 2)
