前台js改变Session的值(用ajax实现)

复制代码 代码如下:

<div style="display:none;"><iframe id="compareIframe" src=""></iframe></div>

复制代码 代码如下:

var compareContent=”你要改变的值";
if (compareContent != "") {
document.getElementById("compareIframe").src = "ajax/changeSession.aspx?compareInfo=" +compareContent;
}
ajax:
changeSession.aspx.cs
protected void Page_Load(object sender, EventArgs e)
{
Session["compare"] = Request.QueryString["compareInfo"];
}
//end
