前台js改變Session的值（用ajax）

首先，html代碼：

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

js代碼：

var compareContent=”你要改變的值";

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
