ASP.net中aspx與cs函數的互調

轉載自：http://www.2cto.com/kf/201209/152898.html

aspx前台的script函數，調用aspx.cs中后台函數：

aspx：

<script type="text/javascript">
    function FrontFunction()
    {
        var RetStr=<%=BehindtFunction()%>;
        alert(RetStr);  
    }  
</script>

aspx.cs：

protected string BehindtFunction(object sender, EventArgs e)
{
    //todo:執行代碼
    return "";//需要有返回值
}

aspx.cs中后台函數，調用aspx前台的script函數：

aspx.cs：

protected string BehindtFunction(object sender, EventArgs e)
{
    //代碼
    ClientScript.RegisterStartupScript(this.GetType(), "clear", "<script>FrontFunction()</script>");
    return "";
}

aspx：

<script type="text/javascript">
    function FrontFunction()
    {
        mask.style.visibility = 'visible';
        Div2.style.visibility = 'visible';
    }   return false;
</script>
