亲爱的所有人，
如何从服务器端调用客户端javascript函数.
请帮忙.
我正在等待....我想从(Page_Load(object sender，EventArgs e)的服务器端调用dTime().
示例:

Dear All,
How to call a client side javascript function from server side.
Please help.
I am waiting.. ..I want to call dTime() from Server side on (Page_Load(object sender, EventArgs e).
Example:

<script language="javascript" type="text/javascript">
    function dTime() {

        var d = new Date();

        var h = d.getHours();

        var m = d.getMinutes();

        var s = d.getSeconds();



        //add a zero in front of numbers < 10



        m = checkTime(m);



        s = checkTime(s);





        document.getElementById('txt').innerHTML = h + ":" + m + ":" + s;

        t = setTimeout('dTime()', 500);

    }



    function checkTime(i) {



        if (i < 10) {

推荐答案

Page.RegisterStartupScript("page", "<script language='javascript'>dTime()</script>");

代替page.RegisterStartupScript，您也可以使用ClientScript.RegisterClientScriptBlock

如果您在aspx页面中使用更新面板，请使用

ScriptManager.RegisterClientScriptBlock
有关scriptmanager的信息，请参见此 [ ^ ]

in place of page.RegisterStartupScript you can also use ClientScript.RegisterClientScriptBlock

if you are using update panel in your aspx page then use

ScriptManager.RegisterClientScriptBlock
for scriptmanager see this[^]

<body onload="dTime()">

通过使用此功能，您还可以从客户端也在pageload上激活它

最好的

by using this you can activate it on pageload from client side also

All the Best
