Question

如何在asp.net 的updatepanel 中从后端调用javascript 函数。

Answer 1

ScriptManager.RegisterStartupScript(this,yourUpdatePanel.getType(),"Your js",true);

Answer 2

Its not hard to do, but it's depends on you, how you can call a method/function,

1) without update panel

 function welcome() { alert("Welcome Guys!"); } protected void Page_Load(object sender, EventArgs e) { ClientScript.RegisterStartupScript(Page.GetType(), "OnLoad", "welcome();", true); }

2) With update panel

 function welcome() { alert("Welcome Guys!"); } protected void Page_Load(object sender, EventArgs e) { ScriptManager.RegisterStartupScript(Page, GetType(), "JsStatus","welcome();", true); }

both are perfectly works ;)
