没有从后面的代码中调用Javascript函数

Question

I have a javascript function like

function CloseWindow() {
    alert("I am firing");    // window.close();         
}

I am trying to call it from code behind button click event like

Page.ClientScript.RegisterStartupScript([GetType](), "Javascript", "javascript:CloseWindow();", True)

The function is not firing alert message. If I call the same function from OnClientClick it is firing.

OnClientClick="javascript:();"

What might be the cause? If you want anymore clarification, please let me know.

by <script type="text/javascript" language="javascript"> function CloseWindow() { alert("I am firing"); // window.close();
} function chkLength(evt, len) { var str = document.getElementById(evt.id); if (str.value.length < len) return true; else return false; } </script> <script type="text/javascript" language="javascript"> function CloseWindow() { alert("I am firing"); // window.close();
} function chkLength(evt, len) { var str = document.getElementById(evt.id); if (str.value.length < len) return true; else return false; } </script>

Answer 1

If you Used Update Panels Then You can Use:

ScriptManager.RegisterStartupScript(this, this.GetType(), Guid.NewGuid().ToString(), "javascriptFunction();", true);

Other Wise You can Use

ClientScript.RegisterStartupScript
        (GetType(),Guid.NewGuid().ToString(), "javascriptFunction();",true);

Answer 2

try the below code....

ClientScript.RegisterStartupScript
        (GetType(),Guid.NewGuid().ToString(), "javascript: CloseWindow();",true);

Answer 3

The third parameter (script) must be "CloseWindow();" and not "javascript:CloseWindow();"
