Calling Javascript from an asp button

LouisC4 · Feb 6, 2007

Hello, I am trying to call a javascript from a asp button but I am not getting any results, here is my code:

Code:

<head runat="server">
    <title>Untitled Page</title>

    <script language="javascript">
        var msec=0
        var sec=0
        var min=0
        var hrr=0
        
        function start()
        {
            document.forms[0].display.value=hrr+":"+min+":"+sec
            go=setTimeout("start()",1)
            msec++
            
            if(msec==100)
                {
                    msec=0
                    sec++
                }
            if(sec==60)
                {
                    sec=0
                    min++
                }
            if(min==60)
                {
                    min=0
                    hrr++
                }
        }
    </script>  
</head>
<body>
<form id="form1" runat="server">
     <asp:Button ID="btnOK" runat="server" Text="OK" Width="50px"  />
</form>
</body>

On Page_Load I have:

Code:

    protected void Page_Load(object sender, EventArgs e)
    {
        btnOK.Attributes.Add("onClick", "return start();");
    }

What is wrong?

Thanks,

Louis

My first guess is that you are posting back the page and loosing state.

Never argue with an idiot. He'll just drag you to his level and beat you with experience!

How can you keep it from posting back?

Try adding the call to the function to the OnClientClick event of the Button.

I've tried onClientClick and it still doesn't fire my javascript.

It is strange.

It works perfectly for me in a simple test:

Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "[URL unfurl="true"]http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">[/URL]

<html xmlns="[URL unfurl="true"]http://www.w3.org/1999/xhtml"[/URL] >
<head runat="server">
    <title>Untitled Page</title>
    <script type="text/javascript">
        function test() {
            alert('hello');
        }
    </script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="test();" />
    </div>
    </form>
</body>
</html>
