Problem with alert()

mych · Feb 27, 2009

Hi I have the following code that I'm experimenting with...

Code:

<html>
<head>


<script type="text/javascript">

	function disp_mnemonic(mtxt)

	var tl= len(mtxt)
	var x = 1
	var mnem = ""

	for (x=1;x<=tl;x++)
	{

		switch (mid(mtxt,x,1)
		{
		case 'A';
			mnem = mnem+ 'A - Alfa' + '\n'
			break;
		case 'B';
			mnem = mnem+ 'B - Bravo' + '\n'
			break;
		case 'C';
			mnem = mnem+ 'C - Charley' + '\n'
			break;
		case 'D';
			mnem = mnem+ 'D - Delta' + '\n'
			break;
		case 'E';
			mnem = mnem+ 'E - Echo' + '\n'
			break;
		....
		case 'Z';
			mnem = mnem+ 'Z - Zulu' + '\n'
			break;
		}
	}
	{
	alert(mnem);
	}

</script>

</head>
<body>

<% RPwd="RS56QT" %>

<input type="button" onclick="disp_mnemonic('<%=RPwd%>')" value="Display mnemonic box" />

</body>
</html>

The error I'm getting is Object Expected and points to the line.... alert(mnem);

I can't figure out what I'm missing?

Basically I'm trying to port a function I had in vb6 to a web app.

Thanks

I've not failed! Just found 100 ways that don't work...yet!

Hi

Try harder. Seems that you not even read the JavaScript specification.

Code:

function disp_mnemonic(mtxt)
[red]{[/red]
    var tl= mtxt[red].length[/red]
    var x = 1
    var mnem = ""

    for (x=1;x<=tl;x++)
    {

        switch (mtxt[red].substr[/red](x,1)[red])[/red]
        {
        case 'A'[red]:[/red]
            mnem = mnem+ 'A - Alfa' + '\n'
            break;
        case 'B'[red]:[/red]
            mnem = mnem+ 'B - Bravo' + '\n'
            break;
        case 'C'[red]:[/red]
            mnem = mnem+ 'C - Charley' + '\n'
            break;
        case 'D'[red]:[/red]
            mnem = mnem+ 'D - Delta' + '\n'
            break;
        case 'E'[red]:[/red]
            mnem = mnem+ 'E - Echo' + '\n'
            break;
        [gray]// ....[/gray]
        case 'Z'[red]:[/red]
            mnem = mnem+ 'Z - Zulu' + '\n'
            break;
        }
    }

    alert(mnem);
[red]}[/red]

And better use another browser. Explorer's error messages are not really helpful. Personally I recommend FireFox with FireBug extension.
