Replace a character in an input box - onkeypress - FF problem

3 New Member

Hi,
I have the following code which works fine in IE but does not in Firefox:

Expand|Select|Wrap|Line Numbers

 <html> <head>

     <title>space-plus</title>

<script type="text/javascript">

<!--

function alpha(e) {

     if(e.keyCode==32) {return (e.keyCode=43);}

}

// -->

</script>

</head>  <body> <form>

<input type="text" onkeypress="return alpha(event);">

</form> </body> </html>

I have tried a number of variations - without success. The idea is that when a user enters a space in the input box a plus sign is shown.
Any answers? Can Firefox do this?

i believe in firefox its charCode
so you could do something like

Expand|Select|Wrap|Line Numbers

 
<html> <head>

<title>space-plus</title>

<script type="text/javascript">

<!--

function alpha(e) {

var unicode = e.charCode ? e.charCode : e.keyCode;

if (unicode==32) { return (e.charCode ? e.charCode=43 : e.keyCode=43); }

}

// -->

</script>

</head> <body> <form>

<input type="text" onkeypress="return alpha(event);">

</form> </body> </html>

Thanks Clint,
works in IE but still not in Firefox!
I wonder if the problem lies in intercepting the keycode and sending on the new keycode (or charcode). I have also tried 'onkeyup' and 'onkeydown' but these stop the function working in IE.
Your code suggestion was:

Expand|Select|Wrap|Line Numbers

 <html> <head>

<title>space-plus</title>

<script type="text/javascript">

<!--

function alpha(e) {

var unicode = e.charCode ? e.charCode : e.keyCode;

if (unicode==32) { return (e.charCode ? e.charCode=43 : e.keyCode=43); }

}

// -->

</script>

</head> <body> <form>

<input type="text" onkeypress="return alpha(event);">

</form> </body> </html>
