calling a function

Richey · Dec 18, 2001

Hi

I have a ASP page called 'business' which has text fields etc and on the click of a button 'Submit form' it has this

Code:

<INPUT TYPE=&quot;submit&quot; NAME=&quot;butEdit&quot; VALUE=&quot;Submit Form&quot; ONCLICK=&quot;return validate();&quot; style=&quot;font-family: Arial Black; border: 3 solid #000080; padding-top: 0; padding-bottom: 2&quot;>

at the end of the form there are various functions written in Javascript such as

Code:

<!--when the user clicks the register now button it calls the method Validate --> 
<!--under are the functions called within the function 'Validate' --> 


<SCRIPT LANGUAGE=&quot;JavaScript&quot;>
<!-- Hide script from older browsers
//************************************************************************************************************
//    function to validate a number that is typed
function isDigit(c)
    {
    var test = &quot;&quot; + c;
    if (test == &quot;0&quot; || test == &quot;1&quot; || test == &quot;2&quot; || test == &quot;3&quot; || test == &quot;4&quot; 
    || test == &quot;5&quot; || test == &quot;6&quot; || test == &quot;7&quot; || test == &quot;8&quot; || test == &quot;9&quot;)
        {
        return true;
        }
    return false;
    }
//************************************************************************************************************
//		function to validate a row of numbers by calling the isDigit function numbers (K++)

However when the button is clicked no validation is performed. Any ideas?

You could try something like this...

<SCRIPT LANGUAGE="JavaScript">
// Set the background colour
function checkIt()
{
if( document.myForm.txtData.value == "&quot

{
alert("Text box cannot be blank.&quot

;
return false;
}
return true;
}

function numberChecker(event)
{
if (navigator.appName == "Microsoft Internet Explorer&quot

{
if (event.keyCode < 48 || event.keyCode > 57)
{
alert("I want only numbers." );
return false;
}
else
return true
}
else
{
if (event.which < 48 || event.which > 57)
{
alert("I want only numbers." );
return false;
}
else
return true
}

}

</SCRIPT>

</HEAD>
<BODY>
<FORM NAME="myForm" METHOD="POST" ACTION="handler.asp" onsubmit="return checkIt()">
<CENTER>
<INPUT NAME="txtData" onKeyPress="return numberChecker( event )"><BR>
<INPUT TYPE="SUBMIT" VALUE="Submit">
</CENTER>
</FORM>
