multiple functions for a field

Copy linkTweet thisAlerts:
Jun 03.2004

Hey all, I’m sure this is an easy one, but how would i nest multiple functions for an onChange event for a form field?

Here is the field:

<input name=”Amount” type=”text” id=”Amount” size=”15″ maxlength=”15″ onchange=”if (isNotEmpty(this))/>

Here are additional functions I need to perform:

(this.value = parseFloat(this.value).toFixed(2))

and

(isNumber(this))

and

(isLan6(this))

So is there a way I can have this one field use all these validations?

Thanks all!

@BhanuJun 03.2004 — call functions in one function

like

function MainFunction(Val){

a = isNotEmpty(Val);

a = isNotEmpty(Val);

a = isLan6(this);

}

<input name="Amount" type="text" id="Amount" size="15" maxlength="15" onchange="MainFunction(this)">

@SuperfrappeauthorJun 03.2004 — Bhanu, thanks for your reply. I tried out your code exactly as you posted it, and it gives me an error. Also, how would I incorporate this:


[COLOR=blue](this.value = parseFloat(this.value).toFixed(2))[/COLOR]


Here's the line that causes the error (in red below):


[COLOR=blue]// calls multiple functions for the amount field

function MainFunction(Val){

a = isNotEmpty(Val);

a = isNumber(Val);

[COLOR=darkred]a = isLan6(this);[/COLOR]

}[/COLOR]


...and here's the line I use:


[COLOR=blue]<input name="Amount" type="text" id="Amount" size="15" maxlength="15" onchange="MainFunction(this)" />[/color]


Thanks again for any help!

a = isLan6(this); to a = isLan6(Val);

@SuperfrappeauthorJun 03.2004 — Thanks Bhanu, that worked. ALthough, I still need to work:


[color=blue]this.value = parseFloat(this.value).toFixed(2)[/color]


into the picture. This is very important to make the amount appear as money.

Thanks!
