Form Validation

[brianh]

Hello All,

I have a pretty large ASP app (30 pages). On this app, there are many text boxes, etc. I would like to validate all of these, but to do individual javascript functions on each page seems silly. Logically, I would like to use an external js file and just pass all of the text boxes there for validation. BUt I am a little confused on how to implement that. Ideas?

In your .js file:

function validate(obj, message) {
	if (obj.value == "") {
		alert(message);
		obj.focus();
		return false;
	}
	return true;
}

OK, where would you call that (onBlur of the text box, or somwhere else. Here is what I have so far:

<input type="text" name="txtotherMake" size="20" maxlength="20" onBlur="validate "document.wStations.otherMake.value", "you messed up");">

I usually do the validation when they're submitting a page - it annoys the user less (the user being me - page has to be tested, don't it?)

yeah it is annoying to get a pop up message everytime you leave a text box without filling it out. The only issue is that I am already calling a function when the user submits the form, but I guess that I could place the code in that function.

Much better that way IMO - less code, less irritation (on both your & the visitors' sides), cleaner & more efficient really.
