Topic: Validating Form Data via JavaScript (Page 1 of 1)

The latest request from my higher-ups is as follows:

We have a few order forms on the website, but when a field is left blank and the Submit button is hit, all the fields are sent to our salespeople who get rather confused/frustrated/inconvenienced by all the extraneous data. They would like the forms to leave out empty fields once they're submitted.

Can this be achieved with JavaScript?

Yes it can be done in JS but it's more a server side task.
In JS you could use DOM methods to remove the empty FORM elements onSubmit. Dirty but it'll work ... if the user hasn't disabled JS.

I would consider this a task for the receiving server side page. The data collecting back end should always do validation of received data.

Indeed, liorean is right.

Javascript checks are an added bonus for usability - they are never something you should rely on.

Just to make it crystal clear. I do NOT advice to do that in JavaScript. As I said, although it's possible to do on client side, this is clearly something that is best done on server side.

This should be a one line fix on your current server side script.
