Hey all,

I have an HTML form that has the submit button of course, but I need help knowing what little bit of Js code I would need to check to see if the user selected something from a set of comboboxes before submission. Has anyone here done this before and willing to share your code snippet with me.

Thanks in advance!

WF does basic value validation. It mainly just looks that a value was inputted. Anything beyond that you have to right your own JS function. There isn't anything "Standard" that I would be able to share. You will basically have to build your own. I would start by understanding the document.getElementById() function ( http://www.w3schools.com/jsref...c_getelementbyid.asp ) and go from there. You might want to look into getting some training in the basics of JS if you've never written in JS before. Or as always google is your friend and w3schools.com has a lot of good tutorials for understanding JS. There are a lot of message boards out there that deal specifically with JS. Those will probably be able to help you more then focal point depending on how complex you are looking to get. Where as many of us do know JS, remember that most people here probably learned WF first and JS second...

Eric,

Thanks for you attempt to help me. I actually already knew all that for the most part. If WF does basic validation for components, how is that done? I've seen the option within the component properties of like an input text box, but for a submit button, the only way to validate that I could see was to create an onclick event handler. I've had mixed results with that, so I was wondering if someone here that has done this a bunch could just give me a quick snippet that has worked for them. Thanks though.

CoolGuy,

WF's basic validation relies on the "required" attribute under the properties of an input. If an input is required, WF will prevent you from running the report if its empty and will highlight it with a red outline. Thats all that WF does. As much as I've tried to get IBI to tell me what function controls this, they won't provide that information. So you can't edit the function or call it on your own outside of the onExecute() call.

What is the most common thing for people to do when writing their own validation is to replace the OnSubmit function of the submit button with whatever function you are running for validation. Just remember to include the OnExecute() call that is already included in the onSubmit button.

If you have already tried something and its not working as it is expected. Maybe you would be better served to provide your code and the issues you are experiencing. It's very difficult to offer guidance on such a vague question.

Eric.Woerle,

Thanks for your insights on the required attribute that WF uses. I haven't went back to touch this issue for a bit due to having to move on to other things for the time being. I've opened a case a while ago in regards to the Selection & Validation property that allows WF to validate an input field on your form. In AppStudio 8.1.04 at least, it malfunctions. I set it to required/validate or another option/value, but it never saves it after I select it. Haven't heard back from IBI yet. Again, thanks for your time and help.
