Description

The checkSubmit function in typo3/jsfunc.tbe_editor.js (used in backend forms) is in IMHO not correctly implemented.

The lines 260-264 checks if any user-defined javascript (registered with t3lib_tceforms->additionalJS_submit) should be evaluated before the form is submitted.

But it uses the eval-function to execute the javascript and this means that you cannot abort the submit in your own javascript-code (using "return false;") .

Hi,
what do you mean with "abort the submit in your own javascript-code"? Could you please give an example?
We cound integrate another check before line 266, e.g.

if (STOP) {
  return false;
}

So, you can add e.g. the following to t3lib_TCEforms->additionalJS_submit:

if (!MyValidatorObject.someFunction()) {
  STOP = true;
}

Hi,

Yes, that's exactly what I had in mind.

I want e.g. to do a check on a specific field and if it doesn't have a specific value the submit should be aborted.

Btw. I think this used to work in version 4.0 but back then the code in t3lib_TCEforms->additionalJS_submit was simply injected directly in the onsubmit function.

I guess this is more a feature than a bug... But we should definitely have it.
