Return False

Yes, I know Java <> Javascript....

anyway: I have the following function that validates a date based on the component parts sent to it.

HTML Code:

  function isValidDate(date, month, year)
  {
    var flagDate = new Date(year, month, date);
    
    if (flagDate.getFullYear() != year || flagDate.getMonth() != month || flagDate.getDate() != date)
    {
    //alert("false")
    return false;
    }
    else
    {
    //alert("true")
    return true;
    }
  }

the problem I have is: The above function is called from another function and the "return false;" & "return true;" lines do not do what I want them to...

If the above function validates to false, I want to stop the function it was called from from continuing.

Hope that makes some sort of sense?

Thanks -GeorgeV

You may return a variable and check that at your main program.
What exactly do you do? Form example.

You know what - I think I've just solved it!

I decided to set up a flag which got set to "T" or "F" which I could test on when I returned to the first function.

I had some trouble with declaring variables and setting values in and outside of the function but I think I'm there now!

Code:

    if (flagDate.getFullYear() != year || flagDate.getMonth() != month || flagDate.getDate() != date)
        {
        Test = "F"
        return Test
        }

Code:

      if (Test == "T")
      {alert("Test = T")}

thank you for your suggestion

Ahh, but I have a lovely new JS problem

Code:

  var x = document.getElementsByName("urn:schemas-microsoft-com:office:office#Training_x0020_Course")[0];
  x.onchange = TrainingCourseOnChange;  
  
  function TrainingCourseOnChange()
  {
    alert("You chose course: " + x.value)
  }

The above code applies to a drop down listbox which works...
Except x.value is the ID number of the object in the list, not the text stored next to it! (I've added a screenie for clarification).

And I want to return the Text as shown in the textbox...

Yes, I am unfortunate enough to be working with sharepoint for this problem
