Form data won't transfer to next screen

wjenkins · September 7th, 2003, 11:10 AM

Hi;
I've got a form which has a LOT of data associated with it and some of the entries have javascript attached to drop down boxes (for selecting quantities). When the javascript executes, it puts data back into the form and all is well. Until I click to go to the next screen. No data gets transferred!
Before I added the javascript, the data would transfer just fine.
I believe there are several problems and I need some help finding a solution.
I have the following: (simplified)

<form name=menuform method=post action=NextPage>
... other data that needs to be xferred based on user selections ....
<form name=form>
<select name=sellist onChange=openxwin($i,form.sellist.options[selectedIndex].value);>
</form>
<input type="submit" name="Submit">
</form>

I have worked on this for quite a while and have discovered the following:
1) Trying to get the form.sellist.options[selectedIndex].value to work without the <form> </form> tags doesn't work at all
2) Trying to get it to work with an array of sellist doesn't work at all
3) If I could get sellist[i].options[selectedIndex].value in the openxwin JavaScript call, I might be able to get it to work and not have to deal with passing the value in the call (which necessitates the <form></form> tags, rendering the form useless).

Help please!

Hi there,

The first thing I noticed is that your form tags are nested. Your browser will be confused when you have something like this:

Code:

<form name="frm1">
  <form name="frm2">
    .... Some stuff here
  </form>
</form>

You'll need to change it to this, if it is really necessary to have two forms:

Code:

<form name="frm1">
  .... Some stuff here
</form>
<form name="frm2">
  .... Some stuff here
</form>

I also recommend using quotes for attribute values as they prevent subtle bugs in your code. So change:

Code:

<form name=menuform method=post action=NextPage>

to

Code:

<form name="menuform" method="post" action="NextPage">

This isn't very important for the form tags, but it *is* for form values that contain spaces, for instance.

Is NextPage a valid file name? Or is this a side effect of posting a simplified version of your page??

Cheers,

Imar

Imar;
Thanks for the tips, but what I was really hoping for was someone to say that there is a bug in IE that doesn't allow arrays of select lists. Since all data fields on the form are members of different arrays, and all the arrays are tied together by the first element number (e.g. stuff[1] is associated with morestuff[1], etc.), the select list is just another member of an array. Sadly, it seems that this isn't possible, so what I did was just pass the index number that I'm interested in and in the javascript, I search the appropriate drop-down list for the one that is selected, then take that value and work with it. I was having a problem getting the correct selection, but your previous entry let me get the correct value.
Thanks again!
