Question

Output contents of a fieldset

Asked by: chtru

I've been following the demo at
http://www.webreference.com/programming/javascript/mk/column2/
Specifically the part where you can drag and drop items between fieldsets.

I'd like to extend that to send the contents of the fieldset on clicking a button.  

The part I'm having trouble with is what javascript code would I use to return the value of specific <fieldset> so that I can submit them somewhere?

Obviously since you can drag and drop between the fieldsets, I need to have submitted what's in the fieldsets after they've been dragged and dropped!

Thanks.

chtru: I couldn't find the word 'fieldset' on the web-page whose link you have provided. Could you explain, what exactly do you mean by the 'fieldset'?

 

by: chtruPosted on 2009-11-04 at 20:48:58ID: 25746854

Hi Gurvinder.

If I view the source of the page, the section i'm interested in is enclosed in an html tag <fieldset id="Demo4">
So I'm presuming it's some kind of element that we can get the values from?

 

by: gurvinder372Posted on 2009-11-04 at 21:00:14ID: 25746886

fieldset is a way of grouping the related elements in a form
See http://www.w3schools.com/tags/tag_fieldset.asp for reference.

Regarding the original problem,
If you just want the contents of the fieldset, then it should be straightforward, since you can just get the contents of any html element using javascript (something like elementById.Value).
If you want the contents of the related elements inside the fieldset, then you have to achieve this by naming the internal elements in such a way that you can retrieve their value by just giving the name of the fieldset. For example, if the fieldset name is fs1, then the textboxes inside the field set will be fs1txt1, fs1txt2 etc.

Let me know if this helped you

Hi Gurvinder.  The problem I have is I need to know which box they are in, I think they end up in different divs?  Ie I need to know if the element is in box 1, 2 or 3.

 

by: gurvinder372Posted on 2009-11-04 at 22:33:26ID: 25747176

You can check the parent node of the div element that you are dragging.
Use the following link as reference

Ok sounds good.  I'm really bad at javascript, so what function would I need to write that on submission would go to the div with an id of "DragContainer4" and "DragContainer5" and return the elements? I tried using
var output = DragContainer4.getElementsByTagName('div')
but when I alert(output) i get [object].
which is presumably because it's an array?
how would I actually see what's in the array? ie convert to string?

thanks!

You don't need to directly get the object of the DragContainer here because that is not being dragged here. Instead, you need to get the Object of div with class 'DragBox' ie for example Item22.
After dragging Item22 you need to check the new parent node of Item22.
Using  
var parentObject = document.body.getElementsByTagName("Item22").parentNode.id;
you will get the name of the parent.

Once you have got this Id, you know the final location of the box that you have dragged.
