Hi,
I don' think you have worded your question very well. And I am not sure why you want to create this content in this manner (though perhaps its just POC and you'll reveal your true ideas later?).

Anyhow, I think that your problem is your understanding of the getElementByTagName function. This function returns a list of elements matching the argument name. In this case "SELECT". Even if there is only one such element, it will be returned in a list. So you'd need to retrieve it using the item method.. i.e. di.item(0).

I have edited your code, so I could get a feel for what you were after and how you were doing it. I think I've created something along the lines you were after, that is also a little simpler to read and follow.

It seemed sensible to me to pass the node that created the event as an argument to the function, this way you won't have to search for it when it gets there... apart from that; the only other difference is it runs in Mozilla as well... Which is a trend in almost all my code as Mozilla is much simpler to debug than IE.

Hey,
I like the use of the anonymous function pointer... does this work in Internet Explorer?

You should use the code block when your posting code in a post. It makes it easier to reasd and edit..

Checking it out now.

ok, it makes a little more sense now...

I'm afraid I am working on linux here and only using mozilla, so any code I post will only be checked on Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20050110 Firefox/1.0 (Debian package 1.0+dfsg.1-2)

a couple pointers, if your checking for updates now:
[1] You need to set the value of the hidden fields in the txtChange function, you cannot assign them inline like this, a textfield will not update itself like this.
[2] I like you anonymous function, but it won't understand what the other arguments are when it gets called. It understands 'this', because it is called by a dom object that can be referred to that way.. it doesn't understand pname etc because those variables are out of scope.

... there will be more later.

Its not far from giving you what you want i think, you just missed that i gave pname a name attribute:

pname.name = "pname";

you'll need to do this with the other text boxes you'd like to extract as well.

ok, the other change is you'll need to remove all the parameters you added to the txtChange function, refer to my last posts. they are worthless (out of scope).

and you need to actually get the fields you want to assign a value to... otherwise how will they get the value?

you can use my elementOfName function.. just pass document and the name you want. faster would be using the elementById function.. but you'll need to give you input fields unique id's.

Well its easy now...

elementOfName(document, "pName").value  = elementOfName(obj.parentNode, "prname").value;

notice that you search the document node for the node with the name "pName", so this name needs to be unique.

A better way, would be to use the getElementyId function.. but this needs a unique id. i.e.

you'll need to this:

<input type="hidden" name='pName' id="pName">

then you can do this:

document.getElementById("pName").value = elementOfName(obj.parentNode, "prname").value;

I think the problem is my understanding of what you want to achieve. I don't see any problem with the result, from what I understand you are trying to do. Of course I can see why this would make any sense.

Oh and there is no reason to include a taglib here, your not using any JSP elements that I noticed...

Cheers,

foo,

Once again i will xplain the scenario.
i m working in business to bussiness integration tool.we just need the jsp form to get the user input and assign the retrived values into the integraion tool.
for that i need a purchase order format page,which should have the
purchase order header:
purchase-order_id
senderID
receiverID
postatus
podate
expdate
purchase order detail:
productID
productName
productPrice
productQuantity
productSKU
productUPC
the purchase order detail should be generated according to the user needs.
for example
if the user wants 2 product items to be purchased then the detail should generated as follows
productID 1
productName product1
productPrice 89
productQuantity 9
productSKU 678
productUPC 465

productID 2
productName product2
productPrice 890
productQuantity 49
productSKU 6738
productUPC 4635
but the purchase order header should be unique for both the product

purchase-order_id 123
senderID x
receiverID y
postatus open
podate 7/08/2005
expdate 9/08/2005
i dont know the number of items the user is going to order
for that reason i used DOM for dynamic field generation

is there any solution for this problem
please give me the solution

thanks a lot foo..

well, if you looked at the output forwarded to you, you would see that all the dynamically created dom objects send you a value. This value is an array if more that one field with the same name exist.

which is why I don't understand why you'd want to assign the value to your hidden fields... especially not in a manner where it is the last row a user selects that is associated (this seems to be of little use apart from an excellent way of showing how to traverse the DOM).

Here is the name value pairs I got from playing:

SKU='product SKU 3'
UPC='product UPC 3'
btnSubmit='Submit Order'
expDate=''
pId=''
pName='product name 3'
pQty='product quantity 3'
poDate=''
poId=''
poStatus=''
price='product price 3'
prname='product name 1','product name 2','product name 3'
prprice='product price 1','product price 2','product price 3'
prqty='product quantity 1','product quantity 2','product quantity 3'
prsku='product SKU 1','product SKU 2','product SKU 3'
prupc='product UPC 1','product UPC 2','product UPC 3'
senderAddress=''
vendorAddress=''

Now do you see my point? You haven't shown me any good reason for the hidden fields (yet).

yes foo

there is no need for hidden fields i have changed a code a littile bit and its working properly now.Thank you very much for your help.here is my code
