2/ not just "el.value"
This is an example, so I've written it to show what is happening and how/why, in case of future extension.

as if select.value wouldn’t describe what’s happening… -
It would in the restricted case of a single select.
If however you were traversing a multiple selection list, or some other scenario, then knowing the full derivation would help.
I'm sorry, you seem to be giving me a hard time for just trying to help people?Comment

I am just trying to figure out, what in this case would be the most efficient approach. and of course what the most efficient approach is, can (and probably will) always be debated. and eventually, debates can bring you further in understanding, how JavaScript works.I'm sorry, you seem to be giving me a hard time for just trying to help people?Comment

Don't worry, DMsy2, Dormilich means well :)
On the CDATA, personally, I'd say that you never need it. Why? Put your JavaScript in separate files. Problem solved.
PS. welcome to Bytes and thanks for your input!Comment

When i used the above code in onchange event, the textbox will get set with a value "Undefined" . Please help?Comment
-
I called this function within <Select>, but the text box is set with a value "Undefined" . Since we are using +=, if we select an item thrice from dropdown, then 3 times a word "undefined" gets set to the textbox "Cat_Email" .Code:function addEmail() { // += appends some text to something document.getElementById("textbox").value += this.value; }
Please advise something?Comment
-
how did you attach this function to the event?Comment
-
With the help of an on change event. I enclosed the function within <script> tags as we normally do (within <head> section) and called the function with the help of an onchange event.Comment

may I see the code for this?and called the function with the help of an onchange event.Comment

Now it's working, i made a few changes to the code that you provided.
I replaced += this.value with the below:function addEmail()
{
document.getEle mentById("TextB ox").value += this.value;
}
It is working now. Thanks for your support.document.getEle mentById("TextB ox").value = document.getEle mentById("Selec t").valueComment

ahh, yes. good ole event handling. once you understand it, it’s nearly as cool as sliced bread.Comment

Yes, you are exactly correct. Thanks again for all your support. Your knowledge about Javascript is really outstanding.
Bye :)Comment

you’ll get there, too. though not this time. (pun intended)
I don’t think so, I just happen to do some proper background reading.Your knowledge about Javascript is really outstanding.Comment
