I am now doing the multiselect. I can now multiselect and get the values but I do not know how to spilt the values. This is the code I am using, I understand what it does but I do not know how to seperate the values.

Either I'am going blind or you didn't post your code.

As for seperating the values in a multiselect that is explained in the page I posted a link to back in comment #6.

You might also want to take a look at some string functions

http://www.w3schools.com/js/js_obj_string.asp

Opps looks like I forgot haha. I was in a hurry yesterday.

Here are the codes.

function loopSelected()
{
var BATfileObj = document.getElementById('BATfile');
var selectedArray = new Array();
var selObj = document.getElementById('select1');
var i;
var count = 0;
for (i=0; i<selObj.options.length; i++) {
if (selObj.options[i].selected) {
selectedArray[count] = selObj.options[i].value;
count++;
}
}
BATfileObj.value = selectedArray;
}

I got it from the codes from the tutorial you give me. The values it gives out are in this form value1,value2,value3,value4. I want to seperate the values. How do you do it.

Ehh, you already got the values seperated inside the 'for' loop on this line

Code:

---

selectedArray[count] = selObj.options[i].value;

---

I assume what you meant to say, was that you want each of values the values on a line by itself, in the text area.
Again You obviouly haven't been paying any attention to what I have been telling you about concatenating strings.
To get the select values, each on a line by itself, you could just replace the above line with

Code:

---

selectedArray += selObj.options[i].value + "\n";

---

Although this is bit of a misnomer on my part, since selectArray is now a string rather than a Array of strings.

And once again please read some more tutorials and try to put a lot more work into your problems before asking for help. As far as I'am concerned you are rapidly becoming the boy how cried wolf.

Thanks. What I don't understand is the array part I thought that

for (i=0; i<selObj.options.length; i++) {
if (selObj.options[i].selected) {
selectedArray[count] = selObj.options[i].value;
count++;

this part just all the values and put it together I was not sure so I ask.

Sorry for the problem I cause. But I thank you for teaching me alot.

But one more question what is the count and count++ for?

Thanks

Again I must strongly suggest that you go read some tutorials, the ++ operator is explained at http://www.w3schools.com/js/js_operators.asp

You are building an array of the selected options from all the options, Every time you find a selected option you insert the value into result array at position count. And increment the count variable so that the next selected option will be inserted at the next position in the result array.

Thank you I understand what you mean. I know what a ++ means I was just wondering what the count is for as there is var i for the values. So the count is for selected values. Thanks alot.
