combo box quesion

[ttea]

There is a table in a form contain different combo boxes.

How can i return the combo boxs'values only when it is changed by the user and put the value in the string array??

be more specific. Using onchange would probably help you but it sounds like you just want someone to write a script for you.

I don't mean that asking others to write the script for me,I have also tried many times as i am a beginner of javascript only.I hope you can understand.

I am trying to use onchange, but i don't know how to put the option value in the array.

ok so you mean the option value inside an array?

The selected option is found using :

document.formName.elementName.options[document.formName.elementName.selectedIndex]

You can then add that to the end of an array either by using the index of the array :

var myArray = new Array();
myArray[0] = document.formName.elementName.options[document.formName.elementName.selectedIndex]

Or you could use push to add it directly to the end of the array :

var myArray = new Array();
myArray.push(document.formName.elementName.options[document.formName.elementName.selectedIndex])

If what you actually wanted was to add all the values of the combo inside an array you could use a for loop and add the option's value inside the array using push

var formElm = document.formName.elementName.options;
var len = formElm.length;
var myArray = new Array();

for (var i = 0; i < len; i++)
{
myArray.push(formElm)
}

I hope this helps you out.
