Javascript and list boxes

[eva21]

I have a 2 list boxes:

echo("<Select size=3 MULTIPLE onchange='getMedia(" . $rows['id'] . ")' name='" . $rows['id'] . "_teach' id='" . $rows['id'] . "_teach'>");

<option> 1 </option>

<option> 2 </option>

echo("<Select size=3 MULTIPLE onchange='getMedia(" . $rows['id'] . ")' name='" . $rows['id'] . "_pract' id='" . $rows['id'] . "_pract'>");

<option> 3 </option>

<option> 4 </option>

 

These are filled with information in javascript. This works fine, but how do i know what is selected by the user in javascript? For example if the user selects "1, 2, 3, and 4"...I want to alert that to me what they selected using javascript. Any help would be appreciated.

You'll have to loop through the options in the selects and check if they are selected.

I have this:

 

for (i=0;i<=mediaT.length-1;i++)

{

var y = media.options.selected

alert(y);

}

 

Not working though, it doesnt even go thru loop.
