Hi,

I created a multiple select box wich i would like to have one variable with all the results selected on the multiple select box such as variable_name = "result1|result2|result3"

This is what i have so far:

oSelect = document.getElementById ('s1');
var iNumSelected = 0;

   for (var iCount=0; oSelect.options[iCount]; iCount++) {
        if (oSelect.options[iCount].selected == true) {
            iNumSelected ++;
            alert(oSelect[iCount].value); // this part alerts all the result within the loop
        }
   }

Now what i exactly need is to have a variable called "test" outside of the loop wich i have all the selected results separated with an "|", so that when i do alert(test) displays all results as a one result.

Hope someone can help

Thanks

Declare a variable 'test' outside the loop and inside the loop append the value of the selected option along with a '|' to `test'. Try it. Did you get the desired result? If no, then why? What seems to be missing here? What do you think needs to be done to make it work the way you expect?

Hi, thanks for the reply but that's my problem on how to append everything on the variable , on php i usually do $test .= $array_var."|"; and outside the loop i just do echo $test, now how's that done in javascript?

Thanks

            iNumSelected ++;
            str+= "|" + oSelect.options[iCount].value
        }
   }
