Hi Brian,
From your description, you'd like to split a string into an array in
javascript code and dynamically create some items of
a html listbox according to the values in the array via javascript , yes?
As for this problem, here are my suggestions:
1. The string spliting can be done by the split() member function of the
text object, for example
var txt = "user1;user2;user3";
var array = txt.split(";");
2. And as for dynamically create option items for listbox( infact it is a
<select> html element), we can use the following code:
//modelSelect is an <select > html element
modelSelect.options.length = 0; // Clear the popup
modelSelect.options[0] = new Option("Explorer");
modelSelect.options[1] = new Option("Mustang");
modelSelect.options[2] = new Option("Probe");
And here is a web tech article discussing this:
#Focus on JavaScript --- Modifying Items in a Dropdown List

In addition, here a simple demo page , you may also have a look if you feel
anything unclear:

lst.options.length = 0;
var i=0;
for(i=0;i<arr_users.length;i++)
