Dynamic Multi Select Combo Box

[rhull]

I am tryimg to do a dynamic combo box so I am using JSP to switch the 'selected' in and out. Problem is it breaks the HTML. So I need to assign the 'selected' value somehow.

Something Like
<option value=&quot;Fecci&quot; selected=&quot;false&quot;>Fecci </option>
OR
<option value=&quot;Fecci&quot; ????=&quot;selected&quot;>Fecci </option>

Then I can just switch the assigned value!

Basically is there any other way to select a value without just the word 'selected'?

Thanks!

In JavaScript

document.formname.selectlistname.options[n].selected = true

Where n is the index number of the option you want selected. It's zero based so options[0] is option #1, etc..

If you don't know the index number and want to select based on an option value, you would loop through the options like this.

function selectOption(value_ref) {
  for(var i = 0; i < document.formname.selectlistname.length; i++) {
    if(document.formname.selectlistname.options[i].value == value_ref) {
      document.formname.selectlistname.options[i].selected = true
    }
  }
}

Then in your HTML, maybe in the onLoad event handler, you can call that function like this.

selectOption('somevalue')
