    javascript selectbox

    I am trying to figure this out now for a bit and its driving me nuts.

    I have values in a database that are for a select box they are not in a certain order so .listindex is out of the order. I know the value of the select box and send that to my function. how can i change the selected on without listindex.

    like i know the right value is abc

    <option SELECTED value="abc">abc</select>
    <option value="def">def</select>

    see what i want to do is be able to change the selected from one to the other with a function without using listindex as i know how to do that already. and i can't use a if statement on values like abc as they could change if the database values change.

    I'm still puzzled about how you intend to put this together, but here's how you use javascript to work with the select attribute of an element.

    Code Javascript:
    // set the selected attribute
    optionElement.setAttribute('selected', 'selected');
    // get the selected attribute from the element
    value = optionElement.getAttribute('selected');
    // remove the selected attribute
