Javascript IE innerHTML from <select>

I am trying to change the innerHTML of an element based on the value of the previous element.

I have javascript correctly capturing the current value, and everything works correctly in Firefox, Safari, Chrome and Opera. IE is a pain.

code example:

<form action="soap.php" method="post">
    <select name="circuitproduct" id="circuitproduct" onchange="bandwidthfunction();">
        <option>Dedicated Voice</option>
        <option>Frame Relay</option>
        <option>ATM</option>
        <option>Dedicated Internet</option>
        <option>IP Solutions Private Port</option>
        <option>IP Solutions Enhanced Port</option>
        <option>Private Line – Domestic</option>
        <option>Int’l Private Line</option>
        <option>Qwest Metro Private Line (QMPL)</option>
        <option>Qwest Metro Ethernet Private Line (QMEPL)</option>
    </select><br />
    <select name="term" id="term">
        <option value="1-Year">1-Year</option>
        <option value="2-Year">2-Year</option>
        <option value="3-Year">3-Year</option>
    </select>
    <select id="bandwidth">
    </select>
    <select id="sublooptype">
    </select>
</form>

javascript sample:

function bandwidthfunction() {
var product = document.getElementById('circuitproduct').value;
    if (product == 'Dedicated Voice') {
        document.getElementById('bandwidth').innerHTML = ('<option value="DS-1">DS-1</option><option value="DS-3">DS-3</option><option value="OC-3">OC-3</option><option value="OC-12">OC-12</option>');
        document.getElementById('sublooptype').innerHTML = ('<option value="Special Access">Special Access</option><option>CO MtPt - Special Access</option><option>CPA Special Access</option>');
    }
    else if (product == 'Frame Relay') {
        document.getElementById('bandwidth').innerHTML = ('<option value="DS-1">DS-1</option><option value="DS-3">DS-3</option><option value="OC-3">OC-3</option><option value="OC-12">OC-12</option>');
        document.getElementById('sublooptype').innerHTML = ('<option value="Special Access">Special Access</option><option>CO MtPt - Special Access</option><option>CPA Special Access</option>');

Well, first of all you have a closing tag for selectwhich you are trying to put inside the element select, which makes the code invalid.

, select . HTML , select , . options.

select, option. option document.createElement . :

var opt = document.createElement('OPTION');
opt.text = 'Choose me';
opt.value = 42;
document.getElementById('bandwidth').options.add(opt);
+9

"select" -Element innerHTML -Property. innerHTML. "bandwith" .

document.getElementById('bandwidth').innerHTML = ('<option value="DS-1">DS-1</option><option value="DS-3">DS-3</option><option value="OC-3">OC-3</option><option value="OC-12">OC-12</option>');

hack, , FF, IE innerHTML .

document.getElementById('bandwidth').outerHTML = document.getElementById('bandwidth').outerHTML.replace( document.getElementById('bandwidth').innerHTML + '</select>' , '<option value="DS-1">DS-1</option><option value="DS-3">DS-3</option><option value="OC-3">OC-3</option><option value="OC-12">OC-12</option>' + '</select>' );

:

function swapInnerHTML(objID,newHTML) {
  var el=document.getElementById(objID);
  el.outerHTML=el.outerHTML.replace(el.innerHTML+'</select>',newHTML+'</select>');
}

APPEND/ADD:
