SYMPTOMS

When you set the innerHTML property of the Select object, the changes do not take effect correctly.

RESOLUTION

If you must use innerHTML, a workaround is to use a Div object to wrap the SELECT element and then set the innerHTML property for the Div object. For example: 
<html>
<head>
<title>My Example</title>
<script language="Javascript">
var origDivHTML;

function init()
{
   origDivHTML = myDiv.innerHTML;
}

function setValues() 
{
   var oldinnerHTML = "your original innerHTML: " + yourDiv.innerHTML ; 	
   alert(oldinnerHTML);
   yourDiv.innerHTML = origDivHTML;
	 
   var curinnerHTML = "your current innerHTML: " + yourDiv.innerHTML ; 
   alert(curinnerHTML); 
}
</script>
</head>

<body onload="init()">

<div id="myDiv">
  <select name="firstSelect" size="1" >
    <option>11111</option>
    <option>22222</option>
    <option>33333</option>
  </select>
</div>

<div id="yourDiv">
  <select name="secondSelect" size="1" >
    <option>aaaa</option>
    <option>bbbb</option>
    <option>cccc</option>
  </select>
</div>
<button onclick = "setValues();">click me to set the values</button>
</body>
</html>

Ideally, you should use the options collection to add the options of a SELECT element. The following code shows three ways to programmatically add options to the SELECT element: 
<HTML>
<HEAD>
<TITLE></TITLE>
</HEAD>
<BODY>

<script>

function fill_select1() {

	for(var i=0; i < 100; i++) {
			select1.options[i] = new Option(i,i);
		}
}

function fill_select2() {

		var sOpts = "<SELECT>";
		for (var i=0;i<100;i++)
		{
			sOpts += '<OPTION VALUE="' + i + '">' + i + '</OPTION>\n';
		}
	
		select2.outerHTML = sOpts  + "</SELECT>";
}

function fill_select3() {

	for(var i=0; i < 100; i++) {
		   var oOption = document.createElement("OPTION");
		   oOption.text="Option:  " + i;
		   oOption.value=i;
		   document.all.select3.add(oOption)
		}
}



</script>

<H2>SELECT Box Population</H2>

<SELECT id=select1 name=select1></SELECT>
<INPUT type="button" value="Populate with options list" id=button1 
name=button1 onclick="fill_select1();"><BR><BR>
<SELECT id=select2 name=select2></SELECT> 
<INPUT type="button" value="Populate with outerHTML" id=button2 
name=button2 onclick="fill_select2();"><BR><BR>
<SELECT id=select3 name=select3></SELECT>
<INPUT type="button" value="Populate with using createElement" id=button3 
name=button3 onclick="fill_select3();">

</BODY>
</HTML>

Steps to Reproduce Behavior

The following sample code illustrates this bug: 
<html>
<head>
<script language="JavaScript">  
function test()
{
    var objSelect = document.all.idSelect;
    var strOrigHTML     = objSelect.innerHTML;
    objSelect.innerHTML = strOrigHTML;
    var strNewHTML      = objSelect.innerHTML;

    if (strNewHTML == strOrigHTML)
        alert("Test passed.");
    else
        alert("Test failed: innerHTML = " + strNewHTML );
}
</script>
</head>
<body>
  <select id="idSelect">
    <option value="line1">Option 1</option>
    <option value="line2">Option 2</option>
  </select>
  <input type="button" value="test" onClick="test()" />
