fields with style display:none displayed in IE

[plsHelpMe]

Hi All,

I am facing a weired issue. I am having a search form with some of the fields on it and a button which submits these fields values.
Functionaly everything is working fine but sometimes when i try to submit my search form i can see the fields which are hidden using the style "display:none " visible for a moment just before my page is submitted. I am providing the html code behind those components as follows:

<div class="formline topalign" id="divdirectionTextBox" >
<input type="text" name="directionTextBox" size="45" value="" onkeypress="subEnterKeyPressHandler(event)" class="input marginright10" id="directionTextBox">
</div>
<div class="formline topalign" id="divisionDropdown1" style="display: none;">
<select name="divisionDropDown1" onchange="showFieldsDivisionDD(searchFormObject.di visionDropDown1);" class="select" id="divisionDropDown1Style"> <option value="1">1</option>
<option value="2">2</option>
</select>
</div>
<div class="formline topalign" id="divisionDropdown2" style="display: none;">
<select name="divisionDropDown2" class="select" id="divisionDropDown2Style">
<option value="a">a</option>
<option value="b">b</option>
</select>
</div>

here, initially only the div with the id "divdirectionTextBox" is visible, but when i try to submit the form the fields with the ids "divisionDropdown1" and "divisionDropdown2" gets visible while the field "divdirectionTextBox" hides.

If anyone has encountered such a problem then please share the solution with me.
Thanks

What are your javascript functions doing?
Since there is no actual "form" there, the html side will not be doing any "submitting".
So whatever it's doing, it's doing in the javascript.

Yup on the click of the button present on my search form im submitting the form using the javascript as follows:

function fnSubmitSearchForm(target,flag){
searchFormObject.dispatch.value=target;
searchFormObject.persistenceNeeded.value=flag;
searchFormObject.submit();
}

All these things are working finr in mozilla but display the hidden field in the IE browser.
