切换标签页Firefox下正常，IE下第一个标签页内容无法切换出来

[mercury1231]

做了一个切换标签页的东西，可是不知道为什么Firefox下面运行的很好，但是IE里第一个标签页内容切换不出来（首次加载正常）？
是不是IE对这个支持有什么不对的地方？有一个地方嵌套了HTML代码，里面含有div，table等元素，不知道有没有影响？

<div id="product-details" class="product-collateral">
    	<script type="text/javascript">
			function showTab(tabHeadId,tabContentId)
			{
				var tabDiv = document.getElementById("product-details-contents");
				var taContents = tabDiv.childNodes;
				
				for(i=0; i<taContents.length; i++) {
					if(taContents[i].id!=null && taContents[i].className == 'collateral-box') {
						taContents[i].style.display = 'none';
					}
				}
				
				document.getElementById(tabContentId).style.display = '';
				//alert(document.getElementById(tabContentId).style.display);

				var tabHeads = document.getElementById('product-details-tabs').getElementsByTagName('span');
				for(i=0; i<tabHeads.length; i++) {
					tabHeads[i].className='tab';
				}
				
				document.getElementById(tabHeadId).className='curtab';
				document.getElementById(tabHeadId).blur();
			}
		</script>
    
    	    	<div id="product-details-tabs" class="tabs">
    		<span id="description-tab" class="curtab" onclick="javascript:showTab('description-tab', 'description');">Description</span>
    		<span id="specification-tab" class="tab" onclick="javascript:showTab('specification-tab', 'specification');">Specification</span>
    		<span id="warranty-tab" class="tab" onclick="javascript:showTab('warranty-tab', 'warranty');">Warranty</span>

    		<span id="review-tab" class="tab" onclick="javascript:showTab('review-tab', 'review');">Reviews</span>
    	</div>
    	    	<div id="product-details-contents" class="collateral-boxes">
