問題：
<form...>下面的<input type="hidden" name="sortBy" id="sortBy" value="${sortBy}">占據物理位置的情況，代碼如下：
<form name="header_product_search_form" method="post" id="header_product_search_form" action="${ctxPath }/products/productsSearch.html?doAction=productSearchAction">
<input type="hidden" name="headSearchCategoryPath" id="headSearchCategoryPath" value="${categoryPath }">
<input type="hidden" name="headSearchAttributePath" id="headSearchAttributePath" value="${headSearchAttributePath }">
<input type="hidden" name="attributePathInputValue" id="attributePathInputValue" value="${attributePathInputValue}">
<input type="hidden" name="PrmItemsPerPage" id="PrmItemsPerPage" value="${pagingBean.itemsPerPage}">
<input type="hidden" name="PrmPageNo" id="PrmPageNo" value="${pagingBean.currentPage}">
<input type="hidden" name="PrmTotalItems" id="PrmTotalItems" value="${pagingBean.numberOfItems}">
<input type="hidden" name="PrmTotalPages" id="PrmTotalPages" value="${pagingBean.numberOfPages}">
<input type="hidden" name="sortBy" id="sortBy" value="${sortBy}">
..............
..............
</form>
如上，紅色的隱藏輸入框直接在form標簽下面，結果出現在ie下顯示失真的情況，隱藏輸入框占據物理空間，在ie裡留下空白的部分。而在Firefox下顯示正常。
解決方法：
把隱藏輸入框放在form標簽的最後面，即在</form>之上，ie下顯示即可恢復正常。代碼如下：
<form name="header_product_search_form" method="post" id="header_product_search_form" action="${ctxPath }/products/productsSearch.html?doAction=productSearchAction">
..............
..............
<input type="hidden" name="headSearchCategoryPath" id="headSearchCategoryPath" value="${categoryPath }">
<input type="hidden" name="headSearchAttributePath" id="headSearchAttributePath" value="${headSearchAttributePath }">
<input type="hidden" name="attributePathInputValue" id="attributePathInputValue" value="${attributePathInputValue}">
<input type="hidden" name="PrmItemsPerPage" id="PrmItemsPerPage" value="${pagingBean.itemsPerPage}">
<input type="hidden" name="PrmPageNo" id="PrmPageNo" value="${pagingBean.currentPage}">
<input type="hidden" name="PrmTotalItems" id="PrmTotalItems" value="${pagingBean.numberOfItems}">
<input type="hidden" name="PrmTotalPages" id="PrmTotalPages" value="${pagingBean.numberOfPages}">
<input type="hidden" name="sortBy" id="sortBy" value="${sortBy}">
</form>
