问题：

<form...>下面的<input type="hidden" name="sortBy" id="sortBy" value="${sortBy}">占据物理位置的情况，代码如下：

<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，红色的隐藏输入框直接在form标签下面，结果出现在ie下显示失真的情况，隐藏输入框占据物理空间，在ie里留下空白的部分。而在Firefox下显示正常。

解决方法：

把隐藏输入框放在form标签的最后面，即在</form>之上，ie下显示即可恢复正常。代码如下：

<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>
