<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 = atributePathInputValue id = atributePathInputValue value = $ {attributePathInputValue}>
<input type = hidden name = prMitemSperpage id = prMitemSperpage value = $ {pagingbean.itemsperpage}>
<input type = name tersembunyi = 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 yaitu 下显示失真的情况 ， 隐藏输入框占据物理空间 ， 在 yaitu 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 Formulir 标签的最后面 ， 即在 </form> 之上 ， yaitu 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>
