搜索表单中有两个select选择语句，如何在默认某值的情况下隐藏掉页面中的select框？
代码如下：<div id="schBox" >
<div id="search" onkeypress="return FireDefaultButton(event,'index_sch_btn');">
<form name=search_js1 method=post action='e/search/index.php' onsubmit='return search_check(document.search_js1);'>
<div align=center>搜索:
<select name=show>
<option value=title>标题</option>
<option value=smalltext>简介</option>
<option value=newstext>内容</option>
<option value=writer>作者</option>
<option value=title,smalltext,newstext,writer>搜索全部</option>
</select><select name=classid><option value=0>所有栏目</option>
[!--class--]
</select><input name=keyboard type=text size=13>
<input type=submit name=Submit value=搜索>
</div></form>
</div></div>
代码如下：<div id="schBox" >
<div id="search" onkeypress="return FireDefaultButton(event,'index_sch_btn');">
<form name=search_js1 method=post action='e/search/index.php' onsubmit='return search_check(document.search_js1);'>
<div align=center>搜索:
<select name=show>
<option value=title>标题</option>
<option value=smalltext>简介</option>
<option value=newstext>内容</option>
<option value=writer>作者</option>
<option value=title,smalltext,newstext,writer>搜索全部</option>
</select><select name=classid><option value=0>所有栏目</option>
[!--class--]
</select><input name=keyboard type=text size=13>
<input type=submit name=Submit value=搜索>
</div></form>
</div></div>
</form>后加:
<script language="JavaScript">
<!--
o=document.search_js1;if(o.show.value=='title,smalltext,newstext,writer'&&o.classid.value=='0') document.getElementById('search').style.display='none';
//-->
</script>
利用样式的隐藏
