xiyunt

我有一个JavaScript选择搜索引擎的脚本,但需要在搜索按钮上加图片,如何实现?
下面的好象不行,麻烦老大们帮忙写一下,谢谢!
<form Name="InputForm">;
<script language="JavaScript">;
var FirstForm;
function StartSearch()
{
document.forms[FirstForm+document.InputForm.SearchSelect.
selectedIndex].elements[0].value=document.InputForm.word.value;
document.forms[FirstForm+document.InputForm.SearchSelect.
selectedIndex].submit();
}
</script>;
<INPUT name=word onfocus=this.select()
                 onblur="if (value ==''){value='请输入关键词'}"
                 onclick="if(this.value=='请输入关键词') this.value=''"
                 onmouseover=this.focus()
                 value=请输入关键词 size=18 >;<select Name="SearchSelect" size="1">;
<option value="1" selected>;本站</option>;
<option value="2">;百度</option>;
<input type="button" value=" 搜索 " onClick="StartSearch()">; <script language="JavaScript">;
FirstForm=document.forms.length
</script>;
</form>;
<form action="http://www.baidu.com/baidu" target="_blank">;
<input type="hidden" name="word" value>;
<input type="hidden" value="all" name="category">;
</form>;
<form METHOD="GET" ACTION="http://www.baidu.com/baidu" target="_blank">;
