修改AJAX即时搜索

Question

I have build an instant search with AJAX using this tutorial, I am getting instant result but the problem is the div in which result comes stays open there. 我已经使用本教程使用AJAX构建了即时搜索功能，但我得到的是即时结果，但问题是结果所在的div仍然在那里打开。

I want to modify it like after getting instant result, then 我想像得到即时结果后那样修改它，然后

when clicked anywhere on page the result(div) should disappear. 当单击页面上的任何位置时，结果（div）应该消失。
and when mouse-over again on input field result(div) should reappear. 当再次将鼠标悬停在输入字段result（div）上时，应重新出现。

AJAX Code AJAX代码

    <script type="text/javascript">
function showResult(str)
{
if (str.length==0)
  {
  document.getElementById("search-result").innerHTML="";
  document.getElementById("search-result").style.border="0px";
  return;
  }
if (window.XMLHttpRequest)
  {// code for IE7+, Firefox, Chrome, Opera, Safari
  xmlhttp=new XMLHttpRequest();
  }
else
  {// code for IE6, IE5
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xmlhttp.onreadystatechange=function()
  {
  if (xmlhttp.readyState==4 && xmlhttp.status==200)
    {
    document.getElementById("search-result").innerHTML=xmlhttp.responseText;
    document.getElementById("search-result").style.border="1px solid #A5ACB2";
    }
  }
xmlhttp.open("GET","instant-search.php?keyword="+str,true);
xmlhttp.send();
}
</script>

HTML Code HTML代码

    <div id="search">
<form action="" method="get" id="search-form" >

<input name="" type="" size="" id="search-input" onkeydown="showResult(this.value)"/>

<select name="" id="search-select">
<option value="all" >All</option>
<input type="hidden" name="" value="" />
</select>

<input type="submit" value="Search" id="search-btn" /> 

</form>      
</div>
<div id="search-result"></div>

PHP Codes are simple MySQL Full Text Search query. PHP代码是简单的MySQL全文搜索查询。

I tried like adding this but nothing happens 我尝试添加它，但没有任何反应

        <input name="keyword" type="text" size="50" id="search-input" onkeydown="showResult(this.value)" onclick="(this.value==this.defaultValue) this.value='';"  onmouseout="showResult(this.value='';)"/>

Please suggest any way of doing this. 请提出任何可行的方法。

Thanks. 谢谢。

A nasty way 讨厌的方式

<body>
<div id="main" onclick="fx(0)">

<div id="search">
<form action="" method="get" id="search-form" >
<input name="" type="" size="" id="search-input" onkeydown="showResult(this.value)"/>
<select name="" id="search-select">
<option value="all" >All</option>
<input type="hidden" name="" value="" />
</select>
<input type="submit" value="Search" id="search-btn" /> 
</form>      
</div>
<div id="search-result" onclick="fx(1)"></div>

</div>
</body>

<script>
function fx(var flag)
{
  // document.getElementById(theIdYouWantToShowHide).style.display="none" or inline or block ...
}
</script>
