改代码实现ajax得到结果并且显示出结果，如截图：
-
<html>
-
<title>ajax autocomplete</title>
-
<head>
-
<style type="text/css" media="screen">
-
.onmouset_out{
-
background-color: #99CCFF;
-
padding: 2px 6px 2px 6px;
-
}
-
.onmouset_over{
-
background-color: #006600;
-
padding: 2px 6px 2px 6px;
-
}
-
#result_display{
-
border: 1px solid #FFFFFF;
-
}
-
</style>
-
-
<script type="text/javascript">
-
