我有一个 HTML 页面，其中包含单选按钮、组合框、文本字段和一个搜索按钮。我想当我在文本字段中输入文本然后选择一个单选按钮和组合框时，当我单击搜索按钮时，数据库的结果将基于此值显示：单选按钮的值 + 组合框的值 + 的值文本字段。我希望这些值作为 Ajax 执行的 ShowResult(str) 函数的参数。我的代码是：

function ShowResult(str)
{
if (str=="")
  {
  document.getElementById("Div1").innerHTML="";
  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("div1").innerHTML=xmlhttp.responseText;
    }
  }
xmlhttp.open("GET","getresult.asp?q="+str,true);
xmlhttp.send();
}
</script>
<html>
<head>
    <title>Untitled Page</title>
</head>
<body>
<form>
<input id="Text1" type="text" />
<input id="Button1" type="button" value="Search" onclick="ShowResult(str)" /><br />
 <select name="combox" >
 <option value="Des">Descending</option>
 <option value="Ase">Ascending</option>
 </select><br />
<input type="radio" name="group1" value="Added_date"/> Added_date<br/>
<input type="radio" name="group1" value="Price"/>      Price<br /> 
<input type="radio" name="group1" value="Name"/>       Name<br/>
   </form>

   <div id="Div1" ></div>
</body>
</html>

但我不知道这些值是如何传递给 ShowResult(str) 的？？？请帮我。
