我正在创建一个社交网站。我有一个文本框search.php来搜索存储在数据库中的场地。当用户开始输入场地名称时，存储在数据库中的场地名称列表应该加载到 divvenuesearch中。这很好用。我的问题是我需要使 div 内的行venuesearch可点击，这样当用户单击特定行时，该值应该出现在文本框中。

搜索.php 

<script language="javascript">
function showData(str)
{
    if (str.length==0)
    {
        document.getElementById("venuesearch").innerHTML="";
        document.getElementById("venuesearch").style.border="0px";
        return;
    }
    var venue_data = document.getElementById("venue").value;
    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("venuesearch").innerHTML=xmlhttp.responseText;
            document.getElementById("venuesearch").style.border="1px solid #A5ACB2";    
            document.getElementById("venuesearch").style.zIndex = "100";
        }
    }
    xmlhttp.open("GET","aj_search.php?venue="+str,true);
    xmlhttp.send();
}
 </script>
 </head>

<body>

<input id="venue" name="venue" type="text" onkeyup="showData(this.value)" value="Tag venue name"/>
<div id="venuesearch">
</div>
</body>

aj_search.php

  <?php
$dbhandle=mysql_connect("localhost","root","")or die("Unable to connect");
$select=mysql_select_db("scenekey",$dbhandle) or die("Unable to connect");

    if(isset($_GET['venue']))
    {
  $venue_name = $_GET['venue'];
    }
    $hint='';
    $query_get_venue = "SELECT * from sk_accounts WHERE acnt_member_class='venue' and acnt_fname LIKE '".$venue_name."%'";

     $result_query_get_venue = mysql_query($query_get_venue);
     $row_count = mysql_num_rows($result_query_get_venue);
 if($row_count > 0)
 {
    $hint = "<table>";
     while($row = mysql_fetch_array($result_query_get_venue))
     {

         $act_fname = $row['acnt_fname'];
         $act_lname = $row['acnt_lname'];
         $act_name = $act_fname . ' ' . $act_lname;
         $hint.= "<tr><td>".$act_name."</td></tr>";
     }
     $hint .= "</table>";
 }
     if ($hint == "")
     {
   $response="no suggestion";
     }
     else
     {
 $response=$hint;
      }

     //output the response
     echo $response;
      ?>

添加id或class然后为相同或添加javascript功能设置点击事件

 $hint.= "<tr onClick ='hintVal(".$act_name.");'><td>".$act_name."</td></tr>";

在 JavaScript 中：

function hintVal(trVal) {
 alert('tr clicked');
 alert('tr value:'+trVal);
}

为什么不能用Jquery Autocomplete？
