Real-time search prompt implemented in PHP

This time I will bring you real-time search prompts implemented in PHP. What are the precautions for implementing real-time search prompts in PHP? Here are practical cases, let’s take a look.

The example in this article describes the real-time search prompt function implemented by PHP+JS. Share it with everyone for your reference, the details are as follows:

The rendering is as follows:

The code is as follows:

HTML code: (This code Use two methods to implement, one is Jquery, the other is native JS)

  <script></script>
  <script>
/*用原生js实现
//    function showResult(str)
//    {
//      if (str.length==0)
//      {
//        document.getElementById("livesearch").innerHTML="";
//        document.getElementById("livesearch").style.border="0px";
//        return;
//      }
//      if (window.XMLHttpRequest)
//      {// IE7+, Firefox, Chrome, Opera, Safari 浏览器执行
//        xmlhttp=new XMLHttpRequest();
//      }
//      else
//      {// IE6, IE5 浏览器执行
//        xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
//      }
//      xmlhttp.onreadystatechange=function()
//      {
//        if (xmlhttp.readyState==4 && xmlhttp.status==200)
//        {
//          document.getElementById("livesearch").innerHTML=xmlhttp.responseText;
//          document.getElementById("livesearch").style.border="1px solid #A5ACB2";
//        }
//      }
//      xmlhttp.open("GET","livesearch.php?q="+str,true);
//      xmlhttp.send();
//    }
*/
//用jquery实现
     function showResult(str){
       $.ajax({
         type: "GET",
         url : "livesearch.php",
         datatype : &#39;json&#39;,
         data: {&#39;q&#39;:str} ,
         success :function (data) {
           document.getElementById("livesearch").innerHTML=data;
           document.getElementById("livesearch").style.border="1px solid #A5ACB2";
         }
       })
     }
  </script>

     

PHP code is as follows: (PHP can not only consider using arrays directly, but also directly query the database to obtain the database Content, this code uses an array. )

<?php $provinces=array("beijing","tianjin","shanghai","chongqing","hebei","henan","heilongjiang","jilin","changchun",
  "shandong","anhui","shanxi","guangzhou","yunnan","hainan","xizang","qinghai","fujian","guizhou","jiangsu",
  "zhejiang","guangzhou","yunan","hainan","xizang","neimenggu","sichuan","gansu","ningxia","xianggang","aomen");
$tmp=$_GET[&#39;q&#39;];
$val=array();
$k=0;
if (strlen($tmp)>0)
{
  for($i=0;$i";
  }
}
?>
