效果图如下:
代码如下:
HTML代码:(该代码用两种方法实现,一种Jquery,一种原生JS)
<html> <head> <script src="/DelphiRequest/search/js/jquery.js"></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 : 'json', data: {'q':str} , success :function (data) { document.getElementById("livesearch").innerHTML=data; document.getElementById("livesearch").style.border="1px solid #A5ACB2"; } }) } </script> </head> <body> <form> <input type="text" size="30" onkeyup="showResult(this.value)"> <p id="livesearch"></p> </form> </body> </html>
PHP代码如下:(PHP不仅可以考虑直接使用数组,也可以考虑直接查询数据库,获取数据库内容,本代码使用的是数组。)
<?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['q']; $val=array(); $k=0; if (strlen($tmp)>0) { for($i=0;$i<31;$i++){ if(strpos($provinces[$i],$tmp)!==false){ //传递值给val $val[$k]=$provinces[$i]; //下标增加 $k=$k+1; } } //遍历val数组 for($j=0;$j<count($val);$j++) { echo $val[$j]; echo "<br>"; } } ?>
