下面我就為大家分享一篇jq.ajax+php+mysql實現關鍵字模糊查詢(示例講解)，具有很好的參考價值，希望對大家有所幫助。

對于這個功能企業上還算比較實用，推薦給大家；

index.html

<!DOCTYPE html><html><head><meta charset="utf-8"></head><style>*{margin:0;padding:0;}.text{width:200px;height:30px;line-height:30px;font-size:14px;outline:none;}ul{width:200px;height:auto;border:1px solid #999;border-top:none;}ul li{width:200px;height:30px;line-height:30px;font-size:14px;}li:hover{background:#ddd;}</style><body><input type="text" class="text" name="text"><ul class="sea"></ul><script type="text/javascript" src="http://code.jquery.com/jquery-2.1.1.min.js"></script><script type="text/javascript">$(".text").bind("input", function() { if($(this).val().length>0){search();}else{$(".sea").html('');}})function search(){$.ajax({type:"GET",url:"sea.php",data:{"text":$(".text").val()},success:function(response){//轉換成json對象eval("var json="+response);//console.log(json)var str="";for(var i=0;i<json.length;i++){str += "<li>" + json[i].sea + "</li>";}$(".sea").html(str);}})}</script></body></html>

sea.php

<?php$con = mysqli_connect("localhost","username","password");if(!$con){echo "數據庫鏈接失敗";exit;}mysqli_select_db($con,'jwhuang');mysqli_query($con,'set names utf-8');$text= isset($_GET['text']) ? trim($_GET['text']) : '';$result=mysqli_query($con,"select * from search where sea LIKE '{$text}%' ");$search=array();while($row=mysqli_fetch_assoc($result)){//判斷是否有對應的數據if(!$row){$search='';exit;}else{//對查詢關鍵字進行標記$row['sea'] = str_replace($text, '<font color="red">' .$text. '</font>', $row['sea']);$search[]=$row;}}echo json_encode($search);?>
