对于这个功能企业上还算比较实用,推荐给大家;

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){			//转换成json对象			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 "数据库链接失败";	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($result)){	//判断是否有对应的数据	if(!$row){		$search='';		exit;	}else{		//对查询关键字进行标记		$row['sea'] = str_replace($text, '<font color="red">' .$text. '</font>', $row['sea']);		$search[]=$row;			}}echo json_encode($search);?>
