BootStrap学习2 typeahead

首先看看这些

<!DOCTYPE html>

<html lang="en">

<head>

    <meta charset="utf-8" />

    <link href="css/bootstrap.css" rel="stylesheet">

</head>

<body>

    <input type="text" id="myElement"/>

        <script src="js/jquery-1.8.0.min.js" type="text/javascript"></script>

        <script src="js/bootstrap.js" type="text/javascript"></script>

        <script type="text/javascript">

        $('#myElement').typeahead({

            source: function (query, process) {

                return $.getJSON(

                    'info2.php',

                    { query: query },

                    function (data) {

                        return process(data.options);

                    });

            }

        });

        </script>

    </body>

    </html>

后台

<?php

$query=$_REQUEST['query'];

$str="";

if(!empty($query))

if (false !== strpos($query, 'or')) {

	$str="{\"options\": [\"ori 1\",\"ori 2\",\"ori 3\",\"ori 4\",\"ori 5\"]} ";

	if(false !== strpos($query,'oric')){

		$str="{\"options\": [\"oricon 1\",\"oricon 2\",\"oricon 3\",\"oricon 4\"]} ";

	}

}else if(false !== strpos($query, 'de')){

 	$str="{\"options\": [\"Dell 1\",\"Dell 2\",\"Dell 3\",\"Dell 4\"]} ";

}else if(false !== strpos($query, 'ro')){

	$str="{\"options\": [\"royal ships\",\"Royal Caribbean\",\"Royal Cruises\",\"royal 4\"]} ";

}

echo $str;

?>

strpos函数就用来检测是否含有子串
