我正在尝试使用 jquery token 输入插件 http://loopj.com/jquery-tokeninput/ 从数据库填充数据.但什么也没有出现。我想知道我哪里出错了。
我接受任何替代方法
我搜索的每个示例似乎都不起作用。
我的索引页
<script type="text/javascript"
src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js">
</script>
<script type="text/javascript" src="src/jquery.tokeninput.js"></script>
<link rel="stylesheet" href="styles/token-input.css" type="text/css" />
<link rel="stylesheet" href="styles/token-input-facebook.css" type="text/css" />
<div>
<input type="text" id="tagcool" name="blah" />
<input type="button" value="Submit" />
<script type="text/javascript">
$(document).ready(function() {
$("#tagcool").tokenInput("phpsearch.php", {
theme: "facebook",
preventDuplicates: true,
});
});
</script>
还有我的 PHP 页面
<?php
$link = mysqli_connect("localhost","root","","dbname") or die("Couldn't make connection.");
$look = $_GET['q'];
$arr = array();
$rs = mysqli_query($link,"SELECT * FROM `country` WHERE name like '%".$look."%'");
# Collect the results
while($obj = mysqli_fetch_object($rs)) {
$arr[] = $obj;
}
# JSON-encode the response
$json_response = json_encode($arr);
# Optionally: Wrap the response in a callback function for JSONP cross-domain support
if($_GET["callback"]) {
$json_response = $_GET["callback"] . "(" . $json_response . ")";
}
# Return the response
echo $json_response;
?>
我的数据库示例
最佳答案
这有效。您需要根据您的设置更改下面的一些编码。
HTML
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="styles/token-input-facebook.css" type="text/css" />
</head>
<body>
<form name='jqueryAutocompleteForm' id='jqueryAutocompleteForm'>
<label for='query'>Search:</label>
<input type='text' name='q' class='form-control input-lg' id='query' placeholder='Please Start Typing'>
<input type='submit' value='Submit' class='btn btn-info'>
</form>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script type="text/javascript" src="src/jquery.tokeninput.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$("#query").tokenInput("php.php", {
theme: "facebook"
});
});
</script>
</body>
</html>
注意:确保“jquery.tokeninput.js”和“php to json”的路径(在我的例子中为“php.php”和你的“phpsearch.php”)是正确的。
php.php
<?php
//open connection to mysql db
$connection = mysqli_connect("localhost","root","","tags") or die("Error " . mysqli_error($connection));
$s = $_GET["q"];
//fetch table rows from mysql db
$sql = "SELECT name from mytable WHERE name LIKE '%".$s."%'";
$result = mysqli_query($connection, $sql) or die("Error in Selecting " . mysqli_error($connection));
//create an array
$emparray = array();
while($row =mysqli_fetch_assoc($result))
{
$emparray[] = $row;
}
echo json_encode($emparray);
//close the db connection
mysqli_close($connection);
?>
替换选择查询，“$sql = "SELECT name from mytable WHERE name LIKE '%".$s."%'";"与你的。
如果您需要知道，我的数据库只有 1 个表，其中有 2 列 1.id、2、name。
