自动提示阿贾克斯PHP [英] auto suggest ajax for php
问题描述
我有一个HTML表单，PHP的纸条和jQuery。我需要一个AJAX code键使自动提示从我的PHP脚本。以下是code ...
i have an html form ,php scrip and jquery. i need a ajax code to make auto suggest from my php script. following is the code...
Form.html
<html>
<head>
<script src="jquery1.6.4.min.js" type="text/javascript"></script>
<script src="jquery.jSuggest.js" type="text/javascript"></script>
<link href="jSuggest.css" rel="stylesheet" type="text/css" />
</head>
<body>
<form id="form1" name="form1" method="post" action="#">
<input type="text" name="TagsInputField" id="TagsInputField"/>
</form>
</body>
</html>
的test.php
<?php
include("bc/script/core/dbcon.php");
$input = $_POST['TagsInputField'];
$data = array();
// query your DataBase here looking for a match to $input
$query = mysql_query("SELECT * FROM user WHERE username LIKE '%$input%'");
while ($row = mysql_fetch_assoc($query)) {
$json = array();
$json['value'] = $row['id'];
$json['name'] = $row['username'];
$data[] = $json;
}
header("Content-type: application/json");
echo json_encode($data);
?>
jquery.jSuggest.js
$(function() {
var dataSource = {
items: [
{
value: "21",
name: "Mick Jagger"},
{
value: "43",
name: "Johnny Storm"},
{
value: "46",
name: "Richard Hatch"},
{
value: "54",
name: "Kelly Slater"},
{
value: "79",
name: "Michael Jordan"}
]
};
$('#TagsInputField').jSuggest({
source: dataSource.items,
selectedItemProp: "name",
seekVal: "name",
selectionAdded: function(elem, data) {
console.log(data.name);
},
selectionRemoved: function(elem, data) {
console.log(data.name);
elem.remove();
}
});
});
注意指针源，它指的是一个对象dataSource.items阅读suggesions。 任何一个可以帮我写一个ajax code阅读suggesions FOM的PHP文件，该文件返回一个JSON。
notice the pointer "source" it is refering to an object "dataSource.items" to read suggesions. can any one help me to write an ajax code to read suggesions fom php file which is returning a json.
