XCe*_*ble 4 html javascript php mysql json
这是从mysql(一行)获取表值的php脚本.并将其作为JSON回应
<?php
$username = "user";
$password = "********";
$hostname = "localhost";
$dbh = mysql_connect($hostname, $username, $password) or die("Unable to
connect to MySQL");
$selected = mysql_select_db("spec",$dbh) or die("Could not select first_test");
$query = "SELECT * FROM user_spec";
$result=mysql_query($query);
$outArray = array();
if ($result) {
while ($row = mysql_fetch_assoc($result)) $outArray[] = $row;
}
echo json_encode($outArray);
?>
这是用于接收和打印json数据的HTML文件.
src ="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"> // $('document').ready(function(){
function Preload() {
$.getJSON("http://localhost/conn_mysql.php", function(jsonData){
$.each(jsonData, function(i,j)
{ alert(j.options);});
});}
// });
</script></head>
<body onLoad="Preload()">
</body>
</html> >
您的PHP需要实际将所有行放在一起:
$query = "SELECT * FROM user_spec";
$result=mysql_query($query);
$outArray = array();
if ($result) {
while ($row = mysql_fetch_assoc($result)) $outArray[] = $row;
}
echo json_encode($outArray);
你的Javascript需要查看每一行..
$.getJSON("/whatever.php", function(jsonData) {
for (var x = 0; x < jsonData.length; x++) {
alert(jsonData[x].options);
}
});
