1.想發ajax用php回傳一個json資料,但是連字串"Hellow world"都回傳不了

2.上程式碼

js程式碼

<script src="./jquery.js"></script>
<script>
$.ajax({
    type:'get',
    url:'./data.php',

    beforeSend:function(){
        console.log("请求发起前")
    },
    success:function(result){
        console.log(result);
    },
    complete:function(){
        console.log('请求完成');
    }
});
</script>

php程式碼

<?php
header("Content-Type:text/html;charset=UTF-8");

echo "Hello,World!!!";
?>

 请求完成

3.不清楚哪裡有錯呢,大家幫忙看一下吧,如果可以返回hello world 那麼下面的json數據可以返回嗎?

php (json)

<?php
header('Content-type: text/json');
$fruits = array (
    "fruits"  => array("a" => "orange", "b" => "banana", "c" => "apple"),
    "numbers" => array(1, 2, 3, 4, 5, 6),
    "holes"   => array("first", 5 => "second", "third")
);
echo json_encode($fruits);
?>
