我试图让对象与数据的数组从我的数据库到jQuery来呈现在网站上。

I'm trying to get an array of objects with data from my database into jquery to render on a website.

例如： 使用example.php

ex: example.php

<?php
function testFunction() {

$data = array()
$mydata = new stdClass;
$mydata->example = 'test';
$data[] = $mydata
return json_encode($data);
}

echo testFunction();
?>

前 index.html的

ex index.html

<script>
$.ajax({
                    type: 'POST',
                    url: 'example.php',
                    data: {map: map},   
                    cache: false,
                    dataType: 'json',                 
                    success: function(response) {
                      console.log(response[0].example);
                    }
});

</script>

输出：

执行console.log（响应）;

console.log(response);

[测试，$家族：函数，$构造：函数，每个：函数，克隆：功能，清洁：函数...]

["test", $family: function, $constructor: function, each: function, clone: function, clean: function…]

的console.log（响应[0] .EXAMPLE）;

console.log(response[0].example);

未定义

所以基本上，我收到的响应很好，当我登录它它给了我一个结构，它是有道理的。不过，我似乎无法找到访问数组里面我的对象的正确方式，比如我上面只返回undefined。什么是正确的语法为这个吗？

So essentially, I receive the response fine, when I log it it gives me a structure that makes sense. however I can't seem to find the correct way of accessing my objects inside the array, the example I have above only returns undefined. What is the correct syntax for this please?

推荐答案

您需要 JSON.parse（响应）; 的响应。你应该能像你需要再访问它。

You need to JSON.parse(response); the response. You should be able to access it like you need then..

var parsed_reply = JSON.parse(response);

修改后居然在看code：

PHP

<?php

$data['example'] = "test";

echo json_encode($data);

?>

JAVASCRIPT

JAVASCRIPT

<script>
$.ajax({
                type: 'POST',
                url: 'example.php',
                data: {map: map},   
                cache: false,
                dataType: 'json',                 
                success: function(response) {
                  console.log(response['example']);
                }
});

</script>

OUTPUT：测试

OUTPUT: "test"
