Question

我从数组对象访问值时遇到问题。

从PHP发送我的对象数组

initiate_data(".json_encode($my_array).");

从javascript检查数组我有这段代码

function initiate_data(my_array){
window.alert(my_array);}

我的数据是

{'name':'name1','surname':'surname1','email':'email1'},{'name':'name2','surname':'surname2','email':'email2'},{'name':'name3','surname':'surname3','email':'email3'}

我也可以访问第一个对象

window.alert(my_array[0]);

结果是

{'name':'name1','surname':'surname1','email':'email1'}

我的问题是我无法从对象访问名称。

我尝试了(my_array[0].name)并且未定义

我用谷歌搜索解决方案，但我找不到特定于我的问题的解决方案

当我尝试访问my_array [0] [0]结果{

感谢您的帮助

console.log给了我这个

其他信息**

php类实现了JsonSerializable，我创建了一个对象数组，希望这有助于澄清我的问题

临时修复

虽然它们可能是更好的方法，但这是我为解决问题所做的工作

var my_obj = JSON.parse(my_array[0]);

现在我可以访问名称

console.log(my_obj.name);

给我 name1

临时修复，直到我能够将所有数组传递给变量。

Answer 1

看起来您的$my_array包含json字符串：

$my_array = array(
    '{"name":"name1","surname":"surname1","email":"email1"}',
    '{"name":"name2","surname":"surname2","email":"email2"}',
    '{"name":"name3","surname":"surname3","email":"email3"}'
);

如果是这种情况，你可以通过简单的implode创建它的javascript数组并添加括号：

initiate_data([".implode(',',$my_array)."]);

Answer 2

是json编码好吗？ http://jsonlint.com/

{
"obj1": {
    "name": "name1",
    "surname": "surname1",
    "email": "email1"
},
"obj3": {
    "name": "name1",
    "surname": "surname1",
    "email": "email1"
},
"obj2": {
    "name": "name1",
    "surname": "surname1",
    "email": "email1"
}
}
