Ajax-成功返回多个变量 [英] Ajax - success return more than 1 variable

问题描述

考虑以下示例:

我对php脚本进行Ajax调用，并得到1个结果. PHP回显如下结果；

I do an Ajax call to a php script and get 1 result. PHP echos out the result like below;

 echo json_encode($result);

然后使用Javascript，以下代码将检索结果.

Then in Javascript, the following code will retrieve the result.

         dataType: "JSON",
         success:function(data){
           var result = data
        }

现在，我正在尝试查看是否可以让PHP脚本回显2个结果，并让Javascript能够通过下面的代码来区分它们；

Now I'm trying to see if I can have PHP script echo out 2 result and have Javascript be able to distinguish them with something like the code below;

echo json_encode($result);
echo json_encode($result2);


dataType: "JSON",
success:function(data1,data2){
    var result1 = data1
    var result2 = data2
}

这可能吗?如果可以，怎么办?

Is this possible? If so, how?

推荐答案

您可以在成功返回AJAX时发送值数组:

You can send an array of values on successful return of AJAX:

echo json_encode(array("data1" => $data1, "data2" => $data2));

并像这样打印:

success: function(data){
    var res1 = data.data1
    var res2 = data.data2
}
