Question

我正在使用ajax来调用服务器并获取一些用户数据。服务器返回一个格式如下的数组：

str = str.decode('utf-8')

然后我尝试使用foreach循环访问数组中的数据

str = str.encode('utf-8')

但这只是记录array:6 [▼ 0 => array:17 [▼ "id" => 334 "provider" => "some_provider" "option_id" => "x124223" "option_title" => "title" "api_parameter" => "parameter" "chart_title" => "title" "chart_color" => "#6a76fc" "chart_target" => "2220" "chart_type" => "line" "chart_size" => "4" "chart_data" => array:7 [▼ 239 => array:2 [▼ "data" => 2114 "created_at" => "14/August" ] 240 => array:2 [▼ "data" => 2114 "created_at" => "15/August" ] 241 => array:2 [▶] 242 => array:2 [▶] 243 => array:2 [▶] 244 => array:2 [▶] 245 => array:2 [▶] ] "average" => 2122.0 "current" => array:2 [▶] "last" => array:2 [▶] "current_status_icon" => "md-trending-neutral" "current_status_color" => "#3DDCF7" "status_message" => "hmm... The needle didnt move." ] 1 => array:17 [▼ "id" => 345 "provider" => "some_other_provider" "option_id" => "x124" "option_title" => "Title" "api_parameter" => "parameter" "chart_title" => "title" "chart_color" => "#6A76FC" "chart_target" => "Set a target" "chart_type" => "line" "chart_size" => "4" "chart_data" => array:7 [▼ 202 => array:2 [▼ "data" => 5 "created_at" => "13/August" ] 203 => array:2 [▼ "data" => 5 "created_at" => "14/August" ] 204 => array:2 [▶] 205 => array:2 [▶] 206 => array:2 [▶] 207 => array:2 [▶] 208 => array:2 [▶] ] "average" => 5.0 "current" => array:2 [▼ "data" => 5 "created_at" => "16/August" ] "last" => array:2 [▼ "data" => 5 "created_at" => "16/August" ] "current_status_icon" => "md-trending-neutral" "current_status_color" => "#3DDCF7" "status_message" => "hmm... The needle didnt move." ]。如何访问嵌套在每个顶级数组中的chart_data？

您的数据结构不明确，因为您共享的结构以PHP表示法输出，并不代表您在JavaScript中收到的JSON。

但我的猜测是这会起作用：

result.forEach(function(item) {
    Object.keys(item.chart_data).forEach(function (key) {
        console.log(item.chart_data[key].data);
    });
});
