jQuery-將字符串轉換為數組

Question

我正在從數據庫中檢索一個字符串，該字符串是一個數組。

 jq.ajax({
            type: "GET",
            url: "/Method/",
            success: function () {
               // Sample data     
               var data = "[{                                   
                              name: "Santro",
                              canvas: "1"
                             }, {                                       
                              name: "Tata",
                              canvas: "2"
                           }]";

通過AJAX調用獲取數據后，我得到了字符串。

如何將此字符串轉換為數組？

Answer 1

嘗試這個

jq.ajax({
        type: "GET",
        url: "/Method/",
        dataType: "JSON",
        success: function (obj) {
            $.map(obj, function(el) 
               { 
                    return el // as array 
               });
        }

Answer 2

您的php應該看起來像這樣：

 public function actionTest2() {
    $arr[] = [
        'name' => 'saura',
        'canvas' => 1,
    ];
    $arr[] = [
        'name' => 'tat',
        'canvas' => 3,
    ];
  //$arr like your db result 
    echo json_encode($arr);
}

和php輸出： [{"name":"saura","canvas":1},{"name":"tat","canvas":3}]

您的js應該看起來像這樣：

jq.ajax({
    type: "GET",
    url: "test2",
    dataType: "JSON",
    success: function (data) {
      var obj = jQuery.parseJSON(data);
       console.log(obj[0]); // make loop to navigate the data
    }
