Question

我在事件中有这个js代码：

var userData = tableWidget.grid('userData');
console.log(tableWidget.grid('userData'));
$.ajax({
    "url": "../../server/query.aspx?tableEvent=reordercolumns&table=SubContractor",
    "data": { dataColumnOrder: JSON.stringify(userData) },
    "dataType": "json",
    "type": "GET",
    "error": function () {
        console.log("Something wrong with the columns' reorder saving process");
    }
});

让我们说userData有两个条件。事件发生之前和之后：

userData before event：[a, b, c]

userData after event：[a, c, b]

就我而言，当事件被触发时，console.log(tableWidget.grid('userData'));包含应有的userData after event。但是，当我通过ajax发送它时，在服务器中，该对象包含userData before event。我假设ajax在对象完全更新之前发送对象。

我的问题是，ajax完全更新后有没有办法执行var userData = tableWidget.grid('userData');？

已更新：事实证明问题似乎发生在stringify函数中。以下是包含和不包含stringify的对象的屏幕截图：

没有字符串console.log(userData);：

使用Stringify console.log(JSON.stringify(userData));：

            "widthLargeDesktop": 90
        }
    ]
}

正如您所看到的那样，使用stringify不会改变列的顺序。

我想你必须尝试这样......

  var userData = tableWidget.grid('userData');
console.log(tableWidget.grid('userData'));
$.ajax({
    url: "../../server/query.aspx?tableEvent=reordercolumns&table=SubContractor",
    data: { 'dataColumnOrder': userData},
    dataType: "json",
    type: "POST",
    success:function(response){
      //write JS when ajax call success
      console.log('success');
    },
    error: function () {
        console.log("Something wrong with the columns' reorder saving process");
    }
});

完全更新对象后如何通过ajax发送对象？
