从数组的数组动态创建 Kendo 个下拉列表

Question

我有一个存储在变量中的 Web 服务的数组列表。

如果我使用一个数组或 1 个对象的列表，它就可以工作。

如果我使用任何长度超过 1 个数组的列表，只有最后生成的下拉列表有效。数据似乎丢失了，因为我无法单击控件并查看项目。

检查控制台中的对象不显示数据。

Javascript / Jquery 函数如下所示：

for (var i = 0; i < $scope.filters.data.length; i++) {
            var control = $scope.filters.data[i];

            var optionName = control.Name
            if (control.UiType == "SingleSelect") {
                var controlName = "selectFilterFor" + optionName.trim();

                var selectControl = $scope.getSingleSelect(optionName, controlName);

                $(".search-panel-fields")[0].innerHTML += selectControl;

                var selectorName = "#" + controlName;

                //$(controlName).kendoDropDownList().data("kendoDropDownList");

                $(selectorName).kendoDropDownList({
                    dataTextField: "Name",
                    dataValueField: "Value",
                    dataSource: control.Attributes,
                    dataBound: onDataBound,
                    //index: 0,
                    optionLabel: { Name: "", Value: "" }
                });

            }

        }

我认为 DOM 可能太慢了，但添加了 setTimeout(function() {//updateDom }, 1000);没有效果。

我还在 dataBound 事件上添加了一些日志记录，看看它是否一切正常：

dataBound: function (e) {
     console.log('data is bound: ' + control.Name);
     console.log(e.sender.dataItems());
  },

还有带有数据数组的元素。我现在特别要避免额外的网络呼叫。

JSON 数据的快速修改版本：

如何Kendo正确实例化所有对象？

Answer 1

您可能对数组中项目的属性有一些疑问。添加元素的更安全方法是 .appendTo 而不是 innerHTML 连接

根据问题中显示的 'modified data'，以下应构建三个 kendo 下拉菜单。

  response.JSON.forEach (control => 
  { if (control.UIOGLItrol.UiType == "SingleSelect") 
    {
      var controlId = "selectFilterFor" + control.Name;

      $("<input>", {id:controlId, name:control.Name, class:"ssInput", type:"text"})
      .appendTo(".search-panel-fields");

      $("#"+controlId).kendoDropDownList({
        dataTextField: "Name",
        dataValueField: "Value",
        dataSource: control.Attributes,
        dataBound: onDataBound,
        optionLabel: { Name:"", Value:"" }
      });
    }
  });
