Question

我需要创建一个通过ajax请求生成的可单击单选按钮的列表。它们将如下所示：

10/15/2018
10/14/2018
10/13/2018
....

所以我正在下面进行Ajax调用并得到结果：

onTabChange: function (tabPanel, tab) {            
    if (tab.getTitle() == 'Reconciliation') {
        Ext.Ajax.request({
            url: '***',
            reader: {
                type: 'json',
                rootProperty: 'data'
            },
            useDefaultXhrHeader: false,
            withCredentials: true,
            scope: this,
            success: function (response) {
                var selectReconciliation = this.lookupReference('lisatradereconciliation');
                // Get the data from Ajax Request and shape it
                var data = Ext.JSON.decode(response.responseText).data;

                var reconciliationItems = [];
                // Put the data into a shape that it will need to look like on the page
                for (var i in data) {
                    reconciliationItems.push("boxLabel: '" + data[i].substr(5, 2) + "/" + data[i].substr(8, 2) + "/" + data[i].substr(0, 4) +"', name: 'rI', inputValue: 'data[i]'");
                }
            },
            failure: function (response) {
                '***'
            }
        });

    }
},

然后我将其发送到如下视图单选项目：

items: [{
    xtype: 'radiogroup',
    fieldLabel: 'day',
    items: reconciliationItems
}]

但这不起作用。

reconciliationItems数组应定义为全局变量，或者在ajax成功处理程序之外，以实现所需的功能：

在success之外定义数组：

window.reconciliationItems = [];

然后像这样在success处理程序中访问它：

success: function (response) {
                var selectReconciliation = this.lookupReference('lisatradereconciliation');
                // Get the data from Ajax Request and shape it
                var data = Ext.JSON.decode(response.responseText).data;

                // var reconciliationItems = []; <-- Dont define here 
                // Put the data into a shape that it will need to look like on the page
                for (var i in data) {
                    reconciliationItems.push("boxLabel: '" + data[i].substr(5, 2) + "/" + data[i].substr(8, 2) + "/" + data[i].substr(0, 4) +"', name: 'rI', inputValue: 'data[i]'");
                }
            },
