我在 extjs 7.2 中有一个网格，其中有一个按日期过滤的商店。我有一个开始日期和一个结束日期，它们绑定到我的 ViewModel 中的日期对象。初始化网格时，第一个字段 (start_date) 的日期显示在字段中，但随后程序从日期字段中引发类型错误。
未捕获的类型错误：j[d] 不是函数

这是带有绑定的网格的 js 类：
Ext.define(K.maintenance.classes.grid, {
extend: K.shared.classes.groupedGrid,
controller: K.maintenance.aliases.controller,
viewModel: K.maintenance.aliases.viewmodel,
requires: ['Ext.data.validator.Date'],
xtype: K.maintenance.xtypes.grid,
bind: '{store}',
tbar: {
xtype:'toolbar',
items: [
{
reference: 'print',
iconCls:'icons-print',
},
'->','Start date : ',
{
xtype: 'datefield',
reference: 'start_date',
vtype: 'daterange',
format: 'Y-m-d',
bind: {
value: '{startDate}',
maxDate: '{endDate}'
},
validators: 'date'
},'-','Stop date : ',
{
xtype: 'datefield',
reference: 'stop_date',
vtype: 'daterange',
format: 'Y-m-d',
bind: {
value: '{endDate}',
minDate: '{startDate}'
},
validators: 'date'
}
]
},
columns: {...}
viewConfig: {
forceFit:true,
scrollToTop: Ext.emptyFn,
scrollOffset: 19,
stripeRows: true
},
stateful: false,
stateId: 'tool_maintenance_status',
animCollapse: false,
});
任何帮助弄清楚为什么会抛出该错误将不胜感激。
