extjs - 在 ExtJS MVC 中使用 init 函数将数据加载到 Ext.data.Store

Question

我需要在 init 上使用像这样的函数填充 Store 数据:

Ext.define('Vcs.store.Years', {

    extend: 'Ext.data.Store',
    fields: ['year'],
    data: this.getYears(),
    getYears: function() {
        var data = []
            date = new Date
            thisYear = date.getFullYear();
        for(var i = thisYear - 100; i <= thisYear; i++) {
            data.push({
            year: i,
            });
        }
        return data;
    }
});

此代码给出错误:Object [object global] has no method 'generateYears'

你可以这样做:

Ext.define('Vcs.store.Years', {  
    extend: 'Ext.data.Store',
    fields: ['year'],
    data: (function() {
        var data = [],
            date = new Date,
            thisYear = date.getFullYear();
        for(var i = thisYear - 100; i <= thisYear; i++) {
            data.push({
            year: i
            });
        }
        return data;
    })()
});
