ExtJs4.2 日期控件datefield周一到周日出现yyyy这样的bug怎么解决

话不多说，直接把ext-lang-zh_CN.js中的这段代码的【dayNames: Ext.Date.dayNames】改成【dayNames: [“日”,“一”,“二”,“三”,“四”,“五”,“六”]】即可；

Ext.define("Ext.locale.zh_CN.picker.Date", {
    override: "Ext.picker.Date",
    todayText: "今天",
    minText: "日期必须大于最小允许日期",
    //update
    maxText: "日期必须小于最大允许日期",
    //update
    disabledDaysText: "",
    disabledDatesText: "",
    monthNames: Ext.Date.monthNames,
    //dayNames: Ext.Date.dayNames,
    dayNames: ["日","一","二","三","四","五","六"],//【就是它】
    nextText: '下个月 (Ctrl+Right)',
    prevText: '上个月 (Ctrl+Left)',
    monthYearText: '选择一个月 (Control+Up/Down 来改变年份)',
    //update
    todayTip: "{0} (空格键选择)",
    format: "y年m月d日",
    ariaTitle: '{0}',
    ariaTitleDateFormat: 'Y\u5e74m\u6708d\u65e5',
    longDayFormat: 'Y\u5e74m\u6708d\u65e5',
    monthYearFormat: 'Y\u5e74m\u6708',
    getDayInitial: function (value) {
        // Grab the last character
        return value.substr(value.length - 1);
    }
});
