Ext 时间控件

我有这样一个需求，就是报表类型分为日报和周报，现在我想解决的是一个周报的问题，因为周报的时间为一整周一整周的，所以在想在datefield时间控件内设置格式为只能选择周，如

我想打开这个控件后就只有最左边的周日和最后边的周六能够选择，其余的都处于不可选状态，就是灰色的。有没有这种解决方案，希望大家提出意见，谢谢。我没有提问的分了，不能追加了，望大家多包涵。

disabledDays : Array

An array of days to disable, 0 based (defaults to null). Some examples:

// disable Sunday and Saturday:
disabledDays: [0, 6]
// disable weekdays:
disabledDays: [1,2,3,4,5]

disabledDates : Array

An array of "dates" to disable, as strings. These strings will be used to build a dynamic regular expression so they are very powerful. Some examples:

// disable these exact dates:
disabledDates: ["03/08/2003", "09/16/2003"]
// disable these days for every year:
disabledDates: ["03/08", "09/16"]
// only match the beginning (useful if you are using short years):
disabledDates: ["^03/08"]
// disable every day in March 2006:
disabledDates: ["03/../2006"]
// disable every day in every March:
disabledDates: ["^03"]

ext的日期选择空间已经支持了。仔细去研究它的api吧

不好意思，我就不翻译了。从字面都很好理解了
