引用此元件處:
, { xtype: 'panel', style: 'margin-left:50;', layout: 'column', id: 'calendarArea', width: 700, height: 400, border: true, items: [{ layout: 'form', width: '98%', height: '98%', items:[ /** 這裡放置日曆控制元件 */ myDate ] }] }
日曆控制元件最下方有一個確定按鈕,勾選完複選框之後,單擊這個【確定】按鈕,會返回給頁面一個數組dateArray,其格式如下:
",,,,,2013-05-31,2013-06-01,,,,,,,,,,,,2013-06-13,2013-06-14,,,,,,,,,,,,,,2013-06-28,2013-06-29,2013-06-30,2013-07-01";
if(dateArray != null && dateArray != "") {
content = dateArray.join(','); //陣列的話,不識別,要轉換成字串才可以
}
後臺邏輯中根據具體的業務來對這個字串進行分析即可。
