2018-10-24:Ajax完成預約效果
ajax完成預約效果
- 保證瀏覽器訪問action能夠得到json資料集合(檢查瀏覽器輸出)。
- 先做好靜態的表格帶基本的樣式,通過ajax方法,將回撥函式返回的預約資訊,迴圈變成td,組裝到table中,不需要了靜態的tr和td,由於涉及日期處理,需要解決如何獲取當前日期,如何獲取當前日期所在的周次,如何獲得當前日期本週一的日期,通過將日期編號等關鍵資訊生成到td的屬性中,以便匹配(檢查ajax回撥函式返回的內容能否正確生成表頭資訊包括日期和星期幾)。
- 通過本週週一和週五的迴圈內部和返回的資料集遍歷雙重迴圈,找到日期和半天匹配的資訊,通過判斷生成不同的td樣式,顯示不同的介面效果(檢查本週資料是否正確生成)。
- 將生成部分需要封裝的方法提取出來,將原來的程式碼完整剪下 用function封裝,將程式碼中變數不是自己宣告的就需要傳參,在原位置呼叫方法傳參(檢查封裝後已完成功能是否受影響 如本週th,td和下一週th,td逐步封裝)。
- 追加切換按鈕,一定要在ajax回撥函式中呼叫方法追加。(因為ajax 有可能先執行但是後執行完,可能造成需要的資料集還沒有從伺服器取回來),再追加封裝的click方法(檢查按鈕能不能點,點了能不能切換本週和下一週)。
- 通過點選時間和本td屬性中儲存的日期和上下午,和資料集合比對找到需要的其他資料,新增的公共的div用於顯示(公共div需要定位和父元素偏移,檢查先不隱藏公共的div,調整完畢才隱藏)。
