我正在研究一個應用程序,讓我們的安全調度員更新包含當前道路和校園條件的頁面。後端是的NodeJS /快遞堆棧和數據是一個簡單的JSON結構看起來是這樣的:Backbone? Can.js?貧民窟DIY?我應該如何處理這些數據?

我不知道這個數據在客戶端工作的最好的辦法是什麼(例如在調度員用來更新數據的頁面上)。該頁面是選擇(校園,道路等條件),TinyMCE textareas(公告和邊欄)和文本輸入(鏈接)的混合。如有必要,我願意改變這種數據結構,但在我看來工作得很好。我一直在看Backbone和Can.JS,但我不確定這些是否適合這一點。
一些額外的信息:
- 沒有必要來更新數據結構separatly中的個別項目;我計劃在保存後發佈整個結構。這就是說...
- 實際上有兩種不同的觀點,一個是調度員,另一個是他們的主管。調度員只能通過下拉菜單改變校園,道路等條件,而且只能改變「條件」鍵;每種可能的情況都有一個默認狀態分配給它。主管可以覆蓋默認狀態,並可以訪問公告,邊欄和鏈接鍵。也許我確實需要重新考慮以前關於一次性發布整個事情的觀點?
- 主管需要能夠添加和刪除鏈接,以及添加和刪除整個鏈接類別。這意味着需要添加和刪除DOM元素,這就是爲什麼我想要使用Backbone或Can.js之類的東西,而不是寫一些貧民區解決方案來查看所有表單元素並生成相應的JSON以POST服務器。
意見建議歡迎!
