問題描述
我的 jQuery Mobile 應用程序由一個 index.html 頁面組成，并且只包含一個在啟動時帶有鏈接的頁面:
<div data-role="page"><div data-role="內容"><a id="startPageLink" href="startPage">開始</a></div></div>當用戶點擊開始鏈接時，我想從我的 JSON api 異步加載 startPage 的內容.在回調中，我想通過 JavaScript 為 startPage 創建所有必需的 DOM 元素并將內容添加到其中.我為此創建了一個 createStartPage(data) 方法.
實現這種動態創建的頁面的正確方法是什么，以便打開 index.html#startPage 也有效?我認為應該有一種方法可以連接到 $.mobile.changePage() 以包含自定義加載/頁面創建代碼，但我沒有找到任何東西.或者有沒有更好的辦法解決這個問題?
我有一些時間來解決這個問題，我找到了一個可行的解決方案(經過測試).
一些注意事項:
- 封裝在$(document).ready()中的javascript；用于在用戶導航到帶有哈希標記的 index.html 文件時動態創建頁面(即 index.html#some_hash_mark).
- 函數 create_page(page_id) 用于從鏈接創建頁面(或以編程方式，如果您愿意).
- 請注意，jquery 核心腳本和 jquery mobile css 在 $(document).ready() 語句之前加載，但 jquery mobile 腳本在之后加載.
- 查看 body 標記已被賦予一個 id，該 id 在向其附加頁面時被引用.
文檔示例
My jQuery Mobile app consists of a single index.html page and contains only one page with a link on startup:
<div data-role="page">
<div data-role="content">
<a id="startPageLink" href="startPage">start</a>
</div>
</div>
When the user clicks on the start link, I want to load the content for the startPage from my JSON api asynchronously. On the callback I would like to create all the required DOM elements for startPage via JavaScript and add the content to it. I have created a createStartPage(data) method for this.
What is the right way to implement such dynamically created pages, so that opening index.html#startPage also works? I think there should be a way to hook into $.mobile.changePage() to include custom loading/page-creation code, but I did not find anything. Or is there a better solution for this problem?
解決方案 I had some time to mess around with this and I've found a solution that works (tested).
SOME NOTES:
- the javascript encapsulated in $(document).ready(); is for dynamically creating a page if the user navigates to your index.html file with a hash mark already appended (i.e. index.html#some_hash_mark).
- The function, create_page(page_id) is for creating a page from a link (or programatically if you like).
- Note that the jquery core script and the jquery mobile css are loaded before the $(document).ready() statement but that the jquery mobile script is loaded after.
- See that the body tag has been given an id that is refrenced when appending pages to it.
