jQuery Mobile：動態表單創建顯示本機控件與jQuery Mobile插件控件
[英]jQuery Mobile : Dynamic form creation shows native controls v/s jQuery Mobile plugin controls
問題描述
我創建了此測試頁，以了解我遇到的問題。
第一次單擊“表單”選項卡時，瀏覽器顯示jQuery Mobile復選框。 然后，如果我單擊“主頁”選項卡，再單擊“表單”選項卡，它將顯示瀏覽器的本機復選框！
我在這里做錯了什么？ 如何解決？
提前致謝！

您包括一堆資產。 您需要在jQuery Mobile 1.0.1和1.1.0之間做出選擇（當前包括1.1.0 CSS和1.0.1 JS）。
對於jQuery Mobile 1.1.0，您的include應該看起來像這樣：
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.1.0/jquery.mobile-1.1.0.min.css" />
<script src="http://code.jquery.com/jquery-1.6.4.min.js"></script>
<script src="http://code.jquery.com/mobile/1.1.0/jquery.mobile-1.1.0.min.js"></script>
對於jQuery Mobile 1.0.1，您的include應該看起來像這樣：
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.0.1/jquery.mobile-1.0.1.min.css" />
<script src="http://code.jquery.com/jquery-1.6.4.min.js"></script>
<script src="http://code.jquery.com/mobile/1.0.1/jquery.mobile-1.0.1.min.js"></script>
由於您的代碼包含jQuery Mobile 1.0.1，因此應包含jQuery Core 1.6.4。
我不相信這會解決您的問題。 因此，請確保檢查您的JS控制台是否發生任何錯誤。 如果您在初始化jQuery Mobile小部件后嘗試對其進行初始化，則會收到錯誤消息。
