windows-8 - Winjs.ui.listview 加载时在页面顶部显示进度条

Question

Winjs.UI.ListView 获取数据时如何在页面顶部显示不确定的进度条。是否有任何内置功能可以显示 Winjs 的进度？

Answer 1

假设您获取 daya 的方法是getData().

function getData(){
var progress = document.createElement("progress");
document.getElementById("someDiv").appendChild(progress); //we have created and appended an undetermined progress bar.
//do the data fetching, and, when it's over and ítems have been asigned to the ListView remove the progress element from the div.
}

否则，在 HTML 中：

<progress></progress>
