加载Winjs.ui.listview时，在页面顶部显示进度条

Question

如何在Winjs.UI.ListView获取数据时在页面顶部显示不确定的进度条。是否有内置功能来显示Winjs的进度？

Answer 1

假设您获取日期的方法是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>
