显示功能,同时从数据库获取数据的进度 [英] showing progressbar while function fetching data from database
问题描述
我对这个按钮,点击一个按钮,我调用一个函数例如
I have a button on this button click I am calling a function e.g
<button ng-Click="getData()"></button>
<div class="Progressbar" ng-show=" showProgress "></div>
控制器:
$scope.showProgress = false;
$scope.getData = function () {
$scope.showProgress = !$scope.showProgress;
myRepository.getAllData();
}
此功能正在较长的时间从数据库中获取数据。结果
我想说明一个微调,而数据也越来越牵强。
This function is taking longer time to fetch data from Database.
I want to show a SPINNER while data is getting fetched.
但这个格显示全功能已经完成之后。
我希望它的功能完成之前显示。
我怎样才能做到这一点?
But this "Div" is shown only after whole function has been completed. I want it to be shown before the completion of function. How I can achieve that?
推荐答案
设置 showProgress = TRUE
加载数据前,和假
一旦数据被加载。对于可靠的行为让 myRepository.getAllData code>回报的承诺,然后用它的
然后
方法来隐藏微调:
Set showProgress = true
before loading data, and to false
once data is loaded. For reliable behavior make myRepository.getAllData
return promise, and then use its then
method to hide spinner:
$scope.getData = function() {
$scope.showProgress = true;
myRepository.getAllData().then(function() {
$scope.showProgress = false;
});
}
