问题描述
我正在使用AngularJS。我在控制器中有一个函数,它从服务器获取 .json
文件,处理数据并将其存储在 $ scope
。
所以基本上这个函数在页面加载时需要最多的时间。
所以我有这样的东西,我的页面已经加载但是我的表(用 ng-repeat
填充)没有。加载表格需要几秒钟的时间。在表格加载过程中,我想添加如下进度圈:
在AngularJS中做什么适当的方法?
以下是一个控制器演示:
var serverData = $ http.get('data / topCarObj。 JSON');
函数sortCars(){
angular.forEach($ scope.tabArray,function(tab){
serverData.success(function(data){
angular.forEach(data,函数(键){
....
返回myCarList;
});
});
});
>
$ scope.getData = function(){//在函数中包装获取数据的数据
$ scope.loading = true ; //定义一个指示加载状态的变量// true在这里
$ http.get('path_to_json')。success(function(data){//获取数据
$ scope.loading = false ; //加载完成后,加载= false
})
.error(function(data,status){
$ scope.loading = false; // loading = false when there错误
});
}
$ scope.getData(); //调用函数获取数据
在视图中:
< img src =loading.gifng-show =loading/> //当`$ scope.loading`变量为`true`时显示loading.gif
I am using AngularJS. I have a function in my controller that gets .json
file from the server, working with data and store it in $scope
.
So basically this function needs biggest amount of time when the page is loading.
So I have something like this, my page has loaded but but my table (that populates with ng-repeat
) has not. It takes few seconds to load the table. And while the table is loading I want to add progress circle like that:
What is appropriate way to do it in AngularJS?
Here is a controller demo:
var serverData = $http.get('data/topCarObj.json');
function sortCars(){
angular.forEach($scope.tabArray, function(tab){
serverData.success(function(data){
angular.forEach(data, function(key){
....
return myCarList;
});
});
});
}
In Controller:
$scope.getData = function() { // wrap a data getting code in a function
$scope.loading = true; // define a variable that indicate the loading status // true here
$http.get('path_to_json').success(function (data) { // get the data
$scope.loading = false; // loading is finished so loading = false
})
.error(function (data, status) {
$scope.loading = false; // loading = false when there is a error
});
}
$scope.getData(); // call the function to get data
In View:
<img src="loading.gif" ng-show="loading" /> // show the loading.gif when `$scope.loading` variable is `true`
