How To Refresh Ng-repeat With AngularJs
提问by Md Samir
I am creating a table with few data. I don't want to load all the data at once. So I create a button on view when the user click that buttoon then it hit the server and take the next 4 datasets. At one time only 4 data will.
我正在创建一个数据很少的表。我不想一次加载所有数据。因此，当用户单击该按钮时，我会在视图上创建一个按钮，然后它会访问服务器并获取接下来的 4 个数据集。一次只有 4 个数据会。
<div class="container" ng-controller="paginateEmail" >
<div class="row" >
<div class="panel panel-primary">
<div class="panel-heading">
<h3 class="panel-title">Fail Agent</h3>
</div>
<table class="table">
<thead>
<th>
Email
</th>
</thead>
<tbody>
<tr ng-repeat="item in email1.emailList3">
<td>
{{item}}
</td>
</tr>
</tbody>
</table>
<td>
<form ng-controller="paginateEmail" ng-submit="submitForm()">
<button class="btn btn-default" type="submit">Previous</button> <button type="submit" class="btn btn-default">Next</button>
</form>
</td>
</div>
</div>
</div>
and controller code is -
和控制器代码是 -
basicInfo.controller("paginateEmail", function ($scope, $http) {
$scope.email1 = {
emailList3: []
};
var current=1
$scope.submitForm = function () {
$scope.email1.emailList3.length=0;
$http({method: 'GET', url: "../Dashboard/failAgentsList?current="+current}).
success(function (data) {
var i = 0;
for(i=0;i<data.list.length;i++){
$scope.email1.emailList3.push(data.list[i]);
}
current+=1
});
console.log(current)
}
$scope.submitForm();
}
);
after that the data is successfully binded with the scope.email1.emailList3 but the view is not refreshed. I want that after clicking the next button the view is also refreshed with new data which were bind by the loop in controller.
之后，数据与 scope.email1.emailList3 成功绑定，但视图未刷新。我希望在单击下一个按钮后，视图也会用控制器中的循环绑定的新数据刷新。
Thanks in advance.
提前致谢。

For this problem you can add setTimeout but it is not the correct way to do this because, some times the server take more time to fetch data.
对于这个问题，您可以添加 setTimeout ，但这不是正确的方法，因为有时服务器需要更多时间来获取数据。
setTimeout(function () {
$scope.email1.length = 0;
$http({method: 'GET', url: '../Dashboard/confirmAgentList'}).
success(function (data) {
var i = 0;
for (i = 0; i < data.confAgentList.length; i++) {
$scope.email1.push(data.confAgentList[i]);
}
//and write you additional logic here
}
})
}, 500);

You need to start a digest cycle to have it update the view. Inside your success method use the $apply method:
您需要启动一个摘要循环以使其更新视图。在您的成功方法中使用 $apply 方法：
success(function (data) {
var i = 0;
for(i=0;i<data.list.length;i++){
$scope.email1.emailList3.push(data.list[i]);
}
$rootScope.$apply();
current+=1
});
