我正在尝试在刷新数据后将更改应用于ui网格，但收到此错误：
angular.js:13236 Error: [$rootScope:inprog] $apply already in progress
http://errors.angularjs.org/1.5.0/$rootScope/inprog?p0=%24apply

at callback (angular.js:24546)

有什么不对？我的代码在下面
获取数据
var initialData = []
var getData = function (castomUrl) {
$http.get(castomUrl)
.success(function (data) {
// console.log(data)
// Considering Angular UI-Grid, the data should be declared inside as scope var and put it inside gridOptions
$scope.initialData = data;
// $scope.gridOptions.data = $scope.initialData;
// ***
angular.forEach($scope.initialData, function (val) {
val.occuredDate = new Date(val.occuredDate);
});
// $interval whilst we wait for the grid to digest the data we just gave it
$interval(function () {
$scope.gridApi.selection.selectRow($scope.initialData[0]);
}, 0, 1);
});
};
getData(urlData);
点击
获取行值 gridApi.selection.on.rowSelectionChanged($scope, function (row) {
// api call to get row Data and update for current row
var dataRow = row.entity;
$scope.id = dataRow.id;
$scope.getRowData();
});
$scope.getRowData = function(){
eventService.singleEvent($scope.id)
.then(function (data) {
$scope.rowData = data.model;
$scope.rowKeys = Object.keys($scope.rowData);
}).then(function () {
$scope.getUpdate();
});
};
其中eventService.singleEvent是
function singleEvent (id) {
return $http.get(apiUrl+id)
.then(function (serviceResp) {
return serviceResp.data;
});
}
以html格式显示行数据
<form style="padding: 15px" ng-submit="submitForm(rowData)">
<div class="form-group row">
<div ng-repeat="(key, value) in rowData">
<div ng-if="(key === 'id' || key.toLowerCase().endsWith('id') === false) ? true : false">
<label for="rowData" class="col-sm-2">{{key | makeUppercase
}}</label>
<div class=" col-sm-2">
<input class="form-control rowValue"
id="rowData[key]"
ng-disabled="disableInput(key)"
ng-if="!isObject(value)"
type="text"
ng-model="rowData[key]"
/>
<input
class="form-control rowValue"
id="rowData[key].name"
ng-disabled="disableInput(key)"
ng-if="isObject(value) && key !== 'status' && key !== 'priority' && key !== 'severity'"
type="text"
ng-model="rowData[key].name"
/>
<select ng-if="isObject(value) && key == 'status'"
ng-model="rowData.statusId"
class="form-control rowValue"
id="statusId"
ng-options='item.id as item.name for item in eventLov.statusOptions()'>
<option value=''>{{value.name}}</option>
</select>
<select ng-if="isObject(value) && key == 'priority'"
ng-model="rowData.priorityId"
class="form-control rowValue"
id="priorityId"
ng-options='item.id as item.name for item in eventLov.priorityOptions()'>
<option value=''>{{value.name}}</option>
</select>
<select ng-if="isObject(value) && key == 'severity'"
ng-model="rowData.severityId"
class="form-control rowValue"
id="severityId"
ng-options='item.id as item.name for item in eventLov.severityOptions()'>
<option value=''>{{value.name}}</option>
</select>
</div>
</div>
</div>
</div>
<button type="submit" class="btn btn-default" ng-if="rowData">Save</button>
<button type="button" class="btn btn-default" ng-if="rowData"
ng-click="cancelForm()">
Cancel
</button>
</form>
提交更改
$scope.submitForm = function (event) {
$scope.modifyEvent(event);
$timeout( function(){
$rootScope.refresh();
}, 100);
};
$scope.modifyEvent = function (event) {
// $log.info(event);
eventService.modifyEvent(event)
};
更新服务
function modifyEvent (event) {
return $http({
method : 'PUT',
url : apiUrl + event.id,
data : event
}, event)
.then(function success (result) {
$log.info("Update Successful");
return result.data;
}, function error( err ) {
$log.error(" update has been failed ", err);
});
}
刷新网格
$rootScope.refresh = function () {
$log.info("fired");
eventService.events();
$scope.$apply();
}
刷新服务
function events () {
return $http.get(apiUrl)
.then(function (serviceResp) {
return serviceResp.data;
});
}
最后我看到了错误
$申请已在进行中
但数据已上传到数据库并已修改。有什么不对？

FIX 1 -
使用
$timeout(function(){
$scope.$apply()
... write your code here
},0)
摘要周期结束后会触发。
FIX 2 -
如果摘要周期正在运行，则 $scope.$$phase将返回true，否则它将无效，因为它不提供任何回调函数。
也不建议使用
答案 1 :(得分：2)
$timeout回调运行：
$timeout( function(){
$rootScope.refresh();
}, 100);
无需在refresh内触发它。它应该是
$rootScope.refresh = function () {
$log.info("fired");
eventService.events();
}
避免$rootScope:inprog错误的方法是要知道哪些代码在摘要周期内运行，哪些代码没有。
答案 2 :(得分：0)
$rootScope.refresh = function () {
$log.info("fired");
eventService.events();
$timeout(function(){
$scope.$apply();
})
}
答案 3 :(得分：0)
因此强制刷新网格并取出错误的唯一方法是删除范围变量并再次设置它，@ whenus表示没有必要触发$ scope。$ apply在刷新函数内部。 我的工作代码看起来像
$rootScope.refresh = function () {
$log.info("fired");
$scope.initialData = [];
getData(urlData);
可能有丑陋的方式，但重复一次只有一种方法如何强制刷新网格。
