如何禁用saveRow事件ui-grid

I am using ui-grid to display my table in UI. I have a requirement where I don't want table to auto-save the data. I want user to edit all data in a table and click a button to update all the edited data.

我正在使用ui-grid在UI中显示我的表。我有一个要求，我不希望表自动保存数据。我希望用户编辑表格中的所有数据，然后单击按钮更新所有编辑的数据。

Above behavioud is working fine but only problem what I am getting is whenever a user edits a cell in a row, after few seconds, that cell becomes grey and uneditable. On browser cnsole I am getting this error:

上面的行为工作正常，但只有我得到的问题是每当用户在一行中编辑一个单元格，几秒钟后，该单元格变为灰色且不可编辑。在浏览器cnsole上我收到此错误：

A promise was not returned when saveRow event was raised, either nobody is listening to event, or event handler did not return a promise

引发saveRow事件时没有返回promise，无论是没有人正在侦听事件，还是事件处理程序没有返回promise

Because of above JS error, whole row becomes un-editable. How to tell ui-grid to don't save the data unless I click my button.

由于上面的JS错误，整行变得不可编辑。除非我点击我的按钮，否则如何告诉ui-grid不保存数据。

If I handle saveRow event then my button is not working. Please help me in this regard.

如果我处理saveRow事件，那么我的按钮不起作用。请帮助我这方面。

Set "rowEditWaitInterval :-1" in your grid options and it will never call saveRow method by default , so you can save modified data in your custom method. And you can access dirtyrows like this

在网格选项中设置“rowEditWaitInterval：-1”，默认情况下它永远不会调用saveRow方法，因此您可以在自定义方法中保存修改后的数据。你可以访问这样的污垢

var dirtyRows = $scope.gridApi.rowEdit.getDirtyRows($scope.gridApi.grid);

@Jha : Have a look on below url where I have just added fake save method, which will not save any data until you will define your save function inside it. http://plnkr.co/edit/T0TLGLpLsk25vY6SUnzR?p=preview

@Jha：看看下面的url，我刚刚添加了假保存方法，除非你在其中定义你的保存功能，否则不会保存任何数据。 http://plnkr.co/edit/T0TLGLpLsk25vY6SUnzR?p=preview

// Save each row data

//保存每一行数据

gridApi.rowEdit.on.saveRow($scope, $scope.saveRow);
$scope.saveRow = function (rowEntity) {
        var promise = $q.defer();
        $scope.gridApi.rowEdit.setSavePromise(rowEntity, promise.promise);
        promise.resolve();
    };

The above code will resolve your error"A promise was not returned when saveRow event was raised, either nobody is listening to event, or event handler did not return a promise". Do not forget to add "$q" in controller function. I hope your save function will also work properly.

上面的代码将解决您的错误“在引发saveRow事件时没有返回承诺，没有人正在侦听事件，或者事件处理程序没有返回承诺”。不要忘记在控制器功能中添加“$ q”。我希望你的保存功能也能正常工作。
