有一个简单的问题。
我有一个包含大量字段的表单,可以从UI更新。
我找到了一个名为" ng-model-option"这似乎是处理这些问题。
我的问题是:是否可以在不指定ng-model-options="{ updateOn: 'submit'}"
的情况下回滚整个表单上的更改
在我的表格中的每个输入字段?
或者,此指令在每个字段上查看并仅提交已修改的字段?
提前感谢您的帮助和解释!

您可以将所有字段绑定到单个对象,即
$scope.model = {
foo: '',
bar: '',
etc: ''
};
通过这种方式,您可以存储模型的副本,并在您希望的任何位置重置绑定模型。
例如,在服务调用失败后撤消所有更改:
$scope.submit = function() {
yourService.update(model).then(function(result) {
// handle the success.
}, function(err) {
$scope.model = $scope.originalModel;
});
}
或者重新加载页面是一个选项吗?
$window.location.reload();

我通过使用并将所有内容映射到ng-model-option指令
找到了解决方案<form name="EditUserForm" class="col-md-12 form-horizontal top-buffer">
<div class="form-group">
<div class="col-sm-4 text-right">
<label>User Id:</label>
</div>
<div class="col-sm-8">
<input type="text" class="form-control info-textbox" ng-model="user.UserID" ng-disabled="true" />
</div>
</div>
<div class="form-group">

</div>
<div class="col-sm-8">
<!--<input type="text" class="form-control info-textbox" ng-model="user.Department.DepartmentName" ng-readonly="isReadOnlyMode" />-->
<select class="form-control info-textbox" ng-options="department.DepartmentName for department in departments"
ng-model="selectedDepartment"
ng-readonly="isReadOnlyMode"
ng-model-options="{updateOn: 'submit'}"></select>
</div>
</div>
<div class="form-group">

</div>
<div class="form-group">

<div class="col-sm-8">
<input type="password" class="form-control info-textbox" ng-model="user.Password" ng-readonly="isReadOnlyMode" ng-model-options="{updateOn: 'submit'}" />
</div>
</div>
<!--Buttons-->
<div class="form-group">
<div class="col-sm-4 text-right">
<button type="button" class="btn btn-primary info-button" name="btnEdit" ng-click="flipBetweenEditMode(isReadOnlyMode)" ng-show="isReadOnlyMode">
<span>Edit</span>
</button>
<button type="button" class="btn btn-primary info-button" name="btnEdit" ng-click="flipBetweenEditMode(isReadOnlyMode)" ng-show="!isReadOnlyMode">
<span>Cancel</span>
</button>
</div>
<div class="col-sm-4 text-left">
<button type="submit" class="btn btn-primary info-button" name="btnSave" ng-click="saveChangesToUser(user, isReadOnlyMode)" ng-show="!isReadOnlyMode">
<span>Save</span>
</button>
</div>
<div class="col-sm-4 text-left">
<div back-button></div>
</div>
</div>
</form>
然后是控制器
$scope.flipBetweenEditMode = function (isReadOnlyMode) {
if (!isReadOnlyMode) {
$scope.EditUserForm.$rollbackViewValue();
}
console.log(isReadOnlyMode);
$scope.isReadOnlyMode = !isReadOnlyMode;
};
取消这将回滚所有更改并在第一阶段恢复模型。
