I have a dilemma about what is the best (and correct) approach if I want to disable form controls (or at least make them unavailable for user interaction) during a period of time when user clicks sort of "Save" or "Submit" button and data travelling over the wire. I don't want to use JQuery (which is evil!!!) and query all elements as array (by class or attribute marker) The ideas I had so far are:
如果我想在用户单击某种“保存”或“提交”按钮并在网络上传输数据时禁用表单控件(或至少使它们不能用于用户交互),我就会陷入两难境地。我不想使用JQuery(这是邪恶的!!!)并将所有元素查询为数组(按类或属性标记),我到目前为止的想法是:
- Mark all elements with
cm-form-control
custom directive which will subscribe for 2 notifications: "data-sent" and "data-processed". Then custom code is responsible for pushing second notification or resolve a promise. - 用cm-form-control自定义指令标记所有元素,该指令将订阅两个通知:“数据发送”和“数据处理”。然后自定义代码负责推送第二次通知或解决一个承诺。
- Use
promiseTracker
that (unfortunatelly!) enforces to produce extremely stupid code likeng-show="loadingTracker.active()"
. Obviously not all elements haveng-disabled
and I don't want to userng-hide/show
to avoid "dancing" buttons. - 使用promiseTracker(不幸的是!)生成极其愚蠢的代码,比如ng-show=“loadingTracker.active()”。显然,并不是所有元素都禁用了ng,我不想使用ng-hide/show来避免“跳舞”按钮。
- Bite a bullet and still use JQuery
- 咬紧牙关,仍然使用JQuery
Does any one have a better idea? Thanks in advance!
有人有更好的主意吗?提前谢谢!
UPDATED: The fieldset idea DOES work. Here is a simple fiddle for those who still want to do the same http://jsfiddle.net/YoMan78/pnQFQ/13/
更新:fieldset思想确实有效。对于那些仍然想要做同样事情的人,这里有一个简单的方法:http://jsfiddle.net/YoMan78/pnQFQ/13/
HTML:
HTML:
<div ng-app="myApp">
<ng-form ng-controller="myCtrl">
Saving: {{isSaving}}
<fieldset ng-disabled="isSaving">
<input type="text" ng-model="btnVal"/>
<input type="button" ng-model="btnVal" value="{{btnVal}}"/>
<button ng-click="save()">Save Me Maybe</button>
</fieldset>
</ng-form>
</div>
and JS:
JS:
var angModule = angular.module("myApp", []);
angModule.controller("myCtrl", function ($scope, $filter, $window, $timeout) {
$scope.isSaving = undefined;
$scope.btnVal = 'Yes';
$scope.save = function()
{
$scope.isSaving = true;
$timeout( function()
{
$scope.isSaving = false;
alert( 'done');
}, 10000);
};
});

Wrap all your fields in fieldset and use ngDisabled directive like this:
在fieldset中包装所有字段,并使用ngDisabled指令如下:
<fieldset ng-disabled="isSaving"> ... inputs ...</fieldset>
It will automatically disable all inputs inside the fieldset.
它将自动禁用fieldset中的所有输入。
Then in controller set $scope.isSaving
to true
before http call and to false
after.
然后在控制器中设置$scope。在http调用之前保存为true,之后保存为false。

There is an simple solution in modern browsers:
现代浏览器有一个简单的解决方案:
-
define a css class
定义一个css类
.disabled { pointer-events: none; ... ... }
-
add this class to
ng-form
将这个类添加到ng-form中
<ng-form data-ng-class="{ 'disabled': isSaving }"> ... inputs ... </ng-form>
Here is the pointer-events support chart.
这是指针事件支持图。
Note: even if you set pointer-events: none
, you can still tab to input element with your keyboard.
注意:即使您设置了指针事件:none,您仍然可以使用键盘选项卡来输入元素。
