是否可以使用不同的占位符进行掩码输入？

Since my form has no labels, I would like to be able to use a different placeholder with Angular and Angular-UI-Utils-Mask:

由于我的表单没有标签,我希望能够使用与Angular和Angular-UI-Utils-Mask不同的占位符:

<div ng-controller="myController">
    <input type="text"
        ng-model="date"
        ui-mask="99/99/9999"
        placeholder="Birth Date"/>  
</div>

Using jquery-inputmask it works like a charm, but I had too many problems to make it work with Angular so I'm now trying to go Angular way, but Angular shows my input as:

使用jquery-inputmask它就像一个魅力,但我有太多的问题使它与Angular一起使用所以我现在尝试去Angular方式,但是Angular将我的输入显示为:

Bi/th/Date

Here's a fiddle to show it: http://jsfiddle.net/XS4R6/

这是一个显示它的小提琴:http://jsfiddle.net/XS4R6/

I also saw some people talking about ´ui-mask-placeholder´, but it does nothing.

我也看到一些人在谈论'u-mask-placeholder',但它什么也没做。

Is there a way to accomplish this?

有办法实现这个目标吗?

EDIT

To clarify, I think it's just fine to use just placeholders since you also use titles (hint) so people always know what are they supposed to type in those inputs:

为了澄清,我认为只使用占位符就好了,因为你也使用了标题(提示),所以人们总是知道他们应该在这些输入中键入什么:

The input showing __.___.___ is the one I'm using Angular UI Mask.

显示__.___.___的输入是我正在使用Angular UI Mask的输入。

JQuery Inputmask works very fine, since it shows the 'name' placeholder and as soon as I mouse over or click the input it shows the mask.

JQuery Inputmask工作得非常好,因为它显示了'name'占位符,只要我鼠标悬停或单击输入它就会显示掩码。

I'm thinking you can use another tag to simulate placeholder, maybe the code here is not very good, but I just provide another thought.

我想你可以使用另一个标签来模拟占位符,也许这里的代码不是很好,但我只是提供了另一个想法。

app.directive("myPlaceholder", ['$compile', function($compile){
return {
    restrict: 'A',
    link: function(scope, elem, attr) {
        attr.$observe('myPlaceholder', initialize);
        var mask = '__/__/____';

        function initialize(value) {
            // label is not clickable in IE, that's the reason why we use span tag
            var fakePlaceholder = angular.element('<span class="placeholder">' + value + '</span>');
            // click placeholder to focus the input
            fakePlaceholder.on('click', function(){
                elem.focus();
            });
            elem.before(fakePlaceholder);
            $compile(fakePlaceholder)(scope);

            elem.on('focus', function() {
                fakePlaceholder.hide();
            }).on('blur', function() {
                if (elem.val() === mask) {
                    fakePlaceholder.show();
                }
            });
        }
    }
};
}]);
