AngularJS ng-repeat和表单验证

Question

我在AngularJS中使用表单验证并在表单中使用ng-repeat的项目时遇到问题.

HTML:

<div ng-app>
    <div ng-controller="EditController">
        <form name="form" novalidate>Name:
            <br/>
            <input type="text" ng-model="model.name" required="" />
            <hr />Products:
            <br/>
            <div ng-repeat="product in model.products">
                <div>
                    <input type="text" ng-model="product.name" required="" />
                    <input type="text" ng-model="product.price" required="" /> <a href="javascript:void(0)" ng-click="remove($index)">Remove</a>

                </div>
            </div>
            <hr />
            <button ng-disabled="form.$invalid || !form.$dirty" ng-click="save()">save</button>
            <div ng-show="form.$invalid && !form.$pristine">There are errors.</div>
            <div ng-show="!form.$dirty && form.$pristine">No changed detected to be saved.</div>
            <div>
                <p>Dirty? {{form.$dirty}}</p>
                <p>Invalid? {{form.$invalid}}</p>
                <p>Pristine? {{form.$pristine}}</p>
            </div>
        </form>
    </div>
</div>

JS:

function EditController($scope) {
    $scope.model = {
        name: "Phil",
        products: [{
            name: "Foo",
            price: 12.99
        }, {
            name: "Bar",
            price: 15.99
        }, {
            name: "FooBar",
            price: 24.99
        }]
    };

    $scope.remove = function(index){
      $scope.model.products.splice(index, 1);  
    };

    $scope.save = function () {
        console.log("saved");
    };
}

复制:

单击删除删除1项,窗体不会变脏,因此按钮不启用.

如果编辑名称字段,则表单变脏.

关于如何从数组中删除项目的任何想法都会使表单变脏？

Angular提供了一个$setDirty()功能,仅用于您在此处尝试完成的目的.只需将其添加到您的ng-click属性中即可

<input type="text" ng-model="product.price" required="" /> 
<a href="javascript:void(0)" ng-click="remove($index); form.$setDirty(true);">Remove</a>

我把你的小提琴分开,让它在这里工作
