我在 AngularJS 中的表单验证和在表单中使用 ng-repeat 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:
通过单击删除删除 1 项,表单不会变脏,因此按钮不会启用。
如果您编辑名称字段,则表单会变脏。
关于如何从数组中删除项目使表单变脏的任何想法?
