动态属性与AngularJS [英] Dynamic Attributes with AngularJS
问题描述
在某些情况下,我需要不同的属性适用于根据我在模特属性的一个节点。
In some cases I need to apply different attributes to a node based on properties in my model.
例如,在一个情况下,我需要添加一个必要的标签,并在另一种情况并非如此。我一直在使用NG-如果有不同的分支来实现这一点,但情况正在迅速失控。
For example, in one case I need to add a 'required' tag and in another case not. I've been using ng-if with different branches to accomplish this but the cases are getting out of hand quickly.
<div ng-if="model.required">
<input class="form-control"
type="text"
required
ng-model="model" />
</div>
<div ng-if="!model.required">
// as different options arise,
// i have more forks for each attribute combo
<input class="form-control"
type="text"
ng-model="model" />
</div>
有动态应用属性节点更好的办法?
Is there a better way to dynamic apply attributes to nodes?
推荐答案
我也很快建立了一个指令,它允许您指定动态属性。
I have quickly created a directive that allows you specify attributes dynamically.

我不知道这是否会收到预期的效果,你在这个简单的表格后,但也可能是一个很好的起点。你基本上是:
I'm not sure if it will have the desired effect you are after in this simple form, but it might be a good starting point. You essentially use:
&LT; DIV DYN-ATTRS =someModelArray&GT;&LT; / DIV&GT;
和相应设置你的模型:
$scope.someModelArray = [
{ attr: 'myattribute', value: '' },
{ attr: 'anotherattribute', value: 'val' }
];
