问题描述
我使用带有语义 UI 的 Angular2 作为 css 库.我有这段代码:
<a class="ui card">... </a><a class="ui card">... </a><a class="ui card">... </a>
卡片渲染得很好,中间有一个空格.像这样:参考链接中的卡片部分
由于卡片代表某种视图,我想用它制作一个组件,所以现在代码是:
<my-card-component></my-card-component><my-card-component></my-card-component><my-card-component></my-card-component>
但现在风格坏了,它们之间没有空间了.
有什么好的方法可以解决这个问题吗?
我想到的第一件事是:
my-card-component 旧模板:<a class="ui card">[一些垃圾]</a>|||VVVmy-card-component 新模板:[一些垃圾]并实例化如下:<my-card-component class="ui card"></my-card-component>或喜欢:<a href="?"我的卡片组件></a>
但这并不令人满意,因为我希望能够传入一个对象并且组件会自动设置[href]=obj.link
.
在 AngularJS 1.0 中有一个 replace: true
属性,它完全符合我的需要,Angular2 中是否有类似的东西?
Angular2 中没有 replace=true
.它被认为是一个糟糕的解决方案,并且在 Angular 1.x 中也不推荐使用.
另请参阅为什么在 AngularJS 中不推荐使用替换?
在组件或指令中使用属性选择器而不是标签选择器.
只要改变
@Directive({ ..., selector: "my-card-component"})
到
@Directive({ ..., selector: "a[my-card-component]"})
并像使用它一样
... </a>
你也可以调整封装策略http://blog.thoughtram.io/angular/2015/06/29/shadow-dom-strategies-in-angular2.html 但我认为默认的 emulated
应该是你的情况很好.
I'm using Angular2 with Semantic UI as a css library. I have this piece of code:
<div class="ui three stakable cards">
<a class="ui card"> ... </a>
<a class="ui card"> ... </a>
<a class="ui card"> ... </a>
</div>
the cards are rendered nicely with a space between and such.like this: refer to cards section in the link
since the cards represent some kind of view I thought of making a component out of it, so now the code is:
<div class="ui three stakable cards">
<my-card-component></my-card-component>
<my-card-component></my-card-component>
<my-card-component></my-card-component>
</div>
but now the style is broken, there is no space between them anymore.
Is there any nice way of fixing this ?
the first thing I thought of doing is this:
my-card-component OLD template:
<a class="ui card">
[some junk]
</a>
|||
VVV
my-card-component NEW template:
[some junk]
and instantiating like:
<my-card-component class="ui card"></my-card-component>
or like:
<a href="?" my-card-component></a>
but this is not satisfactory since I want to be able to pass in an object and the component would automatically set the [href]=obj.link
.
in AngularJS 1.0 there was a replace: true
property which does excatly what i need, is there a similar thing in Angular2 ?
There is no replace=true
in Angular2. It is considered a bad solution and deprecated in Angular 1.x as well.
See also Why is replace deprecated in AngularJS?
Use an attribute-selector instead of a tag-selector in your component or directive.
Just change
@Directive({ ..., selector: "my-card-component"})
to
@Directive({ ..., selector: "a[my-card-component]"})
and use it like
<a my-card-component class="ui card"> ... </a>
You might also adjust the encapsulation strategy http://blog.thoughtram.io/angular/2015/06/29/shadow-dom-strategies-in-angular2.html but I think the default emulated
should be fine in your case.
