在Jade / Pug中应用属性的嵌套对象 [英] Applying nested object of attributes in Jade/Pug

问题描述

有没有办法将data / aria属性的对象传递给元素？

Is there a way to pass an object of data/aria attributes to an element?

我试过：

div(data={foo:'bar'})

div(data={foo='bar'})

div&attributes({aria:{foo:'bar'}})

但是这些都不会输出所需的属性表示法。第一个和第三个位置是基础数据/ aria属性中的对象文字。第二个是语法错误。

But none of these output the desired attribute notation. The first and third place an object literal in the base data/aria attribute. The second is a syntax error.

我能找到这项工作的唯一方法是：

The only ways that I can find that work are:

div(data-foo='bar')

div&attributes({'aria-foo':'bar'})

推荐答案

引导新行减去 - 您可以在JADE / PUG中编写常规JavaScript。这为你提供了一个强大的武器来解决几乎所有问题。

By leading new lines with a minus - you are able to write regular JavaScript in JADE / PUG. This gives you a powerfull weapon to resolve almost everything.

只需抓住一个常规对象，如 var attributes = {'foo'：'bar'， 'bar'：'foo'} 并使用您想要的前缀为每个循环扩展它的键。

Just grab an regular object like var attributes = {'foo':'bar', 'bar':'foo'} and extend the keys of it in a for each loop with your desired prefix.

这是一支工作笔 http：// codepen .io / pure180 / pen / kXwqdA 和
这可能是您的代码：

Here is a working Pen http://codepen.io/pure180/pen/kXwqdA and this could be your code:

- var attributes = {'foo':'bar', 'bar':'baz'}
- var ariaAttributes = {}
- for (attr in attributes) {
-     var key = 'aria-' + attr
-     ariaAttributes[key] = attributes[attr]
- }

div&attributes(ariaAttributes) Test

您还可以将它用作全局混合，这里是Pen http://codepen.io/pure180/pen/KrqYpB 它看起来像这样：

You can also use it as an global mixin, here is the Pen http://codepen.io/pure180/pen/KrqYpB and it can looks then like this:

mixin setAriaAttr(object)
  - var attributes = object
  - var ariaAttributes = {}
  - for (attr in attributes) {
  -     var key = 'aria-' + attr
  -     ariaAttributes[key] = attributes[attr]
  - }

  div&attributes(ariaAttributes) Test

- var aria = {'foo':'bar', 'bar':'baz'}
+setAriaAttr(aria)
