我最终通过解决这个问题 NG-风格是这样的：

I ended up solving this problem by using ng-style like this:

标记：

<div custom-directive ng-style="setWidth()"></div>

角：

link: function(scope, elem, attrs) {
  scope.setWidth = function() {
    return { "width": "200px" }
  }
}

纳克风格预计其中有一个关键的CSS样式名称和值作为相应的样式值的对象。这在所有的浏览器。

ng-style expects an object which has a key as the CSS style name and the value as the value for the corresponding style. This works in all browsers.
