名称中包含破折号的自定义 AngularJS 指令不起作用 [英] Custom AngularJS directive including a dash in the name doesn't work

问题描述

我编写了以下 Angular 指令，将必需"属性添加到所有子项:

I've written the following Angular directive that will add the "required" attribute to all children:

.directive("requireall", function($compile) {
  return {
    restrict: 'A', //only want it triggered for attributes
    compile: function(element, scope) {
      // Prevent infinite loop on compile
      element.removeAttr("requireall");

      var allChildren = element.find('*');
      allChildren.attr('required', 'required');
      $compile(element)(scope);
    }
  }
});

我真的想称它为require-all"，但如果我重命名它，它就不再起作用了.为什么requireall"有效，但require-all"无效?

I really want to call it "require-all" but if I rename it then it doesn't work anymore. Why is "requireall" working but not "require-all"?

推荐答案

Angular 将camelCasing 转换为snake-casing，所以你的requireall 指令需要重命名为requireAll，然后你就可以使用require-all 在你的标记中(或者 data-require-all 如果你想正确标记自定义标签).一开始让我困惑了一段时间.

Angular converts camelCasing to snake-casing, so your requireall directive needs to be renamed to requireAll, then you can use require-all in your markup (or data-require-all if you want to correctly markup custom tags). Confused me for a while at first.
