自定义AngularJS指令名称中包含破折号不起作用

问题描述

我编写了以下Angular指令，该指令将向所有子代添加必需"属性:

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);
    }
  }
});

我真的很想称它为"require-all"，但如果我重命名，它将无法正常工作.为什么"requireall"有效，而不是"require-all"?

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，因此您的requireall指令需要重命名为requireAll，然后可以在标记中使用require-all(或data-require-all(如果要正确标记自定义标签).一开始让我困惑了.

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.
