angularjs – 将ngMessages与Angular 1.2一起使用

有谁知道是否有支持ngMessages的Angular 1.2的分支？

我很乐意使用它,但我对IE8有要求.

在此先感谢您的帮助.

解决方法

我已经更新了pleerock的答案,以处理具有for和when等属性的元素指令,例如ngMessages和ngMessage.您可以在此 github repo中找到相同的内容

angular.module('uiMessages',[]).directive('uiMessages',function() {

  return {
    restrict: 'EA',link: function(scope,element,attrs) {
      // hide all message elements
      var messageElements = element.find('ui-message,[ui-message]').css('display','none');
      // watch when messages object change - change display state of the elements
      scope.$watchCollection(attrs.uiMessages || attrs['for'],function(messages) {
        var oneElementAlreadyShowed = false;
        angular.forEach(messageElements,function(messageElement) {
          messageElement = angular.element(messageElement);
          var message = messageElement.attr('ui-message') || messageElement.attr('when');
          if (!oneElementAlreadyShowed && messages[message] && messages[message] === true) {
            messageElement.css('display','block');
            oneElementAlreadyShowed = true;
          } else {
            messageElement.css('display','none');
          }
        });
      });
    }
  };
});
