推荐答案

要求您的指令中使用ngModel.

directives.directive("contenteditable", function () {
    return {
        require: 'ngModel',
        link: function(scope, element, attrs, ngModel) {

          function read() {
            ngModel.$setViewValue(element.html());
          }

          ngModel.$render = function() {
            element.html(ngModel.$viewValue || "");
          };

          element.bind("blur keyup change", function() {
            scope.$apply(read);
          });
        }
    }
}
