$render 在 angular 1.2.2 停止工作(文件验证指令) [英] $render stopped working at angular 1.2.2 (file validation directive)

问题描述

昨天我已经从 angular 1.0.8 迁移到了 angular 1.2.2，除了一堆损坏的东西，我已经修复了，以下指令中的 $render 函数不再触发.

以前有人遇到过这种行为吗?0

directive('validFile', function (utils, $filter) {返回 {要求:'ngModel'，链接:函数(范围、el、attrs、ngModel){如果(utils.isMobileAgent())返回;var form = el.parents().find('form');ngModel.$render = 函数 () {调试器；if(form.hasClass('ng-pristine'))返回;if(el.val() && el.val().length > 0){ngModel.$setViewValue(el.val());}if(el.hasClass('ng-invalid')){el.parent().addClass('ng-invalid').addClass('ng-invalid-required');ngModel.$setValidity(attrs.name, false);ngModel.$setPristine(attrs.name, false);scope.fileMsg = $filter('translate')('PLEASESELECT') + ' ' + $filter('translate')(attrs.name);//scope.layout.showFileError = true;}别的{el.parent().removeClass('ng-invalid').removeClass('ng-invalid-required').addClass('ng-valid');ngModel.$setValidity(attrs.name, true);}};el.bind('鼠标悬停', function(){if(form.hasClass('ng-dirty') && el.parent().hasClass('ng-invalid'))el.removeClass('ng-pristine');});el.bind('mouseleave', function(){if(el.val() && el.val().length > 0){el.addClass('ng-pristine');}})el.bind('改变', 函数 () {范围.$应用(函数(){ngModel.$render();});});form.bind('change', function () {范围.$应用(函数(){ngModel.$render();});});}};});

标记:

<input type="file" data-ng-model='model.formData.resume' name="resume" data-valid-file data-my-validate data-value-required="true>

解决方案

将指令的优先级提高到 0 以上.

例如:

myApp.directive('validFile', function ($filter) {返回 {优先级:10，

这是一个我发现与这个ui-tinymce问题相关的问题的详细解释从根本上说，这与您的相同.

简短版本的解释是此更改导致input的 $render 优先于您自己的.通过提高你的指令的优先级，你实际上给了你的 $render 优先级 - 就像在 1.2 rc3 中的改变之前一样.

I have migrated from angular 1.0.8 to angular 1.2.2 yesterday, and beside a bunch of other things that got broken and I've already fixed, the $render function on the following directive is not firing anymore.

Did anyone encouter such a behavior before?0

directive('validFile', function (utils, $filter) {
    return {
        require: 'ngModel',
    link: function (scope, el, attrs, ngModel) {

      if(utils.isMobileAgent())
          return;
      var form = el.parents().find('form');
        ngModel.$render = function () {
          debugger;
          if(form.hasClass('ng-pristine'))
            return;

          if(el.val() && el.val().length > 0){
            ngModel.$setViewValue(el.val());
          }

          if(el.hasClass('ng-invalid')){
            el.parent().addClass('ng-invalid').addClass('ng-invalid-required');
            ngModel.$setValidity(attrs.name, false);
            ngModel.$setPristine(attrs.name, false);
            scope.fileMsg =  $filter('translate')('PLEASESELECT') + ' ' + $filter('translate')(attrs.name);
            // scope.layout.showFileError = true;
          }
          else{
            el.parent().removeClass('ng-invalid').removeClass('ng-invalid-required').addClass('ng-valid');
            ngModel.$setValidity(attrs.name, true);
          }
        };
        el.bind('mouseover', function(){
          if(form.hasClass('ng-dirty') && el.parent().hasClass('ng-invalid'))
          el.removeClass('ng-pristine');
        });
        el.bind('mouseleave', function(){
          if(el.val() && el.val().length > 0){
           el.addClass('ng-pristine');
          }
        })
        el.bind('change', function () {
            scope.$apply(function () {
                ngModel.$render();
            });
        });
        form.bind('change', function () {
            scope.$apply(function () {
                ngModel.$render();
            });
        });
    }
};
});

解决方案

Increase the priority of your directive to something above 0.

For example:

myApp.directive('validFile', function ($filter) {
   return {
     priority: 10,

Here's a detailed explanation of the problem that I found associated with this ui-tinymce issue that's, at it's root, the same as yours.

The short version of the explanation being that this change causes input's $render to take precedence over your own. By bumping the priority of your directive you, in effect, give your $render priority- as it was before that change in 1.2 rc3.
