Angularjs 在我的指令中有一个作用域。$apply（函数（）在Angular 1.2.2中被调用，但在Angular 1.2.7中没有调用

我有以下指示：

app.directive('pagedownAdmin', function ($compile) {
    var nextId = 0;
    var markdownConverter = new Markdown.Converter();
    var converter1 = Markdown.getSanitizingConverter();

    converter1.hooks.chain("preBlockGamut", function (text, rbg) {
        return text.replace(/^ {0,3}""" *\n((?:.*?\n)+?) {0,3}""" *$/gm, function (whole, inner) {
            return "<blockquote>" + rbg(inner) + "</blockquote>\n";
        });
    });

    return {
        require: 'ngModel',
        replace: true,
        scope: {
            modal: '=modal',
            ngModel: '=',
            pid: '=pid'
        },
        template: '<div class="pagedown-bootstrap-editor"></div>',
        link: function (scope, element, attrs, ngModel) {

            var editorUniqueId;

            if (attrs.id == null) {
                editorUniqueId = nextId++;
            } else {
                editorUniqueId = attrs.id;
            }

            var template = '<div>' +
            '<div class="wmd-panel">' +
            '<div data-ng-hide="modal.wmdPreview == true" id="wmd-button-bar-' + editorUniqueId + '"></div>' +
            '<textarea data-ng-hide="modal.wmdPreview == true" class="wmd-input" id="wmd-input-' + editorUniqueId + '">' +
            '</textarea>' +
            '</div>' +
            '<div data-ng-show="modal.wmdPreview == true" id="wmd-preview-' + editorUniqueId + '" class="pagedown-preview wmd-panel wmd-preview">test div</div>' +
            '</div>';

            element.html($compile(template)(scope));

            var converter = new Markdown.Converter();

            var help = function () {
                var rawContent = $wmdInput.val();
                scope.$apply(function () {
                    ngModel.$setViewValue(rawContent);
                });
            }

            var editor = new Markdown.Editor(converter1, "-" + editorUniqueId, {
                handler: help
            });

            editor.run();

            var $wmdInput = $("#wmd-input-" + editorUniqueId);

            $wmdInput.on('keyup', _.debounce(function () {
                rawContent = $wmdInput.val();          // LINE 1
                scope.$apply(function () {             
                    ngModel.$setViewValue(rawContent); // LINE 2
                });
            }, 500));

        }
    }
});

我首先输入字母“q”，然后输入字母“x”，版本为1.2.3：

efore change: ngModel.$modelValue:zzx pagedownAdmin.js:68
Before change: ngModel.$viewlValue:undefined pagedownAdmin.js:69
After change: ngModel.$modelValue:q pagedownAdmin.js:72
After change: ngModel.$viewlValue:undefined pagedownAdmin.js:73
Before change: ngModel.$modelValue:zzx pagedownAdmin.js:68
Before change: ngModel.$viewlValue:undefined pagedownAdmin.js:69
After change: ngModel.$modelValue:x pagedownAdmin.js:72
After change: ngModel.$viewlValue:undefined pagedownAdmin.js:73

似乎每次设置ngModel时，但下一次它进入密钥处理程序时，值都是原始值。

如果您检查它是否适用于大于1.2.2的版本，那就太好了，因此我们知道哪个版本破坏了您的代码，我现在将开始检查每个版本。感谢1.2.3转到第2行，但它似乎没有保存任何内容。W当我与Fiddler检查时，返回服务器的数据与rawContent不匹配。它与原始数据相同。如果我进行更改，它会在{}内正确设置ngModel，但下次我进行另一次更改时，会发现ngModel仍保持原始值。angular.js 1.2.3:

此版本中没有中断更改（承诺！）
