Ember.js ArrayController错误

本文介绍了Ember.js ArrayController错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 我正在尝试测试以下示例Ember.js代码，但我总是在Chrome浏览器控制台中显示以下错误： 未捕获TypeError：对象[object Object]的属性'_super'不是函数 代码： MovieTracker.movi​​esController = Ember.ArrayController.create（{ content：[]， init：function（）{ this._super（）; var list = [ MovieTracker.Movie.create（{ title：'Movie 1'，评分：4}）， MovieTracker.Movie.create（{标题：电影2，评分：5 }）]; this.set （'content'，list）; } }）; 我正在使用Ember-1.3.2.js $ b $有人可以告诉我我在这里缺少什么？以及如何解决这个错误？ 根据@ kingpin2k的建议，将.create转换为.extend后的新错误消息 TypeError：Object function（）{if（！wasApplied）{Class.proto（）; // 准备原型...} o_defineProperty（这是GUID_KEY， undefinedDescriptor）; o_defineProperty（this，'_super'， undefinedDescriptor）; var m = meta（this），proto = m.proto; m.proto = this; if（initMixins）{//在本地捕获，所以我们可以通过变量var mixins = initMixins清除已关闭的; initMixins = null; this.reopen.apply（this，mixins）; } if（initProperties）{//在本地捕获，以便我们可以清除已关闭的变量var props = initProperties; initProperties = null; var concatenatedProperties = this.concatenatedProperties; for（var i = 0，l = props.length; i< l; i ++）{var properties = props [i]; Ember.assert（Ember.Object.create no longer support in other definition，use createWithMixins instead。，！（properties instanceof Ember.Mixin））; if（typeof properties！=='object'&& properties！== undefined）{throw new Ember.Error（Ember.Object.create只接受对象）;如果（！properties）{continue; } var keyNames = Ember.keys（properties）;对于（var j = 0，ll = keyNames.length; j< ll; j ++）{var keyName = keyNames [j]; if（！properties.hasOwnProperty（keyName））{continue; } var value = properties [keyName]，IS_BINDING = Ember.IS_BINDING;如果（IS_BINDING.test（keyName））{var bindings = m.bindings; if（！bindings） {bindings = m.bindings = {}; } else if （！m.hasOwnProperty（'bindings'））{bindings = m.bindings = o_create（m.bindings）; } bindings [keyName] = value; } var desc = m.descs [keyName]; Ember.assert（Ember.Object.create不再支持定义计算属性，！（value instanceof Ember.ComputedProperty））; Ember.assert（Ember.Object.create不再支持定义调用_super的方法，！（typeof value === 'function'&& value.toString（）。indexOf （'._super'）！== -1））; Ember.assert（ actions 必须在延长时间提供，而不是在使用Ember.ActionHandler时创建+意见+ 控制器和路由），！（（keyName ==='actions'）&&b $ b Ember.ActionHandler.detect（this）））; if（concatenatedProperties& indexOf（concatenatedProperties，keyName）> = 0）{var baseValue = this [keyName]; if（baseValue）{if（'function'=== typeof baseValue.concat）{value = baseValue.concat（value）; } else {value = Ember.makeArray（baseValue）.concat（value）; }} else {value = Ember.makeArray（value）; }} if（desc）{desc.set（this，keyName， value）; } else {if（typeof this.setUnknownProperty ==='function'&& ！（keyName in this））{this.setUnknownProperty（keyName，value）; } else if（MANDATORY_SETTER）{Ember.defineProperty（this，keyName，null， value）; // setup mandatory setter} else {this [keyName] = value; }} }}} finishPartial（this，m）; this.init.apply（this，arguments）; m.proto = proto; finishChains（本）; sendEvent（this，init）; }没有方法'get' 解决方案经过大量的试验，问题出现在控制器名称的拼写和案例中。例如（根据您的问题代码）调用： MovieTracker.movi​​esController.get（'length'）; 而控制器的名称为MoviesController，大写M将会给您此错误。所以请尝试双重检查您的代码，确保您的正确名称正确。 保持控制器名称与资本M也是一个很好的做法@ kingpin2k推荐 I am trying to test the following sample Ember.js code but I am always getting the following error displayed in the Chrome browser console:Uncaught TypeError: Property '_super' of object [object Object] is not a functionCode:MovieTracker.moviesController = Ember.ArrayController.create({ content: [], init: function(){ this._super(); var list = [ MovieTracker.Movie.create({ title: 'Movie 1', rating: 4 }), MovieTracker.Movie.create({ title: 'Movie 2', rating: 5 })]; this.set('content', list); }});I am using Ember-1.3.2.jscan someone please tell me what I am missing here? and how to solve this error?New error message after changing .create to .extend as recommended by @kingpin2k TypeError: Object function () { if (!wasApplied) { Class.proto(); // prepare prototype... } o_defineProperty(this, GUID_KEY, undefinedDescriptor); o_defineProperty(this, '_super', undefinedDescriptor); var m = meta(this), proto = m.proto; m.proto = this; if (initMixins) { // capture locally so we can clear the closed over variable var mixins = initMixins; initMixins = null; this.reopen.apply(this, mixins); } if (initProperties) { // capture locally so we can clear the closed over variable var props = initProperties; initProperties = null; var concatenatedProperties = this.concatenatedProperties; for (var i = 0, l = props.length; i < l; i++) { var properties = props[i]; Ember.assert("Ember.Object.create no longer supports mixing in other definitions, use createWithMixins instead.", !(properties instanceof Ember.Mixin)); if (typeof properties !== 'object' && properties !== undefined) { throw new Ember.Error("Ember.Object.create only accepts objects."); } if (!properties) { continue; } var keyNames = Ember.keys(properties); for (var j = 0, ll = keyNames.length; j < ll; j++) { var keyName = keyNames[j]; if (!properties.hasOwnProperty(keyName)) { continue; } var value = properties[keyName], IS_BINDING = Ember.IS_BINDING; if (IS_BINDING.test(keyName)) { var bindings = m.bindings; if (!bindings) { bindings = m.bindings = {}; } else if (!m.hasOwnProperty('bindings')) { bindings = m.bindings = o_create(m.bindings); } bindings[keyName] = value; } var desc = m.descs[keyName]; Ember.assert("Ember.Object.create no longer supports defining computed properties.", !(value instanceof Ember.ComputedProperty)); Ember.assert("Ember.Object.create no longer supports defining methods that call _super.", !(typeof value === 'function' && value.toString().indexOf('._super') !== -1)); Ember.assert("actions must be provided at extend time, not at create " + "time, when Ember.ActionHandler is used (i.e. views, " + "controllers & routes).", !((keyName === 'actions') && Ember.ActionHandler.detect(this))); if (concatenatedProperties && indexOf(concatenatedProperties, keyName) >= 0) { var baseValue = this[keyName]; if (baseValue) { if ('function' === typeof baseValue.concat) { value = baseValue.concat(value); } else { value = Ember.makeArray(baseValue).concat(value); } } else { value = Ember.makeArray(value); } } if (desc) { desc.set(this, keyName, value); } else { if (typeof this.setUnknownProperty === 'function' && !(keyName in this)) { this.setUnknownProperty(keyName, value); } else if (MANDATORY_SETTER) { Ember.defineProperty(this, keyName, null, value); // setup mandatory setter } else { this[keyName] = value; } } } } } finishPartial(this, m); this.init.apply(this, arguments); m.proto = proto; finishChains(this); sendEvent(this, "init"); } has no method 'get' 解决方案 I had the same problem before and after a lot of trials the problem was in the controller name spelling and case. For example (based on your question code) calling: MovieTracker.moviesController.get('length');while the name of the controller is MoviesController with a capital M will give you this error. So try double checking your code, make sure you have the correct name with correct case.It is also a good practice to keep controller name with capital M as @kingpin2k recommended 这篇关于Ember.js ArrayController错误的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
