無法使用'in'運算符來搜索'model'

Question

來自同一個對象的問題很多。但我的情況有點不同。區別在於，在我的問題中，我沒有使用任何骨幹模型僅骨幹視圖。

我只使用Backbone View。以下是我初始化視圖時的錯誤堆棧。

Uncaught TypeError: Cannot use 'in' operator to search for 'model' in ace-edit-spec-examples-1-8 
(anonymous function) underscore.js:783 
_.each._.forEach underscore.js:78

任何幫助？

編輯：

我看來

var AceEditorView = Backbone.View.extend({ 
     initialize: function (id,type,here) { 
      this.id = id; 
      this.type = type; 
      this.here = here; 
      //this.render(); 
     }}); 

我的電話：

new AceEditorView('ace-edit-spec-examples-1-'+json.id,'json',this);

的簽名Backbone.View.constructor/Backbone.View.initialize是new View([options])，所以你必須通過你的參數選項的哈希值。嘗試

var AceEditorView = Backbone.View.extend({ 
    initialize: function (opts) { 
     this.id = opts.id; 
     this.type = opts.type; 
     this.here = opts.here; 
    } 
}); 

並創建實例作爲

new AceEditorView({ 
    id: 'ace-edit-spec-examples-1-'+json.id, 
    type: 'json', 
    here: this 
});
