Model view controller 使用dojox mvc的dojox mobile日期选择器和交换机不工作
我使用dojox.mvc.at将dojox.mobile.Switch的value属性绑定到模型中的属性。当我在模型中更改属性时，开关会响应这些更改；但是，当我更改switch的状态时，模型中的属性没有得到更新 dojox.mobile.DatePicker也存在同样的问题 我正在使用Dojo1.9.0 有人能帮助解决这个问题吗Model view controller 使用dojox mvc的dojox mobile日期选择器和交换机不工作,model-view-controller,dojo,dojox.mobile,Model View Controller,Dojo,Dojox.mobile,我使用dojox.mvc.at将dojox.mobile.Switch的value属性绑定到模型中的属性。当我在模型中更改属性时，开关会响应这些更改；但是，当我更改switch的状态时，模型中的属性没有得到更新 dojox.mobile.DatePicker也存在同样的问题 我正在使用Dojo1.9.0 有人能帮助解决这个问题吗 <div class="row"> <label for="switch"></label> <div id=

这些小部件有不同的问题。类的组合方式与扩展方式（大多数窗口小部件的基类）不匹配。您需要将扩展显式应用于解决该问题，如：

最好，-Akira我尝试了您提到的对dojox.mobile.Switch的更改，但不起作用。它仍然是单向绑定的（从模型到视图），而不是从视图到模型。我查看了Switch.js文件，发现“value”属性的更新方式与mvc触发的方式不同。我在dojox/mobile/Switch.js中手动添加了三行代码，两行在_onClick函数中，一行在_changeState中，交换机在mvc和out mvc中都可以正常工作。这些更改有效吗
_changeState: function(/*String*/state, /*Boolean*/anim){
我检查了两次，正常行为没有问题，mvc也可以正常工作。如果这些更改有效，请在下一版本中进行这些更改以支持mvc。我明白了，看起来这是有意义的，尽管我不是dojox/mobile的所有者。您可能需要输入bugs.dojotoolkit.org的票证。
