[英]Uncaught TypeError: binding.destroy is not a function in ExtJs 5
I am using Ext.util.StoreHolder
mixin in my extjs 5.1
view.I found problem with Ext.destroy()
method which throws error while destroying view having bindable mixin Ext.util.StoreHolder . 我在
extjs 5.1
视图中使用Ext.util.StoreHolder
mixin。我发现Ext.destroy()
方法存在问题, Ext.destroy()
方法在破坏具有可绑定的mixin Ext.util.StoreHolder的视图时引发错误。 I can not destroy that view, it giving me error 我无法破坏这种观点,这给了我错误
Uncaught TypeError: binding.destroy is not a function
未被捕获的TypeError:binding.destroy不是函数
at Ext.define.privates.removeBindings
在Ext.define.privates.removeBindings
My view is using mixin: 我的看法是使用mixin:
mixins: {
bindable: 'Ext.util.StoreHolder'
},
Is there any problem with Ext.util.StoreHolder mixin? Ext.util.StoreHolder mixin有问题吗? Why can't I destroy that view?
我为什么不能破坏那个观点?
Edit -> , please find my code 编辑->,请找到我的代码
Ext.define('MyApp.view.ux.CustomPagingBar', {
extend: 'Ext.toolbar.Toolbar',
alias : 'widget.custompagingbar',
mixins: {
bindable: 'Ext.util.StoreHolder'
}
});
Find Fiddle here Grid with Paging bar destroy issue 在此处找到小提琴, 使用分页栏破坏问题
Make sure that you are unbinding the store when destroy is called on the view. 当在视图上调用destroy时,请确保您解除绑定存储。
I think this should work. 我认为这应该有效。
Ext.define('MyApp.view.ux.CustomPagingBar' ,{
extend: 'Ext.toolbar.Toolbar',
alias : 'widget.custompagingbar',
mixins: {
bindable: 'Ext.util.StoreHolder'
},
// other code
onDestroy: function(){
var me = this;
me.bindStore(null);
// some other custom code if you want
me.callParent();
}
});
// me.bindStore(null); this will unbind the store from the view before it is destroyed
In Ext JS 5, Ext.mixin.Bindable has a new config--"bind"--
which allows bind descriptors to be defined on components. 在Ext JS 5中,
Ext.mixin.Bindable has a new config--"bind"--
该配置允许在组件上定义绑定描述符。
In my component's "bind" method is overwriting this, and so the binding cleanup process is trying to destroy a binding, but doesn't have the proper configuration for it. 在我组件的“ bind”方法中覆盖了此方法,因此绑定清理过程试图破坏绑定,但没有适当的配置。
Commenting "bind" method prevent the destroy issue. 注释“绑定”方法可防止破坏问题。
