访问模板中的 dijit widget 时 isValid 不是函数错误

我有一个 dijit validtextbox 小部件：

<input dojoAttachPoint="tbIPAddress" type="text" size="15" class="ipaddress"
                    dojoType="dijit.form.ValidationTextBox"
                    required="true"
                    regExp="^(\d{1,3})\.(\d{1,3})\.(\d{1,3})\.(\d{1,3})$"
                    promptMessage="Enter IP Address."
                    invalidMessage="A valid IP Address is required." />

如果我给它一个 id，然后使用 dijit.byId 访问它，那么我可以对其调用 isValid 。但是，如果它位于 dijit 模板化小部件中并使用 dojoAttachPoint，那么当我使用 this.tbIPAddress 在关联的 js 类中访问它时，调用 isValid 会出现以下错误：

this.tbIPAddress.isValid 不是一个函数

我会假设这样做这。会足够聪明，知道是否在幕后执行 dijit.byId 或 dojo.byId ，并提供所有相关功能。我缺少什么？

原文

I have a dijit validationtextbox widget:

<input dojoAttachPoint="tbIPAddress" type="text" size="15" class="ipaddress"
                    dojoType="dijit.form.ValidationTextBox"
                    required="true"
                    regExp="^(\d{1,3})\.(\d{1,3})\.(\d{1,3})\.(\d{1,3})$"
                    promptMessage="Enter IP Address."
                    invalidMessage="A valid IP Address is required." />

If I give it an id and then access it with dijit.byId then I can call isValid on it. However, if it's in a dijit templated widget and is using dojoAttachPoint, then when I access it in the associated js class using this.tbIPAddress, calling isValid gives the following error:

this.tbIPAddress.isValid is not a function

I would assume that doing this. would be smart enough to know whether to do a dijit.byId or dojo.byId behind the scenes and would make available all the pertinent functions. What am I missing?
