javascript - 道场: Cannot read property 'h' of undefined on AccordionContainer. js？

Question

当我在 Accordion 容器下动态创建两个 Accordion 容器时，出现这样的错误。

当我创建这些单个 Accordion 容器中的任何一个而不是一起创建时，不会发生错误。

Error :

Cannot read property 'h' of undefined on AccordionContainer.js

我已经通过将这些行添加到工具包文件来临时解决了这个问题，dojo-toolkit\dijit\layout\AccordionContainer.js

Line 91: + if(this._contentBox) 
Line 92:    this._verticalSpace=_34.h-_35-_2f.h-_30.h-_32.h-_33.h-_2d._buttonWidget.getTitleHeight(); 
Line 93: + if(this._contentBox) 
Line 94:    this._containerContentBox={h:this._verticalSpace,w:this._contentBox.w-_2f.w-_30.w-_32.w- _33.w}; 

Accordion Widget 创建代码结构为

define("test/project", [ 
        "dojo/_base/declare", 
        "dijit/_Widget", 
        "dijit/layout/AccordionContainer"], 
    function(declare, _Widget, AccordionContainer) { 
        return declare([_Widget],{ 
                         postCreate: function() { 
                                var new_acc = new AccordionContainer({ 
                                        id: "new_acc", 
                                        title: "Approval ("+this.count+")" 
                                }); 

                               this.parentId.addChild(new_acc); 
                        } 
        });     
}); 

有解决这个问题的想法吗？

提前致谢...

我遇到了同样的问题，但我想通了。当您尝试在 aContainer.startup() 之后用 Accordion 创建另一个 child 时；方法，它将生成相同的错误消息。启动方法启动 Accordion ，它将动态地将高度和宽度应用于该 Accordion ，如果您在创建 Accordion 后再次为其创建子级，它将抛出错误“无法读取 AccordionContainer.js 上未定义的属性‘h’”

      aContainer = new AccordionContainer({ style: "height: 300px" },acdic);
        aContainer.addChild(new ContentPane({
            title: "This is a content pane",
            content: "Hi!"
        }));

        aContainer.addChild(new ContentPane({
            title: "This is as well",
            content: "Hi how are you?",
            id: "pane1"
        }));
        aContainer.startup();            
        aContainer.addChild(new ContentPane({
            title: "This too",
            content: "Hello im fine.. thnx"
        }));
