实例如下,现在想在txt2控件后插入一个div,请问可以实现吗? 目前ZK提供的方法有appendChild、beforeChildAdded、insertBefore,无法实现。

<div>
<textbox id="txt1"/>
<textbox id="txt2"/>
<textbox id="txt3"/>
</div>

EDIT: (google translation) The example is as follows, now I want to insert a div after the txt2 control, can I achieve it?

As shown in this example you can add a component after another one, by inserting it before its next sibling. You have to call the method from the parent component:

txt2.getParent().insertBefore(new Label("inserted"), txt2.getNextSibling())

EDIT:

If the nextsibling doesn't exist it will return null. Calling parent.insertBefore(comp, null) is equivalent to calling parent.appendChild(comp), both will append to the end. In your example after txt3

Please also refer to the related java docs:
