XForms/帶原點的插入
< XForms
您希望將新值插入模型例項中，並指定在何處查詢插入的初始值。
您可以向 insert 語句新增 origin 屬性，以告訴 XForms 在何處獲取插入的初始資料。這是優於執行多個 setvalues 的方法。insert 語法的格式如下
<xf:insert ev:event="DOMActivate"
nodeset="instance('persons')/Person"
at="last()" position="after"
origin="instance('init')/Person"/>
一個示例螢幕影像。許多人無法執行示例，因此這一點至關重要。
使用此格式
確保您使用許可證標記所有影像。如果您願意，請使用“署名-相同方式共享 3.0” 創作共用。
確保在 svn 系統中將 mime 型別設定為 text/xml。
