XForms/带原点的插入
< XForms
您希望将新值插入模型实例中，并指定在何处查找插入的初始值。
您可以向 insert 语句添加 origin 属性，以告诉 XForms 在何处获取插入的初始数据。这是优于执行多个 setvalues 的方法。insert 语法的格式如下
<xf:insert ev:event="DOMActivate"
nodeset="instance('persons')/Person"
at="last()" position="after"
origin="instance('init')/Person"/>
一个示例屏幕图像。许多人无法运行示例，因此这一点至关重要。
使用此格式
确保您使用许可证标记所有图像。如果您愿意，请使用“署名-相同方式共享 3.0” 创作共用。
确保在 svn 系统中将 mime 类型设置为 text/xml。
