nl_tokens: React . createElement 是不能渲染一个 ViewModel 实例的，于是便提供了渲染方法来渲染 vm。
pl_tokens: function mixedRenderer ( <mask> , propsOrClassName , props , ... children ) { if ( model && typeof model === 'object' ) { if ( typeof propsOrClassName === 'string' ) { propsOrClassName = { className : propsOrClassName } props = props || { } props = { ... props , ... propsOrClassName } } else { children = [ props ] . concat ( children ) props = propsOrClassName } return r . apply ( this , [ model , props , ... children ] ) } return h . apply ( this , arguments ) }
