分明已经定义了变量name,但依然提示:

[Vue warn]: Property or method "name" is not defined on the instance but referenced during render. Make sure that this property is reactive, either in the data option, or for class-based components, by initializing the property.

原因:data中定义的其他变量,有的出错,导致其他的成员没被识别

  data: function() {
    return {
      name:'', 
 
      table1: new listtable( 
        this.parent.id,  //此处出错, 原因this.parent此时为null
      ),
 }

或者因为一些前面的 v-model="xxx" 

但是xxx没有在data中定义
