vue force a refresh sub-assemblies

Question: Because the tab parent component of the switch, leading to sub-assemblies there has been no refresh when the parent component by value update, sub-assemblies can not get to.

Resolve: as long as sub-components force a refresh to get the value of props can be passed over the use of characteristic v-if, force a refresh sub-components in the parent assembly. 

　

< Son V-IF = "sonRefresh" > </ Son > 

Data () { 
　　return { 
　　　　sonRefresh: to true 
　　} 
} 

// write the following piece of content within parent components acquired local value 
this.sonRefresh = to false; 
the this $ nextTick (. () => { 
    this.sonRefresh = to true; 
});

The above content is written in the parent assembly.
