For how to use the vue in ref

Before the project is passed by ref father and son in a number of component data, but the use of other specific ref did not get to the bottom, so take a look at the specific use of ref

first：

    <div REF = " Hello " > 
<-! bound value of the data inside and rendered into the page -> 
      <= h1 of V-Model " MSG " > {{MSG}} </ h1 of> 
    </ div> 
/ / method of acquiring data or function in the life cycle of

console.log(this.$refs.hello.innerText);

second：

components: {node} // Register subassembly

<Node ref = " Node " > 111222 </ Node>
 // used in the form subassemblies and subassemblies used in ref

the console.log ( the this $ refs.node.);
 // The method of obtaining the subassembly and process properties by refs

 

This is to obtain the contents of the entire sub-assembly
