202 Resolve when the vue page loads 1-01-22

Solve the problem of { {message}} flash back when vue page is loaded. When
used together with css rules such as [v-cloak]{display:none}, this instruction can hide uncompiled Mustache tags until the instance is ready.
The v-cloak command can bind a set of css styles like a css selector, and then this set of css will be effective until the end of the instance compilation.

eg:
    // <div> 不会显示，直到编译结束。
    [v-cloak]{
        display:none;
            }
    <div v-cloak>
         {
   
   { message }}
    </div>
