Use v-if to optimize page loading

In the Vue page, some modules may need to be triggered actively to display, such as pop-up components and other sub-components, then we can use v-if to render on demand, there is no need to render all modules as soon as you enter the page. For example:

Import moduleB from 'components/moduleB'export default {data () {return {isShowModuleB: false}}, components: {moduleB}}

In this way, when isShowModuleB is false, the code under the module will not be loaded, including some time-consuming interface calls. Of course, v-if is mainly suitable for the display and hiding of modules with a large amount of code and users do not click very frequently, and if the code involving permission issues needs to use v-if, not v-show.
