1.hover时候出现,总体来说只改了一下两个index.vue,还有route文件

src\layoutTwo\index.vue

<template>
<div class="main_container_webgl">
<!-- <div :class="classObj" class="app-wrapper">
<div v-if="device==='mobile'&&sidebar.opened" class="drawer-bg" @click="handleClickOutside" /> <div >
<div :class="{'fixed-header':fixedHeader}">
</div> -->
<app-main /> <div class="my_menu_hover">
<sidebar />
</div>
</div>
</template> <script>
import {
Navbar,
Sidebar,
AppMain
} from './components'
import ResizeMixin from './mixin/ResizeHandler' export default {
name: 'LayoutTwo',
components: {
Navbar,
Sidebar,
AppMain
},
mixins: [ResizeMixin],
computed: {
sidebar() {
return this.$store.state.app.sidebar
},
device() {
return this.$store.state.app.device
},
fixedHeader() {
return this.$store.state.settings.fixedHeader
},
classObj() {
return {
hideSidebar: !this.sidebar.opened,
openSidebar: this.sidebar.opened,
withoutAnimation: this.sidebar.withoutAnimation,
mobile: this.device === 'mobile'
}
}
},
methods: {
handleClickOutside() {
this.$store.dispatch('app/closeSideBar', {
withoutAnimation: false
})
}
}
}
</script> <style lang="scss" scoped>
