Note:

You need to find the components of the overall layout of the page in the project, such as the project uses Home.vue as the public layout of the entire project, and set the positioning of the root element to relative so that the right-click menu is positioned relative to it.

The right-click menu in this paper is mainly implemented by vuex.

1. Define the global state in vuex to manage the right-click menu

Export default {/ * menuContent format: * [* {* name: 'create a file', / / operation name * method: 'createDirectory', / / the method in the corresponding component to be executed * disabled: true / / is disabled or not Can be adjusted according to the specific logic of the page *} *] * the overall right-click menu adopts absolute positioning So the representatives of clientX and clientY are left and top location * / state: {menuContent: [], / / right-click menu content clientX:', / / left clientY:', / / top displayContextMenu: false / / whether to display right-click menu}, mutations: {SET_CONTEXT_MENU: (state) Payload) = > {state.menuContent = payload.menuContent State.clientX = payload.clientX; state.clientY = payload.clientY; state.displayContextMenu = payload.displayContextMenu;},}}

Second, define the common component ContextMenu.vue

{{item.name}} import {mapState} from 'vuex';import bus from' @ / views/common/bus' Export default {name: 'ContextMenu', data () {return {}}, computed: {... mapState ([' contextMenu'])}, methods: {emitEvent (type) {bus.$emit ('operateDirectory', type)} .context-menu {position: absolute; background: # FFF Color: # 34495E; min-width: 100px; box-shadow: 0px 2px 4px 0px rgba (0,0,0,0.2); border-radius: 2px; cursor: pointer; z-index: 1002; & > ul {text-align: left; padding: 5px 10px; & > li {padding: 3px 4px Font-size: 12px; list-style: none; height: 24px; line-height: 24px; &: hover {background: # EDF6FF;}} .hover {color: # 888585 Pointer-events: none;}

Third, use in components

Import {mapState} from 'vuex';//... computed: {. MapState ([' contextMenu'])}, created () {bus.$on ('operateDirectory', (param) = > {/ / right-click menu) should trigger a method with the same name in the component. First, we should determine whether the method exists in this component, and call if (thisparam) {this [param] () }});}, / /... methods: {showContextMenu (event, data) {event.preventDefault () / / default event const menuContent for blocking browsers = {menuContent: [{icon: "el-icon-upload2", name: "run", method: "run",}, {icon: "el-icon-refresh" Name: "edit", method: "editConfig",}, {icon: "el-icon-refresh", name: "add", method: "addCommond",}, {icon: "el-icon-refresh" Name: "delete", method: "deleteConfig",},], clientX: event.clientX, clientY: event.clientY, displayContextMenu: true,} This.$store.commit ("SET_CONTEXT_MENU", menuContent); / / Click the page again, and the right-click menu disappears _ document.onclick = (event) = > {this.$store.commit ("SET_CONTEXT_MENU", {displayContextMenu: false,});} }, run () {/ /...}, editConfig () {/ /...}, addCommond () {/ /...}, deleteConfig () {/ /...}} "how to customize the global right-click menu for vue" ends here, thank you for reading.
