vue-context

A simple yet flexible context menu for Vue. It is styled for the standard ul tag, but any menu template can be used. The only dependency this package has is Vue, so the majority of styling is up to you, and any package styles for the menu can easily be overridden.

The menu disappears when you expect by using the onblur event and it also disappears when clicked on.

Note

The API has changed. Check v2.0.1 documentation if you use the old version.

Getting Started

The following instructions will help you get the vue-context menu up and running on your project.

Installation

Using npm:

$ npm install vue-context --save

Basic Usage

Import the package and use it in your Vue instance, and add a simple method for the click event.

import Vue from 'vue';
import { VueContext } from 'vue-context';

new Vue({
    components: {
        VueContext
    },
    
    methods: {
        /**
         * Alert the text of the menu item that was clicked on.
         * 
         * @param {string} text
         */
        onClick (text) {
            alert(`You clicked ${text}!`);
        }
    }
}).$mount('#app');

Add an element to the page that will trigger the context menu to appear, and also add the context menu to the page.

<div id="app">
    
    <div>
        <p @contextmenu.prevent="$refs.menu.open">
            Right click on me
        </p>
    </div>
    
    <vue-context ref="menu">
        <ul>
            <li @click="onClick($event.target.innerText)">Option 1</li>
            <li @click="onClick($event.target.innerText)">Option 2</li>
        </ul>
    </vue-context>
    
</div>

@contextmenu.prevent is the event listener needed to open the context menu. It is using .prevent as a modifier to prevent the default behavior. It has a ref of menu, which is what $refs.menu is referring to. When each item is clicked on, the text of the item is sent to the onClick method on the Vue instance, which is then shown in an alert.

Advanced Usage

To pass any data from the contextmenu event to your template, you can pass it as the second parameter of open and access it within a scoped slot under the data property. $event must be passed as the first parameter, otherwise the context menu will not function properly.

<div id="app">
    
    <p @contextmenu.prevent="$refs.menu.open($event, { foo: 'bar' })">
        Right click on me
    </p>
    
    <vue-context ref="menu">
        <ul slot-scope="child">
            <li @click="onClick($event.target.innerText, child.data)">Option 1</li>
            <li @click="onClick($event.target.innerText, child.data)">Option 2</li>
        </ul>
    </vue-context>
    
</div>

Now the onClick method on the Vue instance has access to any user data passed to it, which in this case is an object with a property named foo. The data slot scope can also be used to output dynamic content to the context menu.

import Vue from 'vue';
import { VueContext } from 'vue-context';

new Vue({
    components: {
        VueContext
    },
    
    methods: {
        /**
         * Alert the text of the menu item that was clicked on.
         * Console log the data sent from the menu.
         * 
         * @param {string} text
         * @param {object} data
         */
        onClick (text, data) {
            alert(`You clicked ${text}!`);
            console.log(data);
            // => { foo: 'bar' }
        }
    }
}).$mount('#app');
