Emit event with parameters in vue

The following argument(s) in $emit() are the arguments in your emitted function.

$emit('select-menu-item', $event, 1, 2, 3, 4, "cupcakes")

and in your component method.

selectMenuItem: function(evt, num1, num2, num3, num4, food){

}

And in your actual component markup, you don't need to add arguments, just write the reference to the method without parenthesis.

<search-component v-bind="searchProps" @select-menu-item="selectMenuItem">

SAMPLE

window.onload = function(){
 const component = function() {
    return {
       template: `
       <div>
         <button @click="$emit('click-me', 'foobar')">
            Click Me
         </button>
       </div>
       `,
       props: ["data"]
    }
 }

 new Vue({
       el: container,
       data: {},
       components: { "my-component": component(), },
       methods: {
          clickMe: function(str){
            console.log(str);
          }
       }
    });
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>

<div id="container">
  <my-component :data=$data @click-me="clickMe"></my-component>
</div>

just adding more answer from @Albana Clara.

You can merge your parameter along with the event passed.

EXAMPLE:

<search-component v-bind="searchProps" @select-menu-item="selectMenuItem('test', ...arguments)">

selectMenuItem: function(a, b) {
  console.log(a + " " + b);
  // test foobar
}
