Utilizing Vue's dynamic component feature to create event listeners

Issue: My current project involves creating a versatile table component that can be utilized by other components to display tabular data. Each cell in this table could contain one of three possible values:

  • Text
  • HTML
  • Component

While I have successfully implemented the rendering of these values, I am facing difficulty in binding an event listener. What I aim to achieve is the ability to pass a method and event to the component, which should then bind them to the respective cell.

For instance:

TABLE JSON

{
   "cell-1":{
      "type":"html",
      "data":"<h4>text-1</h4>",
      "method": someMethod
   }
}

TABLE COMPONENT

<tbody>
   <template>
      <tr>
         <td  >
            <span
               v-if="type == 'html'"
               v-html="data"
               v-on:click.native="$emit(someMethod)"
               v-on:click.native="someMethod"
            ></span>
         </td>
      </tr>
   </template>
</tbody>

The above code snippet showcases my current approach where the table dynamically renders cells based on the object passed as input.

I have already explored solutions provided on Stack Overflow such as:

If you require additional information or have suggestions, please feel free to share them with me.

Answer №1

To efficiently handle methods within components, it is recommended to place the method/handler in the parent component and then utilize the emit functionality to trigger it.

IMPLEMENTATION IN TABLE COMPONENT

  <tbody>
   <template>
      <tr>
         <td  >
            <span
               v-if="type == 'html'"
               v-html="data"
               v-on:click.native="$emit('trigger-handler', {method: 'method1', data: {}})"
               ></span>
         </td>
      </tr>
   </template>
</tbody>

and in

PARENT COMPONENT (Parent.vue)

<table-component @trigger-handler="triggerHandler" />

within script section of Parent.vue file:

export default {
 data() {
 },
 methods: {
  triggerHandler(payload) {
   // payload represents the object transmitted from the child component
   this[payload.method](payload.data); // invoking a specific method based on payload
  },
  method1(data) {
  },
  method2(data) {
  },
  method3(data) {
  }
 }
}
