The debounce functionality provided by Lodash does not seem to be functioning properly within VueJS events

I am attempting to incorporate the debounce function into my filter. The goal is to avoid sending a request with each change in input text, and instead, wait for about one second.

However, I'm encountering an issue where the filter doesn't seem to be triggered at all when using _.debounce.

  <div class="md-form">
        <i class="fas fa-search prefix"></i>
        <input type="text" class="form-control" v-model="filter.fulltext" @input="runFilter" id="x">
        <label for="x">Fulltext search</label>
  </div>

var app = new Vue({
        delimiters: ['[[', ']]'],
        el: '#app',
        data: { ....
        methods:{
            runFilter() {
                var self = this;

                _.debounce(function () {
                    self.records_page = 1;
                    self.loadRecords();
                    self.loadMarkers();
                 }, 1000)

               },
               ....

Any idea why the function is not being triggered after one second?

Answer №1

The _.debounce() method creates a function with closure, requiring you to choose a location to store the debounced function. Typically, the debounced function is assigned to a property on 'this' within the created hook.

created() {
   this.debouncedGetAnswer = _.debounce(this.getAnswer, 500)
}

Refer to the official documentation for a similar implementation: https://v2.vuejs.org/v2/guide/computed.html
