What is the best way to delay a method in vue.js?

In the tab element called competences, there is an input field with the reference search.

<ul class="nav nav-tabs" id="myTab" role="tablist">
    <li class="nav-item">
        <a @click="competencesTabClick" aria-controls="Company" aria-selected="true" class="nav-link active" data-toggle="tab" href="#tab1" id="tab1-tab" ref="tab1" role="tab">Competences
        </a>
    </li>

    <li class="nav-item" v-if="authrzCompetencesEdit">
        <a @click="competencesByUser(0)" aria-controls="other" aria-selected="false" class="nav-link" data-toggle="tab" href="#tab2" id="tab2-tab" role="tab">Logs</a>
    </li>
</ul>

<div class="tab-content" id="myTabContent">

    <div aria-labelledby="tab1-tab" class="tab-pane fade show active" id="tab1" role="tabpanel">

        <div class="row">
            <div class="col-sm-4">
                <div class="form-group">

                    <input @keyup="search($event)" autocomplete="off" class="form-control" ref="search" placeholder="Search" type="text">

                </div>
            </div>
        ....

Upon clicking on the tab, the method @click="competencesTabClick" is executed to focus on the input field with the reference search.

The issue (feel free to correct me) appears to be that the element is not loaded at that time.

Is there a way to delay the execution of the competencesTabClick method until the input element is fully loaded?

Here is the definition of the competencesTabClick function:

competencesTabClick(){
   this.$refs.search.focus();
},

Answer №1

If you find yourself needing to wait until the UI has been refreshed, one option is to utilize the nextTick function. As stated in the Vue documentation, the purpose of nextTick is as follows:

Delay the execution of a callback until after the next DOM update cycle. This can be useful when you need to wait for the DOM to reflect data changes.

To use it in your code, do the following:

competencesTabClick(){
    this.$nextTick(function() {this.$refs.search.focus()});
},

To ensure that this.$refs.search.focus() is executed after a delay, you can wrap it in a setTimeout function like this:

competencesTabClick(){
  setTimeout(() => {
    this.$refs.search.focus()
  }, 200)
}

Alternatively, you can achieve the same result using this.$nextTick:

competencesTabClick(){
  this.$nextTick(function () {
    this.$refs.search.focus()
  })
}
