Can clearTimeout be used for a setTimeout function assigned to a Vue Method? If yes, how can it be accomplished?
methods: {
timeoutController() {
setTimeout(function() {
this.controllerShown = false;
}, 3000);
}
....
new Vue({
el: '#app',
data: {
timer: null
},
methods: {
startTimer () {
this.timer = setTimeout(() => {
console.log("execute me")
}, 3000)
},
// Stopping the timer before the setTimeout callback will prevent the callback from being executed
stopTimer () {
if (this.timer) {
clearTimeout(this.timer)
}
}
}
})<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
<button @click="startTimer()">start</button>
<button @click="stopTimer()">stop</button>
</div>What is the purpose of assigning a function to a Vue component's data?
By using the setTimeout() function, we can delay the execution of a specific task by 3000 ms and store the timer in this.timeout. Once the timer is set, it will not run again, regardless of any subsequent assignments.
