Currently facing an issue where I need to restrict input to no more than 2 decimal places. I came across a solution in a thread on Stack Overflow which addresses this using jQuery: JQuery allow only two numbers after decimal point. However, I am looking for the Vue.js equivalent.
Consider using a watch function to monitor the input value and reformat it as needed:
Vue.config.devtools = false;
Vue.config.productionTip = false;
new Vue({
el: '#app',
data() {
return {
num: 0
}
},
watch: {
num(newVal, oldVal) {
if (newVal.includes('.')) {
this.num = newVal.split('.')[0] + '.' + newVal.split('.')[1].slice(0, 2)
}
}
}
})<link type="text/css" rel="stylesheet" href="//unpkg.com/bootstrap/dist/css/bootstrap.min.css" />
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.16/vue.js"></script>
<div id="app" class="container">
<input type="number" class="number" v-model="num" />
