Trying to implement an input field in vue.js that only accepts integer values, ensures the quantity is not 0, and defaults to 1 if left empty. I attempted to block decimals with the code:
<input type="number" min="1" @keydown="filterKey"></input>
filterKey(e){
const key = e.key;
if (key === '.')
return e.preventDefault();
}
However, I am unsure how to implement the other filters. Any suggestions on how to achieve this?
give this a shot: script:
data: () => ({
count: 1
}),
methods: {
checkKey(event) {
const keyPress = event.key;
if (keyPress === ".") return event.preventDefault();
},
updateNum(event) {
if (!this.count || parseInt(this.count, 0) === 0) this.count = 1;
else this.count = parseInt(this.count, 0);
}
}
template:
<input type="number" v-model="count" @keydown="checkKey" @blur="updateNum">
