I'm working on implementing a number input field in Vue 3 that restricts the user from entering a value less than 1. Currently, I have set the minimum value to 1 to prevent using the input arrows to go below 1:
<input min="1" type="number" />
However, users can still manually input 0 or a negative number. How can I further restrict the input to only allow numbers greater than or equal to 1?
Make sure to verify the value with keyup:
const { ref } = Vue
const app = Vue.createApp({
setup() {
const numValue = ref(null)
const setMin = () => {
if(numValue.value < 1) numValue.value = null
}
return { numValue, setMin }
},
})
app.mount('#demo')<script src="https://unpkg.com/vue@3/dist/vue.global.prod.js"></script>
<div id="demo">
<input @keyup="setMin" min="1" v-model="numValue" type="number" />
