VisualizaçõesRound up a number in the v-model in vuejs
i want to round up this number in my input:
<b-form-input id="amount_input" type="number"
v-model="Math.ceil(form.contract.reward_cents / 100)"
:state="validate(form.contract.reward_cents)"/>
I tried to do Math.ceil() but i'm getting this error
Can anyone help me fix it?
I solved it like this:
computed: {
reward_cents () {
return Math.ceil(this.form.contract.reward_cents / 100);
},
}
<template>
<b-form-input id="amount_input" type="number" v-model="reward_cents"
:state="validate(form.contract.reward_cents)"/>
</template>

Maybe you can try to use a computed property in v-model instead of an expression.
<b-form-input id="amount_input" type="number"
v-model="reward_cents"
:state="reward_cents"/>
<script>
export default {
computed: {
reward_cents: {
get() {
return this.form.contract.reward_cents;
},
set(val) {
this.form.contract.reward_cents = Math.ceil(val / 100);
}
}
}
}
</script>

you can follow:
<b-form-input
id="amount_input"
type="number"
:value="form.contract.reward_cents"
v-model="reward_cents"
@change="OnChange"
:state="validate(form.contract.reward_cents)"/>
data(){
return: {
reward_cents: 0
}
}
methods: {
OnChange(newVal){
this.reward_cents = Math.ceil(newVal / 100);
}
}
