Is there a way to execute a function only once while still having it run each time a new element is created using v-for?
<div v-for"value in values">
<div @ function(value, domElement) if value.bool===true @>
</div>

If you ask me, the most straightforward approach would be to convert each of those elements into a Vue Component and pass the function down as a prop.
Document One
<div v-for="value in values">
<Custom-Component :propValue="value" :propFunction="functionYouNeed" />
</div>
Customized Component
<template>
<div> {{propValue.value}} </div>
</template>
<script>
export default {
props: ['propFunction', 'propValue'],
created(){
if (this.propValue.bool === true) {
this.propFunction()
}
}
}
</script>
It's a bit unclear what you're looking for:
<div @ function(value, domElement) if value.bool===true @>
Here are some possible solutions to consider.
If you want to bind the method with the once modifier:
<div @click.once="yourMethod">
Alternatively, if you prefer not to change the content, you can use v-once:
<div v-once>{{ neverChanged }}</div>
However, if you simply need to use the function when it is created, then call the function within the created property without binding it elsewhere.
created() {
if(condition) {
this.yourMethod()
}
}
