I am currently attempting to validate whether my variable is empty. Despite reviewing my code, I am facing issues with its functionality.
My current version of vue.js is 2.5.13
Below you can find the snippet of my code:
<template>
<div v-if="Object.keys(this.myValues).length === 0">
This field is empty
</div>
<div v-else>
All good
</div>
</template>
<script>
export default {
data: function() {
return {
myValues: new Object()
};
}
};
</script>
Here is an example showcasing how the data attribute in the current template can be referenced without using this:
var app = new Vue({
el: '#el',
data: function() {
return {
myValues: new Object(),
another: {some:'value'}
}
}
});<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.13/vue.js"></script>
<div id="el">
<div v-if="Object.keys(myValues).length === 0">
myValues is empty
</div>
<div v-else>
myValues have some element
</div>
<div v-if="Object.keys(another).length === 0">
Another is empty
</div>
<div v-else>
Anoter have some element
</div>
