Can anyone help me with checking the existence of "novalue"? For instance:
{
name: "maria",
city_id: "novalue"
....
}
What would be the best way to do this in Vue?
Should I use <div v-if="condition"> or a function?

If you are interested in utilizing ES7 features:
const checkKey = (obj, key ) => Object.keys(obj).includes(key);
Here is an example of how it can be implemented:
const myObject = {name: 'John', age: 30};
const hasName = checkKey(myObject, 'name');
const hasGender = checkKey(myObject, 'gender');
console.log(hasName, hasGender); // true, false
For Vue.js users:
Component:
{
methods: {
checkKey(obj, key ) {
return Object.keys(obj).includes(key);
}
},
computed: {
hasName() {
return this.checkKey(this.someData, 'name');
}
}
}
Template:
<div v-if="hasName"></div>
