Is it correct that whenever the getVal function is called, a new dictionary should be created and its values replaced?
var dict = [];
function getVal(inarr, element, data) {
var arr = inarr[element].map((item) => item[data]);
return arr;
};
console.log(getVal(event, 'foo', 'bar'));
const retrieveData = (inputArray, element, info) => {
let extractedData = inputArray[element].map((item) => item[info]);
return extractedData;
};
console.log(retrieveData(event, 'foo', 'bar'));
Due to the lack of clarity in your query and missing input, any response will be a bit speculative. However, you might want to consider implementing something along these lines:
// The 'keys' variable can be an array containing strings or functions.
// If it's a function, it will receive the current object as an argument.
function getMember(object, keys) {
return keys.reduce(function(acc, key) {
if (acc === undefined) {
return acc;
}
if (typeof key === "function") {
return key(acc);
}
return acc[key];
}, object);
}
function getVal(object) {
return getMember(object, [
"foo",
function(x) {
return x.map(function(x){
return x.bar;
});
}
]);
};
var event = {
foo: [
{ bar: 1 },
{ bar: 2 }
]
};
console.log(getVal(event)); // Output: [1, 2]Each time the Create Sales Order Button is clicked, an API call is made and the response is printed as a Stateful Component. Rather than updating the existing component, I want to generate a new paragraph for each response received so that if the user clic ...
