Here is the JSON response I received:
{
"A":{"Option1":true,"Option2":true,"Option3":false}
"B":{"OptionX":true,"OptionY":true,"OptionZ":false}
}
I am attempting to extract the following values into a string: Option1, Option2, OptionX, OptionY
Despite my attempts, I have not been successful. Here is what I have tried:
Array.from(this.model).forEach(child => {
console.log(child, 'child name')
});
Implement flatMap() alongside filter(), where you iterate through each key by utilizing the map function in conjunction with Object.keys()
const data = {
"A": {"Option1":true,"Option2":true,"Option3":false},
"B": {"OptionX":true,"OptionY":true,"OptionZ":false}
};
const res = Object.values(data).flatMap(o => Object.keys(o).filter(k => o[k]));
console.log(res)Iterating through the JSON object to retrieve keys with non-null values using two different methods in JavaScript:
Method 1:
for (const record of Object.values(json)) {
for (const [key, value] of Object.entries(record)) {
if (value) {
console.log(key);
}
}
}
Method 2:
const keys = Object
.values(json)
.map(record => Object
.entries(record)
.filter(([key, value]) => value)
.map(([key]) => key)
)
def filter_options(obj):
result = []
for key, value in obj.items():
if value:
result.append(key)
return result
obj = {
"A": {
"Option1": True,
"Option2": True,
"Option3": False
},
"B": {
"OptionX": True,
"OptionY": True,
"OptionZ": False
}
}
result = filter_options(obj)
