I want to display values from my json but I don't know how to do it. Is it possible to loop inside an object array ? i don't know if the keyvalue pipe can help me but I want to do without.
how to get the student2 and also the name to display it ?
thanks everyone.
json
{
"student": {
"student1": [],
"student2": [
{
"id": "123",
"name": "boot"
},
"student3": [],
]
},
"teacher": {
"teacher1": [],
"teacher2": [
{
"id": "123456",
"name": "toto"
},
]
}
}
ts.file
get(){
this.service.getAll().subscribe((data:any) => {
object.keys(data).length > 0;
})
}
Assuming your JSON object from your GET request looks like the one you posted above simply do:
get(){
this.service.getAll().subscribe((data:any) => {
data.student.forEach(element => {
for (let key in element) {
console.log(" key:", key, "value:", element[key]);
for (let val in element[key]) {
console.log(" value:", val);
}
}
});
})
}
