let schoolData = { "name": "naam",
"schools" : [
"silver stone" ,
"woodlands stone" ,
"patthar"
],
"class" : 12 }
schoolJSON = JSON.stringify(schoolData) ;
let jsonData = JSON.parse(schoolJSON) ;
jsonData.forEach(element => {
console.log(element.schools) ;
});
I am attempting to display the names of schools, but encountering an error:
" Uncaught TypeError: json.forEach is not a function "
Seeking assistance in resolving this issue.
When using the forEach method, it is important to note that it only works on array-type data.
let myJSON = {
"name": "naam" ,
"schools" : [
"silver stone" ,
"woodlands stone" ,
"patthar"
],
"class" : 12}
let info = document.getElementById("info");
let clickme = document.getElementById("clickme");
myJSON = JSON.stringify(myJSON) ;
/* "json" variable has an object type data */
let json = JSON.parse(myJSON) ;
// The For Each function can only be used on arrays.
// It cannot be directly applied to loop through an object
json.schools.forEach(e => {
console.log(e) ;
});
Therefore, if you want to iterate through the school array within json.schools, you should use forEach on "json.schools", which is an Array, rather than on the "json" variable containing object data.
