delete object element within an array

Question

I have an object, and within the object, i need to delete the address from the array of objects using javascript.

 obj = {
 "name":1,
 "Details":[
 {
 "mname":"text here",
 "sname":"text here",
 "address":"text",
 "saddress":"text"
 }
 ]
 }

I have tried the following, but no luck:

delete obj.Details.address

and

delete obj.Details[0].address

• haim770: The latter should work with no problem
• Gurmukh Singh: There must have been something wrong with the way i might have structured the project, but the latter is now working, thanks for your help everyone

Answer 1

your object structure is wrong

 obj = {
 "name":1,
 "Details":[
 {
 "mname":"text here",
 "sname":"text here",
 "address":"text",
 "saddress":"text"
 }
 ]
 }

it should be "address":"text", in string format then

delete obj.Details[0].address

will work.

• ibrahim mahrir: I don't think that's the problem!
• Gurmukh Singh: my mistake,thats was a typo, the quotes are there

Answer 2

Are you sure this don't work?

delete obj.Details[0].address

I've just tried in the chrome console and this works. Maybe you're not debugging correctly

Answer 3

If you want to delete the adress property of all the objects inside the Details array, then do it using forEach like this:

obj.Details.forEach(function(detail) {
 delete detail.address;
});

Or using an old for loop like this:

for(var i = 0; i < obj.Details.length; i++) {
 delete obj.Details[i].adress;
}
