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

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 — Gurmukh Singh

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.

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

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;
}
