delete object element within an array

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

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;
}

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
