Question

Could someone help me to create a JavaScript function that would turn the string below into an Object?

var structure = 'user.location.city';

When ran through the JavaScript function would return an object structured like this:

user: {
  location: {
    city: {}
  }
}

I came up with the code below, but the object is messed up:

var path = structure.split('.');
var tmp_obj = {};
for ( var x = 1; x < path.length; x++ ) {
   tmp_obj[path[x]] = {};
};

I don’t know how to add the “city” Object to the “location” Object.

Answer 1

var path = structure.split('.');
var tmp_obj = {};
var obj = tmp_obj;
for(var x = 1; x < path.length; x++) {
    tmp_obj[path[x]] = {};
    tmp_obj = tmp_obj[path[x]];
};
