Adding to a javascript object

Question

I have an object in javascript for settings for dataTables.

var dataTableSettings = {
  "iDisplayLength": 25,
  "bLengthChange": false,
  "bSortClasses": false,
};

I then have an if statement to add another option to the object:

if (last_location) {
  dataTableSettings.push(
    "oSearch": {"sSearch": last_location}
  );
}

I know that doesn't work because push() doesn't work on objects, how do I add to the object options list?

Answer 1

dataTableSettings.oSearch = { "sSearch": lastLocation };

Or

dataTableSettings['oSearch'] = { "sSearch": lastLocation };

Answer 2

You have to do it this way:

if (last_location) {
  dataTableSettings.oSearch = {"sSearch": last_location};
}

OR

if (last_location) {
      dataTableSettings["oSearch"] = {"sSearch": last_location};
}

Answer 3

just do this :

dataTableSettings.oSearch = {"sSearch": last_location}

or this (both are equivalent ):

dataTableSettings['oSearch'] = {"sSearch": last_location}
