Trying to get the value of an initialization option but it doesn't seem to be returned by init()

I'm trying to write a jasmine test to check that a datatable is being initialized with the correct options.
In my test I create variable to hold the init() options, but for some reason some of the config options are not being returned form the call to init() - specifically the orderMulti option, but it appears to be the case with other options that are set to false in the configuration object.

I have confirmed that when the call to create the contains the config option, so is there any internal code that could be preventing init() returning these options?

Hi @hugh.law ,

I just tried it here, and as you can see, the orderMulti is being displayed. Would you be able to modify that example and see if you can reproduce the problem you're seeing, please?

Cheers,

Hi @colin, thanks for your reply and yes, it was actually being returned correctly, my mistake.

For a bit of context in case someone else finds this answer in the future - I had a series of tests that would each create an instance of a DataTable and the test would check the init() options for each instance. However, In my case, I was not destroy()ing each instance correctly after each test.

DataTables will not create a new instance if a table already has DataTables applied to it - so in my case, while the first test saw the expected init options, in the second test, instead of returning the config options I thought I was setting, init() was returning the options from the first DataTable I had created in the first test.

The solution was to ensure that I called the destroy() method at the end of each test.

it('should prevent sorting on multiple columns if the option is specified as false', function() {
  result = testTable.DataTable({
    orderMulti: false
  });
  dtInitOptions = result.init();
  expect(dtInitOptions.orderMulti).toEqual(false);
  result.destroy(); // this is the all important destroy to stop poisening other tests
});
