How would I set up a jasmine spy to return a value from an input box based on the passed in selector in jQuery?

Question

I'm trying to create a spy on Jquery that's making a call like:

$('#AccountNumber').val();

How would I set up the spy to return a value based on the #AccountNumber selector?

Answer 1

You could try this:

var spy = ('#AccountNumber', 'ValueChanged');
$('#AccountNumber').trigger('ValueChanged');
expect(spy).toHaveBeenTriggered();
var val = $(spy.selector).val();

Update after edit: You could add this - Watch for object properties changes in JavaScript then inside handler trigger event 'ValueChanged', and on spy add listener to that event.
