jQuery: simulate a user changing their choice for a <select>
This is only useful if you have a function to that reacts.
// make your function mySelectChanged() execute when the user
// changes the <select>
// Later in the code, whenever you want it do this
// to simulate the user making the change. Your function will execute.
This works for other types of input too. Like <input type=checkbox> etc
// onMyClick() will be called with user clicks.
// Simulate a click right away.
