Question

How to detect if a click() is a mouse click or triggered by some code?

Answer 1

Use the which property of the event object. It should be undefined for code-triggered events:

$("#someElem").click(function(e) {
    if(e.which) {
        //Actually clicked
    }
    else {
        //Triggered by code
    }
});

Here’s a working example of the above.

Update based on comments

Pressing the Enter key when an input element has focus can trigger the click event. If you want to distinguish between code-triggered clicks and all other clicks (mouse or keyboard triggered) then the above method should work fine.
