Best way to remove an event handler in jQuery?

Question

I have an input type=\"image\". This acts like the cell notes in Microsoft Excel. If someone enters a number into the text box that this input-image

Answer 1

All the approaches described did not work for me because I was adding the click event with on() to the document where the element was created at run-time:

$(document).on("click", ".button", function() {
    doSomething();
});

My workaround:

As I could not unbind the ".button" class I just assigned another class to the button that had the same CSS styles. By doing so the live/on-event-handler ignored the click finally:

// prevent another click on the button by assigning another class
$(".button").attr("class","buttonOff");

Hope that helps.
