How to stop .click function being fired many times if user clicks many times

Question

How to stop .click() function being fired many times if user clicks many times.

Here is my code

$("#loadme").unbind('click').click(function() {
  hello();
});

If the user clicks on #loadme many times the function will repeat again and again. I want it to stop firing it many times.

Answer 1

You seem to want one :

$("#loadme").one('click', function(){
   hello();
});

Answer 2

var clicked = false;

$("#loadme").unbind('click').click(function(){
    hello();
    clicked = true;
});

function hello(){
    if(clicked){
        //do nothing because it was clicked more than once.
    }else{
        //your code
        clicked = false; //reset
    }
}

Answer 3

You can do :

$("#loadme").on("click",function(){
    $("#loadme").off("click");
    hello();
});
