Jquery: Append Div Only Once 'on Click'

I am trying to append a section to a div on the click of a button. I want the section to be appended only on the first click, the code that I use below appends a section every tim

Solution 1:

You could use one(), which fires only once

$("#nextractorapply").one('click', function () { 
    // executes only once

     $("#main").append('<section id="nextractor" class="five"> </section>');  
});

$("#nextractorapply").on('click', function () { 
    // executes every time// do other stuff
});

Solution 2:

Use a conditional to determine if it's there.

$("#nextractorapply").click(function () {
    if($('#nextractor').length < 0){
        $("#main").append('<section id="nextractor" class="five"> </section>');
    }  
});

Solution 3:

You can use some kind of a condition that prevents its appending multiple times.

var counter=0;
$("#nextractorapply").click(function () {
    if(counter<=0){
        $("#main").append('<section id="nextractor" class="five"> </section>');  
        counter++;
    }

    //YOUR OTHER STUFF THAT YOU NEED TO EXECUTE ON EVERY CLICK
});

Solution 4:

You could use .unbind()

$("#nextractorapply").unbind().click(function () {
    $("#main").append('<section id="nextractor" class="five"> </section>');  
});

Solution 5:

You could set a variable and fire event if variable is set as true or false.

var _clicked = false;

$('.element').click(function(){
  if(!_clicked){
   _clicked = true;
   console.log('event fired');
  }
})
