JQuery - check if first click

Question

I have 2 functions (A and B) called with one click div. I need to call function A only on the first click and function B whenever it is pressed. How can i do this?

Answer 1

A simpler solution:

$('element').one('click',function(){
// Call A
}).click(function(){
// Call B
});

Answer 2

You can use . one () for your first function and , as usual, for your second function .click()

function a() {
    console.log('Fire once!');
}

function b() {
    console.log('Always fired!');
}

$('span').one('click', function() {
    a();    
});

$('span').click(function() {
    b();    
});

$(function(){
    $("selector").on("click",FunctionA);

    $(this).on("click",FunctionB);
}
