How to make a single button radio button in jQuery?

Question

JavaScript

There is one button. It is necessary that on one click one function was performed, and on repeated - another function was performed. How to implement*?

Answer 1

Easy option

var i = 0;

$('button').click(function() {
    i++;

    if (i == 1) {
        // function 1
    } else {
        // function 2
        i = 0;
    }
});

Answer 2

Create a variable and check its value when the button is clicked. Depending on the value of the variable, perform some action and change the value of the variable.

Answer 3

you write

(function($) {
    $.fn.clickToggle = function(func1, func2) {
        var funcs = [func1, func2];
        this.data('toggleclicked', 0);
        this.click(function() {
            var data = $(this).data();
            var tc = data.toggleclicked;
            $.proxy(funcs[tc], this)();
            data.toggleclicked = (tc + 1) % 2;
        });
        return this;
    };
}(jQuery));

then you use

$('#test').clickToggle(function() {   
    // Функция 1
},
function() {
    // Функция 2
});
