javascript - one button two different actions -


i'm new development section . have small clarification in jquery . single button should possess 2 different action . let consider button name pause/resume if click on pause button should alert pause clicking on same button has display resume .

var flag = false; $("#btn_pause_resume").click(function (){ if (flag) {  alert("pause"); } else { alert("resume"); flag = true; }

my favorite way use attributes (data). kind of like:

<button data-paused="false"></button>

here's solution:

$('#btn_pause_resume').click(function () {     if ($(this).data('paused')==='false') {         alert('resumed...');         $(this).data('paused', 'true');     } else {         alert('paused...');         $(this).data('paused', 'false');     } });

demo

quick plugin

here's plugin wrote make easy:

$.fn.toggleclick=function(t,a,e){$(this).data("togglestate",e||false),this.click(function(){"false"===$(this).data("togglestate")?(t(),$(this).data("togglestate","true")):(a(),$(this).data("togglestate","false"))})};

add top of code , can do:

$('#btn_pause_resume').toggleclick( function () {     alert('resumed!'); }, function () {     alert('paused!'); }, true);//true makes second function run first

demo

this adds toggleclick function. function takes 2 functions each run.
