a single button with dual functionalities

I am new to the development field and have a question about jQuery. I want a single button to perform two different actions. For example, let's say we have a button labeled Pause/Resume. When I click on the button, it should first display "Pause", and then when clicked again, it should display "Resume".

var flag = false;
$("#btn_pause_resume").click(function (){
if (flag)
{

alert("pause");
}
else
{
alert("Resume");
flag = true;
}

Answer №1

One method I really enjoy using is through attributes, specifically data attributes. For example:

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

Here's an example of how you can implement this:

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

A Handy Plugin

I recently created a plugin that simplifies this process:

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

You can add this to your code and use it like so:

$('#btn_pause_resume').toggleClick(
function () {
    alert('Resumed!');
},
function () {
    alert('Paused!');
}, true);//True makes second function run first

Try the Demo

This feature introduces a toggleClick function, where two functions are executed alternatively.

Your player now has a playStatus attribute

let playStatus = true; (indicating playback pause)
$("#playBtn").on('click', function(){
  playStatus = !playStatus;
});

You can now easily monitor the playStatus variable. if(playStatus){ alert .... }

Upon a close inspection, I immediately noticed that the click function was missing the closing parenthesis at the end of the code snippet. It is crucial to have this included for proper functionality. Additionally, the if statement should be specifically checking for false rather than any other value. I highly recommend using the strict triple equal comparison operator to ensure accuracy and efficiency.

With these adjustments in place, the code should now work seamlessly.

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