![]() ![]() *** Answer the question in your head now before you proceed ***Ībout half the replies to the Tweet were wrong. The task of these functions is to get the values of mins and secs from the page and return the equivalent integer value.A few weeks ago, I tweeted this interview question: Anyways, the last step is to add two more functions we used in the above function: getMinutes() and getSeconds(). They will equip you with all the knowledge you will need to grasp the concepts of this project. If you have any trouble understanding any of the concepts, you must check out our JavaScript Tutorial Series. Seconds = document.getElementById("sec") Minutes = document.getElementById("min") The function, as defined in the JavaScript file is as follows: You can alter the code and execute it, noticing what happens when you do so. We change the colour of the text, get an alert box and change the time displayed on the page. We’ve introduced various conditional statements that execute as the conditions change. The function acts differently when the time remaining is less than 10 seconds. ![]() Next, we will define the Decrement() function in the program that gets the location where we want to display the time in minutes and seconds. Time to revise the concept of JavaScript Functions The Decrement() function In this program, the method calls the Decrement() function after 60 milliseconds. The setTimeout() method in JavaScript calls a function or evaluates an expression after the specified number of milliseconds. The first thing we need to do is to define the variables and the countdown() function that executes as soon as the user clicks the image. This will help you easily understand what is happening. But before going to the complete code, I have split the content of the JavaScript file in sections. It’s amazing how many times we use JavaScript, isn’t it? We can achieve so much with just a few lines of code! So, let’s continue to the next step: adding JavaScript. But that isn’t what we want, now, right? Okay, so our countdown timer will work when we add JavaScript to our webpage. All it will do is show the page as above forever. This means that the timer will not actually work. Name this file as timer.css and save it in the ‘ css’ folder that resides in the current folder.Īfter adding CSS, our page looks something like this.īut the thing is, we only created a static website with HTML and CSS. If not, I would recommend you to do that first because we will not discuss the HTML and CSS content in this JavaScript tutorial. Hopefully, you are all familiar with CSS since you’re trying the projects. The code below contains a specific style, but I would ask you to play with it as much as you can. The second step in website creation is designing. ![]() Now it’s time to add some styling to our page with the help of CSS. Don’t forget to cross-check all the classes and ids you define in the files.Īfter adding HTML, the webpage will look something like this. All you need is to be careful while combining these files. Remember, you can add HTML and CSS as you wish to make the webpage more attractive. This is the only code you need to understand the working of a timer. Now, you can either use custom code or the following code to do so.Ĭlick the image to start the timer (60 seconds) In your text editor, save the new file with the name timer.html and start coding. The first task to creating any webpage is adding its HTML content. ![]()
