You may have noticed that in some forms, as soon as you enter an invalid email address, the form gives an error "Please enter a valid email". What are the different types of form validations?įorm validation can happen on the client side and the server side.Ĭlient side validation occurs using HTML5 attributes and client side JavaScript. Malformed or missing data can also cause the API to throw errors.
We must ensure that the data entered is in the correct format, lies within a valid range of data (such as for date fields), and does not contain malicious code that could lead to SQL injections. We need form validation anytime we are accepting user input.
So it's important that the data collected from those forms is cleaned, formatted correctly, and devoid of any malicious code.

Some apps use forms to collect data to sign up users and provide an email address.
So we have successfully able to change HTML5 audio player src file in JavaScript and then add the functionality to our button.Forms are ubiquitous in web applications. If you test it on the browser, you will see that clicking the buttons will change the audio file and it will instantly start playing the new music as we have called the JavaScript play() method. After that replace the audio file path for both the button functions parameters and audio tag. You can save the above code as an HTML type file.
So actually we just have to change the src file of our HTML5 audio player and it changes the audio. In our code we take the advantage of the setAttribute() method to change the audio file of our HTML5 audio player. In the above snippet, we have used the JavaScript setAttribute() that used to change the attribute of any HTML element. You can change the audio file of the HTML5 player with just one line of JavaScript code that you can see below: document.getElementById("my-audio").setAttribute('src', 'AUDIO_SRC_FILE') It is quite easy to change the music file of an HTML5 audio player with JavaScript. In this post, I am going to show you how can you change HTML5 audio player src file in Javascript.
