jQuery Form Validation With Custom Select Box | Validate Form

How we can validate a form easily using HTML CSS and JS or jQuery? Solution: See this jQuery Form Validation With Custom Select Box, Validate Form.

Previously I have shared a few validation programs, but this one has a flat design and a custom select box. Basically, Form validation is for checking entered data locally before sending it to the server. If the data is incorrect, then the user will see a message to fix the problems. JavaScript provides a way to validate form’s input data on the user’s computer before sending it to the webserver. And this jQuery the work becomes easier.

Today you will learn to Validate Form using jQuery. Basically, there is a form with 4 inputs and a button. The first input for the name, second for the password, third for email, and the fourth one for select options, after these all there is a button to submit. There are many conditions like the name should be 6 characters, the password should be 6 characters, need a valid email, and an option must be selected. If you avoid any condition then you will see a specific message about fix that.

So, Today I am sharing jQuery Form Validation With Custom Select Box. There I have used jQuery for validation and HTML CSS for creating layout and styling. This is a registration form with basic fields, and it has a flat design. You can use it on your website after backend integration. This form has few input fields, if you can add more then you have to validate those.

jQuery Form Validation With Custom Select Box Source Code

Before sharing source code, let’s talk about it. First I have created the main div with class name container and placed all items inside it. Inside the container div, I have placed a text input for the name, an email input for mail id, a password input for the password, and a select tag with options. After that, create a submit button and another div for error/success messages. In the button tag, I have called the JS function which validating data using onclick="return functionName();" method.

Now using CSS I have placed all the items in the right place, as you can see in the preview. With CSS first I gave basic values like size, position, margin, padding, etc to the elements. There I have used transform and z-index commands to create a custom select box, there I have selected options separately using :nth-child() command. Also, I gave color values to the messages for error and success.

jQuery handling here whole validation function in the program, also it handling the custom dropdown select options. There I have used for loop for {} command and put other commands inside it to create the dropdown function. After that, used if{} else{} commands to validate and show messages according it.

Left all other things you will understand after getting the codes, I can’t explain all in writing. For creating this program you have to create 3 files. First file for HTML, second for CSS, and the third file for JavaScript. Follow the steps to creating this program without any error.
