Project Study: Create A Common Register Form

I had shared my HTML Form study notes, and it is time to use those key elements to do a small form project. The Udemy course assignment is creating a register form like below:


There are a few requirements:
  • First name, Last name, Email are required fields
  • Password requires 5 to 10 characters
  • Three drop-down contents: Month, Day and Year
  • Three radio buttons: Male, Female and Other
  • One checkbox

Let's Start!

Step One: Use <label> and <input> to create First Name and Last Name fields


Before I create form, I start to enter page title "Register Form", and put header as "Register" under <body> tag. So when I open the page on browser, I can see the page is about "Register Form".

Then, I begin to create the form by enter <form> tag. The web application will know there will be a form under the page header. If you want to submit this form to another page, you need to add "action" and "method" attribute inside <form> tag.

For the first line, I create two <input> tags, one for "First name", and one for "Last name". Their types are "text" and required. Since the Form shows "John" and "Smith" inside the text box, so I add "placeholder" attribute for each <input>.We also want to add labels for each <input>, so users can understand what this fields stand for. 


Step Two: Create Radio Button


The second line of this form is selecting gender. Firstly, I add <div> tag to separate this segment to the first line. You can also use <p> tag to do the same thing.

Then, I add a type= "radio" attribute inside each <input> tags. Moreover, the web application needs to know each input stands for, so I add "value" attribute.

If I only write <input> elements, it only show three radio buttons on the form. People will have no clue what those buttons for. So, I add <label> tag with the right name for each <input>.


Step Three: Create "Email" field and Add validation message for "Password"


I add another <div> to start a new section for the form which includes "Email" and "Password" input.

For the email, I set the type attribute of the <input> element as "email", and add placeholder and required attribute, too. For the password,  I set the input type as "password" and add the placeholder. Don't forget to add labels for each field.

 

The assignment requires the password need to contain 5 to 10 characters. In order to do that, I search the solution online and learn to add pattern=".{5,10}", required title="5 to 10 characters" attribute value inside the <input> tag.


Therefore, when I fill in the form and just enter two characters in the Password field, after I click submit button, it pops up the error message. The message is exactly the information I added in the "required title "attribute.

Step Four: Create Drop-down Content

For the drop-down content, we need to use <select> and <option> tags. The first select content is "Month", so I start with <select name="Month"> tag, and add twelve months <option> tags. Then, I use the same way to create "Day" and "Year" drop-down fields. Again, Don't forget to add "Birthday" label at the beginning of the drop-down content.


The result will be:

Step Five: Add Checkbox and Submit Button

For the checkbox, we need to set the type attribute as "checkbox" in the <input> element. Since we want users to agree the terms and conditions before submit the form, I set name attribute as "agree". I have said hundred of times, add the label "I agree to the terms and conditions" for this checkbox, or nobody will understand what this single checkbox for.


At the end of the form, we need have "submit" button to allow users to click and submit the form. So I start a new line, and add a new <input type="submit"> element. The other way you can do this is add <button for "submit"> Submit </button> element. 


After I finished all the steps, the final form result is:


The form looks organized, clear, and easy to fill in. If you want encourage your potential customers to fill in the form or sign up for new account, the simple form design the better result.

My Story: A Mommy Start To Learn Code From Zero

From Google Image I am not a programmer, and I thought I would never become one. Everytime I see someone is coding, I think he or she must be very talent.  For me, coding is a very difficult subject to learn. Not only the language has so many rules, but also the logical reasoning behind the language is complex.  In my graduated school, I knew many friends who didn't have any coding background, but they are doing programmer or developer jobs now. Some of them went to school to study coding, and some of them  learned to code by themselves. Their stories are so impressive.  I wasn't ready to learn code until I finished my first Chinese book "留学，我的青春呀!" recently. I always want to be a writer and write my own book. I started writing blog three years ago, and I updated my post two to three times every week. As I enjoyed writing , I started to get some followers, likes, and good comments on my blog. Then, I decided to plan my first book. My First...
