HTML5 Form Attributes – Beginners Guide for Web Developers.
This tutorial is connected from the previous HTML5 tutorial, the “HTML5 Form Input Type Part II“.
In this tutorial, you will learn the new form attributes of HTML5.
We will tackle first about the placeholder attribute. The placeholder is a gray out text. The best part of placeholder is when you load your HTML5 content, it is not really your text in that text field, rather it is some sort of background or indication that your text field needs the appropriate text on that text field.
<input type=”text” name=”” placeholder=”Enter your name” />
After inserting this line of code to your input tags, your expected output should be like this.
Pattern and Required Attribute.
<input type=”text” name=”” placeholder=”Enter your name” pattern=”[a-zA-Z]*” />
Then, we are going to add another attribute which is the required attribute. Required attribute is a boolean attribute that lets your browser to know that the specific text field should be filled out, so if a user submits without filling out the required text field, your HTML5 website will prompt your user to fill out the required field.
Let’s add the required attribute and create an input submit type.
<input type=”text” name=”” placeholder=”Enter your name” pattern=”[a-zA-Z]*” required />
<input type=”submit” name=”” value=”Submit” />
After inserting the line of code to your HTML5 content, try to run your system and click the submit button. Your expected output should be like this:
Required attribute is really important especially to let your user know that the required text field should be filled out. Also, try to type numbers on your the required text field and you’ll receive an error message like this:
These form attributes are very useful when you create a website where you need to prompt your user to fill out all the fields needed for his/her information.
