Today lets see how we can make use of pattern attribute to validate the user input data and use title attribute to hint the user for right inputs.
HTML file
index.html
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 | < !DOCTYPE HTML>
<html>
<head>
<title>pattern and title attribute: HTML5</title>
<link href="myStyle.css" rel="Stylesheet"/>
<meta charset="utf-8"/>
</head>
<body>
<form>
<label for="name">Name: </label>
<input id="name" type="text" pattern="^[a-zA-Z]+$" title="Example: Satish"/><br />
<label for="age">Age: </label>
<input id="age" type="text" pattern="^[0-9]{2}$" title="Example: 25" /><br />
<input type="submit" value="Done"/>
</form>
</body>
</html> |
Here in the first input field, we’re restricting the input to only lower case and upper case alphabets. To the second input field, we’re restricting it to only 2 digits from 0 to 9.
CSS file
myStyle.css
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | label{
width: 50px;
float:left;
}
input{

}
form {
padding: 5px;
background-color: ivory;
width: 300px;
