Browsers which support range input type know that the field is used for entering a number with in a given range.
User Interface(UI) enhancement wise, you may get a slider control to select a range of number. You can even use min, max and step attributes to provide additional control for the field – for setting the range.
HTML file
index.html
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | < !DOCTYPE html> <html> <head> <title>range Input Type: HTML5</title> <link href="myStyle.css" rel="stylesheet" /> <script src="myScript.js"></script> </head> <body> <form> <label>Range(2 to 10): </label> <input type="range" min="2" max="10" id="get" step="0.2" onchange="fetch()"/> <input type="number" min="2" max="10" step="0.2" id="put" /> <input type="submit"/> </form> </body> </html> |
Here we have 2 input fields of type range and number respectively. Both having minimum allowed value as 2 and maximum allowed value as 10, and a step of 0.2 (fractional value). The number input field is taken for the sake of illustrating the value selected by the user using the range input field – by using(sliding) the slider.
JavaScript file
myScript.js
1 2 3 4 5 | function fetch()
{
var get = document.getElementById("get").value;
document.getElementById("put").value = get;
} |
Here we fetch the value selected by the user using the slider and assign the value to the number input field.

Note: Browsers which do not support range input type, simply fall back to text input type. However, you need to validate the user entered data at server-side for more security. Client side validation is done mainly for the sake of creating the illustration of speed of validating the data and for a better user experience.
