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.

	{
		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.
