Form input type range element (Slider control)

Input Type Range

HTML5 gives us very useful slider control. Lets look at the syntax and how to use the slider control.

<input type="range" name="price" min="1" max="10" value="1" />

Here are the different attributes you can use with range input.

  • min: specify the minimum value allowed.
  • max: specify the maximum value allowed.
  • step: specify the value of the interval.
  • value: specify the default value of the slider.

You can use event onchange to track selected value.

<input type="range" max="10" min="1" name="quantity" value="1" onchange="alert('Selected value: '+ this.value);" />

HTML5 web storage – offline storage solution for the web

Using HTML5 you can store data into user’s browser. Before HTML5, there was only one way to store data using cookies. This web storage stores data in key/value pair. You can use this technique to store data offline.

How to check that browser supports web storage?

if(typeof(Storage) !== “undefined”)
// Browser supports web storage. So you can use local and session storage
// Browser does not support web storage.

There are two types of the web storage

  1. Local Storage
  2. Session Storage

Local Storage

You can store data into local storage like

localStorage.key = “value”;

And you can retrieve it as

var localStorageValue = localStorage.key;

This storage is persisted even you closes and reopen the browser.

Session Storage

This storage is same as the local storage. One thing differs from local storage is that, the data will be lost if user closes the browser. So if you want to store data per session, go with this storage.

You can store data as follows

sessionStorage.key = “value”;

After you can retrieve as

var sessionStorageValue = sessionStorage.key;

How to check/debug web storage is working or not?
