What is decodeURI(), encodeURI() in JavaScript?

Answer

To send the characters that can not be specified in a URL should be converted into their equivalent hex encoding. To perform this task the methods encodeURI() and decodeURI() are used.

For example, the following code snippet performs the encoding of URL:

<script type="text/javascript">
          var uri = http://www.mysite.com/city?=Banglore; // original URI
          var ncodeuri=encodeURI(uri);
          document.write("<br />ncodeuri”);
          var dcodeuri = decodeURI(ncodeuri);
          document.write(“<br>/>dcodeuri”);
</script>
