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.

<script type="text/javascript">


          var uri = https://www.mysite.com/city?=Banglore; // original URI


          var ncodeuri=encodeURI(uri);


          document.write("<br />ncodeuri”);


          var dcodeuri = decodeURI(ncodeuri); 


          document.write(“<br>/>dcodeuri”);


</script>
