The unescape()
function is used to decode a string in JavaScript.
NOTE: The unescape()
function is outdated function in the JavaScript, instead of unescape()
function we are using decodeURI() & decodeURIComponent() in JavaScript.
<p>Click the below button to run the UnEsacpe function.</p> <input type="button" onclick="myFunction()" value="UnEscape(Decode)"> <p id="myId"></p> <script> function myFunction() { var u = "Want to learn technologies? Go through TechFunda.com"; var v = escape(U); var d = unescape(E); var r = "Encode Result is:" + E + "</br>" + "Decode Result is:" + D; document.getElementById("myId").innerHTML = R; } </script>
In the above code snippet we have given Id
as "myId
"to the second <p>
element in the HTML code. There is a function myFunction() in the<script>
block which is connected to the onclick of the HTML button and there is a string with value "Want to lear technologies? Go through TechFunda.com" to the variable u
, we need to decode the u
variable, for that we are using unescape()
function in Variable d
(Although at eunscape()
function is not used in JavaScript, for expalining the code we are using unescape()
function). To decode a string we need the encoded string, for that first we are usnig escape()
function to encode the string in varaible e
, and then unescape()
function to decode the encoded string. Onclick of the button "UnEscape(Decode)" in the HTML code fires the function myFunction() in the <script>
block at the same type unscape()
function decodes the encoded string value and returns as output.
