Basic JavaScript Question:
Explain unescape() and escape() in JavaScript?
Answer:
These are similar to the decodeURI() and encodeURI(), but escape() is used for only portions of a URI.
<script type="text/javascript">
var myvalue = "Sir Robbert Scott";
document.write("Original myvalue: "+myvalue);
document.write("<br />escaped: "+escape(myvalue));
document.write("<br />uri part: "&author="+escape(myvalue)+""");
</script>
If you use escape() for the whole URI... well bad things happen.
<script type="text/javascript">
var uri = "http://www.google.com/search?q=Online Web Tutorials"
document.write("Original uri: "+uri);
document.write("
escaped: "+escape(uri));
</script>
<script type="text/javascript">
var myvalue = "Sir Robbert Scott";
document.write("Original myvalue: "+myvalue);
document.write("<br />escaped: "+escape(myvalue));
document.write("<br />uri part: "&author="+escape(myvalue)+""");
