<bo开发者_JAVA百科dy> Enter your string here:<input
type="text" id="inputstring"><br>
Enter new string here:<input
type="text" id="newstring"><br> <input
type="button" id="replace"
value="Replace"><br>
<p id="para">This is the new paragraph
written to test how to replace the a
string with desired string</p>

You need to use ignorecase flag for the regular expression.
para.replace(new RegExp(oldstr, 'i'), newstr
