The replace() method is used to replace some characters with some other characters in a string. stringObject.replace(findstring,newstring)

stringObject.replace(findstring,newstring) findstring: Required. Specifies a string value to find. To perform a global search add a 'g' flag to this parameter and to perform a case-insensitive search add an 'i' flag newstring: Required. Specifies the string to replace the found value from findstring Note: In the following example the word Microsoft will not be replaced (because the replace() method is case sensitive): <script type="text/javascript">           var str="Visit Microsoft!";           document.write(str.replace(/Microsoft/, "W3Schools")); </script> Example 2 - Case-insensitive Search In the following example we will perform a case-insensitive search, and the word Microsoft will be replaced: <script type="text/javascript">var str="Visit Microsoft!";           document.write(str.replace(/microsoft/i, "W3Schools")); </script> Example 3 - Global Search <script type="text/javascript">           var str="Welcome to Microsoft! ";           str=str + "We are proud to announce that Microsoft has ";           str=str + "one of the largest Web Developers sites in the world.";           document.write(str.replace(/Microsoft/g, "W3Schools")); </script> Example 4 - Global and Case-insensitive Search In the following example we will perform a global and case-insensitive match, and the word Microsoft will be replaced each time it is found, independent of upper and lower case characters: <script type="text/javascript">           var str="Welcome to Microsoft! ";           str=str + "We are proud to announce that Microsoft has ";           str=str + "one of the largest Web Developers sites in the world.";           document.write(str.replace(/microsoft/gi, "W3Schools")); </script>
