How replace method works in jQuery?
The replace() is the method that is used to replace the user contents on the application that is it converts one type of value to another type with the data type like string, number, text, etc. Actually, the replace() method is removed the contents from the specified DOM(document object model) then it can be placed the new value on the same area with the single cells. This is the DOM structure of the replace() method on jQuery. Mainly the selected elements replaces the target value by moving the old location that can be inserted on the specific region it’s not being moved cloned on all the areas. We used parallel methods like replaceWith() method it matches all the elements with specified DOM and HTML elements. jQuery replace() is also one of the function of the string it can be replace the string tag values and left it on the markup. It is also the code will be get more complicated but it might be find out the reading of the user input values. The jQuery code snippet is mainly occurrences for all the characters strings that will be replaceable one before that it needs to find the strings and then it can be replaced.

</P>
</div>
</body>
</html>Sample Output:

Example #3
Code:
<!DOCTYPE html>
<html>
<head>
<title>Welcome to My Domain it’s a third example</title>
