I have been using the replace function since long to remove the classes from JavaScript, Now I was making the JavaScript function for that through which, I can pass an element and the class name to remove the class from the same.

changeAddress.className = changeAddress.className.replace(new RegExp('(?:^|\\s)' + 'hide' + '(?:\\s|$)'), ' ');

Or

document.getElementById("MyID").className =
    document.getElementById("MyID").className.replace(/\bMyClass\b/,'');

So can someone suggest me how to pass the class "hide" and "MyClass" Dynamically in the same?

    The answer to your literal question is here: [Javascript Regex: How to put a variable inside a regular expression?](http://stackoverflow.com/questions/4029109/javascript-regex-how-to-put-a-variable-inside-a-regular-expression). However, there is a much better solution for the actual problem you are trying to solve. – Felix Kling Jan 10 '17 at 07:06

To remove the class from an element, use classList API

document.getElementById('MyID').classList.remove('MyClass');

    Seems like a conflict between answering the literal question (or closing as a duplicate in this case) and providing the right solution to the problem :-/ Good answer! Feel free to reopen the question. – Felix Kling Jan 10 '17 at 06:04
