Prototype - replace() Method

This method replaces element by the content of the html argument and returns the removed element.

Syntax

element.replace(html);

Here html can be either plain text, an HTML snippet or any JavaScript object, which has a toString() method.

If it contains any <script> tags, these will be evaluated after the element has been replaced.

NOTE − If no argument is provided, Element.replace will simply clear element of its content.

Return Value

Returns the removed HTML element.
