p5.js | html() Function

The html() function is used to set the inner HTML of the element by replacing any existing html. If the value of the second parameter is true then html is appended instead of replacing the existing html element. If this function does not contain any parameters then it returns the inner HTML of the element.

Note: This function requires the p5.dom library. So add the following line in the head section of the index.html file.

<script language="javascript"
    type="text/javascript" src="path/to/p5.dom.js">
</script>

Syntax:

Parameters:

• html: This parameter holds the HTML element in string format which needs to be placed inside the element.
• append: This parameter holds the Boolean value to append existing HTML element.

Return Value: This function returns a string which contains the inner HTML of the element.
