jQuery html() method is used to set or return the content of the selected elements.
When html() method is used to set the content of the selected elements, it overwrites the content of all the matched selected elements. For example, the code $("p").html("BeginnersBook"); will change the content of all the paragraphs to “BeginnersBook”.
When html() method is used to return the content of the selected elements, it returns the content of the first matched element and ignores the rest. For example, if there are multiple paragraphs on a page then the code $("p").html() would return the content of first paragraph only.
jQuery html() Syntax
To return the content:
$(selector).html()
To set the content:
$(selector).html(content)
