javascript - Using jquery append method -

this question has answer here:

in code did like

$("#jdoe").append("<h3>test</h3>");

html

<html> <head> </head> <body> <div id="jdoe"></div> </body> </html>

it worked expected (the text test displays in h3), expecting if view source in browser see

<html> <head> </head> <body> <div id="jdoe"><h3>test</h3></div> </body> </html>

please correct me if expectations wrong

you haven't changed source of page, you've changed dom. if use developer tools preferred browser, you'll see changes there.

i think can developer tools browsers hitting f12.
