X'); / / this feature is equivalent to the code commented in body $('body') .append (oLogin); oLogin.css (' left', ($(window). Width ()-oLogin.outerWidth ()) / 2); oLogin.css ('top', ($(window). Width ()-oLogin.outerHeight () / 2); / / the pop-up window can appear in the middle of the browser $("# close") .click (function () {oLogin.remove ()) }) / / window does not need to be quoted in $() in jquery / / add resize () browser window size change / / scroll (): scroll bar, the following function is that when the scroll bar scrolls, the position of the pop-up window does not change $_ (window) .on ("resize scroll", function () {oLogin.css ('left', ($(window). Width ()-oLogin.outerWidth ()) / 2 scroll $(window). ScrollLeft () OLogin.css ('top', ($(window). Width ()-oLogin.outerHeight ()) / 2) $(window). ScrollTop ();});})

Points used:

JQuery creation: $('')

The position of the pop-up window:

OLogin.css ('left', ($(window). Width ()-oLogin.outerWidth ()) / 2); oLogin.css (' top', ($(window). Width ()-oLogin.outerHeight ()) / 2)

When the scroll bar scrolls, the position of the pop-up window changes:

$_ (window) .on ("resize scroll", function () {oLogin.css ('left', ($(window). Width ()-oLogin.outerWidth ()) / 2 million $(window). ScrollLeft ()); oLogin.css (' top', ($(window). Width ()-oLogin.outerHeight ()) / 2 million $(window). ScrollTop ();}) this is the end of the introduction about "how jQuery achieves pop-up window effect". Thank you for reading.
