The page I am working on has a javascript function executed to print parts of the page. For some reason, printing in Safari, causes the window to somehow update. I say somehow, because it does not really refresh as in reload the page, but rather it starts the "rendering" of the page from start, i.e. scroll to top, flash animations start from 0, and so forth. The effect is reproduced by this fiddle: http://jsfiddle.net/fYmnB/ Clicking the print button and finishing or cancelling a print in Safari causes the screen to "go white" for a sec, which in my real website manifests itself as something "like" a reload. While running print button with, let's say, Firefox, just opens and closes the print dialogue without affecting the fiddle page in any way. Is there something with my way of calling the browsers print method that causes this, or how can it be explained - and preferably, avoided? P.S.: On my real site the same occurs with Chrome. In the ex
If not, why would you ever use click
ReplyDeleteor bind('click')?
Because $.live() has some significant disadvantages
Live events do not bubble in the traditional manner and cannot be
stopped using stopPropagation or
stopImmediatePropagation. For example,
take the case of two click events -
one bound to "li" and another "li a".
Should a click occur on the inner
anchor BOTH events will be triggered.
This is because when a
$("li").bind("click", fn); is bound
you're actually saying "Whenever a
click event occurs on an LI element -
or inside an LI element - trigger this
click event." To stop further
processing for a live event, fn must
return false.
Live events currently only work when used against a selector. For
example, this would work: $("li
a").live(...) but this would not:
$("a", someElement).live(...) and
neither would this:
$("a").parent().live(...).
See this.
ReplyDeleteAs for why you would ever use click or bind instead of live, the answer is because you don't need the extra functionality.
You should read this very good answer in this similar thread:
ReplyDeleteIs binding events in jQuery very expensive, or very inexpensive?
Just a notice: there is a firebug extension which shows all attached events on a page: http://robertnyman.com/inline-code-finder/
