Yahoo! Mail and GMail both has a checkbox on top of their email list which will “checked” all chekboxes when clicked. Previously I use plain old javascript like those in this link, I just try to use jQuery to do this, its only 5 lines
$('#selectAll').click(function(event){
$('input[type="checkbox"]').each(function(){
this.checked = event.target.checked;
});
});
I was about to create a file upload form and want to check whether user has choose a file or not. I have tried using
if (typeof(variable) == 'undefined' || variable == null)
then
if (variable == null)
and many other way, just got luck when using
var filenames = $('#userfile')[0].files;
if (filenames.length > 0)
Here are 70 Javascript Libraries I’ve found from some articles and a bit googling
document.getElementById(FrameID).contentDocument.location.reload(true);$('#currentElement').attr("src", $('#currentElement').attr("src"));3 ways:
<script src=”http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js” type=”text/javascript”></script>
<script type=”text/javascript”>swfobject.embedSWF(“‘ http://www.youtube.com/v/YOUTUBE_ID ‘”, “banner1 ‘”, “480”, “385px”, “9”);</script>
