JQuery animate border without moving div

阅读更多关于 JQuery animate border without moving div

问题 I want to animate a div by first making it's border thicker by 5px on mouseenter, then decreasing the border by 5px on mouseleave, the tricky part is that I don't want the div to look like it's moving (if you just animate the borders, the whole div will look like it shifts, not just the border getting thicker/thinner). I'm very close, but I'm stuck on the last part: mouseleave. What I have so far is: $("#thumbdiv<%=s.id.to_s%>").bind({ mouseenter: function(){ $(this).animate({

jQuery, calling a callback only once after multiple animations

阅读更多关于 jQuery, calling a callback only once after multiple animations

Let's say that I have several animations running at once, and I want to call a function once all of them are finished. With only one animation, it's easy; there's a callback for that. For example : $(".myclass").fadeOut(slow,mycallback); Trouble is, if my selector finds several items, the callback will be called for each of them. A workaround is not too hard; for example : <!DOCTYPE html> <html> <head> <title>Example</title> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.js"></script> <script type="text/javascript"> $(document).ready(function() {

问题 I'm looking to animate a div element from an absolute top position to an absolute bottom position on the page load. The combination of CSS and jQuery code below fails to move anything: CSS #line-three { position:absolute; width:100%; left:0px; top:113px; } jQuery $("#line-three").animate({ bottom: "100px", }, 1200); Thank you for your help!

问题 I have an Options box that hovers in the top right of the webpage. It's opacity is set to 10% so as not to be obstructive to users. When they hover over (mouseenter) it I use jQuery to fade it in and slidedown the content (and the reverse on mouseout). If they do this repeatedly though the animation stacks up and you can sometimes be left in a situation where your mouse is stood still but the box is yo-yoing around. How can I get around this situation? Here is how I currently setup the

Do you want to fade the

问题 To be short, I am looking for a jQuery loop that will select each div with a class (approx 10 small divs in a line) then execute some code on each div specifically fade out and in the image contained in the div and then pause and move on and do the same to the next div.
