JQuery :: CrSpline - Animates Elements Smoothly Along Arbitrary-length Sequences Of Waypoints In 2D?
Jul 28, 2010
jQuery.crSpline - Smooth 2D animation along paths of multiple waypoints, using Catmull-Rom splines.
Demo GitHub You provide: A series of (x,y) points that the path should follow. Plugin provides:
Animation along a smooth 2D path that intersects all points. Check out the demo page to see what it looks like.
[Code]...
I just published an early release of this and am looking for feedback from other developers! I made it because I needed an easy way to make animations out of extended sequences of coordinates (without doing the math to stitch together bezier curves), and as far as I could tell no one else had published an easy method to animate along Catmull-Rom splines using jQuery. This is the result, and the hope is that it will be super easy to use and helpful for people besides just me.
Future plans: More general animations and customizable behavior. The current version only animates top and left properties along whole pixel values. It also assumes that every segment of the path should take equal time, resulting in some strange speed changes when moving from small to large segments. Currently brainstorming good fixes for all of these.
I'm trying to figure out how to make something happen only if there are more than one link inside a div.[code]For now I'm trying to make the little div with the class "cover caption" NOT move when there is only one link in the div.THe reason for this is that I want the whole div to be clickable if there is only one link inside.
I am trying to do a simple check-all / un-check-all checkbox system. All of the solutions I have seen use "this.form.elements.length" or a variant of this.
My scripts don't work because "this.form.elements.length" always returns 0. Example:
I don't know if this is a browser bug. I positioned a div at the bottom of the page just underneath the viewport, calculating it with $(document).height() and animate it to bottom:0, works great even when scrolling, cause of updating with the scroll-event. But when I reload this page or scroll down a bit the original position value was used, so it animates to the original viewport value.
I've been looking at this for a while now and I just can't get my head around it. What i need to do is put together a program which allows the user to type in a sequence of letters and then tells the user how many times they have included the letter 'a' in their sequence. So far i have put this together but the output is totally wrong at the moment and it often either just says 1 or 4. Code:
To synchronize the vertical scroll of the following "left" and "right" divs only when the beginning and end of each "blahN " div is reached inside the left div. Both divs have a finite height, which basically insures that the scroll bar will be present. The left div outputs text-based content from various database procedures while the right div outputs images corresponding to the text. The text is nothing more than pages from the website and as you can see inside the left div, each is encapsulated within a subsequent div with an incremental class (i.e.- "blah1", "blah2", and so forth.) When one scrolls through each "blah" content inside of the left div, I would like the right div to output the image that corresponds to the text (again, this data comes from the website through previous transactions.) Here's an example: John Doe comes to the website and starts reading the various pages listed inside the left div.
There might be 2 pages loaded inside the left div, or, there might be 20, but in any event, when he loads the entire page containing all this, the first page will be displayed along with the first pages' image. When he scrolls past this first entry (page) inside the left div, the corresponding image related to it inside the MySQL database is then output as well over in the right div and so on with every other "blahN " piece of content. Right now, the jQuery I'm using has synchronized both divs to scroll at the same time, regardless of specific waypoints that might be reached per-scrolling.
Here's the basic markup I'm using right now:
<div class="left"> <?php foreach($obj->field_page_objs as $k1=>$v1){

few other websites and the responsiveness has been minimal-to-nonexistent. I'm sure this is because of both how I've explained the problem combined with the overall difficulty (or niche-ness) it introduces. In any event, I apologize beforehand if this carries over into this website.
I am trying to read a file with hundreds of entries such as this one:
Code: <wpt lat="32.491507027298212" lon="-94.35264403000474"> <name>20 W & 617</name> <sym>Waypoint</sym>
[Code]....
and will delete the wpt entry if the location is out of range. The problem is the file may not be formatted in that there may not be any or or extra space between fields.
I can set up a regexp to identify a wpt entry and look at the lat and lon values but need to know how to set up a loop to delete an entry if needed and continue from there until all entries have been looked at. The data will have been copied into a textarea and from there into a string variable.
I have a slideshow that I built, and all is good. However, I want to arbitrarily change a slide once the slideshow is underway, and I don't see a mechanism to do that.
I have tried to write two simple functions to achieve this:
function exposeReplaceSlide(opts, els) { $.fn.cycle.replaceSlide = function (newSlide, location) { realReplaceSlide ( opts, els, newSlide, location);
[Code].....
but this doesn't seem to do the trick...it can locate the slide position, but the insert of the slide doesn't work...I get a blank slide in place of the html I want to insert.
I'm trying to make a Javascript application that animates a ball bouncing up and down. I have five image files (ball1.jpg, ball2.jpg, etc located in the same folder as my html file. Here is my code:
[Code]...
My code also has all of the text which makes it xhtml in the beginning which I didn't type out. When I open the html file in Chrome, I see the first picture and the Start Animation button but when I click the button nothing happens.
I'm using Jquery API slideUp and slideDown for my site when i click on a group of channel, a list of it's detail will appear as slideDown slowly and the others will disappear slowly. At first element i click it work fine, but from the second element it just disappear and appear not slide up or slide down. You can see it at URL :
I have a site that made extensive use of javascript event handlers embedded in the html. I am trying to port the code to jquery and I notice that after the conversion, pages don't scroll as fast or smoothly as they did before. I actually notice this on many sites that make use of jquery or some other jscript library. What causes this behavior, and is there anything that can be done to minimize the sluggishness of the site?
Can anyone suggest how to create an arbitrary object at runtime WITHOUT using the deprecated eval() function. The eval() method works ok (see below), but is not ideal.
function Client() { } Client.prototype.fullname = "John Smith"; var s = "Client"; eval("var o = new " + s + "();"); alert(o.fullname);
Note: I want the type name of the object to be represented as a string (in this case "Client" -- this is a non-negotiable requirement).
I also tried the following (which appears to fail):
function Client() { } Client.prototype.fullname = "John Smith"; var s = "Client"; var o = new Object(); o.construct = s; alert(o.fullname);
eval() is handy but not future-proof, so any suggestions would be welcome.
- works as expected in that one photo fades into the next photo smoothly. Test page looks great - [url]
However, when I put the exact same code into Thesis/WordPress, I get a long delay between the images, and spend several seconds looking at a blank stage - [url]
Why would that be? How to make the images transition fade smoothly into the next image
how to properly add some text content before and after a user's selection?I am working with the TinyMCE editor, and I can get the following from it:
* User's selection as a W3C compatible range * User's selection as a browser selection object * User's selection as a node (element) that encompasses the user's selection
I also need the user's selection to remain selected after being wrapped.I've looked all over the web and could find nothing (except running into my OWN previous questions about this).Here's an example of what I'm trying to do:
[URL]
First line is original text, second line a part is selected, third line the selection is wrapped and the selection remains selected.
I've created this sliding panel where I click the Sidebar button and it slides out or in. But I would like to make it run more smoothly. I tried storing references to the elements within the MoveSidebar() as this.variables, so that they wouldn't be re-defined each time, but then FF spits out that 'this.sidebar.style' is undefined?!
How can I make it run more smoothly, or get FF to recognise 'this.sidebar.style' (once I reinstate all the this.references)? Here's the whole page and the button is also attached for ease of testing.
I am trying to make this page work where new posts that get posted to it append smoothly on refresh instead of sliding up and down like they do now. Right now, you hit reply on your post and the entire thing goes up then unfolds again with the new post there, but the place is lost where you were on the paeg and you have to scroll down and I think that is not that user friendly. I want it to just pop or slide down under the existing posts so that the place on the window isn't lost for the user.
The profile page is here. I am talking about the profile threads. It's a little bit like a facebook wall. If you need more info I will try and get it.
I want to code a site that will scroll to anchers smoothly on a webpage in a horizontal direction. It seems like it should be pretty easy to just modify the code in the article "Make Internal Links Scroll Smoothly with JavaScript" (http://www.sitepoint.com/article/scr...hly-javascript). Since I'm pretty new to coding java I was wondering if someone would be able to show me how to rewrite this code to get it to work in the horizontal direction.
But it seems that you can only move the boxes if you click them and then move them really really fast, otherwise they don't react... I looked at the js file but I can't figure out what to change in order to make the boxes move more smoothly...I can't place the js file because its to big...
I'm using a JQuery function to slide a div into and out of visibility, but every time I toggle, the browser resets my view to the top of the web page..What I want to happen is when you click to reveal the div, the page scrolls down and the div content is in full view. When I click again to re-hide the div, I want the page to scroll back up smoothly instead of just reverting to the top of the whole page...The page url is: http:[url]....Here's my code:
I have a standard ul list where I need to keep count of the li's within (users can add/remove). This is my function when they remove a list item (.remove is inside the li), it removes the li fine but I always get zero for the rows.
Internet Explorer (in particular IE6) has some limit on maximum URL length. This is very hard to debugging if you don't know what to search for. Maybe jQuery could throw some self-explaining exception when URL is too long?
I'm brand new to jquery, and am trying to set up a dynamic navigation dropdown which is populated with XML by our system (which I can't change.) For some reason, IE6 is showing space where the unused <li></li> tags are. I am trying to create a jquery code which will detect whether or not a link is present in the <li> so I can turn the display off or on dynamically. The relevant jquery code is here:[code]It should eventually appear like this, the way it does in Firefox due to CSS styling:[code]Which means that somehow, it is reading the <a> even when there isn't one.
