JQuery :: Jerky Animations When Using Php To Create Animated Content
Jan 12, 2010
This is a weird one. I have a page I'm working on, and I made a simple div that slides up to display some content, then slides down, replaces the content and slides back up again. Basically a showy news ticker.
When I created the div/animation code it ran fine. smooth as silk. However, I then decided to move that part of the html into a templated system, where some php reads a second file and outputs the contents into the webpage. (real simple stuff, it uses file_get_contents and echo to output the file contents).
Using this system, it all displays correctly, but the animation is suddenly slow and jerky. This doesn't make sense to me. Why would the animation suddenly become jerky just because the html that creates the divs is now created via php? Surely the php fires long before jquery gets involved - so why would this occur?
How to create animated Neon Sign Board using jQuery? I want to create it only with text without using images. Is it possible to create using text shadow?
I have an onclick that triggers ajax which calls a php script to pull data from MySQL. This information is then displayed in a div. The problem I am having is that sometimes pulling the data from MySQL takes 2-3 seconds, so the div is empty for about 2-3 seconds. How would I go about adding an animated "Loading" gif to display in the div while it is waiting to display the content?
I'm trying to create a scrolling menu. Example here [URL] I don't think there's an issue with the javascript necessarily. I've tried alternatively using jquery's animate function with scrollLeft and I still get the flickering. I'm thinking it's more to do with the HTML/CSS. For instance I'm wondering if using a table instead of a floated list for the menu might be a step in the right direction.
I am using the following code for my banner. I have got 6 set up. what I want to do is specify the time each one appears for. I can chnage this for all of them but I want to set them indivdually?
I wanted to start my research on the topic of slideshows here and ask if anyone knows what's the best method for creating a slideshow that should have the ability to display images and videos (and bookmark them)? It can be a plug-in, but this is for a client so it has to be okay for commercial use (and free).It should also be able to support other content like ads and polls/questionaires, in the form of a div. Also HTML 5 compatible with all the cross-browser compatibility one would expect.
I am trying to create portlets that dynamically load their content (usinq jQuery). My first approach was to leave the header + footer + decorations of the portlet OUTSIDE of the dynamically loadable content. It worked just fine but I had to abandon that approach so that I could use the same code both for statically- and dynamically-loaded content (e.g. when no AJAX support was available). So far so good.
Now to my problem: I use the following code for loading my dynamic content
The loading works fine, but after the dynamic content has been loaded I can not seem to get access to it using jQuery!
Short description: Line 3 clears the content (I know! There are better solutions!) Line 4 loads the content Line 6 dumps the data on the console; this is for debuging only, so that I can establish that the correct content is loaded
After the data is properly loaded I did expect to be able to find it by traversing the DOM tree in traditional jQuery fashion (like in Line 10). However, dumping the contents of the 'tag' shows it containing no content at all; it is empty even though the browser renders the expected new result. I thought: Well! The browser holds two copies of the DOM tree; one that is the original page and one that is the modified content used for rendering". Therefore I attempted to manipulate the loaded content within the function (Line 8). The content is visible there, that I have established in Line 6. But I do not know how to access it jQuery-style.
(Why am I trying to modify the loaded content? I want to inject a title row with various decorations and clickable content.)
1. first I have a link for something that works but I want to work better:
[url]
The dynamically resizing textarea boxes are in light orange. They work, but they are rather jerky and you see some "bounce" when adding or removing lines -unlike Face Book which doesn't do this. Can anyone propose a better coding system that is smoother AND less processor intensive?
2. If you really do UNDERSTAND javascript at the programmatic level I'd be interested in having you work regularly for me, but I think I might need to post that in another forum. I'm a PHP programmer, and because I don't understand the JS Kernel and how it thinks, I'm always chasing my tail on it.
And what this is doing is when a mouse is put over my div 'hireMe', the background position is animated upwards and in fades in my text with an id of 'resume'. However if halfway though the FadeIn you move the mouse out of the container, it will permantly be stuck in this limbo world and will never return to 100% opacity again. Am I utilizing the stop() properly?
This is the website that is in question. Below is the script that I think is causing the problem. Every time you navigate to a new page I want the pages to fade out/in. However, there is a brief blink in between animations. I have tried to use stop() and not, but neither seems to help. I will post both options.
I want to animate a button with .hover and then animate it even more with .click. The problem is when the button is clicked, the mouse is no longer hovered so the hover returns to the default position. I need to stop the .hover from returning to the default non-hover state when the button is clicked.
I taught it to myself without even having any true JavaScript experience and am sure that while functional, many of my implementations could/should be written completely differently. I'm running some animations that look great in everything except for IE. In IE I'm seeing a thin, ragged black border around some of the elements that I'm animating.
I have some code that executes two animations when the user clicks on an area. I want both animations to go off at the exact same time, however from time to time it seems as if one will be triggered first and then after a slight delay the second one will be triggered. This, of course, is noticeable and a problem. How can I ensure that they will go off together?
I have applied the fadeIn() and fadeOut() effects to a li>ul in my html, but if the user leaves the ul briefly then re-enters it before it has finished fading out, the ul fades back in again. This can happen many times over by accident and it's very annoying.
If the user leaves the ul I want it to fadeOut() and NOT fadeIn() again until the user re-enters the parent li element.Is there a way of ensuring this? I have done a quick search for while and if/then/else functions but haven't been getting anywhere. This is what I have, very simple indeed:
i have in place an fade in application of addclass to a selector but i would like the transition to use one of the easing plugin equations instead for more dynamism. I can't tell how i would do this, since all the examples only use the animate function.
In pseudo code, here's what I'm trying to do with some text: shrinkText.changeText.EnlargeText. The jQuery I'm using for this: $('span#calendarNumber').animate({ color: '#999', fontSize: '12px' }, 500 ).html($('#calculatorSampleInPopup1').val()).animate({ color: '#900', fontSize: '40px' }, 2500, 'easeOutElastic' );
What happens visually upon triggering this is this: - HTML content changes - text shrinks - text enlarges I think what is happening is that the first animation is suppose to span 500 (miliseconds?) but jQuery doesn't pause for that, it just starts the animating and goes immediate to the second event which is to change the text. In otherwords, I think it's triggering correctly, it's just not producing the visual effect I want. Is the solution to put a pause of some sort between the first two events? If so, what's the proper method?
I have a group of 4 divs and I'm looking to use jQuery to animate them once, then have a delay using delay(), and then run another set of animations on them, putting the divs back to their original configuration. Here's the code that I have:
//only selectors called 'option1' are affected by delay, and not 'option1 img' or 'option2' $("#option1").showOption1().delay(3000).hideOption1(); //if i don't attach to #option1, delay doesn't work, but the animations that need to happen simultaneously work
[Code]....
will work from hideOption1() after the delay. The rest of hideOption1() is fired immediately after showOption1() finishes, ignoring the delay.
On the other hand, if I run line 5, all the code in hideOption1() runs simultaneously as desired, but ignores the delay entirely, running immediately after showOption1() finishes. How can I have all the code in hideOption1() run simultaneously after the delay?
So I have a navigation thats decently simple, but the JS doesnt seem to operate in the correct manner. When i hover over a child navigation list item, the parent will start its animation as well. I know when you hover over the child you are in turn hovering over the parent, but is there a way to get the parent to not animate? [URL]
I want create a page which has animation at the bottom of that page. I use jQuery to do that. This is the way I do it <a href="#" class="animation">Animate this</a> And this is the jquery
$(document).ready(function() { $('a.animation').click(function(e) { e.preventDefault(); //animation goes here; }); }); When I run the code, all animation run very well except the page always scroll to the top. I try to change the href attribute to javascript:void(0); but it still run like that..
I want to use the Ajaxify-Plugin ( URL... ) for my new Website. It fits exactly my needs.Sadly the animations are not working correctly.When your Internet-connection is too fast, you don't see animations at all (on a local machine also). I putted up a demo: URL...The content is supposed to fade out, then the new content gets loaded and then this new content should fade in nicely again, like in my own example, which I got from a tutorial that is just using pure jQuery resources: URL... [code]
The author of the plugin himself is using a server delay to overcome the sideeffect ( URL... - click some links under "New v2 features"), but i think that's the wrong way to go for production.Sadly im not good enough in JavaScript-programming to tweak the plugin by myself, to get it to work like in the second example... I tried it now for 6 hours.I would really like to use Ajaxify, because it has all the features I need united in it. The only thing that is not working are this animations.
I have some elements that hide and show real quick when I click on the same selected checkbox. I only want to hide or show something on change, and only when I need to. The way the behavior works now is I have 20 checkboxes, and each time I check one (even if it's the same), I see the associated elements hiding, then showing real quick. I don't want anything to happen though if all they do is toggle the checkbox, unless there's a condition to uncheck it. It's kind of hard to convey what I'm talking about here, but maybe my code can shed some light:[code]
I am making a single page website for a client and we are trying to make a 4 step animation on click of an image. When clicking the image I would like to slide out div1 up, slide out div2 right, slide out div3 down, and have div4 slide in.
I have several elements that I can perform show hide and fadeIn animations on but I want the action to continue on an endless loop. Is this possible? If it is, are there any cpu usage issues when using a loop? <script type="text/javascript"> $(document).ready(function(){ $(".upright").hide(300); $(".cntrlg").show(300); $(".cntrlg").hide(300); $(".cntrmed").show(500); $(".cntrmed").hide(300); $(".cntrlg, .lowleftmed").show(100); $(".cntrlg, .lowleftmed").hide(100); $(".lowrightmed").show(300); $(".lowrightmed").hide(300); $(".cntrmed").show(300); $(".cntrmed").hide(300); $(".upright").show(2000); $("#dai1").fadeIn(3000); $("#dai2").fadeIn(3000); $("#dai3").fadeIn(3000); $("#june1").fadeIn(3000); $("#june2").fadeIn(3000); $("#june3").fadeIn(3000); }); </script>
