I'm writing a blog post that uses multiple videos from YouTube and Yahoo Video, but I'm not happy with how long it takes the page to render. Apart from using an ajax-y method to load the videos, are there any tricks that would make the page load quicker with multiple videos from different sources?
works ok, but my alert box comes in really slowly, then bounces. I want it to appear faster and to also appear after exactly one hour. I don't think that works right either. What do I need to change in order to do this?
I have a ajax program on a page on website A. And I need to let it talk to a program on website B. I tried to put website B into the url of the parameter but it doesn't work.It gives me a "[objet XMLHttpRequest]" error.here is the code on website A:
I'm trying to select client side language to learn. For some time i wanted to learn Javascript, but when i tried writing first script which was so simple, i saw that it has so much problems. I thought of flash, and read few tutorials online. It's pretty simple but powerful language.
I know that probably worst feature of flash is that it's not included by default in your browser, but since youtube and other video sharing services i think that flash players on browsers are drastically more installed then before, and that almost everybody has it.
Now, i'm planning to create chat for my personal website, and i saw Ajax chats, and Flash chats. Since i don't have experience with any of the scripts i'm wondering which code is faster Properly written Javascript, or Actionscript.
Also, which of these languages are better for me to learn. I'm learning web programming as hobby so don't use money as argument. But which of those two can be used for creating fun, dynamic, fast and safe programs easily
I've developed a calendar program in javascript, and up until now I've done most of my testing using Mozilla and Firefox. Everything works fine, but when I try to use Internet Explorer my response time is sometimes 50 times slower than using Mozilla.
I know I haven't given you much to go by, but I'm not looking for an answer so much as an approach to debugging the problem. For example, does anyone here know of a good web site which deals with browser-specific javascript performance issues?
I am currently doing a photography site.I would like to do a 'portfolio' page, but would like to pre-load the images so that they appear on-screen faster.Do I need to connect code to <body onload>?
Is it faster/more beneficial to have two snippets of code be generated by php at 2 different urls and then have a load function for each url? Or have the two snippets on one page, surrounded by id's and then load them that way?
Anyone loading a bunch of CSS or Javascript via <link> tags on a web page knows about "blocking": where the browser stops the loading of the page because it has to go fetch (and read/parse) an external file. If you have a lot of these, or even if you don't and the user has a slow connection, you have a slow page. Users hateses teh slow pages, hatses them.
At the 2010 Fronteers Conference, Stoyan Stefanov gave a talk on Progressive Downloads and Rendering, where he listed some tricks to get around blocking by Javascript or other external files to make page load speed up. One trick was adding a <script> tag in the body (near the bottom, so after the important stuff has loaded) which adds a <script> tag to the <head> dynamically and runs it. While that file is being fetched, the rest of the page can continue to load. This is a bit asynchronous, isn't it (similar to web pages still loading content while also fetching images)?
As a follow-up to his Higher Order Javascript article (see SitePoint thread about it), Piers Cawley has gone further with Asynchronous Streams, where he uses jQuery (as an example) to load external files asynchronously to avoid blocking of the HTML document loading. In my web development career I haven't worried about blocking, but plenty of folks around here are loading ginormous files, and lots of them, for large sites. As developers, what do you do to get around slow page loads? Have you done anything like this asynchronous calling of the external files?
I'm trying to code a feature for my website using DHTML where the person viewing the website can rotate between viewing the positive/negative points of the website being reviewed. This example was in the publication called Using HTML 4 by Lee Anne Phillips. Code:
Im wondering if generating html objects such as tabels and rows in javascript is faster than typing the html directly? Seems when you do it in javascript you have to download alot of code and would slow down displaying the page. while if you just type the html, it requires less bandwidth and display faster?
is parsing html to display in browser slower than doing it through dom to display the same html objects on the page?
I have a single webpage that contains information on all 50 U.S. states. There are 50 links at the top to jump down to the state you want, and at the bottom of the information for each state a Back to Top link.
I'm making the Back to Top link into something more complex, and it will require three or four lines of code.
So that I don't have to repeat the code 50 times, and create a burden when I need to edit it, I want to place it in a .js file and call it x. Then below the information for each state I'll simply have:
Does calling code from a .js file 50 times slow down the page load? Which method would load faster?
If you go to google and you search for a thing, you see a list of websites. On the right you can see a double arrow. I you placed your cursor on it, you can see a thumb of the website on the right.
I want to use a jQuery Lightbox for our new Web Site. I would like to have one lightbox where there is a large text sidebar on the right side describing the project represented by the slideshow. I would also like to style the text in the text box with Web Fonts if possible
I have certain features that use Jquery implemented in my website. I guess my hosting service does not offer support for jquery so I get these error messages when running the site.
Message: 'nodeName' is null or not an object
What do i need to do to make this work with my website?
