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?
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?
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?
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.
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
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?
What I want to do is to make an html page load a different background image every time it refreshes.I will have a list of background images and I want to be able to add in this list, without having to change anything else in the codes after I do this (I think this is made by making an array of images and by putting .length somewhere in the codes, but I don't know exactly how I should do this).I already know how to do an external file (.js) and link to it from my .html page.Now I want the code to put in the .js file, and the code to put in the <body> of my .html file.
I have an embedded video set in an iFrame (the page is called on.php). When someone clicks the stop video button, the iframe is re-directed to off.php, and the video is replaced with a play video button -- which when clicked takes them back to the video (on.php).
What I want to do is install a cookie that will permanently 'remember' which page the user has selected (on.php or off.php)... and then from that point forward will always load the appropriate page.
I've seen all sorts of tutorials about setting cookies and stuff, but nothing that would clue me in on how to accomplish what I'm trying to do specifically.
i use jQuery 1.3 and would like to make the following code run as soon as the elements i am targeting have loaded (or as soon as the page has finished loading). At the moment, I can only get it to fire on an event related to the target (in code below i'm using "hover"). Ihave put this snippet of code inside the document .ready handler, which is where I assume i should put it (?):
is parsing html to display in browser slower than doing it through dom to display the same html objects on the page?
