FF, Safari and Chrome run it fast too. I don't understand how my site can be slower on IE8 than on IE7 O_o
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?
How do I make my Script load faster?
Is there Code that will make my Script load faster,
(so that it won't take so long to view)
If so, can someone show me how to incorporate it into my Example Script

I want to create a popup window that opens when the index.htm page
loads..
Within the popup window, I want to create a link to 'more info'.
When this link is clicked, I want the content to load in the main
window, not the popup, and I'd like the popup to close !
I have used a Javascript to prepopulate text fields and checkbox's etc. However I can't make it populate a text area.

Set the title of your page, to what you want to be seen in the email.
The document title is used for the email title, and the subThanks window
title.

// Focus the first form element
function focusIt() {
window.document.forms[0].elements[0].focus();
}
// Redirect the user to a thank you page
function redirectIt() {
window.document.location.replace("thanks.htm"); // ## Change the page name and or location to your thank you page. ##
}

##
The subThanks page displays information to the sender about what has been sent.
This page also gives them a chance to print a hard copy for there records.
If you wish to change any of the format of this window, becareful, table information is
set in three areas. The first area is in the Variables below, col, cot, coz and brk.
The second area is in the newWin.document.write lines. this area is the top portion of the new
window. It displays a thank you, displays ths user email, the form name, last name and first name,
as well as the top print button. The third and final area, is what is used to generate the rest
of the table. You should not have to touch any of this, as all the cell formatting is done in the
top Variables.
If you change the name value of your First Name, Last Name and Email address, make sure to update
this information here in section two as well. reqRequestor_First_Name, reqRequestor_Last_Name
reqRequestor_Email are all called in the second section.

The below section is the third section for generating the subThanks window.
This section loops over the entire form, and then writes the information to
the new subThanks window. There are some rules to what is shown and what is
not shown in the subThanks window. Everything else is printed to the new window
accept the following.
1. Checkboxes and Radio buttons that are not checked
2. Button Types
3. Hidden fields
4. hidden form objects whos name ='s "=================================================="
This is used for a break, when the loop finds an element with the above equal signs, the
Variable brk is written which is equal to "<tr><td colspan=2 bgcolor=#e6e6e6> </td></tr>";
This break is definded above at line 89
5. The Table is closed when the loop hits a submit or reset button.

I'm looking to create a multiple selection drop down menu that has radio buttons & text. For example
[MENU] <-click
[MENU] <-after click
--------------------
| (x) Selection one |
| (o) Selection two |
| (x) Selection three |
| (o) Selection four |
--------------------
so basically, like a <select> except it has radio selections and you can pick several choices. When you select one, that whole row is highlighted (background color of that row changes). Would I use javascript/dhtml for this? I'm guessing so.
I want to use this code but there is no step by step instructions.

i'm new to jQuery and SVG and my homerwork is to develope ECG chart. It should show data with: - 25mm/s - 50 mm/s - 1mm/mV - 5mm/mv I've decided to use Keith Wood jQuery plugin and have some questions. Is it possible to manipulate with gridlines when using graphing extension? I'd like every full second line to be thicker than the rest. Secondly, length on chart in every resolution should be equal to real length. Or should I make that chart step by step using drawing functions?
View 2 Replies View RelatedI'm trying to develop proper exception handling for a javascript framework I'm developing but I keep hitting an annoying dead end: caller and line numbers / stack trace.I have a basic exception class:
Code:
/**
* Exception.js
*
* @classException
[code].....
The problem is that the console.trace() function returns only one line: "log", referring to ExceptionHandler.log(e) (at least in webkit). What I'd love to do is have the Exception class get information as to (at the very least) what called it and also, although perhaps less viable, the line number it was called on. I don't think the line number is going to work though. I would _like_ this to happen automatically, but if I have to include another argument called_from it won't be the end of the world. I know about arguments.caller but this is depreciated (as of ECMAScript 1.3 (?)).

View 4 Replies View RelatedI'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?
View 6 Replies View RelatedAnyone 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 add a search feature into a literature review i'm converting to HTML for work. This is to be burnt to a cd and given to a client. At present I can only do a simple keyword search through the entire collection text (i'm NO programmer i'm afraid ), I need to add boolean features to this so that ppl can search for "word1 AND word2" sort of thing. Can anyone give me some pointers as to how I might accomplish this?

The document object has a method called createElement. Can I use this
method to create a new Drop/down list, like:
var sel = document.createElement('SELECT');
I have seen it used like this:
opt = document.createElement('OPTION');
which means that opt now holds an option that can be appended to an already
existing select object.
Are there any restrictions for which arguments createElement can be called
with? I have seen: var what is "LI"? Where do I need to look to find valid arguments for createElement??
