JQuery :: Script Not Supporting Massive Strings
Oct 27, 2011
I'm programming a function that breaks a massive string (2 million + characters) into "manageable" chunks of 500,000 characters. The function goes as follows [code]...
As you can see, everything should work fine, and the function should return a stringified json array (which would be parsed and sent to a server) but the loop stops after the first interval. When I decrease the length of "v" using substr to 5 characters, the loop works fine. What could the problem be?

I have been using jQuery for only a few weeks now, replacing all of my standard js in a massive Intranet PHP application with lovely and space-saving jQuery. However, I've been using FF to write and test code while the company standard is IE6. Nothing works in IE6 - nada, zip, zilch. It bugs out on the very first call to the js file and wants me to begin debugging. Am I correct in assuming that I'm going to have to go back to regular js? I'd love to get the company to upgrade to IE7 - I've not seen ANY complaints about IE7 and jQuery.

I have a following problem:
from time to time an attack on my page is performed,
overloading the server. The administrators had to limit the
access to the page to some domains only. I would like to
keep the page open for everybody.
Probably I should introduce a JavaScript/CGI driven form and
let user to copy some letters etd. before letting him
entering the page.
I am sure there are many solutions to this problem around,
but I don't know what to search for. Can you give me some
tips where to start?
I think the attacs are just casual, there are no real
reasons why should anybody try to copy or destroy the page
(no commerece, no money to loose or gain), so probably I
should start with something simple.

I have been struggling with a loop of mine. The loop should create a grid, of 204,000 squares(div's). And the total would create a grid field of 340 pixels by 600 pixels. All div's are sized 1 pixel.The idea is to create a grid, that shows temperature data in a gradient style, like a weather heat map. The data is collected from temperature sensors which are connected to a database.The only problem is that because it's such a massive amount of calculations to be calculated by javaScript, the whole thing freezes. Here is a sample of my code:
Code:
function makeGrid()
{
for (var i = 0; i < 8160; i++)
{
[code]....
Another problem is, the grid should be reloaded every 5 seconds or less.Because that's the interval used by the temp sensors, and for the usage that's planned for the project, its really important that the data is constantly up to date. using another web based language are welcome, as long as they are combinable with PHP or AJAX. Or maybe there is a ready to use library that I dont know of. Couldn't find anything for jQuery.

I went through the past six months or so of entries
in c.l.javascript, and found a couple where people
had expressed opinions about the value of supporting
much older versions of Netscape and IE. The entries
included incidental mention of server logs showing
how many pages had been retrieved by such browsers.
I'd like to get some sort of communal variety of
opinions on how much effort it's worth to put in the
support, or in some cases, the "graceful degradation"
allowing partial capabilities to remain in a page
under the old browser.
My situation is that I have no access to server side
capabilities or CGI, have yet to buckle down and learn
Java, but have a fairly complex application I'd like
accessible via the web.
Are there links answering:
1. How many commercial sites still insist on full
compatibility? Allow significant degradation? Give
up on NN < 6? Ignore browsers with small market
shares?
2. How do developers feel about coding for browsers
older than, say, two years?
3. Are there statistics from a variety of sites
showing use by different browsers?

I want the list of browser which is not supporting Java Script.
So far I am thinking only JavaScript is the standard scripting language
supports in most the browser. Is any scripting language supports in all
browsers.

I just tested all the browsers I have for support of
document.documentElement.scrollLeft to determine how many pixels the
window has been scrolled to the right. I'm trying to determine if I
really need to go to all the trouble of feature detection for determine
page scroll amount of if the old browsers are old enough now just to
ignore them.
Below are the OS-browser combinations that worked in my test.
OS X 10.4
Safari 2.0.4
Opera 9.00
Firefox 1.5.0.6
OS X 10.3
Safari 1.3.2
Opera 9.00
Firefox 1.5.0.6
(Failed in Internet Explorer 5.2)
Windows XP
Internet Explorer 6.0.2600.000.xpclient.010817-1148
Firefox 1.5.0.6
Opera 9.01
IE 6 was released in August 2001 which is a long time ago so worrying
about IE 5 seems unnecessary for some kinds of web sites. And IE 5 on
OS X is a tiny fraction of people surfing the web.
Does anyone know which are the most recent browsers that would not
support document.documentElement.scrollLeft? Any mobile devices or are
they all running something based on Mozilla or Opera?

I've been learning javascript for about a week and I'm really struggling right now. This is a homework assignment to help in learning loops and arrays.
What I want to happen is when a form button is hit it will replace the array from the one previous instead of just adding to it. Hopefully that makes sense. What do I need to do? here's my code....

What I want to do specifically is add a CSS class to strings that start with an @ symbol. I can't seem to find any examples online and I haven't had enough experience with jquery to figure this out on my own.
I want it to highlight either the first word only, or just the line that the @ symbol is found on.

The follow jQuery code doesn't work. Does that mean jQuery doesn't support such a usage?
Code JavaScript:
var selectors = ['#header', '#content', '#footer'];
$(selectors.join(',')).addClass("new");

Is there a simple way to just hide some text in a page? Browsing the documentation I found the .hide() function. But how can I tell jQuery to hide all occurrences of a specific string? If I use the :contains() Selector I can find the text but can only hide the element that contains the text not just the text.

I want to create a questions creation page. It has a Question Text Box and a Add Button.When users press the add button, there will be a newQuestion Text Box and a new Add Button appear in the next line. But the old Add Button will become a Delete Button and change its functionality.[code]I put all the Add Buttons and Minus Buttons into two different classes, ".buttonPlus" and ".buttonMinus".The .buttonPlus works well when the line is added by the main html. But it fails to work when it is added by the .append() function. It simply adds the .buttonPlus's CSS code to its button, but the$(".buttonPlus").click(function (event) {...} is NOT attached to the new buttonPlus.

The scenario would be something like checking if an element fulfills some complex conditions, something like if(myElement.is('div.someClass[someAttribute], td.someOtherClass[someAttribute]')) ... . Is there a way to parse that string only once, maybe create some sort of "compiled" version of the check, cache it, then give it to is ? Or does jQuery cache the string after parsing it once so I don't have to do anything?

I've been using jquery for some time, and was very excited about the improvements in jquery 1.4 I have found however, that in one particular instance, jquery 1.4 seems to be performing slower than 1.3x, to the point that it has forced me to downgrade the script. I use jquery heavily throughout my web application; in this particular case, when a very large block of html consisting of a bunch of <tr>s is .appended (or .htmled, tried both) to a table, jquery 1.4 in firefox will give the "unresponsive script" error, prompting the user to stop, debug, or continue. The same block of html works perfectly fine in jquery 1.32 (and quite fast too). I haven't had time to do too much experimentation, as this is in a production environment, and thus downgrading was necessary as it was breaking the page, but I would love to figure out why this is happening so that I may optimize the code sometime in the near future. Have the improvements to .html resulted in code that causes higher cpu usage, or that would have a much higher overhead on longer strings? I've commented much of the code around the call, so that it pretty much consists of an ajax call that returns a chunk of html, which is inserted to a table (that I first empty). I thought it might be something with event bindings that occur after the insertion, but removal of these event bindings does not resolve the unresponsive script error. It seems the .html or .append is doing it. Note that this code, as is, works perfectly in jquery 1.3, even with event bindings, etc.
Does anyone have any ideas? My next step was going to be to try returning the entire table including the <table> tags, and doing a replace instead of an append, but if anyone has other suggestions to try, please let me know. Also, just as an aside, what do you guys consider the 'best practice' to be when returning dynamic data for a table (server side sorting, filtering etc from a db) ? Do you return just the data in json, and repeatedly clone a row element, replacing the values in each row (thus decreasing the size of the ajax call, but increasing the client side processing), or return the full html, and replace the innerHTML of the table?

I have a set of tabs that are set with an href that adds a query string to the url such as "?t=1", meaning the first tab is selected.
Technically it works just fine but every time I click a tab it reloads the page and I'm not entirely sure how to stop this.
I'm using a jquery plugin to handle the query strings. [URL]
Here's the piece of the code that matters:
var url = location.search;
var tab = $.query.get('t');
init(tab);

Demonstration code:
The 'array' variable contains strings representing the id's of different elements. If the for loop above were to finish iterating, would all the links in all three elements call the click function (that displays an alert message), or would only the last element ("element3") have the click function? For me, the latter seems to be the case unless if I'm doing something wrong, but I would like clarifications and, if possible, alternative solutions as to how I can achieve the former result.

I'm having difficulties arithmetically manipulating form element values.
I've entered data into the form, and I fetch them using a js, as:
p7Left = Number(document.form1.elements["p7_left"].value);
p7Right = Number(document.form1.elements["p7_right"].value);
...
...
scoreLeft = Number(document.form1.elements["left_score"].value);
scoreRight = Number(document.form1.elements["right_score"].value);
Then I add these as follows:
scoreLeft = Number(scoreLeft + p&Left + ...... +);
This does what I want; without the operator 'Number' I get a concatination
of the various variables (as expected). Is there some way of globally
defining all variables as numbers instead of strings?

Safari and FF seem to allow this:
var wiggy = "ABCD";
ch = wiggy[2]; // ch will contain the character 'C'
however my JS book seems to insist that I do this:
ch = wiggy.charAt(2);
and indeed doesn't appear to mention the first method at all.
Since for my particular purpose I want to treat the string as an array
of single characters, I prefer the first method rather than the second.
Is there any reason not to pursue this approach?

I have two strings that I need to compare and modify when there is a
matching value in the two. If strA = ??,' then I need to remove
the value ??,' from strB and the new value would be strB =
??,12935'
strA = ??,'
strB = ??,12937,12935' (these could be any values in any order)
I'm not sure where to begin on this.
