Get Local Specs And If High
Nov 22, 2011
I am a back en developer and really don't understand event driven/front end development so if I use newbie terms or make no sense please bare with me. Could someone point me to some tutorials on how I might render something if and only the local machine has good processing power/ram. I am going to be rendering some stuff which will require quite a lot of processing power on the local side. Just a threshold thing really nothing predictive or anything just if ram is more than 1GB and processor faster than a P4 or something like that.

I've been reading through w3c recommendations for DOM Level 2, e.g. Core, Html, Views, Styles, etc.
I can understand what the interfaces define, but it is sometimes unclear or hard to find exactly how these are mapped onto objects. There is the language binding section, but it doesn't define what interfaces the document object, for example, makes available.
Is there some agreed upon mapping, showing exactly which interfaces each object (should) implement? Or perhaps a website that attempts to show interfaces for each object.

I have a team website that has several games for entertainment. One
of the games is a javascript version of yahtzee. Can someone suggest
a way, using javascript, to record a high score for the game instead
of a high score for a particular user, session, or computer. Perhaps
someone already has code written to do this.

We are currently trying to locate the JS that will allow us to implement a progression of low-res-->hi res load for the big background images we have on each page of our new web site.In other words, we have a ginormous photo in the background, and want to avail the browser a very lo res version of said photo while the big photo loads.I have a feeling this is a real rookie question, but still, if there is anyone that can advise I'd be super grateful

I am fairly new to javascript but I am an experienced php programmer. I have been parsing XML information using php, but my CPU usage has been too high recently due to this. I am trying to convert my scripts to javascript, but I am unsure how I can do this using javascript. I think that if I get started off, the rest will be easy.
One of my XML files is located at
Code:
http://ws.audioscrobbler.com/2.0/?method=user.getrecenttracks&user=bbcradio1&api_key=c910b0bc1e2d4e64964ebcd2d69c255c&limit=500
Basically I have been trying to grab the Name, Artist and large image of the most recent <track>.

I am implementing a fairly large Javascript file that has many if/than's that decide whether to load new content into div's. I have noticed this is causing high client side CPU utilization. Is there any better way to do this besides having the example script below repeated many times... i need to keep CPU usage down.
Code:
<script>
$(document).ready(function()
{
//ajaxTime.php is called every second to get time from server
[Code]....

The jQuery library is definitely very useful for those who have development background experiences but don't have the time to learn Javascript in it's true nature. I've played with it on and off, on a few smaller sites I manage, and the outcome was truly amazing. I don't know Javascript at all, aside from the basics and I was able to create a very fun and fast UI very quickly for my visitors. I wonder though; Does the jQuery library hold up efficiency for larger sites?
I currently manage a site with over 1.6 million post, averaging around 15,000 post per day this month. With me not having the time to really learn Javascript and I don't have much of a budget to hire someone to do the work I want yet, it would seem logical to use jQuery if I already know how to use it, right? I just worry, with the growth rate for the site at it's all time high, I'm afraid that jQuery will do more bad then good.
Are there any high traffic sites successfully using jQuery that you know about? has anyone experimented with jQuery on their high traffic sites? Would it seems more sensible to hire someone to do the Javascript work?

I'm working on an interactive website where the user can change the font attributes of the text within the page they're reading. Is there a way to bind, for example, bold tags around a snippet of text the user has high-lighted? What I mean (if that wasn't clear) is if the user is reading through the text on the page and drags their mouse over a piece of text then clicks a button and it turns bold, much like a rich text editor would work, is this possible to do?

Is there a way to get the visitors *local* IP-address in javascript? I mean his LAN address like 192.168.1.x, not his regular IP-address.
I found several approaches that attempt to do this, but they either give me the external (regular) IP address, or they give 127.0.0.1 which doesn't really tell me anything. I need the local network address.
Just an alert saying "your machine's local network IP is 10.0.0.139" .

In jslint's doc it says, "JSLint does not expect that a var will be defined in a block. This is because JavaScript blocks do not have block scope. This can have unexpected consequences. Define all variables at the top of the function." What are some of those unexpected consequences?

Both an EtherNet (wire) network and a wireless network are referred to
as a Local Area Network (LAN). A wireless network does not require
hubs, switchers, or routers to include additional users on the
network. Additional wireless users are supported just by being in the
immediate physical span of the network.
A wireless LAN (or Wi-Fi network) may be configured in two different
ways:
Ad Hoc mode: Allows only for communication between different personal
computers and wireless devices, often referred to as peer-to-peer
communication.
Infrastructure mode: Required for communication with the World Wide
Web, a printer, or a wired device of any sort. In either case, this
wireless connection requires a wireless network adaptor, often called
a WLAN card. Code:

I am developing a web application where each page shows a series of small jpg images each with an onClick event which plays a small mp3 file using javascript.
It all works perfectly but is a bit slow to load, so the customer wondered if we might develop a local version which, although the page was accessed via the web, the images and mp3s were installed on a users local pc (will be machine specific application anyway).
I have managed to do this for the images by using:
<img src="file:///C|/folder/home.jpg" onClick="EvalSound('shortname')">
and adding the site as a trusted site in IE7 (after much head scratching!).
However, my embed statement to embed the local mp3 files doesn't seem to work. I am using:
<embed src="file:///C|/folder/filename.mp3" autostart=false width=0 height=0 name="shortname" enablejavascript="true">
I have tried all sorts of versions of this path and nothing seems to work. I just get an 'unspecified error' when I click the image.

My current set up is a form that gets someone to enter "City, State" then when they hit the submit button i used PHP to set up a variable called $location which was set to google.com/maps?q=from%3A+city,+state+to%3A+city,+state the $to variable is sent from a hidden input and is equal to the club they want to go to. After that i do a few string changes to get rid of the spaces. after its' all done it becomes $location.
What i currently have is a simple window.open() using javascript to open up the window. This works fine with one major problem.. popup blockers stop it from opening and the people browsing this site aren't exactly tech savy. They usually have no idea how to allow popups and this becomes a problem. The only reason i have it set up the way i do now is because my javascript is very limited.. but my php is pretty good. Is there a better way to open up the new window without popup blockers stopping it? If not do you know a way I could set up javascript to change a hidden input on the fly as the person enters their info so i can just use method="GET" and have the action to google.com/maps.

I've spent 30 minutes or so googling to find the answer to this question, and I haven't found it. I'd like to use JavaScript to get the contents of a URL on the same domain (locally). For that matter it will be within the same directory on the domain.I was hoping there'd be a simple "getURL" function that would assign the contents of a URL request to a variable. One that isn't terribly platform specific, either. Is there such a thing?I'm creating a script that will perform 3 different searches at my website, and place the results in 3 columns for easy comparison. It's somewhat of a metasearch, extracting similar items from 3 different websites. The local CGI script on my website (the one I'm hoping to call using Javascript) makes the query to the external websites. The problem is that it can take sometimes 5 to 10 seconds to finish all of this, where one site in particular can be fairly slow.
So rather than make the visitor wait 5 to 10 seconds to see anything at all, I thought a good solution would be to have the CGI script display a page quickly, showing that site #1 is being searched (and displaying results once it's finished), then site #2, then site #3. Ideally the results from site #1 would have JS that would trigger the search for site #2, and so on.I've done this before using frames, but I was hoping to avoid having to use frames.I'm not a JS expert, but I know how to use createTextNode to insert the contents of variable within the document.The only thing I need to know how to do is assign the contents of a URL request to a variable.

I am trying to make my site so that when my boss needs to view the website when there is no internet he is still able to go from page to page. I set it up in dreamweaver and just put not ftp information in it, does that mean he can view it without internet now. Also I can see my navigation which is a javascript navigation, when i view it in the browers.

I have Win 7, IE9. I have a HTML file on my hard drive, with Javascript within. When I load the page, it keeps popping up Do u want to allow this content, I have to click to allow. I want to stop this, and after doing some searching I found the setting in Internet Options, Advanced - "Allow active content to run in files on my computer".
Perfect.
Doesnt work. When i check this box, the page loads without the warning, but then the Javascript just doesnt work. Getting quite annoying, because this file is my home page.

I know I'm missing something about GMT stuff, the problem is that I don't know what exactly If I follow this steps I wont get the real time (for my country) but 2 h 5 m later. Where is the mistake? You can try the code under this lines:
Code:
var Cdate = new Date();
var Smiltotal = Date.UTC(Cdate.getFullYear(), Cdate.getMonth(), Cdate.getDate(), Cdate.getHours(), Cdate.getMinutes(), Cdate.getMilliseconds());
var Pdate = new Date(Smiltotal);
var Smonth = Pdate.getMonth()+1;

I'm looking for a way to define a function that's only effective inside
specified function.
Featurewise, here's what I want to do:
bar_plugin_func = function() { ...; setTimeout(...); ... };
wrap_func(bar_plugin_func);
bar_plugin_func(); // calls custom "setTimeout"
So while plugin developer thinks s/he's calling top-level function,
I want to hook it by somehow injecting local variable with the same
name.
Simply doing something like
;(function() { setTimeout = function() { ...my custom implementation
})();
is not ideal, as that'll taint global scope. Actually, I can live with
that for now,
but it's my technical interest to find a way to define it locally.
