Jul 20, 2005I must admit that the more I use and learn JavaScript, the more
convinced I am that it is one of the most expressive languages I know.
Without ways to access file i/o or databases though, can JavaScript be
considered as a serious general purpose language?

Nov 28, 2009I have firebug installed in my firefox browser, but I can't get console.log, console.debug or console.trace to work. My console window remains empty despite all my efforts. For example I have some code which throws up an alert box ( alert ('here is an alert') so I know 100% that it is being executed. If I now place the line
console.log("please log this to the console");next to it, nothing gets written to the console. I also have firephp installed and this is logging to the console for my php code absolutely fine

Nodejs - Use Console And Other Basics ?
Jan 4, 2012I'm just getting started with nodejs. For now my purpose with this tech is to finish a book (The Definitive Guide to HTML5) where it's covering ajax and is using node.js to send the code back. I do want to learn the basics while I'm at it.
What I have so far: I understand that node.js lets me write my own web server. I understand that nodejs is actually 'C' and it just allows for us to write JS to make a web server and do other back-end tasks.
I've installed node.js on my windows 7 64 bit machine. I have found out that I can run a script on a node by right clicking it and selecting open with "Evented I/O for V8 Javascript".
What I want to know is how do I run node from the command line? What are the boundaries of the JS file that I write? From what I can tell, I can goo all over the place with my js file traversing my filesystem as I please. If this is true, how is it safe? It seems like it would be easy to hijack some simple js file and go all over the servers file system at will for a hacker....If someone could fill in these holes.

Errors Found In Js Console (firefox)
Mar 16, 2007I'm using firefox javascript console to find errors within my webpages.
I've found the following errors:
"Expected colour but found '#'. Error in parsing value from property 'color'. Decleration dropped. Line 0"
" Error in parsing value from property 'display'. Decleration dropped. Line 0"
How can i go about finding which lines of code are creating these errors? as it tells me its on line0, this gives me no clue as to where to look.
Ie Js Console Doesn't Show Correct File
Sep 30, 2006everytime i test my websites in ie (which should be done seperately
from ff) the console shows me the error and the line number.
problem: it shows me the line number of the file of the error's origin,
but it shows me the main html file as file name.
i am developing a bigger project with many js files and often i have to
go through all js files cause i don't know really which file is meant.
String.replace In Console Verses Web Page
May 17, 2007I find myself having to dynamically create HTML code, and have found
that the usual way you see to do this is an unreadable mess, like this:
blah('<span id="' + id + '"><a href="' + link + '">' + linkText +
'</a></span>');
So instead, I would like to do something more like the variable
interpolation in Perl and other languages:
blah(XXX('<span id="@id"><a href="@link">@linkText</a></span>'));
The XXX function here would interpolate the values of any variables
named with a @ prefix into the string. Why @? Why not?
So using my favorite JavaScript console (FireBug), I typed the following
and ran it:
x = "hello world";
y = 42;
z = "--@x/@y--"
z = z.replace(/@(w+)/g, function (dummy, v) {
return eval(v);
});
alert(z);
And it works. The alert box shows "--hello world/42--" as expected.
Okay, so now let's turn it into a function:
x = "hello world";
y = 42;
function XXX(s) {
return s.replace(/@(w+)/g, function (dummy, v) {
return eval(v);
});
}
alert(XXX("!!!@x~~~@y!!!"));
And again, it works. The alert box shows "!!!hello world~~~42!!!" as
expected. I should be able now to just drop this *same* code into a
<scriptsection of a web page, right?
Wrong. If I take the *same* code as my second example and plop it in a
web page, the alert does not show the same thing as when in FireBug's
console. It shows the same string passed to XXX, unchanged.
Other experimentation tells me that when placed in a web page, the
anonymous function to do the eval call is never invoked, which suggests
that the regular expression didn't match.
I've only tried this in FireFox 2 and IE 7, but if it doesn't work
properly in either of those, I really don't care about the other browsers.
My guess is there is a difference in the execution environment of
FireBug's console (or likely, any JavaScript console) and the execution
environment of a web page. The questions are what is that difference,
and how do I make my XXX function work properly?
JQuery :: Append() Works From Console, Not In Code?

Console :: Log Cancels Loop When Firebug Disabled?
Nov 30, 2009Is this a bug or a feature? In this code:
Code:
for (var ur=longestRow; ur>1; ur-- ) // adjust rows above it
{ console.log("going to call spaceRowAbove("+ur+")");
spaceRowAbove(ur);
}
If Firebug is enabled the message is logged and the function is executed.If Firebug is NOT enabled, the function is not executed.If the log statement is commented out, the function IS executed.Wouldn't it be more reasonable for the interpreter to ignore just the console call, rather than the whole loop?Or is it just me and my Firefox 3.5.5?
Writing To Firefox/Mozilla Javascript Console
Apr 13, 2005Firefox has a Javascript Console that has 3 panels besides "All" and "Clear": "Errors", "Warnings", "Message".
Does anyone know a way to log a message in the Message panel with JavaScript? That would really help debugging. I know there's a way involving XPCOM, but that only works with "trusted" scripts, and scripts loaded thru html aren't trusted.

View 5 Replies View RelatedDual Purpose Rollover (rollover Image And Iframe Change)?
May 11, 2010Before, I had an iframe, and when I moused over a link outside the iframe, it would load a page into the iframe. Background image was part of the page loaded, as well as the text and what not. The problem was, the image took too long to load. I've been learning how to do javascript and I came across some code for preloading an image before the mouseover so there was zero wait time. For the past few days I've been trying to figure out how to have the preload image appear BENEATH the iframe (now with no background image or color) with the allowtransparency attribute set to true.
I've figured out the code to do both individually, i.e. I have the code so that when the link is moused over, the new image will appear; AND I have the code so that when the link is moused over, the page with load into the iframe. Both work, both do what is expected, but they don't do it together.Below is the script. Here's where it's confusing. If I have the "setupImgRollover..." first inside the if statement: the page loads into the iframe, but there is no image. If I have the "setupImgRollover..." after the "document.link..." commands in the if statement: the image appears but the page does not load into the iframe.
HTML Code:
window.onload = rolloverInit;
function rolloverInit() {
for (var i=0; i<document.links.length; i++) {
var linkObj = document.links[i];

JQuery :: Document Ready Function Not Defined In Console
Jul 17, 2010I am getting $document.ready(function() not defined in the firebug console. I have seen that in most cases this is caused when the jQuery core is missing or the path is invalid. I do not believe this is the problem in my case becuase firebug shows the code as being loaded successfully and it is readable.
I have the following scripts in my head;
<script type="text/javascript" src="jquery-1.4.2.min.js"></script>
<script type="text/javascript" src="jquery.validate.js"></script>
<script type="text/javascript">
jQuery.validator.addMethod(

Ajax :: Firefox - Not Sending POST Data - Nothing Shows In The Errors Console

Child(iframe) / Parent Form - Administration Console To Upload Images With PHP
Jul 14, 2010I am working on a form inside my administration console to upload images with PHP. In my form I have the following:
[Code]...
The onchange submits the form to a seperate PHP file (sent in the action of the form) dedicated to handling the uploading of the images, while the submit button(not shown in code) will submit the rest of the form through ajax. In order to use 1 file field, Ive read that to get an ajax looking effect I need to use an iframe, so I added the IFrame into the HTML and got the effect working right (without actually uploading the files.)
Now I want to limit the ammount of images to 8. Which is where the hidden field came in. So i've got to figure out a way to count the successful uploads, or add them as we go. At which time that number turns to 8, the script will disable the file field from anymore uploads. Problem is I have no clue where I need to go within my php file to make this happen. Here is my php file with javascript added in:
Code:
<?php
// lets go ahead and get this image uploaded
?>
<script language="JavaScript" type="text/javascript">
var parDoc = window.parent.document;
var upldcnt = parDoc.getElementByID('upload_cnt').value;
[Code]....
