Online Javascript Syntax Checker
Jul 2, 2002
I have a whole heap of Javascript that I want to compress (by removing line breaks etc). When laid out with line breaks, all works fine. When compressed ... BANG!
I suspect that there is a semi-colon missing somewhere which is only breaking when the return is removed. However, I'd like to run the whole block of javascript through an online validator instead of straining my eyes trying to locate the piece of the script at fault.
Is there such a thing? When I search for 'Javascript validator', I get a whole heap of links to using javascript to validate forms and such like!

I have come across javascript lint but it seems to be a bit outdated... is there a more up to date syntax checked for javascript or does javascript lint still do the job?
There are several online tools I have seen but unfortunately these are no use as I need to be able to run it from the command line and (hopefully) be able to import it into vim.

I am looking to use a spell checker in my multi-field forms and am trying to
find something open source and easy to install and use.
It could be either AJAX, DHTML or Javascript.

Trying to debug someone else's javascript code. There is a line that
looks like this:
req = req.substring(req.length-2, req.length);
From what I can gather in their comments, they want to capture the last two characters of the string "req".
I'm guessing that the above line won't do that, and they want to change it to
req = req.substring(req.length-1, 2);
In other words, the parameters are starting position, and length. Is that correct?

I discovered this syntax on the google example of a client to their web
service.
function PagClass()
{
this.init();
}
PagClass.prototype = {
init : function() {
this.m_bInited = true;
this.m_nTotalRows = 0;
this.m_nFirstRowNum = 0;
this.m_nRowsPerPage = 0;
this.m_nNumPages = 0;
this.m_nReportid = 0;
this.m_nResultNumStart = 0;
this.m_strStart = "";
},
foo: function() {...},
bar: function() {...}
}
This seems like a very elegant way to create classes in javascript,
gives you a constructor and lists methods as comma separated
properties.
My colleague is suspicious that there may be excessive runtime overhead
associated with the prototype, property list way of doing this.
Anybody know for sure?

Mixture of PHP & JavaScript as you can see.
Code:
/*--------------------------.
|Style Chooser |
|__________________________*/
$style = $_GET['style'];
$res = $_GET['res'];
IF ($style == "") { $style = "v2-green"; }
IF ($res != 1024)
{
print "
<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
function redirectPage() {
var url640 = "?res=640";
var url800 = "?res=800";
var url152 = "?res=1152";
var url1280 = "?res=1280";
var url1600 = "?res=1600";
var urlnorm = "pieeatersanonymous.com";
if ((screen.width == 640))
window.location.href= url640;
else if ((screen.width == 800))
window.location.href= url800;
else if ((screen.width == 1152))
window.location.href= url1152;
else if ((screen.width == 1280))
window.location.href= url1280;
else if ((screen.width == 1600))
window.location.href= urll600;
else document.write(urlnorm)
// End -->
</SCRIPT>";

I not much of JavaScript Developer, I'm a member of the copy and paste JavaScript Generation, so perhaps someone can tell me where I'm going wrong with my function to compare two dates:
var dt1=document.booking.fromDate
var dt2=document.booking.untilDate
if (Date.parse(dt1.value) >= Date.parse(dt2.value)){
alert("Departure Date must be After Arival Date")
return false
}
return true
The problem seems to be that two date values are been compared as strings, how can I force them to be compared as dates. I thought the Date.parse() function would handle that.

You're going to look at this code and see straight away what's wrong with it, but I've been staring at it for too long that my brain just isn't reading it right.
It's a basic input, you type in your postcode, if it is in the list of postcodes I entered then it replies with a 'Yes' response, otherwise a 'No' response. Unfortunately it keeps saying 'Yes' to anything that's entered.
Here it is, and apologies again for it being annoyingly simple, you know when you've been looking at code too much and you just can't see the small things anymore. [input type.needed=coffee]

I'm building a simple custom dropdown menu for a web-site so that I can control look and feel as well as the behavior of an iframe.I've set it up so that when the user clicks on any of the menu's active components, an "if" sequence in the clickHandler() function is activated that gets the element's class. If the event occurred on a dropdown option, the event-target id is checked, and the appropriate function is called. At least this is how it's supposed to work.All of the drop-down options have been assigned the "dmo" class. When I test the menu and click on other elements, it works fine. But when I click the "dmo" drop-down options, nothing happens. Firebug and IE Explorer Developer Tools both show no errors, but on clicking a dropdown option, the correlate code doesn't run at all, and after hours of head-banging, I have no idea why.

I have a js counter which keeps track of how many chars are in a field on an asp form. When the user clicks a button further down in the form, the form generates more fields. This also causes the js counter to reset to its original value, as the page is 'reloading' in a way. How can I check this value and keep it the same when the user clicks this button?
I am including the code I have.
javascript
counter in code
button
I have tried
It compiles but the value remains reset.

I'm new to Javascript but not new to programming.
I find JS more time consuming because I have to manually search line by line for a single error. In C++ or C the compiler tells me the exact line number of the error or at least what the error is so I can research it.
With JS, notepad or Firefox's source viewer doesn't indicate anything. Is there any software available that will error check JS codes?

I have the source code to an old BASIC program that a friend of mine
would like to run online. I am a beginner at JS, but I think that it
would be a good choice for the project. My background is in C/C++ and
web development.
Any suggestions that might get me off to a good start here? I can
provide more information if needed, but I am not sure what would be
helpful. The program is 550 lines in what appears to be BASIC and is a
calendar conversion program. You give it a date and it will convert it
into one of many other date reckoning systems (Gregorian, Hebrew,
Egyptian, etc, etc).

I am considering writing an online graphing utility. I plan it to be
of good quality, such that an undergraduate university student can
print it out and include it with a lab report.
Data points will be entered, having been generated by another program;
the utility will NOT accept functions for plotting--just the data
points.
As far as I know, Javascript does not provide graphing functionality.
Could somebody in this group please let me know what the best language
to use for writing this utility.

I am very new to web development. I would like my website to have an application which allows a user to draw images which can be displayed on other users screens in real time.
An example of this is isketch.net Also on this site i would like users to be able to create accounts and join 'rooms' where they can communicate in real time (as opposed a forum message board). I am looking for something similar to isketch.net
Could somebody please tell me the type of development and programming needed. I have been quoted 1000 a month to build these capabilities but have no idea what is involved. (also may require facebook style real-time updating)
