Upto Date Syntax Checker ?

Nov 12, 2010

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.

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!

Date Checker?

Feb 27, 2006

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.

Simple PostCode Checker - Can't See For Looking

Feb 9, 2009

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]

Custom Menu CSS Class-Checker Script Not Running

Nov 15, 2009

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.

Count Checker - Track Of How Many Chars Are In A Field On An Asp Form

May 19, 2010

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.

Compiler/Checker - Notepad Or Firefox's Source Viewer Doesn't Indicate Anything

Mar 19, 2008

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?

IE :: Date Loading On A Booking Form - Date Does Not Load On Internet Explorer?

Feb 14, 2011

I have added a booking form to a website with belongs to fastbooking.You can see a temporary website here. http:[url]....It works perfectly fine in Mozilla Firefox, Google Chrome, Opera and Safari but it does not load on Internet Explorer.On the other browsers the form loads todays date and the year is generated but on IE the date stays on 01-01 and no year is generated.I'm using wordpress as a cms.I think the code that is not loading is <body onLoad='start();'>But I'm not sure. The code of the year is

<select name='fromyear' class="input" onChange='update_departure();'>
<option value="0"></option>
</select> But since it's no just the year I assume its the onload code.

I tried to add the onload to the header function like this

<body onLoad='start();' <?php if(function_exists('body_class')) body_class(); ?>>

So now wordpress generates the following code when it loads the page

<body onLoad='start();' class="home page page-id-6 page-template page-template-default logged-in">

But sadly the date still does no load on Internet Explorer.
