Is there any such thing as a jQuery Debugger, i'm trying to learn jQuery but even small things like Syntax errors keep getting in the way and it's hard to track down without any error reporting.

View 1 Replies View RelatedI have a user name, password, phone number etc., that all need to be validated before being submitted. The functions filter out the unwanted characters and null and zero length strings. I did have a pop up that listed the errors but I would prefer them to be listed below the log in screen that is a hidden div.I cannot get it to work.The validation works fine,
<html>
<head>

Is there a way of telling the validation plug-in to use it's defaulterror messages when the title on the control is set? The defaultvalidation error messages are good for most of my cases so I'd rathernot have to explicitly set the messages for each and every one ofthem.For example, if I attach a "required" validation rule to a textbox andset its title to something, I don't want that title to appear as theerror message when they leave the field blank and I'd rather not haveto explicitly set the validation message

I'd be curious what the different approaches are to this. I looked through my various SitePoint javascript books and surprisingly didn't find an answer to this scenario specifically.The behavior I'm trying to achieve (most efficiently) is having a form start out with the submit button enabled, but if there is a validation error, such as a required field being left blank on blur, the submit button is disabled. It's easy then to re-enable it when the user fills in that field, but harder to get the script to check and see if there are any other lingering errors before going ahead and enabling it.
My natural inclination would be to just keep a count of errors that increments and decrements when errors occur and are resolved. Then the script would check to see that the error count is 0 before re-enabling the submit button. It seemed easy, but I think I'm getting mixed up somewhere in conflicts of variable scope, and it's not turning out right.A google search rendered an example where someone was using a string variable to store errors, concatenating and replacing data to the string as errors were logged/resolved.
problem is: I decided to apply some client side validation of the site's forms. The following script will probably trigger some indignation amongst you, but this is my first script, practically copy-pasted from snippets I found on the web.The first few lines of the script is the beginning of the validation function, interrupted by the definition of an alert customizing function. My first question is exactly about the place: did I well place this customizing thing, or could you suggest me a better way to place it?After this definition within a definition, the validation script continues and calls/defines many times the removeCustomAlert function. That's because of my second problem: originally, without the alert-customizing function, after the standard alert box had been closed, the related form field got focused.
But the custom function stopped working after that the customized alert box had been applied, so finally I replaced the focus() function, right inside the removeCustomAlert function. That was the only way I could solve the issue, but gosh, it's many many code. So my second question is: do you know an easier way to code this whole stuff?So, the code is:
function checkForm() {
var cname, cemail, cfname, cfemail, cmessage;
with(window.document.frdForm)
[code]....
How can we identify logical errors from other types of errors?
View 4 Replies View Relatedi'm a newbie on jquery i'm studying it with the latest version, and following a book called "Learning Jquery" but iencountered a error, and i don't know what the problem is:
i copied the code from the book like this:$('a[@href^="mailto:"]').addClass('mailto'); to try to change the links which start with "mailto" to the new class "mailto" but there's a error reported: uncaught exception: Syntax error, unrecognized expression: [@href^="mailto:"]
is there anything wrong with this script as i keep gettin an error message in IE with menu item 1:
//menu methods
function ehandler(event,theobj){
for (var i=1; i<= theobj.numberofmenuitems; i++){
var shutdiv =eval( "menuitem"+i+".thediv");
shutdiv.style.visibility="hidden";
}
theobj.thediv.style.visibility="visible";
this menu is related to a drop down feature later on!
How do I get to see the details of JS errors in IE? I have some problem in IE that isn't showing up in FF or Opera. Is there an error window in IE that I can open up and look at warnings and errors?
View 4 Replies View RelatedI am in a little over my head here trying to make a template for this PHP script. I am trying to work out all javascript errors.
So far I only have one error on the index page and no other pages. In IE8 at the bottom it shows me the little error icon and when I click it, it shows me:
Line: 2
Char: 18579
Error: Object doesn't support this property or method
Code: 0
URL: http://www.mysocialengine.com/demo/woolton/index.php
I am trying to locate this error in the source code, but cannot figure it out. Can someone maybe take a look at the source and point me in the direction to what IE8 is finding as an error? It's weird that there are javascript errors only on the home page when I use the same header and footer file for the entire web site.
Take a look at my code then I'll tell you what error I get...
The element with that id has been created and I still get this error when I try to style it...
My browser is Google Chrome.
I'm using javascript for my client validation and I would like this to work the way I wanted to. I have three textboxes for last name, middle name and firstname. All the fields are mandatory and if the form is submitted there would be an error to display below the textbox. The problem now is I couldn't show three errors at once. I could only show one error at a time. The error msgs are specific that is "Last name required", "First name requiredHere's my JS structure
function validate()
{
if (textbox1 == empty)

When i visit a majority of the pages on Dic i receive the following javascript error:
Webpage error details:
Message:
I am using IE 8 with nothing disabled. The browser also goes into compatabilty mode every time this error happens. The screen will go competely white and i will have to do a refresh to get anything to show up.
I am getting the message in the bottom status bar on my site www.pashmina-shawls.com Done but with errors on page? It doesnt happen on the index page, only on all the other pages, the reason for this is i use a template for all pages except the index page, and all pages using template show this error message, please help and will this effect the functioning of the site?

Having the following line (in the head)...
<script type='text/javascript' src=''></script>
...causes this:
Error: syntax error
Source File: http://cross-browser.loc/toys/toolbars.html
Line: 1
Source Code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
And having the follow line...
<link rel='stylesheet' type='text/css' href=''>
...causes this:
Error: The stylesheet http://cross-browser.loc/toys/toolbars.html was not loaded because its MIME type, "text/html", is not "text/css".
The empty src or href attribute seems to cause it to load itself (the html file) as a script or as css.
I'v just finished the first web site i wrote which encorporates some javascript. It worked fine on my test server, but as soon as i moved it to the production box, I now get all sorts of errors like :Unterminated string constant when i open the first page, and Object expected when i try to call a javascript function by clicking on a menu item. Is there some sort of configuration that must happen on my production box? The same coding works fine on the one server but not on the other.

IE pops them in a modal box and NS has the excellent javascript console.

Page works fine...however I get a little message on the bottom left of the page (on the bar) that says there is an error with the page.
How do I tell the page to tell me what's wrong?
window.onerror is used to catch and supress the script error. but it
will catch the error only when the script is within the same source
file.
for example, consider a html file MainFrame.htm as ....
i'm having problems with my json scripts. When I retrieve data that
contains new lines it causes an error from firebug. I've used a couple
of replace like
.replace("", ""), .replace(//g, "") but it still didn't work.
I'm creating a simple page that consists of a hidden frame and a main page. The main page gets the javascript functions from the hidden frame. One function displays a scrolling message and the other displays an alert. I'm getting two errors, but they are the same one. "top.HIDDEN is null or not an object" on line 3 & 0 (when I click the link).
