I am trying to make a canvas element display an image with some text on using canvas.drawImage and canvas.fillText. Only problem is my code is generating a very odd and hard to debug error.
View 2 RepliesI keep getting a syntax error on line 3 and 4 of this very simple script. Normally firebug would give me enough info to fix this but jQuery escapes me. I can see no reason for the errors.
<script type="text/javascript">
$(".shipping-switch[name='shipping_switch']").click(function(){
var selector = "div#sub-address";
if($(this).val() === "1"){
$(selector).slideDown("fast");
} else {
$(selector).slideUp("fast");
}});
</script>

View 1 Replies View RelatedWhat is the best way to debug javascripts? Do it in Visual Interdev? Or just look at if any errors come from browsers.
View 2 Replies View RelatedWhen you write html or css then the validation proces is a good way of
finding errors. I get some syntax error / code: 0 errors in IE, how can

Is there any way to debug javascript in a web application? When I
develop JSP pages, and it has the javascript code in it. The problem is
the debugger in Java IDE (WSAD in my case) can only debug Java code but
not Javascript code.
What should I do to debug javascript code?
I've written several scripts that have "while" blocks which increment a
date by one day if the date does not match one of a group of dates.
However, sometimes it apparently steps out out the while loop even
though my condition isn't met. Will work for a few loops then steps out
often.
Are there javascript "date" issues? I have also noticed different
results between Firefox and Internet Explorer.
New to javascript and still getting my head around strings...
Consider the following line of code...
var path = location.pathname;
....after execution, the variable "path" contains something like
"file:///C:/Documents%20and%20Settings/user/Desktop/Test/fileread.htm"
How do I parse this down to "C:Documents and SettingsuserDesktopTest"
....or at least to "C:/Documents%20and%20Settings/user/Desktop/Test"
Is there a better function to retrieve the source folder containing the
current HTML document?
I need to know the path to the current folder to reference other files in
the same directory using a FileSystemObject.
I want to delete some lines on the canvas that i have created in HTML5 (with the <canvas> tag). I know one solution and that is using clearRect() (give this function the HEIGHT and WIDTH of the canvas and you clears the whole canvas.).But i don't want to clear the whole canvas, i only want to delete a few lines made by the function lineTo().
View 1 Replies View RelatedI have a menu in which is applied typeface script. Typeface 0.11 version doesn't support hover on links. There is an experimental version but doesn't work very well for me, so i tried to implement hover by myself.
Problem is: hover works pretty well changing canvas context property fillColor and then calling fill(), but the stroke on hovered voice remains on another color. Difficult to explain, so i put some test code online: TEST CODE As you can see, passing with mouse on the menu voices triggers the hover and the element change, but remains bordered in red.

I am using the Inline Form Validation Engine jQuery plugin found here [URL], and though I have posted at their forum as well, am having a heck of a time (not being well versed in js OR Ajax, unfortunately)
All I need to do is edit the code so that when the onSubmit function is processed, it returns only the first error it encounters, rather than keeping and display the array of every error. I have picked through the code several times, and can't seem to find where the array is stored. I thought perhaps I could find a for loop to limit, but am at a complete loss.

im not a developer but i enjoy the time i spend figuring out this kinda stuff.
I am working on an ASP.NET application that make a lot of jquery and javascript calls and trying to optimize the client side code as much as possible. (This web application is only designed to run on special hardware that has very low memory and processing power.)
The profiler in firebug is great for figuring out what calls are taking up the most time. I have already optimized a lot of my selectors and it is much faster.
However the profile shows a lot of jquery error() calls. In the attached image of the firebug profile window you can see it was called 52 times, accounting for 15.4 of the processing time.
Is that normal for jquery to call its error() like that? My code works flawlessy, and there are no error messages in the firefox error console. It seems like that is a significant performance hit. Is there anyway to get more info on what the errors are?

I have a problem with javascript in IE6/IE7, or specifically with jQuery. There is a page that uses the google maps API which shows an error when you navigate to the website and the page remains blank. When I press refresh I get no error and the page loads as it's supposed to (this happens only ie IE6, IE7/8 appear to work fine). The same thing happens with tinymce and the jquery.tinymce.js plugin, which gives an error in IE6/7 but not in IE8. I can't post the URL since it's a password protected "under construction" website. The error for the Google Maps Api I get in IE6 is
Code:
Line: 215
Char: 26
Error: 'firstChild' is null or not an object
Code: 0
URL: -- left out --
And the error for TinyMCE in IE7 starts with
Code:
Line: 53
Char: 3
Error: Permission denied
Code: 0
URL: --left out--
And then when I press "yes" for "Do you want to continue running scripts on this page?" I get
Code:
Line: 19
Char: 7
Error: 'tinymce' is undefined
Code: 0
URL: --left out--
The google maps api page uses $(document).ready( fn ), while TinyMCE uses window.onload. And, as one would expect, in FF, Opera and Chrome all works fine.
I'm trying to write a custom display for the error messages on my form. Ideally I'd like to use a modal pop-up window to display the errors, but I'm having trouble figuring out how to prevent the validation plugin from automatically displaying the errors on my page AND I can't quite figure out how to access the individual error messages for the elements on my form. What I want to do is to allow users to save invalid forms, but to warn them that they are invalid to make them confirm that they want to save. [code]...

View 2 Replies View RelatedI am trying to use Accordion Content script v1.7 from DynamicDrive.com on some pages. I have set up a test page to show the error messages. I have changed the doctype of the page several times, including the exact one they use on the sample/instruction page on DD, but no luck. It is also throwing an error of undefined var ddaccordion, which is defined in ddaccordion.js, which is the JS file that goes with sample page , which is located in the same directory.
View 1 Replies View RelatedI'm using the jQuery form validation plugin along with the fileinput plugin which hides the initial input area, but uses <divs> and some styling /javascript to show the file input field.The issue I am having, is that the 'this field is required' text that is meant to show on submission, doesn't come up for the file input field, nor some checkboxes that I have in a table. I am guessing that this is because the code is needing the label to be RIGHT next to the element (in this case the file input or the checkbox) in order for the validation message to show..Are there any work arounds that anyone knows of so that I can get the error message to show?Is there a way to show the error message for required fields when they have a div wrapping them or anything wrapping them?

I finally found code that actually works. I click on the button, and the table disappears. I click on the button again, and it reappears. Like magic! I have two problems still.
(1) When I click on the table, it disappears, but the space that it was in is still empty. When it retracts, I want the rest of the text to retract with it (not disappearing text--i.e. have the text occupy the space where the table was, and move back when the table reappears. note: the text is directly below the table); otherwise, what is the point of a show/hide button? It's meant to save some space.
(2) I want the text of the show/hide button to change to "Show" when the table is not present. Code:
I'm using input hidden control's value in the javascript function.
same code is working fine on all other browser except a specific
version of safari(i.e.: MAC OS 10.3.7 and Safari 1.2.4).
problem:
control's value is not getting displaying at the first time
when the page gets load, although the same piece of code would work if
I just refresh the page, strage.
declaration of hidden control:
<INPUT id="hSliders" type="hidden" runat="server">
javascript code which is calling the value of hSliders:
alert(document.Form1.hSliders.value)
this alert is showing nothing although it should display string.
i check the view source also control's value is getting populated.
I'm having a problem showing the output of this code in the textfield.
<html>
<head>
<script language="JavaScript">
<!--
var url = document.URL;
-->
</script>
</head>
<body>
<textarea style="overflow: auto;" rows="1" cols="70" wrap="off" readonly>
<script language="JavaScript">document.write(url);</script>
</textarea>
<br><br>
<script language="JavaScript">document.write(url);</script>

The output isn't showing the browsers current URL which is the desired effect, instead it is only showing the raw JavaScript code.
I've been using the most recent version of cluetip 0.9.9.c and I have overridden error function in the cluetip, but I was wondering how I
can hide the actual cluetip? I tried $(this).isActive = false but this didn't work.
error: function(xhr, textStatus) {
/// HIDE THE TOOLTIP?
}
Basically I got a check in the error function that checks whether to show the error or redirect to the login page in case I have forms
authentication. So how can I hide the tooltip?
