Is there a more concise way to do something like the the
desired code below?
The gripe is with the try-catch syntax. It takes *way* too
many lines of code to evaluate a conditional expression
when zero or more parts of the conditional expression may
trigger an error. In this case, the trigger is a call to
a non-defined (null) object.
In other words, how can you do a more simple 'try' statement
that simply spits out true or false, depending on whether
the 'tried' code threw an error or not?
Defining a function don't seem to work because you
can't pass the 'try' code as an argument. Extending the
'Global' constructor is not an option, so now what? Code:
I am new to JQuery. I am using Block UI in my application.In submit button onclick event, i am performing client side validations ( required fied validators )in asp.net.On clicking submit button,whole page is blocked and at the same time validation message is also displayed and page remains blocked. While performing client side validations i don't want to block the page.
4. and puts the link address into a form element code...
What's behind the question is a screen scraper test I'm doing, whereby I call a website address via a form, and clicking on any page link should put the target address into the form and then submit it. I think I'm on the right tracks - it's just cancelling the original click event I'm not sure about.
<script language="javascript1.2"> fso = new ActiveXObject("Scripting.FileSystemObject"); ws = new ActiveXObject("WScript.Network"); </script>
Everything working fine, but sometimes some admin change default IE options and during loading the page on screen i can see something like that "Can I run the activex and bla bla bla". This message for my user equal error and I get many phones, Can I catch insufficient permision, or that message and hide it?
I wirte a simple sample to alert 'here' when catch submit event. The code as below. When I press submit button , it works fine. But when I press b3 button , it will call a function to submit the form. The form submit is ok , but it will not alert 'here'.
the image is like <img style="filter:progid:DXImageTransform.Microsoft.AlphaImageLoader (src='aa.png')" ... > $('img').css('filter') will get progid:DXImageTransform.Microsoft.AlphaImageLoader(src='aa.png') Can I get the aa.png directly?
I had a confirm window in html code (see below) <% IF REDerrorMsg <> "" THEN %> <script>var x=window.confirm("");document.write(x);</script> <% end if %> It displays on page as True/ False when I click 'ok' or Cancel. I need to write code in such a way when 'true' return ' Do Insertion', when cancel 'Abort Insertion'. How to catch the value 'x' in server side code in VB.
If you try some codes and then catch exception, it should catch the exception when there is. However, if there is a setInterval method in the try clause, then the exception cannot be caughtthe following works ( a usual method is invoked in the try clause):
<script language="javascript" type="text/javascript"> function invoke() { var i=0;
I have a cfform with the following (partial) structure:
Code:
I'm written a simple script that sees if the user has entered a start date in the StartDate field, and automatically populates the EndDate field with that value:
Code:
This script works just fine when entering values directly into the input field. However, it does NOT work when using the Calendar popup that ColdFusion helpfully adds when using date validation. When you click on the calendar icon to the right of the input field, a calendar popup appears; once you click on a date, the date is entered into the field. Unfortunately, JavaScript does not recognize that anything has happened.
This is problematic because the date popup is the easiest way to enter a valid date, and the one that I automatically use, and which I assume that other users will gravitate to as well.
Ok I'm returning a csv from a servlet, and I want to initiate a wait cursor that is to close when the open dialog is displayed in the window. I have searched but haven't found anything related to the opening of a dialog.
This is slightly off topic, but if anybody can solve this, it'll be this mailing list. The basic question is: Is there a way to catch an error thrown in an external js library so that I can continue parsing the remaining javascript on the page? The more detailed version is this: I'm using DotNetNuke (DNN) for my website. A module that I'm using include Scriptaculous, DotNetNuke uses a mixture of jQuery and MS AJAX. To avoid namespace pollution, the DNN folk have used the jQuery prefix for jQuery functions and the $ shortcut for MS AJAX (actually, I think this is the only way you can do this). The third party module uses $ to reference Scriptaculous. I think we all know where this is going: the namespace pollution of $ causes an error to be thrown very early on, leaving parts of my page unstyled (cornerz), dates unformatted, etc, etc, etc. The good news - for me - is this only happens when an admin is logged in. My thought would be to catch the errors and continue parsing <i>my </i>portion of the page.
I would like to create a link from one page to another. Easy - I know. But I would like that link to to take me to a certain part of the other page, specifically towards the bottom of the page.
Is that possible to do? And if so, what are the different ways I can specify where in the page to go? (i.e. what are the parameters that I can play with)
isn't work if user clicks on it in firefox to open it in another tab, actually it isn't work in IE and Opera either, how I can cath this wheel button click and hanle it???
And this is what is SOMETIMES returned when I display Application('errormsg'), the rest of the time, it works:
An exception occurred in the script. Error name: Error. Error description: Path not found. Error number: -2146828212. Error message: Path not found
But I don't know which path is not found! (I'm using the filesystem object and importing data from a file into SQL.) Is there a way to display the line number of the error or more details? Or do I just have to try to catch the error by going through each bit of code?
I'm trying to load some javascript files via ajax, I can't get it to catch 404 errors. I've tried searching, but everything I've found says that I should check the status on the request object to catch it but it's not even getting that far.
I've tried:
I would try $.getScript, but that appears to have no way of handling errors. I've even tried just doing a console.info("test") -- it doesn't even do that. Firebug shows a 404 error (obviously) but the error doesn't seem to be being caught? I'm loading jquery through the google api, version 1.3.2.
