JQuery :: How To Supply XHR Exception Object To Ajax Function
Aug 21, 2009
I've been using $.get() and $.post() extensively, but then noticed the more functional $.ajax, which lets you handle server-side errors using the "error" option. The parameters to the callback function for the error option are:
(xhr, status, exception), where in the documentation it says "exception" is the Exception object if it's supplied.
My server-side is PHP, and when I perform a:
throw new Exception("You can't do that!")
or
trigger_error("You can't do that!", E_USER_ERROR)
It does run my error callback, but it puts 'undefined' in the "exception" object, and my custom error message is nowhere to be found. How do I populate that Exception object on the server side, so that the error callback can then access it?
In my code (ASP.NET MVC using Nhibernate) , I do this :
[Code].....
Then I display the result in the DIV named "myFormDOFF" Of course, my .NET code can generate exception. I'd like when I receive an exception didn't change the content of "myFormDOFF" but display the message send by the exception in another DIV.
How might I go about getting the parsed JSON object in the complete function? The json param shown below seems to just receive the http status text message.
My 2nd question would be how should I knwo if the first place what params I can receive to a callback function like this?
I am needing some help with an error I'm getting from a project I'm working on. First off let me preface this all with the fact that I'm a total javascript noob. I'm really trying to understand what I'm doing wrong. So any help or advice is MORE than welcome. Here's what is happening. I found this code that will duplicate a row in a table and modifiy the name of a input in the row. Well for my purposes I have two different tables I need to work with. (each one idividually) So I changed the code a bit to make it accecpt a variable to use for the table name. (before it was static) and now I'm getting a error. Error: uncaught exception: [Exception... "Component returned failure code: 0x80004003 (NS_ERROR_INVALID_POINTER)" nsresult: "0x80004003 (NS_ERROR_INVALID_POINTER)" location: "JS frame :: http://www.tourandtravelnow.com/admin/scripts/faxPageScript.js :: addRow :: line 14" data: no] This is the old code that would work (only for one of the tables)
I am having trouble getting my expanding menu to work in Firefox and Opera. It works fine in IE though. I did not write the javascript myself, as I am fairly new to JS, but I did all the HTML and CSS. I used the error console on FF, and also used FireBug. They both returned the following error:
I am making a small gallery script. When a user clicks an image, I would like for a function to be called that tells the browser where that image is located in an object. For example:
[Code]...
It works, I just don't like it because it is messy and it seems sensible that some workaround exists.
Ive tried several approaches and even copy/pasted from [URL] Im using Google Chrome 5.0.375.70 beta and the error is always the same: Error: INVALID_STATE_ERR: DOM Exception 11 when debugging the client side I see the readyState is always 0 (connecting), no other error is shown. The server is set to output anything that it receives and in this case it doesnt seem to be getting anything. Checked firewalls and that shouldnt be a problem. Its worth noticing that one time it did connect, and I was able to "chat" with the server, refreshed the browser and never again, restarted the server and nothing. I havent made any change in the code prior to the refresh so really dont know what could be it...
Can assign a new function to a built-in object in Firefox:
But IE and Opera don't have a MouseEvent or HTMLElement that can be set up in the same way. Can you do this in IE or Opera, or just Firefox, and maybe Webkit?
I'm a newbie jquery user so I may be doing something wrong, but I'm doing it well. My use case tells that I need to send files to server and the server will throw an Excption when the file type is unkwown. We are only accepting text files such as word, so a movie will get the mentioned exception.
It works on firefox, but on IE8 (and maybe others) I get a blank page since the line below gets a "Access Denied". It seems that the iframe that jquery builds gets inconsistent.
Couple questions for the jQuery internals-aware folks. This is a bit long, sorry for that. I'm working on beefing up error handling in a web application. I want to ensure that I'm catching all exceptions and handling them via my own UI system. The window.onerror function is part of the solution,
I'm getting a warning message from internet explorer's javascript debugger for jquery.min.js (I load the most recent version from Google's CDN):

I am able to run below code in IE but not in FireFox. Script : var prodElement = document.getElementById('moveattrribseq '); var value = " "; prodElement .add(new Option(value,value)); : This not working in FireFox
I find ajax with jquery more confusing than with regular JS, b/c in jQuery you don't declare XMLHttpRequest object.. so how do you do something like:
In example I mention here,[url] namely [url] I don't understand where var 'msg' is declared, I know it comes from the back-end, but HOW is it passed to the front-end? (how do you do this w/o responseText or something similar?)
I'm trying to connect to a send-mail jsp with ajax.. the email is not getting sent.. I want to test if the ajax connection is being made at all.. don't know how do it w/o something like xmlHttp.responseText
This is my jQuery ajax code for connecting to send-email jsp:
var dataToSend = "name=sName&email=sEmail&msg=sMsg;
I want to add a color change to an anchor tag. But only on a few pages. I am trying this but it does not work: $(function(){ var urlName = [URL] if (urlName == window.location.href) { $('.news-list-item > h3 > a:first').css('color','#8CAAC3').css('text-decoration','underline'); }});
I was using jquery-1.3.2.min.js to show a modal dialog on a button click event handler and this worked fine. The same did not work with jquery-1.4.2.min.js and yielded the following script error on my IE -8 broswer. Message: Exception thrown and not caught Line: 75 Char: 399
I am trying to access my own JS object from within an ajax call, and can't figure out how to get it to work Whenever I access "this" in the function, it returns the ajax context and not my JS object context. My code looks something like this. I have a Zone object defined in a JS file like this:
Lots of submenus and such, and just can't get this going. Works fine if I remove the submenu aspects of the script, however with these, it returns the error: uncaught exception: Syntax error, unrecognized expression: #
When I upgraded to jQuery 1.7.1 (from 1.5.x), I found that an exception was suddenly thrown on every keydown event on an INPUT type="text". I still get the exception when I remove my change and keyup events. Previously I bound to these elements with .live, but I have the same issue with the new .on, so I don't think this problem is even related to my bindings.
The exception is as follows (from the custom WebKit frame where my script runs):
This occurs on line 3255 of jquery-dev-1.7.1.js, which reads:
I did some poking around and found that handleObj.origType is "keydown". There is no jQuery.event.special["keydown"] defined, meaning that the first part of the expression evaluates to undefined (there is no such thing as {}.handle). The second part of the expression, handleObj.handler, evaluates to true. The entire expression therefore evaluates to true, which can't be applied as a function.
Theexpression in red works fine in jQuery 1.2.6 but does not in 1.4.2.
jQuery( "#menu_sample > li > a[@class=expanded]").find("+ ul").slideToggle("medium"); All the child li items for the following HTML should display: < li><a class="expanded" href="#">Weather</a><ul> (li items here) [Code]...
When a pending ajax request is aborted in IE browsers there is a new global object called "jQuery" + timestamp, for example "jQuery16405272192696596443".
This happens in every IE from 6 to 9 but not in Chrome, Safari, FireFox in their current stable versions. I am a bit lost and found nothing similar. I created a little test page to determine whether it started due to some own code or just in this little piece.
