Exception When Calling A DOM Method Using A Reference To It
Jul 20, 2005
In an attempt to answer another question in this group, I've had to resort
to calling the DOM method, Node.removeChild(), using a reference to it
(long story...). That is, passing Node.removeChild.
In Opera (7.23/Win), the call appears to do nothing - the node remains -
but no errors are shown. In Netscape (7.0/Win), an exception results[1].
On IE (6.0/Win), the node is removed.
Strangly, if I pass another function reference, say window.alert or a
user-defined function, there is no problem. This illustrates the problem: Code:
When I call addField(), my table appears to be populated correctly with a new row in the table with all the required fields. However, when I call delete row on any new rows that have been created, I get the following error:
The error appears to happen when the last line of removeField() gets called...specifically rowToDelete.rowIndex throws the exception.
I should mention that I am running this code on Firefox 1.0, however, when I run it on IE6, it doesn't work either, but I don't know what the error is (I just don't know how to get a trace of the JavaScript errors). Code:
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 have an object myscript and from within the method validate, i want to call the method init. so is there there anyway that I can call the method init without having to prefix like this: myscript.init();
This is the first time i'm really using javascript objects (well the first time i've written my own one) so the problem is probably a very simple one...
I've got this:
Code:
When i change the country from the dropdown box i get an error "hometown.setCities is not a function" but the thing is that i can call this in other ways eg from the address bar (javascript:hometown.setCities()) and it works perfectly.
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.
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'm using the following code to refresh an iframe:
[Code]...
The problem is that Zenbox.show () gets called before the src attribute is fully loaded, so the refresh is visible to the user. Is there any way to setup a callback when the iframe.src is fully loaded that I can call Zenbox.show() in ?
I am trying to call a ActiveX object from JSP using the ActiveXObject method in javascript. I have a dll filed named Patchgenerator.dll which is registered and assigned a prog id "Patchgenerator.PatchGen.1" which is being passed as an argument to the ActiveXObject method. Below is the code i am trying to execute..
[Code]...
When i write the above code and save it as an html file it works fine..the activex object is created and the methods are called , but when i copy the same code to a file and save it as jsp file under webapps folder under tomcat it doesnt work and reports a javascript error with the error being: Automation server cant create the object at line : var SSOObj = new ActiveXObject("Patchgenerator.PatchGen.1");
I want to call C# method from jquery. So, I placed those methods in webservice and trying to call from jquery. But, it is giving an error as shown below: Access to restricted URI denied" code: "1012 This is seen from the Firebug console.
and addClickEvent sets the onclick attribute of above mentioned DIV. and in addClickEvent I am explicitely mentioning the name of class object. This means every time I create a Variable with another name I have to Change this function also.
I have a single webpage that contains information on all 50 U.S. states. There are 50 links at the top to jump down to the state you want, and at the bottom of the information for each state a Back to Top link.
I'm making the Back to Top link into something more complex, and it will require three or four lines of code.
So that I don't have to repeat the code 50 times, and create a burden when I need to edit it, I want to place it in a .js file and call it x. Then below the information for each state I'll simply have:
Does calling code from a .js file 50 times slow down the page load? Which method would load faster?
I am opening a blank window and writing a javascript on the new window to submit a form.when I execute a line "newWindow.document.write(newwdtxt2);"(3rd line from last) I get an exception and last two lines do not execute. I see this problem only in IE 6, Code works fine with IE 7.Below mention is my code
function openWindow(url,name,options) { var aToken = ""; aToken ="2121225434349231132674638921:something"; if(aToken=="") { aToken=document.formEMS.AUTHTOKEN.value; } var newWindow = window.open("", name);
The code I am writing fetches a csv file with weather data and updates the contents of the page every 5 seconds. It works correctly as far as I can tell in Firefox, IE, and Chrome. In Safari it works correctly the first time it loads but gives the following error any time after that.
Error: NETWORK_ERR: XMLHttpRequest Exception 101 I've searched for this but couldn't find anything that seemed to be similar to the issue I'm having. The error occurs on the xmlhttp.send(null); line.
Code: function getFile(url) { var file_url = url + '?t=' + ((new Date()).valueOf()); if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest();
Click "other information" in the left, first it's work good. But when I refresh and click "other information" again, I got javascript error: unknown exception.
Has anyone seen the "Exception thrown and not caught" error message while working on some script? I started seeing this the other day, before heading home (too tired to work on it at that time.) I've tracked it down to an AJaX file that is being used by the ColdFusion server I'm working with (it is including a file called "cfajax.js"). Searching Google, it seems that there is an issue with parseJSON. Has anyone determined what could cause this? Or a fix for it? I'm running out of ideas.
I have a puzzling message on my page at URL] It says the API is not loaded. The Firebug gives this: uncaught exception: API not loaded, please pass in a 'site' I wonder which API..
I'm trying to do something, but I don't know if it's possible. Basically, I want to have a public static class method that could access a private object's method. I would like to be able to do :
Class.method(InstanceOfClass);
The method would then access a private function from Class by doing something like
function method(param) { param.privateMethodOfClass(); }
I've done a lot research and experimentations but just can't come up with a solution... I don't even know if what I'm trying to do is possible.
Why is the callwhy is the slice method only a method of an Array instance? The reason why I ask is because if you want to use it for the arguments property of function object, or a string, or an object, or a number instance, you are forced to use Array .prototype slice.call(). And by doing that, you can pass in any type of object instance (Array, Number, String, Object) into it. So why not just default it as a method of all object instances built into the language?In other words, instead of doing this:
function Core(){ var obj = {a : 'a', b : 'b'}; var num = 1;[code]....
//right now none of the above would work but it's more convenient than using the call alternative.
} Core('dom','event','ajax');
Why did the designers of the javascript scripting language make this decision?
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,
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'm trying to develop proper exception handling for a javascript framework I'm developing but I keep hitting an annoying dead end: caller and line numbers / stack trace.I have a basic exception class:
Code:
/** * Exception.js * * @classException
[code].....
The problem is that the console.trace() function returns only one line: "log", referring to ExceptionHandler.log(e) (at least in webkit). What I'd love to do is have the Exception class get information as to (at the very least) what called it and also, although perhaps less viable, the line number it was called on. I don't think the line number is going to work though. I would _like_ this to happen automatically, but if I have to include another argument called_from it won't be the end of the world. I know about arguments.caller but this is depreciated (as of ECMAScript 1.3 (?)).
I have a form button with id="submit". When pressed, ClickGeocode(credentials) is called. This works fine and dandy with: $('submit").click(ClickGeocode) Despite there being no indication that the function takes an argument 'credentials'. So when I want to call the function at some point in my code, I should be able to do something like ClickGeocode(credentials) ... no? However, my issue is that credentials isn't once defined in my code - it is part of Bing Maps function... like so:
function ClickGeocode(credentials) { map.getCredentials(MakeGeocodeRequest); }
So why does it work using .click(), and how can I call the function without user interaction (simply somewhere in my code) even if 'credentials' is not defined?
