AJAX :: Microsoft JScript Runtime Error: 'document.getElementById(...)' Is Null Or Not An Object?
Apr 2, 2010
I am using some AJAX and some JQuery for Login panel animation in Master page.Also in my home page I am using AJAX Tab container.It works fine when I run the application without login.If I logged in I got the following error when I put the breakpoint into my code,
Microsoft JScript runtime error: 'document.getElementById(...)' is null or not an object,It shows at the following Line at the Home[dynamic] page.
I am upgrading a website from .Net 1.1 to .Net 2.0 Framework.My Code is working well in mozilla but the same code is creating one problem in explorerthat is :- "Microsoft JScript runtime error: 'document.Form1.txtScrollY' is null or not an object"It is showing 3 options for every action i do in the net Break , Continue, Ignore.
If i allow all users to access this folder or remove this web.config file, then the ajax toolkit works. I need to protect this folder and i am using form authentication. Could someone point me where i went wrong. Kindly keep in mind that i am new to asp.net.
I had to exclude several pages from my website to get it to run in vs 2008. When I finally got the home page to come up, I tried to type a character into the login box, and at the first character the probelm blows up:
Microsoft JScript runtime error: 'keyCode' is null or not an object
This is insanse. This is the page I'm on when it crashses. Does this have something to do with ajax?
i am using urlrewritingnet for url rewriting. at one of my page i am using auto complete extender . it works fine for first page weirdly because also that page is getting url rewriting.
now let me explain you
my normal page is
domain/Pokedex.aspx
here what i do for url rewriting
[Code]....
ok now problem does not happen when i type this : domain/Pokedex.aspx. but i when i type this problem occurs : domain/Pokedex-2 which is equal to domain/Pokedex.aspx?page=2. here is the problem screen shot but when i type this problem does not happen : domain/Pokedex.aspx?page=2 so it is about url rewriting i guess
My site was woking fine, now i noticed that i get an error "Microsoft JScript runtime error: 'null' is null or not an object" when i checked the view source, i saw the following system generated code
<script type="text/javascript"> var Page_ValidationActive = false; if (typeof(ValidatorOnLoad) == "function") { ValidatorOnLoad(); function ValidatorOnSubmit() { if (Page_ValidationActive) { return ValidatorCommonOnSubmit(); } else { return true; } WebForm_AutoFocus('txtMailAddress');// --> IS THIS RIGHT???? out side the braces??? </script> </form> </body> </HTML>
Modal not showing up when show is called, also error on loading page. Attaching code below, can anyone help me discover my syntax / logic issues here?
NOTE: Did some research on this before posting, some claimed it can be an issue of where the modal is placed on the page in relation to the update panel I am using. I have tried different placements of the modal extender and I also tried removing the update panel all together in hopes to at least see the modal show, no go...same issue. So with that, the issue shouldnt be around the use of the update panel...
Here is the error: icrosoft JScript runtime error: Sys.ArgumentNullException: Value cannot be null. Parameter name: elements

I am trying to use jGrowl in ASP.NET, but am getting a Microsoft JScript runtime error: Object doesn't support this property or method error when trying to run the page in IE.

I am writing a Web Application in ASP.NET using C#. Whenever I run it, I get three types of Runtime Javascript Errors.
My Problem is that even though I am running a new Web Application with out any modification, then I also get the same errors.
These are the errors:
Microsoft JScript runtime error: Object doesn't support this property or method at document.addEventListener("mousemove", updateLastMouseMoveCoordinates, false); Microsoft JScript runtime error: Object expected at divSurveyInit(); Microsoft JScript runtime error: Object doesn't support this property or method at enter code here: document.addEventListener("mousemove", updateLastMouseMoveCoordinates, false);
I used the following function in my ASP.Net Project (which contains ajax controls)
[Code]....
Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
I searched online for solution and got to know its the problem of asp.net ajax. None of solutions (that I found like Add EnableViewState=false, etc.) worked for me.
To demonstrate my issue in ver simple. I have a button in Ajax updatepanel section. When i try to call the script from button click event i am getting the following error.

Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.

I have created an AJAX Server Control Extender which uses the Sys.Timer-object in the client behavior. It worked at first, but suddenly I started to get "Microsoft JScript runtime error: Object expected" when running the page with the extender. When debugging, I see that the line - this._timer = new Sys.Timer(); - in my .js-file which fires the error is the bold line in this function:
