Em "'undefined' Is Null Or Not An Object" Only In IE?
Mar 31, 2010
I would like to ask your help regarding this damned error message that comes out only in Internet Explorer and makes impossible to submit the form.The javascript code is:
// JavaScript Document
function checkForm() {
var cname,
I have come across an issue that only happens with IE.I have a custom save function that is designed to handle different ajax submits but I will simplify it for debugging. The issue is that once I make a submit everthing is fine at first. Then once I try to submit a second time it craps out. I am checking to see if there is an onsubmit function and then executing it like so before continuing. After the inital submit it is no longer found. When I alert the typeof document on the form it returns object but when I add the onsubmit it says object expected or object is null or undefined.
Code:
function secureBarSubmit(formId) { alert(typeof document.getElementById(formId)); // object always alert(typeof document.getElementById(formId).onsubmit); // func first time then it is broken
Its an AJAX script which create mulitple choice dropdown boxes connected to a database. the Javascript works great on both FF and IE. However, in IE i get the irritating error code:
I am trying to track down why this custom validator is failing with an error that args is undefined. There are two funnctions - one works and one does not.the bold italicized item is where the error is being generated.Function validHygieneNote works as expected however.
I have a bug that is only seeming to effect IE 8.Also has a weird display issue in IE8, but not in "compatibility view", which the bug may fix. Works and looks beautiful is Safari and Firefox.
I started getting a wierd problem with my jscript program. Here im using jscript for client-side validation and upon email field submission,im getting undefined value with an error saying "length is null or not an object". All the values of fields prior to that are being obtained properly.
im having a little difficulty checking if an XML node has a value, here the code:
var Divs=new Array("artist","bio","img","date","tickets","venue","street","city","country","headliner"); xmlDoc=xmlhttp.responseXML; for ( nodes in Divs )
[code]....
This always throws up the error: document.getElementById(Divs[nodes]) is null ive tried putting the xmlDoc in a variable then checking if its null but no luck, also tried the same method against "undefined" but no luck either.
I did find the javascript twice in my code, once in the header and once here, so i removed it from the header. I also changed to src to the full url. But i am still getting this and i dont know why. the file is located in the root directory. found a solution. basically Internet Explorer is crappy and doesnt like the setAttribute property so had to change the onchange handler by directly changing the attrbute for the object like so.object.onchange = function() {}i have no idea what they means, does that mean i need to change swfobject.js or does that mean i have to change my xml request. and if it is the swfobject i have no clue what they mean or what lines
Whenever i try to use this function it gives me either -NaN, or undefinedwhat am i doing wrong? The objective of these functions are to change x and y coordinates into SAN (Simplified Algebraic Notation) for use in the Chess Game's DataFile (PGN file format).Live Running DHTML App:http://daomingjin.googlepages.com/ChessManager.html140kb Zip-Archive:http://daomingjin.googlepages.com/ScoreMatev1.ziphere are the functions in Question:
function XCoordToSAN(x) { // Convert the x coordinate of the piece to partial SAN (Simplified Algebraic Notation)
I'm getting an error message that says that my function is null or undefined. I figure it' something simple, like maybe a ( instead of {, but I can't seem to find it.
Here's the script from the header: Code: <script type="text/javascript"> var time = new Date(); var dayNight = time.getHours(); function displayImage() { if (dayNight >= 9 && dayNight <= 14) { .....
And from the body: Code: <body onload="displayImage()"> <div> <img id="highlights" src="" alt=""/> </div> </body>
My code is in the attachment alex.txt.When i press the button for first time it gives me error: 'null' is null or not an object. But when i press it again or refresh the page and press the button it gives me the result that i expect.When i change the var pdbfile1,2,3 values(for example with 2x4n;3gis;1crn) and press the button again there is the error again and i have to refresh the page again.
I have a site that is supposed to be 'real-time' which has a frameset of 2 rows (the bottom row is 1 pixel so essentially invisible to IE users which is the requirement for the product). The bottom frame refreshes using an http-refresh every 15 seconds. If new data is available on the server, it tells the top page to refresh. For checks and balances, the top frame has a form at the bottom of the page with a 'clockBox'..which is essentially a text box that gets updated every second so it looks like a timer. When the bottom frame refreshes, it waits 5 seconds then resets the top counter to 0. The top counter continues to count. If the top counter gets to 30 (which it never should unless the bottom frame gets stuck), it refreshes the bottom frame. Code:
this following code is having some problem in checkbox.length or checkbox.checked. this problem exists only in IE browser, in mozilla its working fine....... i have to delete a row on click on checkbox...
var v_checkbox = document.form3.check; var nb_checked = 0; var tbl = document.getElementById(id);[code]....
I am getting an error on this code - sometimes! - and I'm not sure what it is. If I run this as is there is no error. If I add it into another page with other stuff it's ok for a while and then I get an error. So, I added my new page block my block to this code and waited for the error to appear so I could determine a conflict - but it was fine. And then a few clicks later the error.
This is the error in IE. In Firefox it seems to be fine.
The function is simply called in an onclick event. you can ignore the for loop that all works fine, that just swaps some images in a list.
But the line that is causing the problem is supposed to insert the id of the element that called the function into the input 'ratingField'
What is wrong with this line of code? the debugger says 'is null or not an object'
There is nothing wrong with star.id it is used elsewhere in the function and definately contains a value so I think the problem might be with the ratingInput.value part or the line
I hope someone can tell me why this is not working. I have a form that dynamically creates the code below. This is for one product and there are about 10 to 50 products that are listed depending on what manufacturer the user selects. After "buying" a few products (4-8) they user gets the error message: 'QUANTITY.value' is null or not an object.
Do you see a workaround/fix for this?
I posted this on February 19, 2004 under the title 'value is null or not an object -- after a few submits' and received some syntax tips. The formatting has been applied and I hope someone can offer some programmatic help.
I am getting this error on IE8; it is working nice on firefox, and I have to support IE. I found this page: [URL] And they identify as the problem occurring here: The error occurs in the 'install' function right here:
<quote from link> var node = msg.jquery ? msg[0] : msg; var data = {}; $(el).data('blockUI.history', data);
