CssRules Are Null In Chrome

Jun 12, 2010

This is turning up null all of a sudden. I'm running version 5.0.375.70

alert(document.styleSheets[0].cssRules);

shows null in chrome with a very simple test page and single css file with just one rule, but turns up as an CSSRuleList for FF Safari, Opera etc... document.styleSheets[0].rules is also null in my Chrome browser. How do i get the css rules in chrome? I think this actually used to work in my older versions of chrome but now I'm second guessing myself.

Cannot Set Property Of Null (error Only In Google Chrome)?

Jan 29, 2010

I am using a script called ajax_load.js that defines a function, ajaxpage(), that allows a person to load the contents of an external page into a div item. I have it setup so I may use ajaxpage() to load pages with other div items in it. The problem is that I cannot reference the div items loaded by ajaxpage(). I have provided an example below to illustrate this. It was working fine in the prior version of Google Chrome and is still working fine in IE 8, IE 7, and Firefox. The version of Chrome I am currently using is 4.0.249.78

Here is the example; All the files used in this example are listed below:

74.54.95.210/~admin/js_test/ajaxtest.html
74.54.95.210/~admin/js_test/ajax_load.js
74.54.95.210/~admin/js_test/ajaxtest_external.html
74.54.95.210/~admin/js_test/blank.png

[Code]...

This code was working just fine in the prior stable version of chrome, and still works properly in IE 8, IE 7, and Firefox without any errors (The version of chrome giving me problems is 4.0.249.78). Does anyone know how to go about fixing this? Is this something wrong with the latest version of chrome, or is this on my end? The site I am currently working on relies heavily on this working, and having to change things means altering several thousand lines of code.

CssRules No Longer Works In FireFox 1.5

Jan 22, 2006

I have a WYSIWYG editor based on the HTMLArea project that uses the
cssRules object of a stylesheet to add/update stylesheet rules for
table cells. Ever since I upgraded to FireFox 1.5, I get the following
error message when trying to access the cssRules object:

"Access to restricted URI denied"

The code I am trying to execute looks like this:

var currStyleSheet = editor._doc.styleSheets[0];
var currRules = currStyleSheet.cssRules;
var tdIndex = currRules.length;
for(i = 0; i < currRules.length; i++) {
if(currStyleSheet.cssRules.item(i).type == 1) {
//if it is a style rule
var currRule = currRules.item(i)
if (currRule.selectorText.toLowerCase() == "td") {
tdIndex = i;
}
}

}

This code is simply looking for any rules for TD elements. I am at a
loss as to what is going on and/or what changed if FireFox to cause
this error. It worked fine in previous releases of FireFox. The
document that I am trying to access the stylesheet for is within an
IFRAME, which is what I believe is causing the problem.

Null Is Null Or Not An Object Swfobject

Jul 30, 2011

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

IE6 Error 'null' Is Null Or Not An Object?

Feb 3, 2010

I've been trying for hours and I can't figure out why IE6 is throwing an derror on the following line of code.

Code:
var parts = rgbString.match(/^rgb((d+),s*(d+),s*(d+))$/); This is the function:

Code:
function rgbToHex(rgbString)
{
var parts = rgbString.match(/^rgb((d+),s*(d+),s*(d+))$/);[code]....

And this is the error:'null' is null or not an object

Null Variable - Error: "cobj1 Is Null"

Feb 26, 2009

I put a long script but the problem is small.

var book1 = bobj1.value;
var chapter1 = cobj1.value;
var verse1 = vobj1.value;
var book2 = bobj2.value;
var chapter2 = cobj2.value;
var verse2 = vobj2.value;
[Code].....

I don't know if this is written properly: if(bcv[a]!= ""){ The reason this is happening is because the error shows: Error: cobj1 is null Source File: [URL]

Null Reg Exp

Sep 15, 2004

I have this reg exp

var queryAdd = /?stationval=([^&]+)/.exec(url)

it should return

queryAdd[0] = '?id=AY'
queryAdd[1] = 'AY'

which works fine, as long as there is a stationval in the url, but if the user has not yet specified it stationval= nothing, which is throwing the script saying that 0 is null or not an object.

How do I catch this eventuality? I have tried if(queryAdd[0]==0) and if(queryAdd[0]==null) but get the same error

Using Null In If Statement

Jul 20, 2005

I remember using if statements with null in it. For example, at one
point I used this:

if (value == null) {
value = "something";
}

document.write(value)

However, this script causes an error in any browser. Why can't it
correct the value like it should?

CreateElementNS And Null?

Jun 14, 2005

When are you allowed to use null as a namespace in functions like createElementNS? Most of the time you see people using a namespace all the time or null all the time. But I can't seem to find a real rule...

I use the xhtml-namespace for xhtml and the svg-namespace for svg, but I saw a lot of examples using 'null' as a namespace... Is that allowed?

Why Does IE See Null In This For...in Loop

Nov 17, 2010

After getting a cryptic "Object required" error from all IE's (6,7,8), I tracked it down. It seemed to be coming from my library, line 134 in bold

Code:

Basis.hasClass = function(target, classValue) {
var pattern = new RegExp('(^| )' + classValue + '( |$)');
if (pattern.test(target.className)) {

[code]....

The Typekiezen is a weird one; if there's a nicer/better way of writing that, that would be nice, but it happens this form input does several things when it's clicked... the others only bring up an associated value for the option chosen so they're simpler.Does anyone know why IE can't read this " document.getElementById(Begrafenis.kosten[input.id][val].hide[result])" ...or another way I could write it so that IE does get it. Basically, the code needs to grab the ID's "Postal" and "Box" so the show/hide scripts can DoStuff to them.

Even if I do a bit of
if (value !== null) {
Basis.add/removeClass(value, 'none');
}

this still isn't going get IE to do the right thing, just remove the error.

Null Or Not An Object Using Frames

Jul 23, 2005

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:

Document.getElementById Comes Out NULL Help!

Jul 20, 2005

Basically i'm trying to draw a box over an image which
is turning out to be a nightmare. The problem i'm getting at the moment
is that i'm creating a line with <div which works when it's not hidden
but I need to be able to make it hidden so I can use layers to show all
when it finished drawing to make it smoother. This is how some other
scripts are doing it that i've seen. So i've got it drawing a line and I
need getElementById to pick out the layer but it's only picking out NULL
with the one i've got enabled below. I've tried the others but they just
come out as errors. I need to get top2 which is the <div line to show
itself but I can't seem to reference it by getElementById. I use linux
mozilla so i need it working in mozilla as well as windows that's why
i'm using getElementById. My code is below any ideas anyone?
