JavaScript - Script438: Object Doesn't Support Property Or Method 'keys' For Ie
I found strange for the following code:
Code: var allextRules = Ext.util.CSS.getRules();
Object.keys(allextRules).forEach(function(key) {
var keyname = key;
if(keyname.indexOf("js") != -1){
Ext.util.CSS.removeStyleSheet(keyname);
console.log(keyname + " Removed");
}
});
When the above work is tested in other browser (say - Google Chrome), there is no error. However, when tested in IE 9, there is error as follows: Code: SCRIPT438: Object doesn't support property or method 'keys' According to this article (https://developer.mozilla.org/en/Jav...ts/Object/keys), the Object.keys is supported by IE. Have I miss out something? Similar TutorialsMy website is working perfectly on Firefox but when I visit it with IE(7), I get the following errors and some things aren't where they're supposed to be.

plz help me Hi All, Need some urgent. We are having a javascript which is throwing the foll error "Object doesn't support this property or method". The javascript function being called is using a Scanner API. So this is using some ActiveX. Below is the code for javascript <script language="javascript"> // Initialize scanning function OnLoad() { try { Scanner.OpenScanner(); // Scanner.ScanPriority = 0; // Set scanner to Foreground Read mode before enable scanning // Scanner.EnableScanning(1); document.forms["mobileform"]["rm07m-bwartwe[1]"].value = "101"; } catch (e) { alert(e.message); } } // Clean up function OnUnload() { Scanner.CloseScanner(); // Calling Dispose is necessary for Pocket IE because of a Microsoft issue related to releasing object. if (navigator.appName == "Microsoft Pocket Internet Explorer") Scanner.Dispose(); } // Scan through soft trigger function Scan() { try { Scanner.SetSoftTrigger(1); } catch (e) { alert(e.message); } } //User-defined function to format error codes. //VBScript has a Hex() function but JScript does not. function hex(nmb) { if (nmb > 0) return nmb.toString(16); else return (nmb + 0x100000000).toString(16); } </script> There is a object tag in html <object id="Scanner"></object> The javascript functions are called from body tag.

I've been having trouble with one of the plugins and have started the debugging process and noticed that the page the problem is occurring on shows a few java-script errors. http://proshotsrange.com/test-contact-page/ What do the "Object Not Supported" errors mean - and what would it entail to fix them? Thanks in advance.

Firstly I am not trying to set onclick by calling setAttribute, which most of the posts describe. I am simply assigning a value to the onclick attribute of the element, which those posts seem to imply. Specifically I am getting "Object doesn't support this action" on the following line: Code: editButton.onclick = editCitation; editCitation is already a function, so I do not see why I should have to wrap it in an anonymous function wrapper to get IE to permit the assignment. Hello just a quick problem with a seemingly difficult solution that I'm not aware throughout. What I'm attempting to do is increment a value when the mouse hovers over the element by using this move_right function: Code: function Move_Right( event, element, number) {
number++;
var elem = document.getElementById(element);
elem.style.right = number + "px";
}
inside the mouseover event trigger function which I figured out. The problem is it doesn't move incrementally only once every mouse hover no matter the technique of setInterval(); and or setTimeout(); also ontop of this problem I'm getting errors like : 2014-10-12 20:07:57.785Uncaught TypeError: Cannot read property 'style' of null even after the changes I made also after this original function call : This is the current code so far which is different to the previous code above "obviously" : Edit fiddle - JSFiddle Thanks if someone knows the issues here, I hope it makes sense . Hi all, I was under the impression that I and object/associative array could have other objects as the keys for properties. That is, I should be able to set myObject[anotherObject] = 1. However, while this seems to work at first glance, any new object I set as a property key overwrites the first one. Here is the result of me testing in my Chrome console: Code: > var obj1 = new Object();
> var obj1.someProperty = "test"
"test"
> var obj2 = new Object();
> obj2.someOtherProperty = "test2"
"test2"
> obj1 == obj2
false
> obj1 === obj2 // the two objects I created are definitely not the same
false
> x = {}
> x[obj1] = 0 // set the two objs as property keys on x
0
> x[obj2] = 1
1
> x[obj1]
1 // blargh! x.obj2 overwrote x.obj1!
Any idea if this is possible, and if I'm just messing up with something dumb? Hi, I am trying to run multiple videos in the JW player by clicking on different links.Its working fine in chrome and firefox, But it doesn't play viseos in IE.

Its working well in FF and chrome. you can test it there. http://www.internetindustryawards.co.nz/2010.html Its really urgent... Is there a way to redirect your site to another site if the browser doesn't support HTML 5? So, if you where using an old version of IE or Firefox that didn't support HTML 5 it would redirect them to another page. Hello, Into an external js file, I'm trying to use the facebook graph api to read values of "shares" and "comments" and import them into js variables. As example, using http://graph.facebook.com/?id=http://www.google.com in the browser, I get the following response: Code: {
"id": "http://www.google.com",
"shares": 3208837,
"comments": 2
}
In my js code, I need something like: var val_shares=xx; var val_comments=xx; Here's the code I'm using to (try) do it: Code: function getNewHTTPObject()
{
var xmlhttp;
/** Special IE only code ... */
/*@cc_on
@if (@_jscript_version >= 5)
try
{
xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
}
catch (e)
{
try
{
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
}
catch (E)
{
xmlhttp = false;
}
}
@else
xmlhttp = false;
@end @*/
/** Every other browser on the planet */
if (!xmlhttp && typeof XMLHttpRequest != 'undefined')
{
try
{
xmlhttp = new XMLHttpRequest();
}
catch (e)
{
xmlhttp = false;
}
}
return xmlhttp;
}
var xmlHttp = getNewHTTPObject();
function getDynamicData()
{
var url = "http://graph.facebook.com/?id=http://www.google.com";
xmlHttp.open('GET', url, true);
xmlHttp.onreadystatechange = callbackFunction;
xmlHttp.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
xmlHttp.send(null);
}
var syndLinkRequest = getNewHTTPObject();
function callbackFunction()
{
if (syndLinkRequest.readyState != 4)
return;
var result = xmlHttp.responseText;
}
into the HTML I call getDynamicData() at <body onload=getDynamicData()>... Using Firefox in console mode, I see that the results arrive at this point of code: Code: xmlHttp.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
xmlHttp.send(null);
But I do not know (or understand) how and where to get those value to associate them to a js variable. I understood I will need to use json to achieve this but I don't know where to start. In addition, I can't use jQuery or php to do it. After 2 days of searches, I'm about to give up. Does anyone have an idea how to do or where I can find a concrete sample to show me the right way ? Thanks a lot. Gino Hey, this error ONLY occurs in IE. "Unexpected call to method or property access." I pinpointed it to this line: o.appendChild(e); The full function is: Code: function aO(d, t, src, p, id ){
alert('aO has begun.');
var o, e, i;
if (!ie){ o = cE('object');o.data = src; }
else { o = cE('embed');o.src = src; }
o.id = id;
if (!ie){ p.push( ['movie', src] ); }
if ( typeof(id) === 'String' ){o.id = id;}
o.type = t;
o.style.width = '210px';
for(i = 0; i < p.length; i++){
e = cE('param');
e.name = p[i][0];
e.value = p[i][1];
o.appendChild(e);
}
d.appendChild(o);
alert('aO has finished.');
}
What it does is write a flash object to the page. The FULL code is: Code: <!-- Chat Options -->

Can anyone tell me how to fix this? This is ridiculously irritating, and it's important that I can fix it ASAP. Hi, I'm a newbie to the forum and jquery and have been trying to use it for a slick form wizard i found here. http://thecodemine.org/ It's almost complete but IE keeps giving me an error I've tried everything to fix with no luck. I'm using jquery-1.4.2.min.js and the error it's giving me is Unexpected call to method or property access. line 103 character 460 The code it highlights is: Code: {this.nodeType===1&&this.appendChild(a)})},
at the end of this line. Complete line is: Code: wrapInner:function(a){if(c.isFunction(a))return this.each(function(b){c(this).wrapInner(a.call(this,b))});return this.each(function(){var b=c(this),d=b.contents();d.length?d.wrapAll(a):b.append(a)})},wrap:function(a){return this.each(function(){c(this).wrapAll(a)})},unwrap:function(){return this.parent().each(function(){c.nodeName(this,"body")||c(this).replaceWith(this.childNodes)}).end()},append:function(){return this.domManip(arguments,true,function(a){this.nodeType===1&&this.appendChild(a)})},
Any help would be greatly appreciated. Thanks!

This object is initialized when the page loads, and a function reads the total number of pages by getting the maximum number of the "page" property across elements. Later, the object is accessed by thenextQuestion() function which uses the "page" property to looks whether each element belongs on the current page , then reads out the properties and presents the question. This works okay. Now the tricky bit: For some questions, their text should be different depending on which case is currently on the screen (Change[curCase]). curCase is different on each page, an integer between 0 and Change.length. I cannot get this to work for the Questions object, probably because the Questions object has been already initialized when the page loaded. How can I get my function nextQuestion() to "re-evaluate" the property "question" for all the elements of the Questions objectwhen nextQuestion() is called , using the current value of "curCase"? nextQuestion() is longer, but the (i think!) crucial bits are he Look whether question belongs on current page and push it onto new array: Code: for (i=0; i < Questions.length; i++) {
Questions[i].page = Questions[i].page;
if ( Questions[i].page == BlockNum ) { // if the q belongs on the current page
QuestionsObjectThisPage.push(Questions[i]);
}
}
Then, extract an array containing the questions, which will then be presented: Code: for (i=0; i < QuestionsObjectThisPage.length; i++) {
QuestionsThisPage.push(QuestionsObjectThisPage[i].question) ;
}
So what I'm looking for is something to change either of these two Object.push() functions so they don't simply take the value they find in the Questions (or QuestionsThisPage) object, but to re-evaluate the code for the "questions" property, taking into account the current value of curCase Phew. I found that really hard to describe; hope it's somewhat clear. Hello, how can I make the following object work properly so when I use 'layers.photo1.layer' a jQuery element is returned rather than the text of the function as it is now. I also need to be able to find the element by the photo1 object its contained in not have to input a string there so that I can also reuse it in the background layer. Code: var layers = {
photo1 : {
layer: function() { return $(element).find($('photo1'))}
},
background : {
layer: function() { return $(element).find($('background'))}
}
}
Thx Very Much! I'm using closure to make a function return an object in the form of the literal. Code: function myFunction() {
return {
a : 'foo',
b : 'bar',
c : 'baz',
d : this.a
}
}
I'd want the d property to be equal to "foo". However, when I do that, "this" is tied to the global namespace as opposed to the object. Any ideas? Julian Hello, I was able to solve an issue I had in previous post in writing some code to grab a section of a cookie value string (2 letter state ex MD) and check against it to do something. That was easy because the state was at the end of the string and all I had to do was use the slice() method. Now I was to be able to grab the 2 letter state from a string that looks like this: BALTIMORE, MD|blah blah|blah blah|blah blah (the real cookie value string will always be separated with pipes (|)) Can anyone please help? Thanks in advance! Code: <HTML>

I could not figure out the answer, and could not find the answer from Google. I have following object PHP Code: ; var obj = function() { ; this.method_1 = function() { ; return this.method_2 } ; this.method_2 = function() { ; return 'my parameter' } } It works. If I want method_2 having parameter, I write it this way: PHP Code: ; var obj = function() { ; this.method_1 = function() { ; return this.method_2 } ; this.method_2 = function(para) { ; return para } } ; var newObj = new obj() ; window.alert(newObj.method_2('my parameter')) It works and returns "my parameter". If I want method_2's parameter to be assigned by method_1, I write it this way: PHP Code: ; var obj = function() { ; this.method_1 = function() { ; return this.method_2('my parameter') } ; this.method_2 = function(para) { ; return para } } It does not work. So, the question is how to assign a parameter of a method by another method? Thanks a lot. |
