Setting A Property That Has Only A Getter
Jan 2, 2011
The code works as expected in Chrome, but not in IE and FF. In IE the error is "Object doesn't support this action" and in FF "setting a property that has only a getter". In Chrome there is no error in the console. There are three javascript <script>...</script>s that exist to display a <td> row in a table with a particular graphic depending on the screen width. The odd thing is that in both IE and FF (and of course Chrome), the first two scripts display perfectly well. Why does the third <script> produce an error? It has exactly the same form as the two before it.
I can only guess it has something to do with where it occurs :confused: Googling the FF error, it has something to do with trying to set a read-only property, but then why do the first two <scripts> work? They are no different (at least I can't see a difference.)

Is there a way to access the value assigned to onmousedown for an
object? I've been searching online but can only seem to find how it is
assigned via html. What I need to do is access the value (the script
string) in javascript.
For example, I'd like to try to do something like this:
function virtualClick(objectName) {
eval(document.getElementById(objectName).onmousedo wn);
}
I am of course not explaining the full problem in detail, but would
appreciate any input on how to access the onmousedown value (or to know
if it even exists as a property).

Trying to add a new property to a non-jQuery object from inside each loop doesn't appear to work:
var arguments=new Object();
arguments['ticket']=ticket;
arguments['email']=email;
arguments['module']=module;
arguments['epoch']=new Date().getTime();
var total=0;
$('select.category').each(function(){
var name=$(this).attr('id');
var option=$(this).find('option:selected').val();
total+=parseInt(option);
arguments[name]=option;
});
The 'total' variable works as expected. The the 'arguments' variable doesn't. Almost like
a variable scope issue or something. If I put some extra debug code to print out all the
property/value pairs, outside each loop I only see original four, and inside each loop only
the new one just set and none of the original four.?

I am currently encountering a problem with setting "display" property from "none" to "block":
Browsers will refresh itself when the display property is changed; this causes the element to display then suddenly disappear after the page reload. Do you guys have an idea what I can do to avoid it?
I tried using jquery's show command, css command with setting display to block, and pure javascript method like document.getElementById("theId").style.display="block".

What happens if you do this?
function Person() {}
Person.prototype = 7;
var ted = new Person();
Also what happens if you set Person.prototype to an array or function?

I'm sending arrays of results from my server in response to an xmlhttprequest like so:
array({key:value[,...]}[,...]);
I know I could use an associative or indexed array, but this is just how I wrote it as I'm using the prototype library and I'm in the habit. Anyway, I want to know if I can reference 'key'. If so, umm, how?

I'm using javascript to dynamically make controls show up or disappear on a form. For some reason, if I load a control (in this case a select control) into the Div it shows up perfectly. If I load text in there, it is fine too. However, if I programmatically try to go from the select control content and cover it with text afterwards, that won't work.
If I change the content from one string to another, it works as well. I just cannot remove a control I've put down and replace it with text or "" or whatever.

I just wrote this script which loops through all of the CSS properties for an element, and dynamically generates an HTML document using a for/in loop in a new window which is a table of all CSS properties and values for the element. Some may find it useful.
You can see the demo here:

({}["toString"]) - function
alert("toString" in {}) - true
But I want to only find a property that is defined in the object - not in a prototype.
for(var prop in {}) { alert(prop); }; // toString not found.
It seems that operator 'in' is overloaded. 'in' during iteration: look in the property. 'in' in a boolean conditional: look in the object, then up the prototype chain.
I want a way to get only properties defined within the object itself, not it's prototype. Is there no simple way?

support 'disabled' for form elements for example something like
<INPUT class=f2 type=checkbox value="C" name="chkAttr" DISABLED />
is not working for netscape whereas its working fine for IE.

I would like to override the "disabled" property of a hidden field. When
disabled is set to "true", it would call a function to disable 2 other text
fields on the form. When disabled is set to "false", it would enable those
2 text fields. You should also be able to get the value of it as if it were
a property:
alert(my_hidden_field.disabled);
Is there any way to do this?

Is there a way to determine the object that a property is in? For
example:
function MyClass() { ... }
MyClass.prototype.myFunc = function() { ... }
var obj = new MyClass();
var sameobj = SOMEFUNCTION(obj.myFunc);
So my goal is to get a reference to the object by just having the
property.

I have a script that I want to run only when my input box IS NOT
disabled. Can someone tell me if something is wrong with my script? Is
"disabled" the correct property to use?
function TextChanged(i){
if (!document.ScheduleForm["txtGrossPayroll" + i].disabled) {
document.ScheduleForm.txtRecordStatus.value = "Changes Made; Record Not
Saved.";
document.ScheduleForm.txtRecordStatus.style.color = "#FF0000";
}}

I've code like this:
var x =window.open('http://localhost/canvas.html','myokno')
var w =x.width
Permission denied to get property Window.width
var w =x.innerWidth
Permission denied to get property Window.innerWidth
why i can get properties of new created window???
The second problem is much more important:
i want to get element which id is "canvas" and it is in new window so i do
like this:
var canvas = myokno.document.getElementById('canvas')
ReferenceError: myokno is not defined
var canvas = x.document.getElementById('canvas')
Permission denied to call method HTMLDocument.getElementById
so i start working on the problem and:
var can = x.document
can
[object HTMLDocument]
var can2 = can.getElementById('canvas')
Permission denied to call method HTMLDocument.getElementById
what i doing wrong?

I am writing a Javascript UI component. I have already written a
"disable()" method for it, but I would like to go one step further in
order to make my component as compatible with existing HTML controls as
possible.
With standard HTML controls we can do this:
myTextField.disabled = true;
and as soon as this property is set, I assume there is a property
listener of some kind that is invoked to change the appearance and
value etc of the control.
I want to write my own 'property listener' to do this with my control.
Can I do it in Javascript or is this too "low level", requiring code at
the browser implementation level?

To stop the keyboard event for the F4-key from propagating in IE I need
to set event.keyCode to 0. But setting keyCode to 0 in Mozilla/Firefox
will throw an exception since it is a read-only property.
So, how do I check if event.keyCode is writable?
(I could do some check to see if the script is run in IE or add a
try/catch for Mozilla, but I would like to know the 'correct' method)

Is there a way to make one property an alias for another? This would
mean that if the value of the original is changed then so is the value
of the alias. I tried the following example and it does not give this

Some of the object properties in the Dojo Toolkit are set to objects but they are using syntax like this:
object.property = new function() {
this.property = someValue;
this.property = someFunction;
}
Is the property set to a new object and if so what is the "new function()" statment doing?

I have developed a script that change the font size in css, but only
the attribute "font-size" on the body tag, not change the entire
active stylesheet.
When i click to change the size
<a href="#" title="Change Font Size"
onclick="cambia_font_size(2);">A</a>
It works fine, but when i try to check the cookie to set the default
font size, it does not work.
The cookie stores the value correctly and i can read the value. The
problem is when i try to change the value:
document.getElementsByTagName("body")[0].style.fontSize=tam;
I have tried also writing this code at the end of the html document
but it doesnt work
<script type="text/javascript">inicializa_fontsize();</script>
What could happen? Code:

I'm using ccs3PIE with my site. What I want to do is check if a DOM element has a css property like border-radius and then add a class to it.
The problem I'm having is that I don't know how to check for the css property. I've been searching for it for a couple of hours now and I can't find anything that seems to work.

I have a JS script that presents a series of "pages" with different questions inside a single HTML file, by rewriting certain <div>s. I have an object like this that contains the questions and information about answer labels etc (the idea is that this should be easy to modify for someone who doesn't know JS):
