Once Set A Private Variable, Test That Object Independently Becomes A Nightmare As The Next Test Is Polluted By The Actions Of The Previous?
Mar 14, 2009
I'm using the standard module pattern and the problem is once you set a private variable, trying to test that object independently becomes a nightmare as the next test is polluted by the actions of the previous.So, the options are to have some reset method (which is horrible), setters on everything (defeats the point) or delete object and re-load script (hideous).

I am using Javascript to add rows to tables, etc. in a function I am
calling. I pass the function the ID of the div, and what I want in the
rows, and it will add rows to a table in the div.
The problem is I need to test for the existence of the table - and if
the variable or object doesn't exist already my code errors -
PLEASE REMEMBER - I don't know the name of the variable or object I am
testing the existance for - it is created dynamically based on the
divID. So when I test for this object or variable the test has to be
for a dynamically created object - Code:

Is it possible to test whether two objects are equal using the data they contain inside and not comparing their pointers with ==?
Well actually of course there is but...
Is there a way to do it without actually looping through the object, instead maybe something that came with JS? (something like a .equals() method from other programming languages.)

I have the following code that test the target element of a mouse
movement to check if its and Image and the Parent is a Div element. It
works perfect in Fire Fox, however IE does not allow access to test the
target against instance of HTMLImageElement or the Div Element.
Is there a property that I can use to get the object type that will
return "image" or "div" or anthing else that I can use. The typeof
function only returns "object" which is totally useless in my
application.
DragObject.prototype.mouseMove = function(ev){
ev = ev || window.event;
var target = ev.target || ev.srcElement;
var dragObj = target.getAttribute('DragObj');
if ( target instanceof HTMLImageElement && target.parentNode
instanceof HTMLDivElement){
target = target.parentNode;
dragObj = target.getAttribute('DragObj');
}
}

I have a form on a page that the user fills out. When he's done and it's validated, I need the contents along with some other stuff to be printed before it's sent to the server. To accomplish this I'm using window.open on the Print button, then I intend to reference the fields from the page which opened it using the window.opener.formname.fieldname.value .
Problem is I have couple sets of radio buttons on the form that was filled out and I would like to print all the radio buttons showing the selected one so that the user acknowledges on the hard copy what his choices were.
If I was doing it server-side(ASP), I'd test the value of the incoming form value by executing a function, and I'd like to do it that way too, but I can't seem to figure out how to do that without putting <SCR IPT>function...</SCR IPT> tags with every radio button <INP UT> tag.
This also applies to where I'd like to write the values as HTML.

Is there a way to test for security settings in a users browser AND
their firewall. Lets say someone is using zonealarm. Is there a way
to test for their setting in zonealarm, so I can then redirect them to
a specific page.
The reason I am asking is that I have a flash front page. A user
cannot see the page because he has his security settings set so that he
does not see activex controls. I want to be able to test for those
settings then redirect him to a static page.

I want to supply a button on my public web page if I have opened up my
private web page, but disable it or remove it if the private page is shut
down. Is this possible?
In other words, I often have a port open for a chat page and I use
no-ip.com to do a port redirect. When the port is open, I want my public
page to test the port when a user loads the page, and if the port is
available, supply a button to click over to it.

When looping thru a group of elements and using getNamedItem('itemname').value there are some elements that are going to have a null value for that particular getNamedItem... the problem is that you cannot test this value to see if it's null because it generates an error instead, and the code does not continue: _allnames[_j].attributes.getNamedItem("onchange") is null
You cannot even test it for null like this: if (_allnames[_j].attributes.getNamedItem("onchange").value != null) { do something } This will also generate an Error instead of testing to see if it is null.
How do you test getNamedItem for null to avoid this error?
EDIT: It appears that the problem is limited to Firefox. It works fine in IE7, but the error occurs in both FF v3.5.4 and in v3.5.5!
In my example below, there are no elements that match, so you should see an alert box that says 'No match', but (using Firebug) you will see that an error is generated when it tries to find the value of onchange in the last input tag.

I am doing an image/data rotating script. I get the data from a XML. I parse that data and build the divs and such.Data Set 1 --- background image in a div, with a button and some text overlayed on the div.
...
...
Data Set 4 -- etc..The thing is, I load the script and the div appears, BUT the text overlay appears first THEN the image pops up for the first Data Set. I can't have that. I need them both to appear at once.Is there a way to determine that a div background image is loaded?-- I have access to the prototype js library.

Say I have two sets of radio buttons. One is group name "location" and the other is group name "time".
Lets say location has 4 possible values and time has 2 possible values.
All location values should be both time values as a possibility except the last location value which should only be able to select 1 of the 2 time values.
How can I popup an error message if location has a certain value and time has a certain value.
I really don't know the operators to use. Please give sample code with operators if you can.
I don't know if there is such a thing as a if then radio selection or not but I figured javascript could do it instead.

I coudn't understand some behavior of RegExp.test function.
Example html code:
----------------
<html><head></head><body><script type="text/javascript">
var r = /^https?:///g;
document.write( [
r.test('http://a'),
r.test('http://b'),
r.test('http://c'),
r.test('http://d')
]);
</script></body></html>
---------------------
The page displays true, false, true, false. (in Opera, Firefox and IE)
This is strange because I expected it would display true, true, true,
true. There must be something I didn't know about the function
RegExp.test.

My popup code doesn't appear to work with Internet Explorer 7 and before I
spend time bug hunting I would appreciate it if a few IE7 users could visit
my site and confirm if the code doesn't work for them too.
Visit www.microbuild.com and in the top right hand corner you will see three
buttons for Online Support, Email Us and Call Us. Just click any one of
those three buttons then let me know if the popup was successfully opened
using Internet Explorer 7.
