I'm creating a function to show/hide a menu when clicking an anchor. I want to determine the effect it uses by passing it in as a variable but it no likey!

I am sending a url request to the network using jquery.get(). The problem I am facing is that the server is having an http authentication, so when i pass the request url directly on the browser, it will show the authentication window and i can pass the username and password, but what to do when i am passing the same request using get() method.
This is what i am using currently
Anybody knows a work around for this problem, which can be used for every browser. the current error code is 401..

I have two methods and I would like to call somename1 method from within somename2 method. I have tried several ways to do so however I keep getting "TypeError" or "RefernceError" I have tried several ways to reference but I am still unable. What am I doing wrong. I would think this would be easy to do.
I'm trying to do something, but I don't know if it's possible. Basically, I want to have a public static class method that could access a private object's method. I would like to be able to do :
Class.method(InstanceOfClass);
The method would then access a private function from Class by doing something like
function method(param) { param.privateMethodOfClass(); }
I've done a lot research and experimentations but just can't come up with a solution... I don't even know if what I'm trying to do is possible.
Why is the callwhy is the slice method only a method of an Array instance? The reason why I ask is because if you want to use it for the arguments property of function object, or a string, or an object, or a number instance, you are forced to use Array .prototype slice.call(). And by doing that, you can pass in any type of object instance (Array, Number, String, Object) into it. So why not just default it as a method of all object instances built into the language?In other words, instead of doing this:
function Core(){ var obj = {a : 'a', b : 'b'}; var num = 1;[code]....
//right now none of the above would work but it's more convenient than using the call alternative.
} Core('dom','event','ajax');
Why did the designers of the javascript scripting language make this decision?
Is the form below a valid method of changing the id of an XHTML element, specifically the one actually being referenced? It does not seem to work for me.
I have been trying to grasp the whole 'Pass By Value/Reference' thing for a few hours now. From what i can make out:
Passing by value will make a copy of the value, pass it as a function argument and the function will store the changes, the original value is not affected. So for example:
JavaScript Code: var cost = 145;var postage = .3;var a = function() {return cost + postage;} //Using an Anonymous function for this
If you was then to pass the value of 'a' to a function argument it would copy and not change the original value.
If you pass by reference it will change the original value. When you pass a reference to a value through a series of different functions and the value is constantly being changed the change happens on the original value and can be seen outside the function.
The problem is i cannot think of how or why this would be used. I havn't got to develop many large applications so im trying to think of a few situations when passing by reference would be used.
I am loading Jquery tab using Ajax. The loaded tab contains a button for saving data. When i Load the tab more than one , the method for save is executing(triggering) more than one.
I could not run the .submit method. See the code below:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html> <head> <title>My Test Page</title>
I attempted to invoke a C# method using jQuery but it failed. The reason is because the method cannot be found. However the method exist in the class. Did I miss something?
The above code works fine at Firefox and Google Chrome. And it works at IE 8 for the first drop action. The ajax method is not called after the first call although the append still works.
