I'm trying to connect a browser and another program using JavaScript. I would like to send instance names from a browser to another program for callback method.
Why when I try to access a variable that don't exist, javascript throw an exception but when I try to access a property that don't exist in an object, javascript returns an undefined object?
For example, this case returns an undefined object:
function Foo(){
console.log(this.bar);
}
Foo();
But, in this other example, javascript throw an exception:
function Foo(){
console.log(bar);
}
Foo();
ReferenceError: bar is not defined

Basically I just can a icon that they can press which will flip the value of a boolean in the broadcast receiver, and change the icon to indicate something happened. I think I need to do something with a widget? Could anyone point me in the direction of some tutorial I could check out?

I have some pages indexed by Google, for example:
/product.html?affiliateid=142
I want a rewrite rule to 301 redirect to the same page if there's an affiliateid=xxx

How can I pass a variable from JSF managed bean to JSP page.
PS: I'm in portal context (liferay).
I tried this:
in Managed Bean:
HttpServletRequest request = (HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();
request.setAttribute("var", "someTxt");
in JSP:
<%
String var = (String)request.getAttribute("var");
%>
I don't get any result.
i got a code of 100-200 rules for making a table. but the whole time is happening the same.
i got a variable $xm3, then i make a column . next row, i got $xm2 and make column. next row, i got $xm1 and make column.
so my variables are going to $xm3, $xm2, $xm1, $xm0, $xp1, $xp2, $xp3.
is there a way to make a forloop so i can fill $xm and after that a value from the for loop?

I'm uploading images in a grails app I'm developing and I want to be able to have an environment variable the determines where these images are. So if I'm working locally it can just pull from /home/MyName/images but once it's in production it will pull from http://images.site.com. How would I do that? I'm assuming i can set up my config.groovy with the variables i'm just not sure how i switch between them or use them in code.
I am new to Xcode. I am not sure if there is a way to view a variable's references just like "Find all references" in Visual Studio by right click on a var?

@interface MyInterface {
...
BOOL isSet; // view all references to this var?
...
}
I have an ID in a package variable that I need to add as a column (with each row having that package variablevalue) in a Dataflow.
Is there a way to do this with only the Derived Column? I know i can using the Derived Column to make a new column and then set the value using a Script Component, but that seems inefficient.

I've been following Ryan Bates' Railscasts tutorial on CarrierWave, which you can find here
Everything works fine, except for when I go to view my profile, it gives me this error:
undefined local variable or method `user'
I don't know why it is telling me this, as I am using Devise for my authentication, and that is the name of my model.
Below are some of the files which may be useful:

I have a set of observations of the form "Country GDP Year". I want to create a new variable GDP1960, which gives the GDP in 1960 of each country for each year:
USA $100m 1960 USA $100m 1960 $100m
USA $200m 1965 --> USA $200m 1965 $100m
Canada $60m 1960 Canada $60m 1960 $60m
What's the right syntax to make this happen? (I assume egen is involved in some mysterious way)
