Hi. I need a small function for jQuery that would close multiple DIV elements, but I'm having trouble with JS syntax. I got this far: function closePanels{ $("#servicesPanel").hide("fast"); $("#portfolioPanel").hide("fast"); $("#contactPanel").hide("fast"); $("#aboutPanel").hide("fast"); }; Sounds logical to me: That...
Any good utilities out there for verifying VBScript syntax without actually running the script? What I'm getting at is if I do something like: If (year == "2005" && type == 1) Then ... End If Is there a tool that will tell me that the '&&' really should be 'And' and the '==', just '='? ...
Hi, in VB.NET it is possible to omit parentheses when you call a parameterless function. However this can be very confusing because developers could think that a statement is accessing a property instead of a method. this could result in a performance drop if you are calling the method again and again instead of storing the result in a ...
Is there any "short" syntax for creating a struct in ColdFusion? I'd like to replace this verbose code: <cfscript> ref = StructNew(); ref.Template = "Label"; ref.Language = "en"; stcML = GetPrompts(ref); </cfscript> with something more like a JavaScript object: <cfscript> stcML = GetPrompts({ Template: "Label", Language: "...
When writing the following today in C# DateTime.Now.AddYears(-60) I wondered whether there are any languages that allow a more natural syntax with units: DateTime.Now - 60years Does anyone know of any? Specifically, I'm interested in the presence of unit operators(?) that turn "60years" into e.g. "TimeSpan.FromYears(60)". It'd also...

Just now I needed to do something like the following query, and was surprised that it actually worked as intented. However I cannot find any documentation on it so I'm a little afraid about unknown side effects of this. Here's what I wrote: select * from Table1 where (col1, col2) in (select col3, col4 from Table2) This seems to be mat...
var foo = { "bar": {"blah": 9 } }; Is there a way to get the ["blah"] value of the only member of foo if I don't know the key is "bar"? Can I somehow reference the first member of an object without knowing its key? I'm looking for the equivalent of foo[0]["blah"] if foo were a normal array. In my case, I can't practically iterate...

Why do most languages seem to only exhibit fairly basic control structures from a logic point of view? Stuff like If ... then, Else..., loops, For each, switch statement, etc. The standard list seems fairly basic from a logic point of view. Why is there not much more in the way of logic syntactical sugar? Perhaps something like a propos...

Recently I ran some of my javascript code through Crockford's JSLint, and it gave the following error: Problem at line 1 character 1: Missing "use strict" statement. Doing some searching, I realized that some people add "use strict"; into their javascript code. And once I added the statement, the error stopped appearing. Unfort...
Hey, I'm new to Rails and Ruby in general. I was wondering if it's possible to use an embedded ruby css file (css.erb), similar to using html.erb files for views. For example, I'm using <%= stylesheet_link_tag "main" %> to link to my main.css file in public/stylesheets, but when I change the file extension from main.css to main.css.e...
