• Arguments.length In Javascript Depends On Invocation Arguments, Not Function Signatures

  Posted on Mar 24, 2011 at 10:23 AM

  If you do want to know the number of arguments that are defined for a function, so that for example you can compare what you were expecting to what you actually get, you can use something similar to the following: function fnGreat(arg1, arg2, arg3){ console.log(fnGreat.length == argume... read more »

• Finding The XPath Of A Given XML Node In A ColdFusion XML Document

  Posted on Nov 2, 2010 at 12:12 PM

  Not quite the same thing, but if you have the XML file locally, or have it on the same domain (due to same domain JavaScript restrictions), you can use the Spry Data Set Explorer to load an XML document and then navigate within the structure of the document to see what the XPath would be for the... read more »

• Using Composed Javascript UI Controllers With Event Delegation

  Posted on Oct 14, 2010 at 4:54 PM

  @Ben, Good point about the constructor creating all of the list items controllers when itself is created, so agree probably better to have it as a construction parameter. I suppose that the setter for the item controller could be useful if you want to replace the controller on the fly... read more »

• Using Composed Javascript UI Controllers With Event Delegation

  Posted on Oct 14, 2010 at 4:01 PM

  Ben, As I've read through the last couple of post about the UI controls, one thought that I had was that the ListController has a dependency on the ListItemController class/object. Perhaps the ListItemController could be a parameter of the ListController constructor, or settable via a metho... read more »

• Javascript Array Methods: Unshift(), Shift(), Push(), And Pop()

  Posted on Jan 20, 2010 at 3:20 PM

  @someone else, I had a sneaky suspicion that call or apply would be part of the solution I was looking for. Thanks for posting the snippet, I'll be saving that one for sure.... read more »

• Javascript Array Methods: Unshift(), Shift(), Push(), And Pop()

  Posted on Dec 29, 2009 at 4:26 PM

  Ben, The array method that I've been using a lot of lately that I don't see many people use is the splice() method. It allows removal (and optionally insertion ) of items at an arbitrary index in the array. It will return an array of elements removed from the array: // Example 1... read more »

• Ask Ben: Selecting Random Values Without Repetition In ColdFusion

  Posted on Feb 3, 2009 at 5:15 PM

  Ben, This code has the potential to run, especially if the length of the list and the number of items to pull are fairly close to each other. Imaging 1000 numbers and pulling 990 out. The random number generator may pick many times in a row already picked items. Of course for relative... read more »

• Kinky Solutions Shop - Holiday Season Beta Launch

  Posted on Dec 19, 2008 at 11:01 AM

  Creating yet another account and trying to keep track of it isn't what a lot of folks will want to do. How about using OpenID ( http://openid.net/ ) as a user authentication method? The bonus here would be if you haven't implemented OpenID before,... read more »

• National Regular Expression Day And Reflections On My Own Journey

  Posted on May 30, 2008 at 1:13 PM

  As /s are used in a number of languages as indicators of a regular expression object, perhaps the /'s in your poster should be around the date rather than in the middle of it.... read more »

• Compiling Several Linked Files Into One File

  Posted on Apr 8, 2008 at 9:50 AM

  @Ben, One concern I'd have with this implementation would be that you can run into caching issues. For example, you're combining 3 JavaScript files into one file without a "build number" in the file name. If you change one of your source JavaScript files, and rebuild the combined file, then... read more »

• CreateGradient() / DrawGradientRect() Added To ImageUtils.cfc

  Posted on Feb 20, 2008 at 11:08 AM

  Ben, My initial thought was that you could pass the DrawGradientRect a Gradient struct with the properties that are needed by CreateGradient DrawGradientRect, but then I was also thinking about the calculated set of color values that could then be used multiple times. As I've not looked at... read more »

• CreateGradient() / DrawGradientRect() Added To ImageUtils.cfc

  Posted on Feb 20, 2008 at 9:36 AM

  Hey Ben, Was there a particular reason that you have the "passthrough" parameters for DrawGradientRect in a different order than they are in CreateGradient? It seems to me to make the order of parameters the same would make them easier to remember (as well as potentially copy and paste when... read more »

• DreamWeaver CS3 Slows Me Down

  Posted on Feb 19, 2008 at 11:26 AM

  It would be good if Dreamweaver had such a code editing feature as what I would call "smart snippets" that are used in Eclipse. IT tends to be a bit more visual focused, a feature that could be considered similar would be the Server Behaviors where a UI can pop up where you enter the parameter va... read more »

  Posted on Feb 18, 2008 at 10:03 PM

  @Ricky, Just to be clear I do not work for Adobe, I'm part of the Community Experts program: http://www.adobe.com/communities/experts/ If you have any suggestions about features for Dreamweaver make sure to s... read more »

• DreamWeaver CS3 Slows Me Down

  Posted on Feb 18, 2008 at 4:53 PM

  @Ben, Every application I recall using CTRL+Z is undo, and CTRL+Y is always redo. So for me if it deleted a line each time, I'd be in trouble. For me, CTRL + page up/down does (as well as without the CTRL held) moves the cursor to the top/bottom of the presently viewed "page" of code... read more »

• DreamWeaver CS3 Slows Me Down

  Posted on Feb 18, 2008 at 8:57 AM

  Hey Ben, I'm an Adobe Community Expert with a focus on Dreamweaver so I may be slightly biased in my opinion. :-) First off, no capital W in Dreamweaver. Regarding your comment about a networked drive, yes in fact, Dreamweaver is likely trying to refresh the files list every tim... read more »

• RELoop ColdFusion Custom Tag Case Study

  Posted on Nov 14, 2007 at 9:07 PM

  @Ben, Thanks for the link. I was also thinking about the different escape chars for different languages/context, puls what happens when you combine the two, like a CF string with escaped string that has an embedded JavaScript code sample. The mind just goes a little wonky. Thanks for... read more »

• RELoop ColdFusion Custom Tag Case Study

  Posted on Nov 14, 2007 at 11:27 AM

  Hey Ben, Haven't played with your solution to test it, but it appears that you're not taking into account escaped quotes within a quoted string, so for something like the following string: She said: "If you want to quote something add a "" symbol to start of \r\n the string,\r\n<... read more »

• Javascript Number.toFixed() Method

  Posted on Oct 29, 2007 at 7:01 PM

  @Ben, Yes, Number(str) will be NaN if the value of str isn't converted into a number. Make sure that you use isNan() to check for values being NaN because NaN does not equal NaN. var str = 's1234.56789'; var n1 = Number(str); var n2 = Number(str); alert(n1 == n2); <... read more »

• Javascript Number.toFixed() Method

  Posted on Oct 29, 2007 at 9:56 AM

  There are several ways to convert strings to numbers in JavaScript. One way is the parseFloat that you've shown here, but you can convert it directly into a number with the following: var str = Number('1234.56789'); An alternate method of moving a string to number is to subtract 0 from... read more »
