3/4 So I'm new to AJAX and I have a few concerns. Let's say I include an iframe to a completely different website, say, one of the Yahoo or Google plugin (game, fortune) or something. Isn't it possible that we'll have variable name space collision between the different iframes? My understanding is all iframes and frame variables are shared but then again my understanding sucks. \_ Yes, this is a problem, though it's a smaller problem in practice, than you might expect. By and large, it's solved the same way that the problem of name space collisions in C code is `solved'. See: http://www.google.com/apis/gadgets/gs.html and search for __MODULE_ID__ for an example. There are actually some clever things you can do with scope in Javascript to more or less eliminate this problem. If you're playing around with Javascript, you might want to check out IGMonkey, a library I wrote to make it easier to do web mashups: http://www.csua.berkeley.edu/~dans/igmonkey It's largely targeted at the Google Gadgets API, and I haven't had time to work on it in months, but there's still some useful stuff in there. -dans |

2/9 Looking for a Javascript slider bar example. The first example on Google is horrible-- initialization code all over the place, global variables, method conventions suck, etc. Thanks! \_ I don't have an answer for you, but what do you think of this article? http://ajaxworldmagazine.com/read/333329_p.htm \_ From the article: "Although it's gotten significantly better with ECMAScript standardization, I would still rather program with Java than JavaScript, the main reason being inconsistency. Maybe in eight years the current version of ECMAScript will be standard across almost all browsers. But the current version of JavaScript, despite the random implementations, is already available, and there are zero installation issues. I think that's a fairly good proof that the reason Java hasn't taken over as the RIA language of choice is the installation problem." This doesn't lend much credence to the author's argumentation or critical reading skills. That said, I think it's an interesting read, particularly some of the resources it links to. -dans \_ Whoa, didn't realize the author was Bruce Eckel. I'll chalk the bad quote up to a goof as opposed to overarching incompetence. -dans \_ Christ dans, you're an asshole. \_ Yeah, but I stand behind my words. :) Though, it does beg the question, why does pointing out a flaw in someone's argument make me an asshole? Or is it because I believe flawed arguments are a sign of incompetence? Or is it because I excuse Bruce Eckel the occasional goof in light of a long history of insightful commentary? -dans \_ I think he's saying that Java is a better language but Javascript is easy to install. Since Javascript is where so much RIA action is, that suggests the installation difficulty as being very important. \_ Yes, I get what he's saying. He's just saying it badly. Also, having read the entire article, I think it would be more accurate to say he's saying that the available implementation(s) of the Java language are better than the available implementations of Javascript. Having written a fair amount of both, I feel that Javascript is a *far* better language. -dans \_ Really? I'd be curious to know why. (not disagreeing, genuinely curious) -emarkp \_ The short version: JavaScript is Lisp with Algol (for the non-language nerds reading this, C) syntax. A bit of elaboration on the short version: Lisp (and functional languages in general) have a lot of powerful tools (e.g. lambda/anonymous functions, closures) built in that many procedural languages lack out of the box. On top of that, Javascript is a *really small* language. There's something counterintuitive there, which is that, in my opinion, JavaScript, which is a much smaller language than Java (I mean the core language, not the libraries) somehow has line for line/operator for operator more expressive power. Note that I'm not bagging on Java because it's procedural; I love C. In general, I've come to the opinion that a small (but complete) language is a sign of good language design. -dans sign of good language design. -dans |

I plan to push some of my code back to prototype.js. prototype.js' map function is a crippled map that only takes a one argument function and one list. iGMonkey's map is a true generalized map that takes an n argument function and n lists. Don't get me wrong, I like prototype.js. Also, prototype.js' goal seems to be to make javascript work like ruby, which is fine, if that's what you want. Furthermore, prototype.js is monolithic, as far as I know, there's no way to pick and choose just the bits of functionality you want from it. I am working on a real #include function for javascript to make iGMonkey more component based. Hopefully the prototype.js folks will find this useful. -dans \_ That's it? That's your "I'm going to change the world" project? \_ I don't believe I said I was working on a world changing project. That said, most change is a gradual thing. Sure, if you're the leader of a major world power you can demolish a country on the other side of the world for shits and giggles (oh and because its leader was a bad man), and do it in days. Notably, the real change, i.e. the reconstruction effort usually takes longer.

But here we are 13 \_ You've already been written off as a kook. years later, and Linux has changed the world. To me, starting small is the only sensible way to single-handedly launch a project.

For instance i want to turn it on at http://bearlink.berkeley.edu but i want it off for <DEAD>www.microsoft.com;<DEAD> and i don't want to have to keep clicking on the preferences menu to do it. \_ No. Get Zone Alarm and do it that way. \_ Konqueror, the KDE browser is really good in this respect. It has a really clean interface that allows you to turn javascript on/off on a per site basis. As a bonus, it lets you do this with cookies too. Opera may do this, though I have not personally used it. I know both run under Linux, though I don't know what support is like on other unices. -dans \_ I agree with dans. |

8/7 Is there a way to add elements to a form with javascript? (eg, I click a button and a textbox appears.) Thanks. \_ You can use css to set textbox so it doesn't appear on the browser (couple ways to do this), and then use javascript to toggle. \_ yes, with DHTML. You do something like <SPAN ID="foo"></SPAN> and then dynamically set the contents of it to be whatever you want with document.all["foo"].innerHTML = "bar"; you will have some problems getting this to work across different browsers, though, since IE and Netscape have a different object model for all this DHTML stuff. \_ This won't work in Netscape for two reasons. As you point out document.all["foo"] (foo is an id) is IE specific code. On top of that, Netscape 4 (may be fixed in 6) won't reflow a page, so you can't dynamically modify the content of span/div elements. If you need cross-browser compatibility, I think your best bet is what the first poster suggested -- create all the elements you want statically and use css to toggle them visible/hidden. \_ if you really care about cross-browser compatibility, you wouldn't be doing anything dynamic in the first place. \_ Don't do it on a production page. It's bad from usability standpoint. |

5/14 In Acrobat 5.0 Javascript, how do you break out of an if statement in a particular mouse action? 'break' does not seem to work. Thx - jthoms \_ can't you restructure it so you don't need to do this? like a while loop around it or nested ifs? \_ Let me rephrase the question. Suppose I have a button-pressed event that has the following code in it: if (some_field < 0) { app.alert ("Please enter some_field that is >= 0"); <break>; } if (some_field2 < 0) { ... } What should <break> be? In VB, you can simply do an 'Exit Sub'. \_ if it's in a function or method or whatever, can you just use a return? \_ No, that's the thing, it's not really a function. It's an event. I did try 'return' and it says 'return undefined'. \_ I'm not familiar with Javascript in Acrobat, but how about something like: do { ... if (...) { break; } ... } while (false); Also, how about putting all your event code in a real function instead? have the event call the function, where you should then be able to use "return". where "return" should be valid. \_ does your stupid language not provide an else construct? if(cond1) { .. } else if(cond2) { ... } else if(cond3) { ... } \_ First of all it's not MY stupid language. Second of all, you're missing the point... I have no problem breaking out of an if statement; the problem is to break out of the entire event. Thx. \_ it would be easier if we better understood your problem. what do you mean break out of an event? how is that different from, say, having Foo() called in response to eventX, and then having Foo() return prematurely under your specified conditions? is there some other event handling code that will be run afterward that you want to avoid? are you trying to prevent subsequent events from being generated (like preventing a mouseup after a mousedown)? postprocessing you're trying to avoid? are you trying to prevent subsequent events from being generated (like preventing a mouseup after a mousedown)? |

10-04 is it possible to learn javascript without knowing java? if so, any recommended books? thanks. \_ Yes. Try JavaScript HandBook. BTW, javascript and java are not related, except that the both have the string java in them. \_ javascript syntax is loosly \_ ......? \_ JavaScript = LiveScript, or something equally dumb, originally. check http://irt.org first, then O'Reilly's 1000-pg. DHTML monster. \_ Aren't some of the JavaScript features implemented underneath with Java in the browser? This would shed some light onto Netscape's naming decision... and also why I get what seem like applet errors sometimes from what I'm pretty sure is Java*Script*. \_ AFAIR, the only thing that they share is the security stuff. |

7/12 dans startup got funded. \_ so was pixelon. so? \_ but we're much hipper and sexier than they are. \_ cool. is he looking for a ceo? \_ ksinger is the ceo. \_ http://www.adjectivity.com - apparently they're doing cell phone shit, too. \_ infoP(lease) \_ http://www.adjectivity.com - \_ From the Web site: "They believed that consumer software, long been (sic) a hostage of computer scientists, needed to be designed by consumers themselves. Setting a course that would eventually lead to the creation of Project Voyager, the founders formed Adjectivity Corporation to guide the project to market." So what are they saying? That they invented the focus group and user testing as part of their heroic drive to PROJECT VOYAGER? Or that software *really* needs to be written by Joe Six-Pack using Javascript or Visual Basic for Word (languages for the "common man"), rather than by crusty old bald guys like bh, hacking away with Common Lisp in their ivory towers? \_ i think it mean that computers aren't for just a bunch of lame ass, 4 eyed, nerds anymore. \_ Like that'll ever happen when most people have trouble with the TV remote or the 2x/4x switch in their SUV. \_ when is it going to IPO? \_ Donate stock to the csua! -John \_ It will be a good tax-writeoff for the csua |

2/26 Help, someone keeps subscribing me to mailing lists. It is overly easy to sign someone up on these web mailing lists. How do I keep from getting these mailing lists? Thanks. \_ Maybe someone as a personal vendeta against you. Have you made enemies with anyone recently? I'm not sure how possible this is but I've heard web browsers being able to transmit certain information stored on your machine via javascript or cookies or something like that (don't know much about it myself). My advice is that if the mail comes from a legit source email them back asking them not to mail you anything anymore. But usually it's illegit spam mail in which case you should complain to that person's ISP's postmaster or just ignore it. |

8/11 Is there a way to check to see a certain function is defined in JavaScript? Thanks. \_ If hasClue($programmer) return true else useRealLanguage(); \_ Personally, I find embedding "Real" languages into HTML just the type of invaluble experiment in futility that one would expect suggested from JUST ANOTHER ASSHOLE LOSER PREACHING HIS IMPOTENT CASE BECAUSE IT MAKES HIM FEEL LIKE A BIG MAN TO WAVE AROUND HIS ROMANTIC SENSE OF HIS OWN INTELLIGENCE IN OVERCOMPENSATION OF HIS OWN PATHETIC TINY NEEDLEDICK. - my name is (fucker) \_ fucker, will you marry me? \_ You're too late. Get in line. -(fucker) \_ Cool. Caught you. --trolling for flames \_ The question was not asking for an alternative. If you don't know the answer, why bother posting? \_ Exactly. You don't know the answer so why bother posting? |
