Hello everyone ! Thomas asked me to discuss here the behavior of Element.addClassName, as relating to ticker #2232 [1]. In HEAD, if the element passed-in to Element.addClassName does not exist, an exception is thrown, and script execution stops there. I believe this is inconsistent with other functions: Object.extend(Element, { hasClassName: function(element, className) { element =

I'm writing some code that does a bit of introspection of R6 classes and am wondering about the "classname" parameter. Its the first parameter to the "R6Class" class generator generator function, and the few examples I've looked at on CRAN set it the same as the name of the generator function, for example, from the docs: Queue <- R6Class("Queue", .....)

Hi, I have just started using prototype.js and scriptaculous.js in one of my projects. These libraries are awesome and they let me do so much more, so easily. At some point in my web interface, I have an element with multiple classes, out of which one class needs to be removed. I am using Element.removeClassName(element, "classname to remove"); to achieve this. This call does remove

How should I expect the performance of this function to be? I wrote this code: function CreateTOC(){ var $aTOC = document.getElementsByClassName(''tocitem''); if(isArray($aTOC)){ $temp = ''<INPUT TYPE="SUBMIT" NAME="cmdSave_Update" VALUE="Close" CLASS="menubuttons"> ''; $temp += ''<INPUT

I have a situation where I need to get the first class name of an element. Element.ClassNames() returns an object not an array... Object.values() will turn it into an array, but the API Docs say that the order of the resulting array is browser-dependent.. So for my use is no good... So I am using: el.className.split(" ").first(); Can any one see any problems that I might e...

Hello, I noticed (due to a recent post by Martin Honnen to clp) that Element.Class uses wrong regexps for its operations. E.g., Element.Class.has() will find "classA" in "classA-foobar" I also changed the interface of .has() to the more general one used in .has_any() --- util.js.old 2005-08-21 19:18:40.000000000 +0200 +++ util.js 2005-08-21 19:31:42.000000000 +0200 @@

Hi, in 'Writing R Extensions" of R v2.10.0, under Section 'Cross-references' (2009-09-07) it says: 1. "The markup \link{foo} (usually in the combination \code{\link{foo}}) produces a hyperlink to the help for foo. Here foo is a topic, that is the argument of \alias markup in another Rd file (possibly in another package)." 2. "You can specify a link to a different

I''m trying to update a list, and having a hard time applying visual effects to the latest element created. Here is what I''m doing. =========================================== 1) Creating an "item" via an action, then rendering the RJS template 2) RJS template looks like this: page.insert_html :top, ''items'', :partial =>

<input type="text" name="date1" id="dateField1" onchange="magicDate(''dateField1'');" onfocus="if (this.className != ''error'') this.select()" /> How could I generate above text filed using ruby? I am not sure how to give the options such as onchange, onfocus, id and so on? could some one please help. --

Hi all, I have a property, defined in an external stylesheet: .my_class { background-color: #FF0000; } I want to retrieve the value of this background-color of the class my_class. How can I do that with prototype/scriptaculous ? Thanks in advance, Nicolas Terray

I don''t know why, but I am drawing a complete blank on something that should be easy. I''ve been searching, perhaps using wrong terms, and still not coming up with anything. Here''s what I''m trying to do: <div class="button" onMouseOver=''this.className="button_hover"''; onMouseOut

Hi all, The latetest trunk revision 1983 features are more streamlined directory layout and a new util.js file, that acts as a collector for stuff that doesn''t fit in elsewhere. To get a grip at the new Builder functionality look at the test in test/unit/builder_test.html (works only with Firefox). Note the "klass" instead of "class", this circumvents a

Here''s what I''m trying to do. I have two divs, one holds about 20 small images of products and the other holds a single large image of one of the products. I''m trying to use the jazzy "new Effect." way of changing images but I can''t seem to get it too work. My script is replacing the image and then making the element disappear. What

Hi Guys, What''s the best way to grab all <td>''s in a particular table and manipulate them? Here''s the problem definition - I have a table that has ''n'' <tr>''s. Each <tr> has couple of <td>''s and the first <td> has an image. By default, each <td> has a ''x'' class and image src

While $$ and getElementsByClassName are ridiculously speedy in Firefox (thanks to XPath), I''m finding both functions to be intolerably slow in IE. The page I''m working with has fewer than 1000 elements -- doesn''t seem THAT big -- and it''s still taking upwards of 4 seconds (!) to pick out the right ones. Are there documented problems with particular

Hi I''ve tried to use Prototype as a base for few large intranet applications I''m working on. Unfortunately I encountered some serious performance problems when working with Internet Explorer. It''s really sluggish when it comes to DOM operations and Prototype could really benefit from some small optimizations. I created a testase to show a difference between my optimized
