Message from The Natural Philosopher Most recent post: 10/28/2007 8 authors and 30 replies. Another extremely weird feature from iE6 I have a site, whose predominant colors are green background with white writing. There is a style sheet with many styles, of which all either specify a green background, or do not specify any. Body defaults to green. At the customer site, some <INPUT type="TEXT"> elements showed up with a white background on one machine running IE6. I did not have a chance to investigate further. Highlighting the white on white entered text showed it was there, just invisible Further madness occurred when on this machine a form containing about 10 of such inputs, that as far as I know were identical HTML, showed up with some white and some green background. My own test machine running AFAICT the same IE6 version doesn't display this problem. Her is a code snippet that gave some fields white, some green:-<TABLE width=90% border="0"> <TR><TD align="right">Name:</td><TD align="left"><INPUT type="text" maxlength="32"name ="name" value=""></td> <TD align="right">Phone:</TD><TD align="left"><INPUT type="text" name= "phone" maxlength="32" value=""></td> </TR><TR> <TD align="right">Address 1:</td><TD align="left"><INPUT type="text" name="address1" maxlength="30" value="" read more about Possibly OT.

Message from dunerunner Most recent post: 10/28/2007 2 authors and 4 replies. We've a table within a div whose overflow-x is scroll. It is a long table, so the width of the div is 800px, giving us a scrollbar at the bottom. When users tab from cell to cell, the cells that contain select elements that were out of the visible viewing area acquire the focus, but they are still visually off the scrolling region. So, the user has to manually move the scrollbar to bring the element into view. Is there a way we can manipulate the scrollbar (or whatever) to move that entire element into view?Thanks, Tim read more about Scrolling a div

If the user answers NO, they remain on the page.

Message from Brian Adkins Most recent post: 10/28/2007 7 authors and 67 replies. I'd appreciate recommendations for JAVAScript code that implements drop-down, hierarchical menus. Are there high quality libraries for this, or is it more typical for people to roll their own? My preference is for open source code, but royalty-free commercial code'd be acceptable as well. Ideally, the code'd: * Allow configuring horizontal or vertical menus * Allow configuring the delay for closing the menu after mousing out of the menu * Provide a mechanism for playing well with existing code and other libraries * Be well designed & documented * Be highly portable among browsers in common use * Allow styling via css Thanks, Brian Adkins read more about Recommendations for JAVAScript drop-down menu code

Hi, I have created a table where the header columns link to an AJAX function which calls a PHP file and returns content - the purpose is to sort the table on the heading. The code snippet is: <th scope="col"><a href="JAVAscript:;" onclick="loadBookingContent('<? php echo $SERVERPAGE_URL . SORT_BY_BOOKING; ?>','innerhbl')">Booking</ a></th> <th scope="col"><a href="JAVAscript:;" onclick="loadBookingContent('<? php echo $SERVERPAGE_URL .

SORT_BY_CUTOFF; ?>','innerhbl')">Cutoff</ a></th>The $SERVERPAGE_URL variable also contains one parameter, a session ID I'd like to convert this to DOM and store the code in an external JS file thereby separating the JAVAScript code from the HTML.

Message from dan Most recent post: 10/28/2007 3 authors and 6 replies. Hi I'm creating a very basic Ajax "Suggest" type script. I have the server side OK, and the response gets back OK. I have had to use responseText, as for some reason xmlResponse does not seem to work if more than one <message> element is present. But that is not the point of this post, so I'd better get to that. Once I have the list of values that match the user's search term, I display them as a list in a <div>. When the user clicks on one of the list, that value is placed into the textfield. Here are three ways I attempted this, but the only one that allows anything other than the last element to accept any kind of focus is the one that uses innerHTML for the entire thing. Can anyone tell me why the other two do not work? They all display pretty much the same, until you move the cursor over the list. The last two automatically move the focus to the last item on the list. I should add that I have only tested these in IE 6, and Firefox 2 (both for Windows). Any pointers with this very much appreciated. Cheers Dan Assume all of the following are performed within a for loop // This is the one that works ss.innerHTML += "<div class='norm' onmouseover= \"JAVAscript:this.className='over'\" onmouseout= \"JAVAscript:this.className='norm'\" " + "onclick='SetSearch(this.innerHTML)'>" + text + "</div>"; // This does not work var d = document.createElement('div'); ss.appendChild(d); d.in read more about innerHTML works, but DOM does not - Please Help

Message from dhtmlkitchen Most recent post: 10/27/2007 4 authors and 23 replies. JSON We all know what it is. In ECMAScript 4, there's a JSON proposal: Object.prototype.toJSONString String.prototype.parseJSONThe current proposal, String.prototype.parseJSON, returns an object. This is very poor design. It's worse than Date.parse(s), which returns a Number (not a Date). The current proposal, Object.prototype.toJSONString, complicates objects with responsibility that they shouldn't necessarily have. It will be easy to misuse. It'll conflate Object.prototype with implementation details possibly leaking into places they should not. Instead of keeping reduced access, it maximizes access. It doesn't allow the functionality to be tested and debugged independently. If these features go in the language, implementations and library authors will be required to handle this method for all objects, of any type, forever. The change will be permanent and unretractable. This feature isn't critical; it can be added at any time. The flip side to that is that once added, it cannot be removed. ever. Alternatives 1. A built in JSON object A built in JSON object'd keep the JSON serialization/parsing independent. It'll be easy to learn, easy to extend, easy to read and maintain code that uses it, and it'll fulfill the requirements. It won't complicate Object.prototype. JSON.parseFromString( s ); JSON.toJSONString( jsonObject, pretty ); 2. A JSON Interface A JSON interface can be implemented to allow a cl read more about Current JSON Proposal in ES4

Message from Dr J R Stockton Most recent post: 10/26/2007 4 authors and 5 replies. In current JAVAscript, the handling of date and time, whilst powerful, has some minor flaws and several omissions. In particular, while the lack of ISO 8601 support can be dealt with in code, it's often done inefficiently or wrongly.Date-handling suggestions for ECMAScript 4 or 5 :- document.sourceDateHeader A string copying, exactly, the data part of the Last-Modified header. Require that new Date(string) shall always read it correctly (it probably always complies already). Consider the possibility of a variant so that, for a page constructed at run-time, one might be able to get both the instant of design and the instant of constructing the data ??? Granted, "document." is a DOM matter. So : Dobj.setSourceDate Dobj is loaded from the Last-Modified header. Dobj.getSourceDate Return the date/time in the same standard form.Let Dobj be a Date Object. LCT is Local Civil Time. Implement, for ISO 8601, routines like these :- Dobj.toISOlctString() Returns "yyyy-mm-dd hh:mm:ss +-offset", local civil time Dobj.toISOutcString() Returns "yyyy-mm-dd hh:mm:ss UTC", UTC/GMT Dobj.toISOlctOrdinalString() Returns "yyyy-ddd hh:mm:ss +-offset", local civil time Dobj.toISOutcOrdinalString() Returns "yyyy-ddd hh:mm:ss UTC", UTC/GMT Dobj.toISOlctWeekString() Returns "yyyy-Www-dd hh:mm:ss +-offset", local civil time Dobj.toISOutcWeekString() Returns "yyyy-W read more about ECMAScript 4+ Date proposals

I have been tasked to figure out a way to communicate from a JAVAScript /XUL client to a server, but without using a web server.I have been researching different possibilities, and I have come upon <a href = "http://aflax.org">aflax</a>, which is a library for imbedding flash in JAVAScript.
