Use the rows[] and cells[] collections to validate the desired cell(s) in the desired row(s). Using them together [iCODE]rows[i].cells[j][/iCODE] makes accessing a table almost as easy as accessing a two-dimensional array.

Since you mention querying a database, I assume that you have server-side scripting; if so, you should start there (as they all have a way to do what you want). That aside, here [url]http://msdn.microsoft.com/en-us/library/ms532998(VS.85).aspx[/url] is a [B]complete [/B]tutorial using only javascript. Assuming that a table already exists, you don't need …

The first problem is that the correct spelling is [iCODE]getElementsByClassName[/iCODE] The second problem is that some browsers do not support it [url]http://www.quirksmode.org/dom/w3c_core.html#fivemethods[/url]

[QUOTE] client-side JavaScript for version 1.3[/QUOTE] Obsolete.

Webkit browsers start executing javascript that is not tied to any event before the DOM finishes loading. The exact cure depends on what is where, but the general idea is to put everything in onload= or readystatechange= event handlers. Sometimes moving everything to the end of the body [out of …

[QUOTE]get me started on the calculate function [/QUOTE] The first problem is that [iCODE]function calcuate()[/iCODE] is misspelled.

No container is needed. Just define a placeholder IMG with the desired width= or height= (but NOT both, and do NOT use style). When the src= is changed, the browser will [by default] scale the image without changing the aspect ratio. Note: the scaled image may look awful [especially if …

[QUOTE] function activateLink(obj) { obj.className = obj.className.replace("link_fresh", "link_visited") // do something else such as display stuff you want to display } [/QUOTE] That only toggles one object.

[QUOTE] return [img.width, img.height]; [/quote] Try [CODE]return [img.clientWidth, img.clientHeight];[/CODE] instead. Note, however, that if you need to know the total area occupied by the element (not just the area of the actual image) you will have to deal with borders, etc.

Without seeing your code it is not possible to give an exact answer. In general, however, the same approaches used to 'populate' the <div> in the first place [[iCODE].appendChild()[/iCODE] or [iCODE].innerHTML +=[/iCODE] or whatever] could be used 'onclick' in the accordion to add to the <div>.

A bookmarklet alone can't do it, but a bookmarklet that calls an extension in principle could. These [INDENT][url]http://www.snaphow.com/2-ways-to-add-an-useful-mini-notepad-to-firefox/[/url][/INDENT] may be marginally better than the window.open method you were previously using.

That is an expected result. On most 32-bit platforms the largest javascript integer is 2^31-1 and the maximum precision of a floating point number is 15 digits.

[QUOTE] get the selected text from the i-frame where the source is from different domain [/QUOTE] By design, no modern browser will do that. For special cases [your own desktop or intranet] more-or-less ugly work-arounds are possible; in the general case, none of them is likely to be practical.

Some of the more-or-less effective workarounds are discussed here [url]http://www.mezzoblue.com/archives/2010/05/20/ie8_still_fa/[/url] but AFAICS there is no perfect solution yet. Googling turns up a number of similar ideas, and combinations.

If each IFRAME is responsible for toggling its own text, the solution is almost trivial. I have posted examples of toggling properties in two other current threads in the last 24 hours. Note: manipulating classes (instead of toggling properties) can get complicated. For starters, 'className' [as opposed to 'class'] is …

[QUOTE] load different images into page every time the website is viewed? [/QUOTE] Write an onload= function to set the src= field of the IMG(s). You can use Math.random() to compute filenames based on a pattern (cloud0.jpg, cloud22.jpg, cloud7.jpg, etc.) or choose arbitrary filenames from an array [ICODE]["sky.jpg","cloud.gif","rain.bmp","snow.jpg"][/ICODE].

You can set [iCODE]onclick="doSwap(this)" [/iCODE]on each element (so they all invoke the same function). That single function [iCODE]doSwap(that){}[/iCODE] cycles through the elements of interest, setting each associated color to 'default' and each associated <div> to display:none. Then the special color and display:block can be set for (that) one. This doesn't …
