 | Brandi, It seems that FF doesn't like that form of javascript URL. I have seen "javascript<b></b>" before but have no idea where it comes from. As far as I know the <b></b> has no place in there but would like to know why there are so many examples of it …  |
| | JRW, For undefined members, [ICODE]typeof[/ICODE] returns [ICODE]"undefined"[/ICODE], which (somewhat confusingly) is not falsy! The reason is that [ICODE]typeof[/ICODE] always returns a string (including [ICODE]"undefined"[/ICODE]) and any string that is not empty is also not falsy. Empty strings are falsy. In fact, [ICODE]typeof[/ICODE] always unambiguously returns a string (unless its argument … |

| | Fury, Ultimately some line of code somewhere is using the result of getElementById(txtindex") instead of getElementById(txtupdate"). All you have to do is track it down. If it's not obvious then I would immediately suspect the use/reuse of a global (or outer) variable. Suggest you give this first consideration. To analyse … |

| | JRW, I'm afraid ththe "onreadystatechange" approach is not generally applicable. It only applies to certain, very specific types of object. You might be tempted to use [ICODE]setInterval(...)[/ICODE] to monitor your object property but that's a very inefficient way of achieving your aim. If I understand correctly, a better way to … |
| | Vantrax, Typical reason for difference in local/remote behaviour in something like this is the permissions on the counter.txt file. Most FTP clients allow you to set a remote (*nix) file's permissions, eg. in Cute FTP [I]right-click > Properties/CHMOD[/I]. It's probably 644 by default. 666 should do it. [B]Airshow[/B] |
| | JRW, You can build a JSON string like that if you want ([ICODE]data[key] = value;[/ICODE] will get you started) but unless you particularly need a JSON string, you appear to be trying to replicate something that's native to HTML/browsers (and has been since time immemorial - ie Mosaic, IIRC). HTML … |
| | Peck, The main thing is that by using <button>Login</button>, the form's onsubmit event won't fire. Try putting an alert right at the top of validate_login(thisform) and you will find that it's never called. You can use : [LIST] [*][ICODE]<input type=="button" value="Login" />[/ICODE] for a standard button, or [*]eg. [ICODE]<input type="image" … |
| | Nothing immediately wrong but I suggest : [LIST][*]Avoid "extend". It's just possibly a reserved word (even though it's not part of the javascript language). [*]I guess that element '#abc' is a table. Try using <tbody id="abc">...</tbody> inside the table and add your row to it rather than directly to the … |
| | MrNG, Without doubt - method 2. Otherwise you are reliant on someone else's server being up-and-running and still serving exactly the same version of jQuery on which you did all your rigorous testing when you built your app. Whereas Google are probalby as reliable as an organisation can get, why … |

| | Albert, It sounds like your form is submitted and the server then re-serves the page identically to the way it was served the first time. Hence the form is devoid of the user's entered values. If you want the server to re-serve the page with the user's data in place … |

| | Masocha, The W3C standards don't specify in great detail how radio buttons (and other HTML elements) should be rendered, therefore you will find differences from browser to browser and OS to OS.

| | chathuD, Sticking with basic coding, there's no particular advantage in having a [ICODE]new Image()[/ICODE] for the images already loaded automatically by the HTML. All you need for these is to store each image's src string so it can be recalled on mouseout. Meanwhile, the rollovers are not preloaded automatically so … |

| | Re: form validation Achiman, An onclick event in an input field can't be used to suppress form submission. The solution is simple but not obvious.

| | Akabir77, It's not possible to call java/JSP function directly from javascript (same with php, asp, perl, ssi etc).

| | Zarah, The HTML has a bunch of unbalanced <a> tags (all without </a>). As they do nothing, you might as well delete them.
