Firefox and ASP.Net 1.1 and Ajax and Validators, oh my!

antifuse — Thu, 22 Oct 2009 14:20:32 -0800

How can I get Ajax and client side validators working with my ASP.Net 1.1 application in Firefox? Ok, long story short - I've got an ASP.Net 1.1 website, which uses Validator controls and Ajax (ajax.dll, v5.7.22.2)... All of these elements of the site were chosen/implemented before I got here, and before anybody asks, no, it's not within our budget (timewise) to upgrade even to ASP.Net 2.0, let alone the latest and greatest of everything.

The site works fine in IE (of course), but in Firefox (or Chrome... Haven't tried Opera or Safari) I've found that ASP renders the site without any javascript code for the validators, nor does it render the site with any javascript code for the ajax methods that I call.

I've checked, and our web.config is setup to treat Firefox as an "uplevel" browser... And it *does* seem to be using the correct HtmlWriter (ie my pages on FFox are rendered with spans and divs). I've tried creating a PageClient alias using an IE7 user agent in the web.config, and forcing the page to use that PageClient. NOTHING seems to let it generate the Ajax and validator javascript. My research on the net seems to be pointing towards validators simply not ever able to work with ASP.Net 1.1 and Firefox... And I presume that whatever the validators do, the Ajax library is doing as well... But I'm really really really hoping there's a workaround for this. It'll be extremely embarrassing to have to tell the client in this day and age "Sorry, we don't support non-IE browsers with this release".

Can greasemonkey open a link in a different browser?

Roger Dodger — Wed, 23 Sep 2009 09:51:32 -0800

Is it possible to use a greasemonkey script in Firefox to open specific links in Internet Explorer? If so, what would it look like? The particular element in the HTML page is an input button which executes some javascript, which opens a different webapp in a new browser window. However, that webapp only works with IE, and I use Firefox. The element looks similar to this:

<input value="New Webapp"  class="btn" name="webapp" onclick="openIntegration('/servlet/servlet.Integration?scontrolCaching=1&lid=00b70000000zL1t&eid=50070000009tNYv&ic=1', 'height=600,location=no,resizable=yes,toolbar=no,status=no,menubar=no,scrollbars=1', 1)" title="New Webapp" type="button" />

The openIntegration function (which sits in a separate .js file) looks like this:

function openIntegration(url, props, positionType) {

    var newWindow = window.open(url, "_blank", props, false);

    if (positionType == 2){

        newWindow.moveTo(0, 0);

    } else if (positionType == 0){

        newWindow.moveTo(0, 0);

        newWindow.resizeTo(self.screen.width, self.screen.height);

    }

}

Can javascript be used to specify a browser other than default? How would I go about doing this?

Zoomy Lightbox a la Firefox?

CaptApollo — Wed, 19 Aug 2009 08:09:06 -0800

I am in love with the zoom-in dialog box used for the video demo on the Firefox 3.5 'what's new' screen. Is there a cross-browser equivalent? I know about various 'lightbox' scripts, but this zoom thing is new to me.

Suppress right-click menu on a web site

maxwelton — Sat, 30 May 2009 02:50:40 -0800

Is there a way to disable the right-click menu on a particular web page I visit that isn't managed by me? I play a solitaire game on a particular web site fairly often. It's not a Flash game, nor is it a Java applet, I suspect it's simply JavaScript.

The game allows you to use both left and right clicks, each performing different actions, but every time you right-click the normal browser right-click menu appears...very annoying in this context.

Is there a way for me to tell my browser I don't want the right-click menu to appear on this one particular page (or its domain, if that's easier)? I have greasemonkey installed, so a GM script would be ideal, but I haven't been able to locate one.

I'm on Windows, using FF. Thanks mucho for any ideas. (I could possibly write my own script if pointed in the right direction.)

How to all Javascript to run only within it's own domain?

Solomon — Sat, 16 May 2009 10:42:15 -0800

Is it possible to make NoScript disable certain site's scripts only on certain sites? For example, I'm on site-a.com, and there's javascript on there that is necessary for that site to function, so I allow it. However, site-b.com uses some scripts from site-a.com. I don't necessarily want site-a.com's scripts running on site-b.com, for whatever reason.

How can I set site-a.com's scripts to run only on site-a.com?

I did try asking this question at the NoScript forums, but the post was deleted.

Getting buttons to work on Firefox

TheRaven — Tue, 28 Apr 2009 05:55:28 -0800

Javascript (and other protocols) do not always work on Firefox/Mac. I am running a Mac with Firefox 3.0.10. All too often I find that clicking on buttons on certain sites, where the button uses Javascript (but also asf and php), nothing happens. Usually I find a work-around but I am curious as to why it doesn't work. Here is a case in point - http://www.cityinn.com/london/reservations.htm. Clicking on the Check Availability button (after filling in the details) does nothing. Things I have tried:

1) Using other browsers (Safari, Camino). Sometimes this helps but not here.
2) Disabling and even uninstalling all my add-ons. Rarely helps.

So, is this some Mac setting, some dumb thing I am or I am not doing or just lousy design by various websites?

Firefox javascript tab closure command?

bbranden1 — Sat, 12 Jan 2008 11:13:55 -0800

Firefox javascript command: how to close a tab? Last week you helped me create a toolbar bookmark for scrolling down a half page in Firefox using the command javascript:self.scrollBy(0,300); as seen here. Now I'd like to add a second command to that bookmark: a command to close the active tab. The button then would close the active tab and subsequently scroll down a half page of the next tab that appears. In my reading there appears to be some difficulty making using javascript to close tabs in FF 2.0, and not all pre FF 2.0 solutions currently work. Ideas?

Spaces Cause Strange Behavior in TextArea

GregX3 — Fri, 27 Jul 2007 10:39:46 -0800

At least in Firefox I'm seeing an undesirable behavior in textareas. My question is how to fix/avoid it. Here's the problem. Go to a textarea in Firefox. (The ask.metafilter ask a question one will do fine.) Type enough characters to fill a whole line of the textarea e.g., kkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkk... Now put a single space in front of that line. It moves the line one line lower instead of just putting a space in front of the characters which is what I would prefer i.e., treat a space like any other character. It's really driving me crazy on my website where I want to have users format precise code. Let me know if my explanation isn't clear and I'll try to explain it better.

How to create a CrossBrowser Bookmarklet?

mickbw — Wed, 24 Jan 2007 22:08:15 -0800

I have written a bookmarklet that works in Firefox but not in IE6. How can I change it to be supported cross browser or even as a separate bookmarklet to get the same results. javascript:Qr=document.getSelection();if(Qr)location.href='http://jobsearchlog.com/ba.cfm?ad='+escape(Qr)+'&description='+encodeURIComponent(document.title)+'&tags=%s'+'&ad4user=mickbw&url2job='+window.location.href;

Much of the JS was taken from the send to Delicious bookmarklet but I've never seen it work in IE anyway.

The purpose of the 'let is to send whatever text in a page has been selected, the URL and page title and submit the values into a database for use in my web application. In Firefox they would also be able to specify tags to be included in the insert.

Any suggestions on making this work in IE?

javascrtipt access to style sheets.

Tryptophan-5ht — Sun, 29 Jan 2006 16:19:55 -0800

javascript question: im looking for a way to access the style sheet text in firefox. im looking for the full text - like with the comments and everything, not just the cssText attribute of each individual cssRule.

for an example, see the "Edit CSS" option in the developer plug in.

background information: im writting a greaseMonkey script that will allow you to view/edit the markup and css of a page you're viewing. In order to make the CSS editable, i need a way to quickly and easily grab the text from all the style sheets and move them into one style tag, then disable the originals. Ive got a working copy, except that i have to cycle through all the cssRules and grab the text of each and append it to the new style tag - which is slow, destroys the orginal formatting and leaves out any comments.

Where oh where has my JavaScript gone ?

mikeinclifton — Tue, 15 Nov 2005 20:46:33 -0800

I want to go back to FireFox 1.0.4 because JavaScript has failed me in 1.0.7. How do I do so. . .or is there hope for my 1.0.7 ? I've searched Google, the archives here, and the Mozilla Forums, but no one can tell me why, after downloading Firefox 1.0.7, that Javascript quit and my GoogleMaps dont map. It happened instantly, after download.

They say to check the box in Options/WebFeatures, but I've checked and unchecked that a few times. I've checked and unchecked the 'Load images-from the originating web site only' setting, but to no avail.

I've asked friends and run three different anti-virus programs (just in case) in addition to my Norton AV, but alas, I'm still JavaScript free in my Fox and XP.

When typing in www.maps.google.com the page flashes then goes to this - "http://maps.google.com/?output=html"

So how do I go backto FireFox 1.0.4 ?

How Can I Write Cross-Browser Links?

RKB — Tue, 25 Oct 2005 12:13:01 -0800

Without using any plug-ins or extensions, how can I always force a link to open in IE, regardless of the client browser? I'm trying to do a fairly simple web port that has three existing ActiveX ojbects that aren't about to get re-written. Of course it works fine in IE but doesn't in Firefox. I've already implemented some browser detect code that tells people "get thee to IE" if they try to launch the pages containing the ActiveX objects.

What I'd prefer, though, is some kind of client-side link that allows any user the same kind of functionality that Firefox's "View In IE" plugin does. The ActiveX objects launch in a new, untitled, no-scrollbarred window anyway -- I'd like to be able to force those links to always open in Internet Explorer instead of the default browser. A much more seamless user experience that way.

Is it even possible to do this programatically? Or am I going to have to stick with providing browser-specific directions throughout the web app, stating that it works best in IE? Thanks.

Firefox 1.5 Beta : some of my javascript bookmarklets stopped working. Any ideas? I have two little bookmarklets that resize my browser window, a default and one that's tall and skinny for reading books. I managed to cobble them together without really knowing what I'm doing, and on Firefox Beta they have magically stopped working. I've looked around a bit and have no clue why they don't work. Other .js bookmarklets work fine.

Here's the code:
javascript:resizeTo(600,screen.availHeight-40);moveTo(2,2)
javascript:resizeTo(screen.availWidth-50,screen.availHeight-40);moveTo(2,2)

Help! I use these all the time and besides, it perplexes me slightly :(

How do I assign a hotkey to a Firefox bookmark?

arathorn — Tue, 23 Aug 2005 19:20:15 -0800

I have a bookmarklet that I'd like to run by a pressing a hotkey in Firefox -- any suggestions? I've set up a mouse gesture to do this, but I'd like a keyboard shortcut as well.

Firefox image resizing driving me mad

Pericles — Wed, 24 Nov 2004 11:55:28 -0800

FireFox filter. This is driving me mad. My website has a little JavaScript (inside) to drag in a random image. Each image is 150 wide (varying heights). IE displays them fine. Firefox 1.0 resizes certain images. Anyone know why? The JavaScript specifies the width (but not the height as each image is different):

var choice = pickRandom(range);

document.writeln('<a href="about.htm"><img src="images/bl'+choice+'.jpg" 

class="randompic" width="150" alt="blah"></a>');

It's easy to see the browser re-sizes them as it has that wierd pixellated quality that browser-resized images have (+it spills out of the containing div).

The images are at the bottom of the yellow side-bar (self-link, sorry); refreshing the page brings new ones. I've checked Bugzilla, but can't help feeling that I'm going mad ...

Firefox / Javascript question... how do I get the mouse X/Y position across frames?

holloway — Mon, 02 Aug 2004 01:32:55 -0800

Firefox / Javascript question... how do I get the mouse X/Y position across frames (relative to the browser window, of course) Say I've got a frameset like

--------
|    | |
|    | |
--------

Now if I have a document.onmousedown = someFunction and then have function someFunction(e), then the event 'e' will have e.clientX and e.pageX which hold the current mouse position relative to that frame. If I'm in the right frame though, then I'd need to add the width of the left frame to get the position relative to the browser window.

Is there some way to get the mouse position outside the frames, or without an 'e'? It's been driving me bonkers.
