I will try to exemplify my problem in the best possible way.
I am not responsible for adding code to the site. Most of the events were added via code, not by GTM. The problem is that they do not fire and do not count within GA.
My doubts are:
1 - Why do events not appear in GA?
2 - Even if the events were implemented directly in the code, is it possible to see it in the GTM debug?
3 - How can I check if these events really exist inside the code?
Have you added the correct tracking ID as a Tag in Tag Manager?
Not sure here
Press F12 when you are on the page, where the code is supposed to be. You will open the Inspect tool. You will see a lot of code there, try pressing Ctrl+F and searching for your code.
I would like to implement a "spell check" for my GWT rich text area. I do understand that Firefox and other browsers automatically highlight words with misspellings, but I need to be able to warn the user before they submit a form that there are potential misspellings if they ignore the "squiggles".
Is it possible to use a javascript call to see if the default Firefox spell checker has detected errors? I could use that to stop the form from being submitted with misspellings.
Any thoughts out there?
Thanks,
Jeff
Firstly, you cannot guarantee that your user is using Firefox (or a browser that has spellcheck). Secondly, I do not believe that you can access most browser-level components from your JavaScript code.
You can find spellcheck libraries and call them accordingly. See SpellCheck.java as a starting point, but I'm sure there are many more.
I'm looking for a way to print from web without prompting the print dialog (I just made the question).
I found This method for Firefox and it seems to work, but it obviously will affect all websites. So I'm thinking of developing a Firefox Addon that makes this configuration to affect only specific websites.
I don't know nothing about building Firefox addons, but if it's possible to change settings this way I will learn how to do it.
So my question is.. Is it possible to set config settings on Firefox from a Addon and for specific websites?
Thanks a lot.
If you are going to develop a Firefox addon you could "easily" replace the print button and delegate to the standard print action on normal websites. For a list of URLs, i.e. your web site, you temporarily set print.always_print_silent to true and be done with it.
For modifying a preference in an addon you would something like this:
// Get the "accessibility." branch
var prefs = Components.classes["#mozilla.org/preferences-service;1"]
.getService(Components.interfaces.nsIPrefService).getBranch("accessibility.");
// prefs is an nsIPrefBranch.
// Look in the above section for examples of getting one.
var value = prefs.getBoolPref("typeaheadfind");
// get a pref (accessibility.typeaheadfind)
prefs.setBoolPref("typeaheadfind", !value); // set a pref (accessibility.typeaheadfind)
(taken from this snippet).
One way is to provide your own implementation of the printing prompt service. You could then inspect the window being printed and turn on silent printing if you want to bypass the print dialog. You might need to retrieve the original service to handle the cases that you don't want to. I couldn't find much documentation but there's some related documentation here.
Some web pages such as GMail and Reddit(with the Reddit Enhancement Suite) have useful keyboard shortcuts that I'd like to use. However, whenever I start typing on one of these pages, the first onkeypress event fires, but then the "Search for text when I start typing" search bar opens and blocks further keys.
I don't want to disable "Search for text when I start typing" as I use it on most other web pages. Is there any way to selectively disable it, or to make a keyboard shortcut/bookmarklet to toggle it?
To disable this in firefox, just go to "Options->General Tab->Browsing and disable "Search for text when I start typing". More info here . This is very useful in some cases, for example when you try to play WebGL games or when using pages like Gmail or Protonmail that have their own kb shortcuts.
UPDATED to version 73.0.1- In previous versions of Firefox this is in "Tools->Options->Advanced->General Tab" or in "Preferences->General->Browsing"
This is still an issue huh? I love this feature but It also bothers me every now and then. There are some pages that get it right. I never dug into how they do it. For instance:
zty.pe - JS browser typing game. Would be pretty bad if typing caused searching here. It actually captures the keys just when the game starts and NOT by default on the page.
That is not Firefox or any other browser feature. To do this, you have to write server and client side code.
Catch text that user types into input, and send it using preferably AJAX to server-side script. Then server side script should look up for matches in DB (some search engine), and return possible combinations. All you have to do on client side (JS) is to show returned results in some nice way - like in google - you can use for example simple html lists, but you have to code some css to make it look properly. Also nice feature is to code JS to work on up/down keys and enter for selecting element (it should also work for mouse).
It's not very simple to do by yourself, but you have now idea how to do it. You could also google for some scripts - surely there is something :)
Good luck!
What Firefox add-ons do you use that are useful for programmers?
I guess it's silly to mention Firebug -- doubt any of us could live without it. Other than that I use the following (only listing dev-related):
Console2: next-generation error console
DOM inspector: as the title might indicate, allows you to browse the DOM
Edit Cookies: change cookies on the fly
Execute JS: ad-hoc Javascript execution
IE Tab: render a page in IE
Inspect This: brings the selected object into the DOM inspector
JSView: display linked javascript and CSS
LORI (Life of Request Info): shows how long it takes to render a page
Measure IT: a popup ruler.
URL Params: shows GET and POST variables
Web Developer: a myriad of tools for the web developer
Here are mine (developer centric):
FireBug - a myriad of productivity enhancing tools, includes javascript debugger, DOM inspector, allows you to edit the CSS/HTML on the fly which is highly valuable for troubleshooing layout and display problems.
Web Developer - again another great developer productivity tool. I mostly use it for quickly validating pages, disabling javascript (yes I disable javascript sometimes, don't you?), viewing cookies, etc.
Tamper Data - lets you tamper with http headers, form values, cookies, etc. prior to posting back to a page, or getting a page. Incredibly valuable for poking and prodding your pages, and seeing how your web app responds when used with slightly malicious intent.
JavaScript Debugger - has a few more features than javascript debugger provided by firebug. Although I must admit, I sparingly use this one since firebug has largely won me over.
Live HTTP Headers - invaluable for troubleshooting, use it frequently. Lets you spy on all HTTP headers communicated back and forth between client and server. It has helped me track down nefarious problems, especially when debugging issues when deploying your web app between environments.
Header Spy - nice addon for the geeky types, shows you the web server and platform a web site runs on in the status bar.
MeasureIt - I don't use this all too frequently, but I've still found it valuable from time to time.
ColorZilla - again, not something I use all that frequently, but when I need it, I need it. Valuable when you want to know a color and you don't want to dig through a CSS file, or open up a graphics editing app to get a color embedded in some image.
Add N Edit Cookies - this has been a great debugging tool in web farms where the load balancer writes a cookie, and uses the cookie value to keep your session "sticky". It allowed me to switch at will between servers to track down problems on specific machine. Also a good tool if you want to try to mess with a site that uses cookies to track your login status/account, and you want to see how your code responds to malformed or hacked info.
Yellowpipe Lynx Viewer Tool - yeah I know what your thinking, lynx, who needs it, its so 1994. But if you are developing a site that needs to take web accessibility into account (meaning accessible to users with visual impairments who use screen readers), or if you need to get a sense of how a web spider/indexer "sees" your site, this tool is invaluable. Granted, you could always just go out and grab Lynx for yourselfhere's the windows xp port that I use.
I've got a handful of other addons that I've used from time to time that I'll just quickly mention: FireFTP (one I installed wasn't stable and I've not tried a newer release), Html Validator (also found this one unstable, least back when I installed like a year ago), IE Tab (I usually just have both IE and FireFox open concurrently, but that is just me, I know many others that find this addon useful).
I'd also recommend the Web Developer extension by Chris Pederick.
As far as web development, especially for javascript, I find Firebug to be invaluable. Web developer toolbar is also very useful.
The ones I have are...
Y-SLow
Live Headers
Firebug
Dom Inspector
One that wasn't mentioned yet is this HTML Validator extension that I found very useful.

MeasureIt is an unnecessary extension to have if you install the Web Developer Toolbar. Web Developer Toolbar includes a ruler as one of its features. Under the "Miscellaneous" category for Web Developer click the option "Display Ruler" to use a ruler identical to the MeasureIt one.
That will allow you reduce the number of extensions needed by at least one.
Firefox addons:
FireBug:helps web developers and designers test and inspect front-end code. It provides us with many useful features such as a console panel for logging information, a DOM inspector, detailed information about page elements, and much, much more.
Web Developer-gives you the power disable CSS, edit CSS on the fly, measure certain areas of a page and much more.
ColorZilla
Just click on the icon, hover over the area you'd like to know the hex color for, and click.
Window Resizer
to make sure the layout is displayed properly in the standard resolutions of today.
Total Validator
validating websites much easier by checking HTML, links, CSS and doing a lot more.
Web Developer for web development. Scribefire if you're a blogger-progammer
For web developing I use the Web Developer Toolbar, CSS Viewer and MeasureIt.
But I'm really not one of those who has a thousand of extensions to do everything. I like to keep things simple.
EDIT: Thanks to Dan's answer I don't need MeasureIt anymore. Can't believe I've never seen that! I guess I'll just have to pay more atention to this WebDeveloper toolbar.
Adding to everyones lists, Tamper Data is quite useful, lets you intercept requests and change the data in them.
It can be used to bypass javascript validation and check whether the server side is doing its thing.
I use Web Developer, it's a real time saver.
+1 for LORI ("life-of-request-info"). It's a very convenient alternative for rough measurements of the load time of a particular web page -- the kind of thing that you might otherwise use an external stopwatch for.
New Tab Homepage. Combined with a "speed dial"-type homepage (a personal, fast-loading page of links that you use frequently), helps you get where you're going faster when you open a new browser tab.
LastTab. Changes the behavior of Ctrl+Tab to let you navigate back and forth between your most-recently-used tabs with repeated presses of Ctrl+Tab, the same way that Alt+Tab works in Windows. Also provides a nice view of all open tabs while Ctrl is still being held down for easy navigation. (The resultant behavior is very similar to the Ctrl+Tab behavior in recent releases of Visual Studio.)
FireFTP is good for grabbing/uploading any necessary files.
I find Hackbar to be quite useful. Very useful if you want to edit the querystring part of the url, to test for vulnerabilities, or just general other types of testing where you might end up with complicated query string values.
I was learning DOM inspector, but I've switched to Firebug.
Some of which has been missed above are here
Load Time Analyzer – View detailed graphs of the loading time of web pages in firefox. The graphs display events like page requests, image loading times etc.
Poster – A must have tool for web developers enabling them to interact with web services and other web resources.
Aardvark – A cool extension for web developers and designers, allows them to view CSS attributes, id, class by highlighting page element individually.
Fiddler is a really great debugging proxy. Think of it as a more powerful version of the "Net" panel in Firebug or the Live HTTP headers.
It used to be an IE-only extension, now it also has hooks into Firefox.
Groundspeed, is useful for testing server side code. It was created for input validation tests during pentest, but can be useful for any test that require manipulating input (similar to TamperData).
It lets you control the form elements in the page, you can change their type and other attributes (size, lenght, javascript event handlers, etc). So for example you can change a hidden field or a select to a textbox and then enter any value to test the server response and stuff like that.
