Safari: hidden IFRAME getting tab focus
Hi,
I have a page. There is a section 'sidebar' where bulleted text is there. Just after first bullet there is a hidden IFRAME. That go visible on clicking of that bullet text.
My problem is with Safari Browser in Mac and WindowsXP.
When we press the tab after first bullet link instead of going to next bulleted text the focus goes to the hidden IFRAME. How can I avoid the focus to hidden IFRAME.
I tried both visibility:hidden and display:none still it is getting focus in Safari
Please help.
I am posting the code that have the issue in Safari 3.1.2
<!doctype html public "-//w3c//dtd html 4.0 transitional//en">
<html>
<head>
<title>Safari Iframe Testing</title>

<body>
<input type="text"/>
<input type="text"/>
Some Link 1
<iframe style="display:none" ></iframe>
Some Link 2
Some Link 3
</body>
</html>
if I uses tabindex="-1" in iframe that resolve the issue. will it be a suitable tweak?

I am super frustrated with Safari in ios 7. I do not have the pages icon on the bottom right of Safari ios 7. When I press the plus sign at the top right I see 'private' on the bottom left side but there are no buttons on the bottom right at all. I am trying to get Safari to have the tab Rolodex look of the tabbed windows. So I can see the pages. Hope this is making sense. Why am I not seeing the pages button on the bottom right of Safari?
Thanks!Bummer! Hopefully this will change in the future. At least I know now that I am not crazy for not seeing the pages icon! Thanks so much :)

In Safari 5.1, is there a pin tab option, like Chrome and Firefox? I looked for an extension, but I also cannot find a search button in the Extensions library of Safari.
I am sorry to say it is not possible I did alot of reasearch and it did not show up.
How To Optimize Safari for a more Chrome-like Experience
While I prefer Google’s Chrome web browser, lately I’ve been switching back and forth between Chrome and Safari for different tasks. (Evernote for example works much more seamlessly with Safari, as a quick perusal of the Chrome plugin page will tell you.) If you prefer Chrome, it’s easy to get frustrated with the lack of consistency between the two browsers but there a couple of tips and tricks you can implement in Safari for a more Chrome-like experience.
Extensions
With the introduction of Safari 5, users can now customize Safari with extensions much the same way they can in Chrome and Firefox. To install an extension, navigate to the Safari drop down menu and click on Safari Extension Gallery, which will bring you to the microsite seen above. There’s been an impressive amount of development on Safari extensions, and while there aren’t as many available for Safari as there are for Chrome, here are a few I’ve found hepful in replicating some of the better built-in features of Google’s web browser:
Reload Button by John Siracusa: One of my pet peeves with Safari is the lack of a proper Refresh button in the toolbar bar. This extension placing a Refresh button adjacent to your address bar; you can change its location by navigating to the View menu in Safari and selecting Customize Toolbar.
Add to Google Reader by Rob Wilkerson: I’ve never got the hang of Safari’s built in RSS reader and it’s always left me frustrated anytime I try to use it. This extension links the RSS button to your Google Reader account and replicates the functionality of the orange RSS button in Chrome. Now you can add your favorite RSS feeds to Google Reader or iGoogle by simply clicking the RSS button in the address bar!
Tab Support with GlimsOne of my biggest frustrations with Safari is the tab and search support Safari offers when compared to Chrome. Tab manipulation in Safari is very limited. By default, users can open and close tabs or move them to another window or position in the same window and that’s about it. And unfortunately, there aren’t great options in the Extensions gallery for better tab controls. After some digging online, I came across Glims, a Safari plugin that adds a bunch of features to make Safari tabbing more useful. (Get it here: http://www.machangout.com/) Installing Glims will add a Glims icon to your Safari Preferences pane, where you can add or change your Tab functionality. Here are some of the Chrome features Glims enables that I’ve found particularly helpful:
Favicon on tab lables: This is a nice feature that allows you to quickly identify your tabs. Turn this on by navigating to the Tabs Misc option list in your Glims Preference pane.
Undo “Close Tab”: Unlike Chrome, Safari’s built in Tab pane doesn’t include an undo option. Glims doesn’t add this option to the tab dropdown pane but does enable the feature through a command key, CMD-Z. You can enable this feature my navigating to the same Tabs Misc option list in the Glims Preference Pane.
Tabs Re-opening: Chrome offers users the option to automatically restore open tabs from their last session. While you can also restore previous tabs in Safari, you must manually enable this feature every time by navigating to the History menu and clicking “Restore Windows from Last Session”. Installing Glims automates this feature by default; if you want to more control of when and how tabs reopen from a previous session, check out the Tabs Re-opening option in the Glims preference pane.
These are the tab features I use most but there are three whole tab menu options in Glibs that you can play around with. Other features include a focus feature for the last selected tab, tab positioning options and the ability to always open links in a new tab. One Chrome feature that hasn’t been included in Glims that I would like to see is the ability to pin tabs but all in all, this is a very good tool for optimizing your Safari experience.Search Support with GlimsGiven Chrome is a web browser built by Google, you’d expect that the application’s search functionality to be better than Safari’s. In addition to bettering tabs in Safari, Glims adds some search capabilities that replicate a number of Chrome’s built-in features into Safari.
Customize Search Engines: Glims allows users to change the default search engine in Safari’s toolbar search field and also make your own custom searches from the preferences pane. The plug in comes with a predefined set of search engines such as Google, Yahoo, Bing, Wikipedia, Amazon, and Wikipedia.
Setting search keywords and shortcuts: One of my favorite features of Chrome, this lets you create and assign keywords for specific searches. For example, I’ve created the keyword shortcut “WP” for wikipedia searches. Instead of running a search and then clicking from the menu for my result, I can simply begin a search with WP then type the subject I’m looking for, press return and Safari will automatically bring me to that wikpedia entry. An added bonus of this feature is that it works directly from the address bar, just like in Chrome.
Search suggestions: Glim provides search and link suggestions in a dropdown field similar to Chrome, so if you see the result you are looking for while typing simply click on it to navigate to that page. This replicates the Google Instant feature option in Chrome.
I hope you’ve found these tips for Chrome-ifying Safari helpful. If you’ve got any additional tips or suggestions, please share them in the comments section! -

Textbox2 is also enabled when the cursor is in Textbox3 and SHIFT+TAB is pressed,
I tried this with the Focus Listener but i cant able to get the cursor in the textbox. Please help in this, how to do this.

Hi All,
I am having problem on focusing the subTab.
My Requirement is based on the LOV value ,that is at header level the some Detail Sub Tab get disabled & the focus should be on Enabled Tab.
It is working fine for Disabling Tab. But the problem arise when user click on one Enabled Tab and then Changed the LOV value. Then the Tab Get Disabled but focus remain on the disabled tab. I have to click manually on the Enabled tab to get the focus. This focus problem only happen when user click on the Tab, else if LOV value change and user doesnt click on Tab Disabling and Focus is right.... CAN YOU PLEASE HELP!!!! WHY THIS DOUBLE STANDARD BEHAVIOUR HAPPENING??????????????????

"Tab2");

Tab focus progressing to parent window from popup
Hi,
I am using JDeveloper 11.1.1.7.0 version.
I have a bounded task flow with .jsff fragments and I am trying to call another bounded taskflow(with .jspx files) as "Run As Dialog" from this taskflow.
Here I am able to set initial focus to the required input element using <af:document> tag's "initialFocusId" property. Up to this, it is working fine.
When I tried to tab, cursor is moving to next fields as expected. But after completing all the fields and buttons in the popup, tab focus is progressing to the parent window links and buttons.
Is there a way to block the cursor progression to parent window and make it to rotate within the popup window.
Thanks,

We have an af:table component on a page. In order to make the page keyboard accessible, we should be able to tab to that component using the Tab key on keyboard. However, when the af:table component is selected using Tab key, it does not get visual tab focus. So it is hard to tell that af:table component is currently selected by the Tab order.
Is there any way to enforce visual tab focus (dotted lines) around the af:table component?

Hey Folks. Have an AS2 file that keeps TAB focus/order properly when using Firefox or Safari but NOT when using IE. It's fine at first but when I TAB to and select a button the next TAB goes to IE's address bar. This does NOT happen in Firefox or Safari. Can someone please point me to some info on how to avoid this?
hi,
maybe when you reactivate the browser, you reactivate the site(!) and not the applet.
The applet is only a part of the site and has to be activated, too.
I guess this is the problem.
but i got no idea how to fix this.
sorry.

Auto tab focus method is not working in iOS devices please share the ideas why its not working?
Auto tab focus method is not working in iOS devices. Please share the idear i am facing this issue while developing code for devices.
Hi there,
I can confirm this bug.
Not sure if this info is relevant, but this is my experience:
I am on the FIDO network, and so are two other people I know.
We all tried blocking numbers, and calls ring right through. Text messages are blocked successfully. (never tried facetime)
I also tried a ROGERS device running IOS7, and was successfully able to block my phone call from ringing through. HOWEVER, my call was forwarded to their voicemail, I was able to leave a voicemail for the person, and they did get an alert that they had a new voicemail.
I have not yet had a chance to test this on Bell, Telus, or any other carriers.
Spoke to Apple, and they advised me to do a hard reset (hold both buttons to shut off and reboot the phone), and if that fails to do an iOS restore.
I have yet to try this, but hopefully someone will have a better solution. -
I have a question that I'm guessing has a ridiculously simple answer for you gurus, but I still can't figure this out:
For some reason, I've had a couple of instances where the OS will go into a "tab focusing" mode, where hitting the tab will switch to each item and put a blue highlight around it, whether it's in a dialog box or the bookmarks bar in Safari. The highlight doesn't always function as something I can activate with the enter key or arrows, though (as in the Shut Down dialog box). The first instance of this (I believe) went away on its own, after performing an OS update. In either case, I'm pretty sure I haven't accidentally turned on something in the system preferences.
Anyone have a quick and dirty explanation (or better yet, a fix!) for this?Hi Chris
it may be that you un-wittingly hit Shift-F7 which toggles Tabbing between "text boxes & lists only" and "All controls"
I know I've done this a few times

When I open Safari, I keep getting the Jobs video from Tim. Once was OK.ow do I turn it off?
When I open Safari, I keep getting the Jobs video from Tim. Once was OK.ow do I turn it off?
First, go to the website that you wish to make your Home page. Then click on Safari>Click on Preferences on the dropdown menu>Click on the "General" tab on top of the window which should be on your screen>click on the "Set to Current Page" button which is under the Home Page line. This should solve the problem.

Upon opening a new Safari window (option-n) in full-screen mode with OS 10.7, the tab key is inoperative, preventing instant selection of the URL or search fields.
This unusual disability of the tab key negates the whole purpose of opening a new window in Safari, that is – navigating to a new URL or making a search enquiry.
Why is the tab key disabled in full-screen mode in Safari 5.1.1.?
Gaffes like this are unusual.
Has no one at Apple has noticed this?I'm having the same issue. I don't know if you've received an answer but I have a workaround.
Work around #1: When you open a new window or tab, if you hit the Tab key on your keyboard before the URL has finished loading the tab focus stays at the address bar.
Work around #2: In Safari 5.1 preferences on the General tab if you set "New windows open with:" and "New tabls open with:" to something OTHER THAN "Homepage" or "Same page", Safari's tab indexing works as prefered.
I hope Apple fixes this soon.
Hope this helps,

Hidden iframe src = servlet with a persistent connection
Hello all,
I am messing around with trying to embed a hidden iframe in a jsp and this hidden iframe's src is a servlet that never calls out.close().
The code for the servlet is as follows:
while(true)
//here I call a random number generator method and then out.print() the results.
out.flush();
try
Thread.sleep(1000);
catch(InterruptedException ie){ie.printStackTrace();}
catch(Exception e){e.printStackTrace();}This all works fine.
Now I need to grab the results of this endless loop which are currently in an iframe within a jsp and make the iframe hidden and somehow pass the results of this hidden iframe to a div on the jsp. This is the part that I cant get to work.
Any Ideas?
TIA!why not... ditch the iframe and use Ajax to asynchronously fill your div? Toolkits such as Dojo make this fairly easy and cross-browser:

I am facing the following problems with JTextArea inside Jtable Cell
1. blinking cursor not visible on the cell(0,0) first time the UI is shown, although it has the focus
2. blinking cursor not visible on the 5th column (JTextArea) when it receives the focus nor the characters are visible when i start typing. i have to manually double click to force the focus to shift to the cell.
3. focus does not shit out of the 5th column (JTextArea) after pressing the tab key or enter key once. i have to do that twice to force the focus out.
Following is the code which i have implemented. Please let me know what is being missed out to rectify the above problems.

Reposting - JTextArea inside Jtable - Tab, Focus issues
Sorry for reposting this again...I didn't format the code in my previous post.
I am facing the following problems with JTextArea inside Jtable Cell
1. blinking cursor not visible on the cell(0,0) first time the UI is shown, although it has the focus
2. blinking cursor not visible on the 5th column (JTextArea) when it receives the focus nor the characters are visible when i start typing. i have to manually double click to force the focus to shift to the cell.
3. focus does not shit out of the 5th column (JTextArea) after pressing the tab key or enter key once. i have to do that twice to force the focus out.
Following is the code which i have implemented. Please let me know what is being missed out to rectify the above problems.
Thanks.
