Firefox3: Window.focus() And Blur() Between Tabs Not Working
Apr 8, 2009
I'm trying to build a data navigation utility that will allow a central "map" page to control a number of tab pages that are loading individual pages from a large set of HTML. All are local file://localhost/, with localhost popups enabled. (for dev/testing all popups are enabled since firebug 1.3.3 has problems loading localhost .js code) preference to "raise and lower windows" has been enabled I am using firefox 3.0.8 on FreeBSD 6.4
Anyway, I can't get window.focus() and blur() to work between cooperating tab/windows who know each other's names.
Here following are two cooperating mirror tab pages that i'm trying to get working. Have tried a number of combinations of the focus() and blur() calls. Have tried with/without messaging. Messaging works fine.
I have noticed that the calling tab seems to unload/reload as a result of the click event. This still allows the message to get through OK, but I guess the reload could be taking the focus again.
An annoying alert() dialog could of course get focus to the message receiver, but it requires another click to get it out of the way.
The concept of these focus() and blur() calls is so simple, and I've searched all over the web for examples, but nothing seems applicable.
Have also seen that this may be a bug in Firefox.
======== code for "mirror" pages "focus1" and "focus2" follows:
i am having trouble understanding what the difference is between BLUR and FOCUS. I need to include these functions in my form and i am unsure what these features do and how i incorporate these into my form.
I'm having problems with applying focus() to an element inside a blur() event handler. I get different results in different browsers. Specifically, IE and Opera seem to work fine, Firefox doesn't seem to do anything, and Chrome and Safari only do half of the job. Basically, I have an <input> with a blur() event handler attached to it. The event handler contains the code to apply focus to that same input, effectively disallowing the user to remove focus from the input.
I'm working with ClueTip and have run into some oddities.In particular, I want to show ClueTip when a textbox receives focus.The source shows me that I can use activation:'focus' for this and that will result in the cluetip showing on focus and disappearing on blur. Showing the cluetip is working fine, blurring is not.[code]
I have a form with a certain number of elements, i want it to at first only display the first, then when i deselect that element the next one is shown and focus moved to that and so on until the end of the form. Im new to jQuery and just
I'm trying to create a control which when the mouse button gets pressed on one div an absolute positioned div pops up in place of the cursor. From there the cursor should interact with the dialog before the mouse button is released. In other words one element will catch onmousedown, display the popup, and the popup element will catch onmouseup. This works fine in IE as the popup automatically accepts following events, but my problem is in Firefox.
In Firefox everything behind the popup still receive events even though they can't be seen (hidden by the popup). I have to release the mouse button and then click on the popup again before it accepts the onmouseup event.
I also used a different cursor on the popup to see if Firefox recognized it was there at all. Still the cursor doesn't change until I release themouse button and move the cursor across the popup element.
I've tried focus/blur, timeout delays, hiding the first element (the one which receives onmousedown) but nothing works.
The only thing that works is hiding the entire body and then using setTimeout to show the entire body again 1ms later. Obviously though that is very ugly.
a) Keyboard users to see a focus outline on navigation links. b) Keyboard users to see the outline still there if they use the browser Back button, and continue tabbing from that link onwards. c) Mouse users to NOT see an outline if they use the browser Back button.
This all works fine in IE and FF but in chrome the options are still shown after clicking the element. I've been racking my brains for hours on this and, no matter what method I use, I can't get this to work correctly in Chrome.
I am doing a simple example of autocomplete textbox.Well whenever I am typing anything in the textbox it shows me the existing options as we know the default functionality of autocomplete textbox. Now I need that when I select one of the options from the autocomplete list droping below the textbox the blur function should execute so that the focus should get away from the textbox. I have tried document.getElementById('text1').blur() but it is not working in chrome and safari.
I am trying to get an accordian script to work within tabs, here is the code I just can't get it to work, I realise the issue of the inactive tab displaying none which causes problems, I have tried a few work arounds but still not working [code]...
full sample script which demonstrates the problem, inner tabs company/department come up as list instead of tabs.I have already tried what People have suggested that inner tabs should also be tabified via jquery but it doesn't work all the examples I have seen e.g.URL... use topmost div for jquery tabs call.[code]
