A search of this forum brings up some old posts on this subject... several years old... has anything been developed that can make a field blink to grab the user's attention?
There is no built in "blinking" field format; EG something like this CSS demo: http://embed.plnkr.co/wEu87hHwAGETkHqctWFb
"Form Validation" in FileMaker has a number of different methods to grab user's attention, including:
1) Conditional formatting to make a field red outlined, red text, bold, etc... if it is not valid.
2) Forced validation via an OnRecordCommit script trigger, with a Show Custom Dialog prompt of what to fix before saving again.
3) Schema level validation that will not let a user continue unless the field is validated (pops filemaker system level dialog), do not allow override.
4) Show/Hide object when to show status messages, highlights, etc... for form validation.
There are also some radical custom applications as well that do their entire UI in a webviewer so they get full control over CSS and JS functionality. It's not really native though, so I'm not sure if it's recommended.
Why the requirement for blinking? If you had to create some sort of blinking effect, you could probably do so with "refresh object" inside of an "install ontimer script" script, global variable, and "hide object when" calculation.
EG this script:
If [ $$blinkcount >= 10 ] Set Variable [ $$blinkcount ; "" ] Set Variable [ $$blinkstate ; "" ] Exit Script End IfIf [ $$blinkstate <> "on" ] Set Variable [ $$blinkstate ; "on" ]Else Set Variable [ $$blinkstate ; "off" ]End IfSet Variable [ $$blinkcount ; $$blinkcount + 1 ]Refresh Object [ "blinkingobject" ]Install OnTimer Script [ "self" ; .3 seconds ]
If [ $$blinkcount >= 10 ]
Set Variable [ $$blinkcount ; "" ]
Set Variable [ $$blinkstate ; "" ]
Exit Script 
If [ $$blinkstate <> "on" ]
Set Variable [ $$blinkstate ; "on" ]Else
Set Variable [ $$blinkstate ; "off" ]
Set Variable [ $$blinkcount ; $$blinkcount + 1 ]
Refresh Object [ "blinkingobject" ]
Install OnTimer Script [ "self" ; .3 seconds ]
And this "hide object when" calculation on your named "blinkingobject"
$$blinkstate <> "on"
Aww, say it isn't so, Joe!
Just change the color of the text or background of the field and leave it at that. You don't want a user walking into your office and going all "postal" on you, do you?
"Need" is a relative term, but there's nothing like a blinking light to get attention, and if a reasonable method to do this had been developed, it would be a nice addition to my tool kit.
Specifically, I was considering this for my own use in my shop. I am a one man company, and since I wear a lot of hats I often don't sit down in front of the computer to actually "do something" for a couple days... I might reference some repair orders, maybe add a part or labor time, but it's a glancing blow so I can easily miss something (and occasionally do.) One part of my system that needs improvement is a way to track promises I make to people... send them an estimate, expect a vehicle drop-off at a particular time or call a customer when there's an opening, or any number of "to do" sorts of things that have escalating urgency as they get older.
Most days I'm on my feet, either on the phone, talking with a customer, or working on a vehicle most of the day, and I have my database running on two screens, on at the front desk and one in the shop. If something started blinking when it was past-due it would more likely get my attention from across the shop.
... besides, you've seen a NASA control room, there are blinking things all over the place! I want some of that!
I gather, by the way, that the answer is "no" nothing has changed from years ago (I recall asking the same question... wow, probably 20 years ago).
Before there was conditional formatting we used to play around with graphics in repeating container fields, which got me wondering if an animated GIF file would display in a container field. That would be one way to blink a background... but I assume this doesn't work.
You can indeed use a webviewer to run the code that I linked to earlier.
However, you used the term “field”, which I took as the literal meaning of filemaker’s field object, with the inherent abilities to enter data in there.
If you just need “something” flashing on the screen, then a webviewer may be fine.
The example I posted earlier will allow you to perform flashing actions by showing and hiding an object entirely.
