I´m developing for web and my application use some alerts to show error messages but in firefox 4 if I show the alert more than one time, the option for blocking repetitive alert dialogs will appear, but if I check the option, I can not continue to do the next action.
Can you tell me how to hide the option in alert ? Is there any possibility with javascript?
No, that’s the user’s option not yours.
Edit: You can show error messages in a unique way using JQuery UI’s dialog widget. This is not a standard popup box and is a nice way to display the error.
Another alternative is to have a div that you display errors in and show/hide it. This is less distracting since it shows all the errors at once.
