How to disable prevent this page from creating additional dialogs

Question

I m developing a web app that utilises JavaScript alert   and confirm   dialogue boxes   How can I stop Chrome from showing this checkbox     Is there a setting I can modify   I know I could modify the source code  but I d like it so that Chrome could still auto-update   I don t need to worry about other browsers since the app only runs in Chrome   I have admin access to the  Windows  machines that run the app

This is what I ended up doing  since we have a web app that has multiple users that are not under our control     DannyBeckett I know this isn t an exact answer to your question  but the people that are looking at your question might be helped by this   You can at least detect if they are not seeing the dialogs   There are few things you most likely want to change like the time to display  or what you are actually displaying   Remember this will only notify the user that they are have managed to click that little checkbox   window nativeAlert   window alert  window alert   function  message        var timeBefore   new Date        var confirmBool   nativeAlert message       var timeAfter   new Date        if   timeAfter - timeBefore   lt  350            MySpecialDialog  You have alerts turned off             window nativeConfirm   window confirm  window confirm   function  message        var timeBefore   new Date        var confirmBool   nativeConfirm message       var timeAfter   new Date        if   timeAfter - timeBefore   lt  350            MySpecialDialog  You have confirms turned off              return confirmBool      Obviously I have set the time to 3 5 milliseconds   But after some testing we were only able to click or close the dialogs in about 5 milliseconds plus

I know everybody is ethically against this  but I understand there are reasons of practical joking where this is desired   I think Chrome took a solid stance on this by enforcing a mandatory one second separation time between alert messages   This gives the visitor just enough time to close the page or refresh if they re stuck on an annoying prank site   So to answer your question  it s all a matter of timing   If you alert more than once per second  Chrome will create that checkbox   Here s a simple example of a workaround   var countdown   99  function annoy        if countdown gt 0           alert countdown   bottles of beer on the wall    countdown   bottles of beer  Take one down  pass it around     countdown-1    bottles of beer on the wall             countdown--              Time must always be 1000 milliseconds  999 or less causes the checkbox to appear         setTimeout function                annoy               1000               Don t alert right away or Chrome will catch you setTimeout function        annoy       1000

You should better use jquery-confirm  rather than trying to remove that checkbox      confirm       title   Confirm        content   Are you sure you want to refund invoice         confirm  function             do something             cancel  function             do something

You should let the user do that if they want  and you can t stop them anyway    Your problem is that you need to know that they have and then assume that they mean OK  not cancel   Replace confirm x  with myConfirm x    function myConfirm message        var start   Number new Date         var result   confirm message       var end   Number new Date         return  end lt  start 10   result  true

You can t  It s a browser feature there to prevent sites from showing hundreds of alerts to prevent you from leaving   You can  however  look into modal popups like jQuery UI Dialog  These are javascript alert boxes that show a custom dialog  They don t use the default alert   function and therefore  bypass the issue you re running into completely   I ve found that an apps that has a lot of message boxes and confirms has a much better user experience if you use custom dialogs instead of the default alerts and confirms
