You can re-activate the actions by adding   this delegateEvents        Re-activates the events for all the buttons   If you add it to the render function of a backbone js view  then you can use event preventDefault   as required

You would have to unbind the event and either rebind to a separate event that does not preventDefault or just call the default event yourself later in the method after unbinding  There is no magical event cancelled false   As requested      form   submit  function ev             ev preventDefault                later you decide you want to submit            this  unbind  submit   submit

Either you do what redsquare proposes with this code   function preventDefault e        e preventDefault         form   bind  submit   preventDefault       later  now switching back    form foo   unbind  submit   preventDefault     Or you assign a form attribute whenever submission is allowed  Something like this   function preventDefault e        if  event currentTarget allowDefault            return            e preventDefault         form   bind  submit   preventDefault       later  now allowing submissions on the form    form foo   get 0  allowDefault   true

I had a similar problem recently  I had a form and PHP function that to be run once the form is submitted  However  I needed to run a javascript first             This variable is used in order to determine if we already did our js fun         var window alreadyClicked    quot NO quot             quot form not   press   quot   bind  quot submit quot   function e                  Check if we already run js part             if window alreadyClicked     quot NO quot                       Prevent page refresh                 e preventDefault                       Change variable value so next time we submit the form the js wont run                 window alreadyClicked    quot YES quot                     Here is your actual js you need to run before doing the php part                 xxxxxxxxxx                     Submit the form again but since we changed the value of our variable js wont be run and page can reload  and php can do whatever you told it to                     quot form not   press   quot   submit

With async actions  timers  ajax  you can override the property isDefaultPrevented like this      a   click function evt     e preventDefault          in async handler  ajax timer  do these actions    setTimeout function           override prevented flag to prevent jquery from discarding event     evt isDefaultPrevented   function    return false           retrigger with the exactly same event data       this  trigger evt        1000       This is most complete way of retriggering the event with the exactly same data
