This is not a direct answer for the question but it may help someone  My point is you only  call preventDefault   based on some conditions as there is no point of having an event if you call preventDefault   for all the cases  So having if conditions and calling preventDefault   only when the condition s satisfied will work the function in usual way for the other cases      btnEdit   click function e        var status     this  closest  tr   find  td   eq 3  html   trim       var tripId     this  attr  tripId       if  status     Completed           e preventDefault         alert  quot You can t edit completed reservations quot        else if  tripId               e preventDefault        alert  quot You can t edit a reservation which is already attached to a trip quot          else it will continue as usual

There is no opposite method of event preventDefault   to understand why you first have to look into what event preventDefault   does when you call it   Underneath the hood  the functionality for preventDefault is essentially calling a return false which halts any further execution  If you   re familiar with the old ways of Javascript  it was once in fashion to use return false for canceling events on things like form submits and buttons using return true  before jQuery was even around    As you probably might have already worked out based on the simple explanation above  the opposite of event preventDefault   is nothing  You just don   t prevent the event  by default the browser will allow the event if you are not preventing it   See below for an explanation     function    window  document  undefined            function                By default deny the submit         var allowSubmit   false               someform   on  submit   function event                 if   allowSubmit                    event preventDefault                        Your code logic in here  maybe form validation or something                     Then you set allowSubmit to true so this code is bypassed                  allowSubmit   true                                         jQuery  window  document     In the code above you will notice we are checking if allowSubmit is false  This means we will prevent our form from submitting using event preventDefault and then we will do some validation logic and if we are happy  set allowSubmit to true   This is really the only effective method of doing the opposite of event preventDefault       you can also try removing events as well which essentially would achieve the same thing

As per commented by  Prescott  the opposite of   evt preventDefault      Could be     Essentially equating to  do default   since we re no longer preventing it   Otherwise I m inclined to point you to the answers provided by another comments and answers   How to unbind a listener that is calling event preventDefault    using jQuery    How to reenable event preventDefault   Note that the second one has been accepted with an example solution  given by redsquare  posted here for a direct solution in case this isn t closed as duplicate       form   submit  function ev         ev preventDefault           later you decide you want to submit        this  unbind  submit   submit

jquery on   could be another solution to this  escpacially when it comes to the use of namespaces   jquery on   is just the current way of binding events   instead of bind      off   is to unbind these  and when you use a namespace  you can add and remove multiple different events      selector   on  submit my-namespace   function  event           prevent the event     event preventDefault           cache the selector     var  this     this        if   my condition is true               when  my condition is true  is met  the binding is removed and the event is triggered again           this off  submit my-namespace   trigger  submit                now with the use of namespace  you could add multiple of these events and are able to remove those  depending on your needs   while submit might not be the best example  this might come in handy on a click or keypress or whatever

I supose the  opposite  would be to simulate an event  You could use  createEvent    Following Mozilla s example   function simulateClick       var evt   document createEvent  MouseEvents      evt initMouseEvent  click   true  true  window      0  0  0  0  0  false  false  false  false  0  null     var cb   document getElementById  checkbox       var cancelled    cb dispatchEvent evt     if cancelled           A handler called preventDefault     alert  cancelled        else          None of the handlers called preventDefault     alert  not cancelled            Ref  document createEvent    jQuery has  trigger   so you can trigger events on elements -- sometimes useful       foo   bind  click   function           alert   this  text              foo   trigger  click
