Dont ask confirm if user submit the form


I am using following JavaScript code to warn a user if he tries to redirect to another page without submitting the form.

window.onbeforeunload = function() {
   return 'Are you sure that you want to leave this page?';
};

This is working fine.But my problem is when user trying to submit the form using submit button confirm box will be appear. I don't want to ask the confirm if user submitting the form,otherwise I want to ask confirm. How is it possible?


Solution

  • maintain a state variable. when user click submit button set state to userSubmitted=True;
    state variable may include a global variable or hidden control.

    var userSubmitted=false;
    
    $('form').submit(function() {
    userSubmitted = true;
    });
    

    then check like this

    window.onbeforeunload = function() {
        if(!userSubmitted)
            return 'Are you sure that you want to leave this page?';
    };
    

    PS : cross check for onbeforunload compatibility for cross browser.
