jquery - Form validation with click event -


i have form validation:

       <form role="form" method="post" action="" >             <input type="password" class="form-control top-buffer-sm" placeholder="password" name="password" required autofocus></input>             <input type="email" class="form-control top-buffer-sm" placeholder="email" name="email" required autofocus></input> <div class="modal-footer">     <button id="createuser" type="submit" class="btn btn-primary">create</button>     <button type="button" class="btn btn-default" data-dismiss="modal">close</button> </div>

my submit button has id , need other functionality before submit form:

      $('#createuser').click(function(){             //check see if validation passed              //do custom stuff              //now make ajax call               $.ajax();         });

but if form not valid, ajax call still being made, of course resulting in server error. how check see if form passed validation when click submit button? thanks

why not list submit event on form?

<form role="form" method="post" action="" id="myform">

then:

$('#myform').on('submit', function(event) {   // prevent form submission on click   event.preventdefault();    // write code determins if form valid.   // `this` refers form.   if (formisvalidcondition) {     // ajax call here   } else {     // return response user     return false;   } });

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
