Check if any form fields have changed upon saving asp.net c# -


i've got large .net form hundreds of input fields, users navigate off form page without saving, what's best way check if field value has changed when try navigate away? c# function or javascript?

don't take control out of users hand :-)

ask him on exit, if wants save changes. maybe did changes mistake, don't want save.

you can achieve javascript/jquery. like:

$(document).ready(function() {     formmodified=0;     $('form *').change(function(){         formmodified=1;     });     window.onbeforeunload = confirmexit;     function confirmexit() {         if (formmodified == 1) {             return "new information not saved. wish leave page?";         }     }     $("input[name='commit']").click(function() {         formmodified = 0;     }); });

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.
