Question

I have multiple (10) if statemnets stacked in a function, and need something like this:

$len=$("#user").val().length;
   if($len == 0) { do something and then - stop, exit, break ... whatever)

So, if $len is 0 – do something and – dont check anything more. Just exit from the execution.

Answer 1

You can use return statement but it will take the execution control at end of function and skip all the statements between. or use if-else block or use switch.

if($len == 0) {

   do something and then - stop, exit, break ... whatever
   return;
)

Use if-else

if($len == 0) {

   do something and then - stop, exit, break ... whatever
   return;
)
else
if($len == 1) {

   do something and then - stop, exit, break ... whatever
   return;
)
//repeate if else

Using switch

switch($len)
{
 case 0:
  //execute code block 1
  break;
case 1:
  //execute code block 1
  break;
case 2:
  //execute code block 2
  break;
default:
  code to be executed if n is different from case 1 and 2
}
