Inline `++` in Javascript not working

Question

Astonished to find out that a line like this :

$('#TextBox').val(parseInt($('#TextBox').val())++ );

Will not work !

I've done some tests, it plays out to the conclusion that the inline ++ doesn't work (in Javascript as a whole ? Or simply in my example ?).

Here's a test with three pieces of code, it seems that ++ is ok with a variable but not inline.

So, no inline ++ for us in Javascript?

Answer 1

There's nothing particular to jQuery about this. ++ increments a variable. You are trying to increment the return value of a function call.
