javascript - Function toString() not working -


i use javascript in qml application , want insert code of function string:

function test(parameter) {     console.log("something do!"); } ... function otherfunction(otherparam) {     console.log("output: "+test.tostring()); }

all print following:

"output: function() { [code] }"

instead of desired string: "output: function() { console.log("something do!"); }"

p.s.: remember code worked somewhere during migrating qt 5.2 qt 5.4 , fixing cmake scripts, broke.

what problem here?

tostring applied function implementation detail. per ecma-262, should works expect, evidently, implemented, doesn't :( in case, standard allows work differently between implementations.

you depended on implementation detail, changed implementations, shouldn't surprised.

if need store code, can generate function eval-uating string, , add code property of function.

according 5th edition of ecma-262, section 15.3.4.2, function.prototype.tostring() should return implementation-defined rendition having syntax of functiondeclaration. perhaps qt's js engine here exhibits nonstandard behavior.

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.
