javascript - jquery back button to previous category in sortable gallery -


i have jquery portfolio gallery 4 categories sortable. when click on category portfolio rearranged on same page through jquery showing project in category. upon clicking specific project user can see project page/details. want add button on page when user viweing project can return category @ before.

i tired following creates button take me main portfolio page, not category browsing before.

function goback() { window.history.back(); }

this 1 of gallery page in case: http://goo.gl/jesnjd

not knowing of application's code, bit of shot in dark think know you're missing.

using history.back() take last page visited (a page visit recorded if url updated). if updating content in website jquery , not loading new page, browser's history doesn't record takes top page still.

what need change button code hide current project, , redisplay category page. cannot use history.back().

edit: if need more data correctly rebuild previous page, can either change url category page (not simple implement perhaps robust thing do), or store information page came from. if using cookies, save navigation there, add ref value query string when navigate project page.

category page:

<a href="/home/projectname?ref=categoryname">link project</a>

project page:

<a href="/home?category=categoryname">back button</a>

then use information reopen or resort categories.

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.
