jquery - Retrieve certain object from an array and act upon retrieval -

i hadn't received concrete answer previous thread: retrieve "id" array in jquery

so i'll try explain in more detail , show did.

i'm working on small game , have several obstacles in array so:

obstacles = [ { id: '#car' }, { id: '#house' }, { id: '#door' }, ]; 

in second part of code, have:

jquery:

 $('#alert').hide();  (index in obstacles) {          object = $(obstacles[index]["id"]);       obj_left = object.position().left + parseint(object.css("margin-left"));     obj_top = object.position().top + parseint(object.css("margin-top"));          if ((((posx > (obj_left - me.width() / 2)) &&        (posx < (obj_left + object.width() + me.width() / 2)))) &&       (posy > (obj_top - me.height() / 2)) &&       (posy < (obj_top + object.height() + me.height() / 2))) {               // cannot walk              return false;         }     // it's starts ugly here.     if (object == '#car') {     $('#character').hide();       }     if (object == '#door') {     $('#noenter-alert').show();     }     }     // can walk again     return true && $('#character[).show(), $('#noenter-alert').hide();    } 

html:

<div id="alert">//...</div> <div id="character"></div> <div class="door" id="door"></div> <div class="house" id="house"></div> <div class="car" id="car"></div> 

i tested out , worked great. instead of displaying alert every obstacle, want retrieve value of obstacle (i.e: if player hits car, hide player or if player hits door output "you may not enter!").

hope i've been straightforward , have provided fair amount of code.

and here's link tutorial followed: http://blog.oscarliang.net/pokemon-online-game-theme-tutorial/

thanks! apologize repost hope can fix mess.

alert should in if condition

if ((((posx > (obj_left - me.width() / 2)) && (posx < (obj_left + object.width() + me.width() / 2)))) && (posy > (obj_top - me.height() / 2)) && (posy < (obj_top + object.height() + me.height() / 2))) {  //here need put alert         alert(object+'is here')         return false;     }
