via jquery's $.getscript method, can give included script dom id? so generated code should be: <script type="text/javascript" id="xxxxxx" src="..."></script> i know document.write line myself, $.getscript must there reason right? (cross browser compatibility, etc?) i think has maybe been answered/discussed before here: why call $.getscript instead of using <script> tag directly? . getscript allows dynamically load script in situations it's either desirable delay loading of script, in situations want status callback on when script has been loaded or in situations couldn't use script tag. getscript has downsides in it's subject same-origin policy whereas script tag not. if have seen other web pages put id on script tag (smugmug.com), i've seen flagged non-standard when testing standard's compliance. seems work , used others, i'm guessing isn't standard.

i have code self.text = [nsstring stringwithutf8string:(char *)sqlite_column_text(init_statement, 0)]; i'm wondering why use stringwithutf8string: , char * stuff, instead of directly using nsstring here? presumably sqlite library not returning nsstring s, being c library knows nothing of objective c.

i know questions similar have been asked, have been searching through internet , can't seem find i'm looking for. the common answer put in controller. liked particular solution stackoverflow had sessioncontroller , nonsessioncontroller , both extending main controller sessioncontroller checking if user logged in before dispatch. does mean controller this? class sessioncontroller { ... function view() { //view thread stuff } function post() { if loggedin { //post thread stuff } } { in situation, looks nonsessioncontroller useless, , model used when every action controller handles either strictly users or non-users, unlike forum example. so guess question is, general concept of controller above efficient way of dealing login checks when using mvc? i think idea have 1 controller checks session , login, , 1 doesn't. i put login check in constructor of session controller wa...

i'm implementing lazy drawing of overlays based on user's current viewing rectangle. viewing rectangle gets initialized based on dimensions of mapview follows: rect viewrectangle = new rect(0, 0, mapview.getwidth(), mapview.getheight()); through debugging, width , height of mapview remain constant (except when there's orientation change) except initial creation of mapview dimensions (width , height) zero. unfortunately, despite attempts @ holding off initialization until of other ui components have been created, can't seem find proper place creation of viewing rectangle. not want place initialization within drawing of overlays because seems theoretically inefficient (with allocation overhead , potentially triggering garbage collection) create temporary objects every lazy-drawing call (triggered zooming, panning, , restful data refreshes). is there listener gets triggered when dimensions of mapview changed 0 state? i've tried multitude of different search...

can me understand get & set ? why needed? can make public variable. warning : assuming know object-oriented programming . what are properties? properties language elements allow avoid repetitive getxyz() accessors , setxyz() mutators techniques found in other languages, java. why exist? they aim solve following problems: saying get , set in beginning of every access or mutation of value annoying , distracting. in java, say: class person { private int _age; public void setage(int value) { /*check value first, set _age*/ } public int getage() { return this._age; } } and consistently say: if (person.getage() > blah || person.getage() < 10) { person.setage(5); } after while, get , set become rather annoying. providing direct access actual variable breaks encapsulation, that's not option. how used? they used just variables . read/write them variables. how created? they created methods . define pair of meth...
