javascript - Uncaught typeerror: Object #<object> has no method 'method' -

so here's object 'playerturnobj' function playerturnobj(set_turn) { this.playerturn=set_turn; function setturn(turntoset) { this.playerturn=turntoset; } function getturn() { return this.playerturn; } } and here i'm doing it var turn = new playerturnobj(); turn.setturn(1); so try make script setturn() method in playerturnobj() save 'turn' in game i'm making. problem is, not turn.setturn(1); part because keep getting error above what doing wrong? searched, not find exact answer question. this not way javascript works. "constructor" function contains inline functions not visible outside of scope of playerturnobj . variable turn not have method setturn defined, error message states correctly. want this: function playerturnobj(set_turn) { this.playerturn=set_turn; } playerturnobj.prototype = { setturn: function(turntoset) { this.playerturn=turntoset; }, getturn: func

jquery - Is inline/block Javascript executed before document-ready? -

assuming 1 has inline javascript code in html document (the body example), piece of javascript executed before jquery document-ready code? for example, following safe? ... <body> <script type="text/javascript"> var myvar = 2; </script> ... </body> ... $(document).ready(function() { alert('my var = ' + myvar); } if not, how can make safe knowing myvar defined in inline/block code? yes, above code safe. inline js executed encountered while document being parsed top bottom. document ready handler executed when document ready (obviously), , won't ready until whole document has been parsed including inline scripts. note don't need document ready handler if include code wraps last thing in document body, because @ point not other inline js have executed of document elements have been added dom , accessible js.

spring - Generic DAO - "Never go full generic!" -

ive seen allot of usages of generic dao on internet. gotta love it: public interface genericdao <t, pk extends serializable> {} public class genericdaohibernateimpl <t, pk extends serializable> implements genericdao<t, pk> a new class appeared? no problem: public interface newclassdao extends genericdao<newclass, long> and we're set. now, how bad if go "full-generic" , like: public interface fullgenericdao public class fullgenericdaohibernateimpl now can use 1 dao (of object casting!) a new class appeared again? no problem: newclassapperedagain newclassappeared = (newclassapperedagain) fullgenericdao.getitembyid(20, newclassapperedagain.class); two questions comes mind: 1) possible go "full-generic" , create such dao? mean dont see why not passing every method of dao classname , casting neccessary? save(object,classname); delete(object,classname); etc.. 2) cons (i'm sure there are) of such practice?

performance - R: Why is the [[ ]] approach for subsetting a list faster than using $? -

i've been working on few projects have required me lot of list subsetting , while profiling code realised object[["namehere"]] approach subsetting lists faster object$namehere approach. as example if create list named components: a.long.list <- as.list(rep(1:1000)) names(a.long.list) <- paste0("something",1:1000) why this: system.time ( (i in 1:10000) { a.long.list[["something997"]] } ) user system elapsed 0.15 0.00 0.16 faster this: system.time ( (i in 1:10000) { a.long.list$something997 } ) user system elapsed 0.23 0.00 0.23 my question whether behaviour true universally , should avoid $ subset wherever possible or efficient choice depend on other factors? function [[ first goes through elements trying exact match, then tries partial match. $ function tries both exact , partial match on each element in turn. if execute: system.time ( (i in 1:10000) { a.long.list[[
