javascript - Trying to call function on a dynamically generated object name -

-

i'm having issues calling function on object name determined dynamically. code below illustrates how code set up, , problem i'm having occurring in function called dosomethingelse().

var obj = function(){     this.test = this.objmgr(); };   obj.prototype.objmgr = function(){       var self = this;        function dosomething(){           //do processing seems unimportant particular prob            dosomethingelse();      }        function dosomethingelse(){            //the object need determined @ runtime, , therefore dynamic           var callfunconthis = 'subobj';            //how heck can call function on object referenced in callfunconthis           this[callfunconthis].a(); //doesn't work, refers dom window           self[callfunconthis].a(); //doesn't work, self refers obj           eval(callfunconthis).a(); //works, there better way?      }        var subobj = {           a:function(){           },           b:function(){           }      };        var subobj2 = {           a:function(){           },           b:function(){           }      };        dosomething();       return{          subobj:subobj,          subobj2:subobj2      }  };  var test = new obj();

subobj never assigned scope can reference. why eval() best solution. having said this, i'm looking @ 1 weird bit of code. can elaborate on little? feel there architectural problem.

also, since you're returning object contains subobj , subobj2, why not use scope.

function dosomethingelse(){     // ...     retobj[callfunconthis].a() }  var retobj = {'subobj': subobj, 'subobj2': subobj2};  dosomething();  return retobj;

c# - How to set Z index when using WPF DrawingContext? -

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

i need sort through array , sort each individual row in array in ascending order. doesn't seem going (surprise!) keep getting hit 2 errors: a2101: cannot add 2 relocatable labels , a2026: constant expected here's sort, makes sense me, think i'm still trying implement high-lvl language techniqes assembly. there way around not being able use relative values? (the array 7 rows 9 columns, btw). mov cx, 7; cx = number of rows outer: ; outer loop walk through rows push cx mov cx, 9 mov row, cx ;rows middle: ; middle-loop walk through columns push cx sub cx, 1 ;cx = cx-1 mov column, cx ;columns inner: ;inner loop - compare , exchange column values cmp marray[row*9 + column], marray[row*9 + column+1] xchg marray[row*9 + column+1], marray[row*9 + column] ; compare , exchange values marray table inc column loop inner pop cx loop mid...
