javascript - How to maintain reference to an instance, when using the setTimeout callback? -

how maintain reference instance, when using settimeout callback? e.g: in viewmodel (using knockout) var myvm = function () { this.myfunc = function () { settimeout("this.mycallback()", 2000); }; this.mycallback = function() { this.myobservable(true); } } this fails. you can add private field : var myvm = function () { var self = this; this.myfunc = function () { settimeout(self.mycallback, 2000); }; this.mycallback = function() { self.myobservable(true); } } var vm = new myvm(); have @ rp niemeyer's answer . i hope helps.

vim - What is the use case of marks? -

-
both sublime text 2 , vim have feature called marks . however, i've not been able find use case it. feels can can done other things, better. so question is: use case of marks? if mean marking text lines in vim , use quite bit. for example, if want go @ else, can use ma mark current line a , go check out else in file, return simple 'a . similarly, if want delete unknown number of lines between current position , somewhere else, use ma , go "somewhere else, , use d'a . there many more things can them (such changing text between current position , mark), 2 common ones use (and use them lot).
