问题 Strict and non-strict code can be mixed. But you can't use caller even if the call to it is not in strict code. Does anybody know any workaround? I tried this: (function strict(){ "use strict"; nonStrict();//ok nonStrictCaller();//error :( })(); function nonStrict(){ return 011;//Octal literals are not allowed in strict mode } function nonStrictCaller(){ return nonStrictCaller.caller; } 回答1: Here's an evil hack that only works in V8.

问题 I don't find anything about my question here on MDC or the ECMAscript specifications. Probably somebody knows a more 'hacky' way to solve this. I'm calling "use strict" on every javascript file in my environment. All my files start like this (function(win, doc, undef) { "use strict"; // code & functions }(window, window.document)); Now, I have a custom function which handles errors. That functions uses the .caller property to provide a context stack trace . Looks like this: var chain =

问题 I'm trying to build a script to generate ALTER TABLE queries so that across whole schemas, columns are adjusted to be compatible with MySQL strict-mode..

Any tips / things I've missed out / things

In Edition 3, the variable and lexical environments of the caller of an indirect eval was used as the environments for the eval code. However, in Opera, this expression results in undefined : (function(){'use strict'; return (0 || eval)(

问题 There's an old trick (that I learned on SO) to catch calling a constructor as a function, i.e. forgetting the new keyword. The following, or something like, it goes in each constructor at the top. if (!(this instanceof arguments.callee)) { throw Error("Constructor called as a function"); } What are the alternatives when you need to "use strict"; ? Can its generic nature be retained? Or do we have to use the name of the constructor in place of arguments.callee ? 回答1: arguments.callee itself is
