| // how to pass arbitrary "this" object for eval'ed script? |
| |
| var obj = { foo: 44 }; |
| |
| // the following won't work. eval.apply is indirect eval call |
| // and so 'this' will be global object always! So, this |
| // line will print 'undefined' |
| eval.apply(obj, [ " print(this.foo)" ]); |
| |
| obj.myEval = eval; |
| |
| // still won't work - still indirect 'eval' call! |
| // still undefined is printed! |
| obj.myEval("print(this.foo)"); |
| |
| function func(code) { |
| eval(code); |
| } |
| |
| // eval called inside func and so get's func's "this" as it's "this"! |
| // So, 44 is printed |
| |
| func.apply(obj, [ "print(this.foo)" ]); |
