这可能是一个全新的问题，但我很难过。 如果我有这样的功能as： 函数DoSomething（strVarName）{ ..... } 我称之为： DoSomething（''myVarName''）; 在函数内部，怎么做我为名为myVarName的变量赋值了一个值 （即名称为strVarName值的变量）？ 谢谢！ Russ

Hi, This may be a totally newbie question, but I''m stumped. If I have a function such as: function DoSomething(strVarName) { ..... } and I call it like so: DoSomething(''myVarName''); Inside the function, how do I assign a value to the variable named myVarName (i.e. the variable whose name is the value of strVarName)? Thanks! Russ

window [strVarName] =某个值; Mi ck

window[strVarName]=some value; Mick

不，不要'' T。 'window''可能是许多 案例中对全局对象的引用，但并非全部。改为使用对全局对象的引用： var MyVarName = ...; var _global = this; 函数doSomething（strVarName） { ... _global [strVarName] ... } doSomething（''myVarName''）; 如果你担心新的全球`_global'会破坏你的全球 命名空间，你也可以这样做 var MyVarName = ...; 函数doSomething（strVarName） { ... doSomething._global [strVarName] ... } doSomething._global = this; doSomething（''myVarName''）; PointedEars

No, don''t. `window'' may be a reference to the Global Object in many cases, but not in all. Use a reference to the Global Object instead: var MyVarName = ...; var _global = this; function doSomething(strVarName) { ... _global[strVarName] ... } doSomething(''myVarName''); If you are concerned that the new global `_global'' spoils your global namespace, you can instead also do var MyVarName = ...; function doSomething(strVarName) { ... doSomething._global[strVarName] ... } doSomething._global = this; doSomething(''myVarName''); PointedEars
