动态变量名称 [英] Dynamic variable names
问题描述
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！

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;

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''）;

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'');
