AI代码解释 for(varkin{a:1,b:2}){alert(k);}alert(k);// 尽管循环已经结束但变量k依然在当前作用域 我们来看看一下,我们声明数据的时候到底都发现了什么细节。 数据声明 如果变量与执行上下文相关,那变量自己应该知道它的数据存储在哪里,并且知道如何访问。这种机制称为变量对象(variable object)。 变量对象(...
for ( var k in {a:1,b:2} ) { alert(k); } alert(k); //尽管循环已经结束但变量k依然在当前作用域 既然变量和执行上下文相关,那变量自己应该知道它数据存储在哪里(不同上下文,可能有名字相同变量),并且知道如何访问。这种机制称为变量对象(variable object)。 变量对象(缩写为VO)是一个与执行上下文相关...
