推荐答案
在Javascript控制台中记录的对象是实时,因此展开它们会显示对象的当前内容。第一行显示当您第一次调用 console.log()
时, outputList
为空。但是稍后会在数组中添加一些内容,当您通过单击显示三角形展开对象时,您会看到更新的值。
Objects logged in the Javascript console are "live", so expanding them shows the current contents of the object. The first line shows that the outputList
was empty when you first called console.log()
. But something was added to the array later, and when you expanded the object by clicking on the disclosure triangle, you see the updated value.
