javascript - 扩展 json 对象 javascript

Question

javascript代码：

window.mybooks={"books": [{"name":"book one","author":"Samuel Peter"},{"name":"book two","author":"Samuel Anderson"}]};

如何将新书添加到 window.mybooks ？

{"name":"book three","author":"Samuel Abelson"}

更新：

奇怪，很多相同的答案，对我不起作用……是什么原因造成的？

我确实发现该对象已生成，可能是错误的。它看起来像这样：

window.mybooks={"books": [{"name":"book one","author":"Samuel Peter"},{"name":"book two","author":"Samuel Anderson"},]};

任何提示如何纠正它和mayabe然后推送会起作用吗？

var newBook = {"name":"book three","author":"Samuel Abelson"};
mybooks.books.push(newBook );

如果您不在窗口上下文中，则显式使用window.mybooks.books.push(newBook);

var newBook = {"name":"book three","author":"Samuel Abelson"};
mybooks.books.push(newBook);

试试这个应该可以的。利用Javascript Array.push
