Question

编写一个函数，以神奇宝贝的名字作为参数并显示宠物小精灵的信息
编写一个以宠物小精灵的名字作为参数的函数，然后找出所有的宠物小精灵在其“ next_evolution”字段中都具有该名称。
编写一个以“弱点”为输入并给出名称的函数有这种弱点的所有宠物小精灵。（检查数据集）。

它没有显示任何错误，也没有找到解决方案……我需要解决这个问题，我是初学者，所以详细的逻辑或代码将对您有帮助

DetailOfPokemon(name, goPokemon)

Answer 1

var findname = window.prompt('Enter the name of Pokemon')的位置不正确。您将goPokemon.pokemon[x].name与findname进行比较，而findname尚未定义。

函数JSON.stringify()将对象转换为json字符串（可能更容易显示信息）。

顺便说一句，如果您不需要else指令，请不要编写它。
