在JavaScript中,string.fromcharcode 不是一个标准的方法,因此当你尝试使用它时会遇到错误:“string.fromcharcode is not a function”。这是因为JavaScript中正确的方法名是 String.fromCharCode,而不是 string.fromcharcode。以下是对这个问题的详细解答: 解释string.fromcharcode不是JavaScript标准方法: string.fromcha...

WhenfromCharCode()has only one parameter, it is very much like the reverse operation ofcharCodeAt(). they are a pair of good partners. We often see them in the kata about the shift encryption. See an example: functiondecode(str){varchars=str.split("");for(vari=0;i<chars.length;i++...
