Errors: Missing parenthesis after argument list

Errors: Missing parenthesis after argument list

信息

SyntaxError: missing ) after argument list

错误类型

SyntaxError.

哪里出错了?

调用函数时出错。例如，这可能是一个错字，缺少一个运算符或一个未转义的字符串。

示例

因为没有“+”运算符来连接字符串，JavaScript期望log函数的参数是正确的"PI: "。在这种情况下，应该用一个右括号来终止。

console.log('PI: ' Math.PI
// SyntaxError: missing ) after argument list

您可以log通过添加“ +”运算符来改正呼叫：

console.log('PI: ' + Math.PI
// "PI: 3.141592653589793"
