[英]Get the name of the function from inside the function
是否可以从函数内部获取函数名称?
例:
function myFunction() {
// console.log the name of this function without knowing/specifying what the name is
// otherwise console.log('myFunction was called'); is
// more obvious (and better supported) than console.log(myFunction.name);
// console.log(arguments.callee.name); works but not in strict mode and is deprecated
}
参考:
Function.name
arguments.callee的
更新:
从评论和答案看来,这一点已被完全遗漏了。
我修改了示例以使其更加清晰。
更新2:
似乎仍然有歧义...这是调试过程的示例:
function one() {
console.log(arguments.callee.name + ' was called'); // one was called
// reset of the code
}
function two() {
console.log(arguments.callee.name + ' was called'); // two was called
// reset of the code
}
function three() {
console.log(arguments.callee.name + ' was called'); // three was called
// reset of the code
}
function four() {
console.log(arguments.callee.name + ' was called'); // four was called
// reset of the code
}
function five() {
console.log(arguments.callee.name + ' was called'); // five was called
// reset of the code
}
arguments.callee.name
已弃用,在严格模式下不可用。
我正在寻找一种不建议弃用且在严格模式下有效的方法。
