javascript - 如何从函数内部调用函数？

Question

如何将函数放入函数中？

do_something(){
    alert('do something');
}

also_do_something = function(){
    alert('also do something');
};

inp.onclick = function(){
    do_something();

    // this don't work
    also_do_something;
};

Answer 1

要调用函数，必须添加括号:

inp.onclick = function(){
    do_something();

    also_do_something();
};
