使用以下javascript代码动态添加标签索引。

def t1():
    print(1)

def t2():
    print(2)

def t3():
    print(3)

def t4():
    print(4)

def t5():
    print(5)

def t6():
    print(6)

# put the functions in a list
functions = [t1, t2, t3, t4, t5, t6]

def go(functions):
    # .format(variable) replaces {} with the value of variable (string formatting)
    number_of_funcs = len(functions)
    greeting = "Type a number from 1 to {}: ".format(number_of_funcs)
    selected = input(greeting)
    try:
        # index to start from
        index = int(selected) - 1
    except ValueError:
        # check if the user wrote a number (exception handling)
        print('Invalid input. Not a number')
        return
    if index > number_of_funcs - 1 or index < 0:
        msg = 'Invalid input. Consider a number from 1 to {}'.format(number_of_funcs)
        print(msg)
        return
    # iterate through the functions of the list
    # starting from the index specified (list slicing)
    for f in functions[index:]:
        f()

while(True):
    # infinite loop. press Ctrl+C to abort
    go(functions)

如何动态地通过JavaScript为锚标签添加tab-index？
