在Wordpress中的自定义小部件中使用jQuery动态添加输入字段

Question

如何在Wordpress中的自定义小部件中使用jQuery动态添加输入字段（下面的代码）？它包含一些PHP代码，我尝试了很多方法，无法让它工作：

from string import ascii_lowercase as lower, ascii_uppercase as upper
from string import digits, punctuation

# create a translation table which
#   makes the string lowercase and
#   replaces all digits and punctuation with spaces
TRANS = str.maketrans(
    lower + upper +           digits + punctuation,
    lower + lower + " " * len(digits + punctuation)
)

def get_word_list(filename):
    with open(filename) as inf:
        return inf.read().translate(TRANS).split()

words = get_word_list("mobydick.txt")
