python解决js文件utf-8编码乱码问题(推荐)

html文件中引入js文件，显示乱码！

js文件为utf-8 编码(无bom)  ，此时只要将js文件转成utf-8 BOM编码就可以解决了

可以使用notepad++转码

也可以使用下面的python代码批量转码

# -*- coding:utf-8 -*- 
import os,sys 
import chardet 
def convert( filename, in_enc = "GBK", out_enc="UTF-8" ): 
  try: 
    print("convert " + filename) 
    f = open(filename,'rb') 
    content = f.read() 
    result = chardet.detect(content)#通过chardet.detect获取当前文件的编码格式串，返回类型为字典类型 
    print(result) 
    f.close() 
    coding = result.get('encoding')#获取encoding的值[编码格式] 
    if coding != 'UTF-8-SIG' and coding == 'utf-8':#文件格式如果是utf-8的时候，才进行转码 
      print(coding + " to "+ out_enc +"!") 
      new_content = content.decode(in_enc).encode(out_enc) 
      f = open(filename, 'wb') 
      f.write(new_content) 
      f.close() 
      print(" done") 
    else: 
      print(coding) 
  except IOError as e: 
  # except: 
    print(e) 
def explore(dir): 
  for root, dirs, files in os.walk(dir): 
    for file in files: 
      path = os.path.join(root, file) 
      convert(path) 
def main(dir): 
  if(os.path.isdir(dir)): 
    fpaths = [fpath for fpath in os.listdir(dir) if os.path.isfile(dir+"\\"+fpath) and fpath.endswith('.js')] 
    dpaths = [dpath for dpath in os.listdir(dir) if os.path.isdir(dir+"\\"+dpath)] 
    for f in fpaths: 
      convert(dir+"\\"+f,'utf-8','UTF-8-SIG') 
    for d in dpaths: 
      print(d) 
      main(dir+"\\"+d) 
if __name__ == "__main__": 
  main('目录')
