在JS中我们经常会会用到,获取一个标签的id var aId=document.getElementById("id") 现在虽然有getElementsByClassName这个方法,但是这个方法再ie6下兼容性存在问题,所以保险起见还是封一个获取class的库 首先先看库 /** * Created by asus on 2016/12/4 By dirk_jian. */ function getByclass(oParent,sClass){ var aEle=oParent.
一开始使用了beautifulSoup的get_text()进行字符串的提取,后来一直提取失败,并提示错误为TypeError: 'NoneType' object is not callable 返回了none类型,可能是对Span标签内容的提取产生错误,于是采用name.string进行字符的提取,成功. # -*- coding: utf-8 -*- """ Created on Wed Jan 11 17:21:54 2017 @author: PE-Monitor
