第十八节

一 、js正则

test - 判断是否符合规定的正则

exec - 获取匹配的数据

test

rep = /\d+/;
/\d+/
rep.te
undefined
rep.test("dgdf343dgffddsf332")
true
rep.test("dsfssgd")
false
获取字符串中的数字
rep = /^\d+$/
/^\d+$/
rep
/^\d+$/
rep.test("123")
true
rep.test("123df")
false
开头结尾之匹配数字

 exec

rep = /\d+/
/\d+/
str = "dsfsd_ss235_324dfgd"
"dsfsd_ss235_324dfgd"
rep.exec(str)
["235", index: 8, input: "dsfsd_ss235_324dfgd"]
获取字符串的的数字

 

text = "Java is more fun than JavaScript and JavaBeans"
"Java is more fun than JavaScript and JavaBeans"
var pattern = /\bJava\w*\b/
undefined
pattern.exec(text)
["Java", index: 0, input: "Java is more fun than JavaScript and JavaBeans"]

# "\b"可以识别字符串的的空格,以字符串为分割;"\w"可以识别所有,不限数据类型;"\d"只识别数字。
获取一整句字符串中的指定字符
text = "JavaScript is more fun than Java and JavaBeans"
"JavaScript is more fun than Java and JavaBeans"
var pattern = /\bJava(\w*)\b/
undefined
pattern.exec(text)
(2) ["JavaScript", "Script", index: 0, input: "JavaScript is more fun than Java and JavaBeans"]

# 匹配Java开头的JavaScript,同时又对Script做了分离,以字符串列表的行书返回。
整体取出再分离

 

正则表达式

/..../  用语定义正则表达式

/.../g  匹配整行

/.../i  不区分大小写

/.../m  多行匹配

var pattern = /\bJava\w*\b/gm 整行匹配

# 单行匹配

var pattern = /\bJava\w*\b/g
undefined
pattern.exec(text)
["JavaScript", index: 0, input: "JavaScript is more fun than Java and JavaBeans"]
pattern.exec(text)
["Java", index: 28, input: "JavaScript is more fun than Java and JavaBeans"]
pattern.exec(text)
["JavaBeans", index: 37, input: "JavaScript is more fun than Java and JavaBeans"]
pattern.exec(text)

# 多行匹配

var pattern = /^Java(\w*)/g
undefined
pattern.exec(text)
(2) ["JavaScript", "Script", index: 0, input: "JavaScript is more fun than ↵Java and JavaBeans"]
pattern.exec(text)
null
var pattern = /^Java(\w*)/gm
undefined
pattern.exec(text)
(2) ["JavaScript", "Script", index: 0, input: "JavaScript is more fun than ↵Java and JavaBeans"]
pattern.exec(text)
(2) ["Java", "", index: 29, input: "JavaScript is more fun than ↵Java and JavaBeans"]
pattern.exec(text)
null
View Code

 

二、组件

BootStrap

  - css

  - js

easyUI

  - css

  - js

jQueryUI

  - css

  - js

 

1.js验证

 

 

 

 

 # 创建django项目

django-admin startproject mysite

# mysite目录结构

mysite

  - mysite    # 对整个程序进行配置

    - settings   # 配置文件 # 注销csrf;添加templates路径;在文件尾配置static路径,STATICFILES_DIRS;

    - url     # url对应关系

    - wsgi    # 寻租wsgi规范,uwsgi + nginx

      wsgi遵循很多规则,这些规则的本质是帮助django创建socket

  - manager.py  #管理django程序:

          - python manage.py

          - python manage.py startapp xx

          # python自己的orm,管理自己的数据库。生成自己的类

          - python manage.py makemigrations

          - python manage.py migrate

 # 在django项目中创建app

python manager.py startapp crm
