Markdown及扩展
Markdown 是一种轻量级标记语言,它允许人们使用易读易写的纯文本格式编写文档,然后转换成格式丰富的HTML页面。 —— <a href="https://zh.wikipedia.org/wiki/Markdown" target="_blank"> [ 维基百科 ]
使用简单的符号标识不同的标题,将某些文字标记为粗体或者斜体,创建一个链接等,详细语法参考帮助?。
本编辑器支持 Markdown Extra , 扩展了很多好用的功能。具体请参考Github.
表格
Markdown Extra 表格语法:
项目 | 价格 |
---|---|
Computer | $1600 |
Phone | $12 |
Pipe | $1 |
可以使用冒号来定义对齐方式:
项目 | 价格 | 数量 |
---|---|---|
Computer | 1600 元 | 5 |
Phone | 12 元 | 12 |
Pipe | 1 元 | 234 |
定义列表
- 这里是1
- 这里是2
- 这里是3
- 这里是1
- 这里是2
- 这里是3
Markdown Extra 定义列表语法:
项目1
项目2
: 定义 A
: 定义 B
项目3
: 定义 C
: 定义 D
> 定义D内容
代码块
代码块语法遵循标准markdown代码,例如:
@requires_authorization
def somefunc(param1='', param2=0):
'''A docstring'''
if param1 > param2: # interesting
print 'Greater'
return (param2 - param1 + 1) or None
class SomeClass:
pass
>>> message = '''interpreter
... prompt'''
脚注
生成一个脚注[1].
目录
用 [TOC]
来生成目录:
[TOC]
数学公式
使用MathJax渲染LaTex 数学公式,详见math.stackexchange.com.
- 行内公式,数学公式为:$\Gamma(n) = (n-1)!\quad\forall n\in\mathbb N$。
- 块级公式:
$$ x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a} $$
更多LaTex语法请参考 这儿.
UML 图:
可以渲染序列图:
张三->李四: 嘿,小四儿, 写博客了没?
Note right of 李四: 李四愣了一下,说:
李四-->张三: 忙得吐血,哪有时间写。
或者流程图:
st=>start: 开始
e=>end: 结束
op=>operation: 我的操作
cond=>condition: 确认?
st->op->cond
cond(yes)->e
cond(no)->op
离线写博客
即使用户在没有网络的情况下,也可以通过本编辑器离线写博客(直接在曾经使用过的浏览器中输入write.blog.csdn.net/mdeditor即可。Markdown编辑器使用浏览器离线存储将内容保存在本地。
用户写博客的过程中,内容实时保存在浏览器缓存中,在用户关闭浏览器或者其它异常情况下,内容不会丢失。用户再次打开浏览器时,会显示上次用户正在编辑的没有发表的内容。
博客发表后,本地缓存将被删除。
用户可以选择 <i class="icon-disk"></i> 把正在写的博客保存到服务器草稿箱,即使换浏览器或者清除缓存,内容也不会丢失。
注意:虽然浏览器存储大部分时候都比较可靠,但为了您的数据安全,在联网后,请务必及时发表或者保存到服务器草稿箱。
浏览器兼容
- 目前,本编辑器对Chrome浏览器支持最为完整。建议大家使用较新版本的Chrome。
- IE9以下不支持
- IE9,10,11存在以下问题
