editormd实现Markdown编辑器写文章功能

想在项目里引入Markdown编辑器实现写文章功能，网上找到一款开源的插件editormd.js

介绍网站：https://pandao.github.io/editor.md/examples/index.html

源码：https://github.com/pandao/editor.md，插件代码已经开源到github上了。

可以先git clone下载下来

git clone https://github.com/pandao/editor.md.git

现在介绍一下怎么引入JavaWeb项目里，可以在Webapp(WebContent)文件夹下面，新建一个plugins的文件夹，然后再新建editormd文件夹，文件夹命名的随意。

在官方网站也给出了比较详细的使用说明，因为我需要的个性化功能不多，所以下载下来的examples文件夹下面找到simple.html文件夹

加上样式css文件

<link href="<%=basePath %>plugins/editormd/css/editormd.min.css"
	rel="stylesheet" type="text/css" />

关键的JavaScript脚本

<script type="text/javascript"
	src="<%=basePath %>static/js/jquery-1.8.3.js"></script>
<script type="text/javascript"
	src="<%=basePath %>plugins/editormd/editormd.min.js"></script>
<script type="text/javascript">
	var testEditor;
	
	$(function() {
	    testEditor = editormd("test-editormd", {
	        width   : "90%",
	        height  : 640,
	        syncScrolling : "single",
	        path    : "<%=basePath %>plugins/editormd/lib/"
	    });
	});
</script>

写个jsp页面

<%@ page language="java" contentType="text/html; charset=UTF-8"
		 pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt"%>
<%
	String path = request.getContextPath();
	String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE html>
<html>
<head>
<base href="<%=basePath %>">
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Nicky's blog 写文章</title>
<link rel="icon" type="image/png" href="static/images/logo/logo.png">

<style type="text/css">
	#articleTitle{

</style>
</head>
<body>
	<div id="layout">

	var testEditor;
	
	$(function() {
	    testEditor = editormd("test-editormd", {

	    });
	    categorySelect.init();
	});

	/* 文章类别下拉框数据绑定 */
	var categorySelect = {
		init: function () {//初始化数据
			$.ajax({
                type: "GET",
                url: 'articleSort/listArticleCategory.do',
                dataType:'json',

                success: function(data){
                	//debugger;
                	data = eval(data) ;
                    categorySelect.buildOption(data);
                }
            });

            var optionStr ="";
            for(var i=0 ; i < data.length; i ++) {
                optionStr += "<option value="+data[i].typeId+">";

	/* 发送文章*/
	var writeArticle = {

                var title = $("#articleTitle").val();

                    }

			}

                return false;
			}

			return true;
        }
	}
	
</script>
</body>
</html>

然后后台只要获取一下参数就可以，注意的是path参数要改一下

testEditor = editormd("test-editormd", {
	        width   : "90%",
	        height  : 640,
	        syncScrolling : "single",
	        path    : "<%=basePath %>plugins/editormd/lib/"
	    });

SpringMVC写个接口获取参数进行保存，项目用了Spring data Jpa来实现

package net.myblog.entity;

import javax.persistence.*;
import java.util.Date;

/**

	}

	@Column(length=100)
	public String getImgPath() {

	}

	public void setImgPath(String imgPath) {
		this.imgPath = imgPath;
	}

	@Column(nullable=false)
	public String getArticleContent() {

	}

	public void setArticleContent(String articleContent) {

	public int getArticleClick() {

	public void setArticleClick(int articleClick) {

	public void setArticleSupport(int articleSupport) {

	public int getArticleUp() {

	public void setArticleUp(int articleUp) {

	@Column(nullable=false)
	public int getArticleType() {

	}

	public void setArticleType(int articleType) {

	}

	public int getTypeId() {
		return typeId;
	}

	public void setTypeId(int typeId) {
		this.typeId = typeId;
	}

	@JoinColumn(name="articleId",insertable = false, updatable = false)
	@ManyToOne(fetch=FetchType.LAZY)
	public ArticleSort getArticleSort() {
		return articleSort;
	}

	public void setArticleSort(ArticleSort articleSort) {
		this.articleSort = articleSort;
	}
	
}
