个人博客项目之editormd实现写文章功能

心已赠人 2021-09-17 16:50 323阅读 0赞

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

关键的JavaScript脚本

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>

                        categorySelect.buildOption(data);

                    optionStr += data[i].name;
                    optionStr +="</option>";
                }
                $("#articleCategory").append(optionStr);
            }
    	}
    
    	/* 发送文章*/
    	var writeArticle = {
    	    doSubmit: function () {//提交
    	        if (writeArticle.doCheck()) {
    	            //debugger;
                    var title = $("#articleTitle").val();

                    var typeId = $("#articleCategory").val();
                    $.ajax({

    							setTimeout(function(){

    							},3000);
    						}
                        }
                    });
    			}
            },
    		doCheck: function() {//校验
                //debugger;
    			var title = $("#articleTitle").val();
    			var content = $("#articleContent").val();
    			if (typeof(title) == undefined || title == null || title == "" ) {
                    alert("请填写文章标题!");
    			    return false;
    			}
    
    			if(typeof (content) == undefined || content == null || content == "") {
                    alert("请填写文章内容!");
                    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
