Nodejs + express + ejs

特性

• <% %> 用于控制流
• <%= %> 用于转义的输出 （会对数据字符进行转义）

  // 数据源
  // app.js
  
  var tem={
      title:"我是中间部分",
      info:[{Name:"davi", Time:1497591600000},{name:"bill", Time:1497591600000},{name:"can", Time:1497591600000}]
  };
  
  // index.ejs
  //  ‘<%=JSON.stringify(info)%>‘
  [{"Name":"davi","Time":1497591600000},{"name":"bill","Time":1497591600000},{"name":"can","Time":1497591600000},{"name":"can","Time":1497592600000}]

• <%- %> 用于非转义的输出  （数据原本是什么就输出什么）
• -%> 结束标签用于换行移除模式
• 带有 <%_ _%> 的控制流使用空白字符移除模式

添加外部js

　　ejs模板中未能直接使用外挂js 方法， 但能够通过nodejs中 app.js 引入，挂载到 全局变量locals中，ejs中直接调用，直接上代码：

// common.js

var Common = {
           timeToDate: function(ts) {
        var Y, M, D, h, m, s;
        var date = new Date(ts);
        Y = date.getFullYear() + ‘-‘;
        M = (date.getMonth() + 1 < 10 ? ‘0‘ + (date.getMonth() + 1) : date.getMonth() + 1) + ‘-‘;
        D = (date.getDate() < 10 ? ‘0‘ + (date.getDate()) : date.getDate()) + ‘ ‘;
        h = (date.getHours() < 10 ? ‘0‘ + (date.getHours()) : date.getHours()) + ‘:‘;
        m = (date.getMinutes() < 10 ? ‘0‘ + (date.getMinutes()) : date.getMinutes()) + ‘:‘;
        s = (date.getSeconds() < 10 ? ‘0‘ + (date.getSeconds()) : date.getSeconds());
        return (Y + M + D + h + m + s);
    }
};
module.exports = Common;

// nodejs  app.js

var http=require("http");
var express=require("express");
var fs = require("fs");
var bodyParser = require(‘body-parser‘);
var Common = require("./publice/common");
var app=express();

var tem={
    title:"我是中间部分",
    info:[{Name:"davi", Time:1497591600000},{name:"bill", Time:1497591600000},{name:"can", Time:1497591600000}]
};

//挂载静态资源处理中间件
//app.locals.Common = Common;
app.use(function(req, res, next){
    res.locals.Common = Common;
    next();
});

............................

// index.ejs

<div>
 <%info.forEach(function (name) { %>
                    <dl class="clear-fix">
                        <dd class="wd150"><%= Common.timeToDate(name.Time)%></dd>
                        <dd class="wd120 alc">50天</dd>
                        <dd class="wd120 alc">￥100</dd>
                    </dl>
                    <%})%>
