Question

我正在尝试在我的快递应用中加载ejs模板。我将'view engine'设置为ejs，并将ejs模板传递给response.render。但是，当我导航到localhost：8000时，我只看到文字形式的include语句。

模板文件： index.ejs

{% include('commonheader') %}
<div id='mainbody' class='container-fluid'>
  <nav>
    {%- include('mainheader', {
      navbar: navbar_options
    }) %}
  </nav>
</div>
{%- include('commonfooter', {
  footer: sitemap
}) %}

commonheader.ejs

<!DOCTYPE html>
<html lang='en'>
  <head>
    <meta charset='utf-8'>
    <title><%= title %></title>

    <!-- bootstrap -->
    <link rel="stylesheet"

              crossorigin="anonymous"></script>

    <!-- Custom stylesheets and js -->
    <%- if(stylesheets){
      if(typeof stylesheets == []){
        Array.prototype.forEach(function(sheet){
          %}<link rel='stylesheet' href= {%= sheet %}>{%
        }, stylesheets);
      }
      else{
        %}<link rel='stylesheet' href= {%= Array.prototype.shift.call(stylesheets) %}>{%;
      }
    }; %}
  </head>
  <body>

commonfooter.ejs

<footer>
  <% if(footer){
    for(let k in footer){
      if(typeof footer[k] []){
        Array.prototype.forEach.call(function(link){
          %}<a href= {%= link['href'] %}>
            <li>{%= link['name'] %}</li>
          </a>{%
        });
      }
      else{
        %}<a href= {%= link['href'] %}>
          <ul>{%= link['name'] %}</ul>{%
      }
    }
  %}
</footer>
</body>
</html>

routes.js

const express = require('express');
const path = require('path');
const appinst = express();
const _template_dir = '/static';
const _root_addr = '127.0.0.1:8000';

// bind render engine to ejs
appinst.set('views', path.join(__dirname,'views'));
appinst.set('view engine', 'ejs');


appinst.get('/', function(request, response){
  response.render('index', {
    css_stylesheets: [
      'css/index.css',
    ],
    navbar_options: [
      {
        'href': _root_addr + '/',
        'name': 'Home'
      },
      {
        'href': _root_addr + '/create',
        'name': 'Create'
      },
      {
        'href': _root_addr + '/howto',
        'name': 'How To'
      }
    ],
    sitemap: [
      {
        'href': _root_addr + '/',
        'name': 'Home'
      },
      {
        'href': _root_addr + '/aboutus',
        'name': 'About Us'
      },
      {
        'href': _root_addr + '/create',
        'name': 'Create'
      },
      {
        'href': _root_addr + '/howto',
        'name': 'How To'
      },
      {
        'href': _root_addr + '/contactus',
        'name': 'Contact Us'
      }
    ]
  });

});

浏览器输出：

{% include('commonheader') %}
{%- include('mainheader', { navbar: navbar_options }) %}
{%- include('commonfooter', { footer: sitemap }) %}

Answer 1

我认为您错误输入了包含内容，应该如下所示：

<%- include('mainheader', { navbar: navbar_options }); %>

但是您的代码中缺少开始和结束标记<%- %>

您仅使用%-和%

{%- include('mainheader', { navbar: navbar_options }) %}

EJS视图不渲染
