Question

forEach不是函数当我在ejs中使用nodejs迭代json文件时在迭代时给出一些错误..下面是我在.ejs文件，json和nodeJS中完成的三个部分

这是我的JSON数据

       <pre> 
        {
            "MenuName": "Main Menu Here",
            "widget": {
                "window": {
                    "data": "Click Here",
                    "title": "Sample Konfabulator Widget",
                    "name": "main_window",
                    "width": 500,
                    "height": 500
                },
                "window": {
                    "data": "Click Here",
                    "src": "Images/Sun.png",
                    "name": "sun1",
                    "hOffset": 250,
                    "vOffset": 250,
                    "alignment": "center"
                },
                "window": {
                    "data": "Click Here",
                    "size": 36,
                    "style": "bold",
                    "name": "text1",
                    "hOffset": 250,
                    "vOffset": 100,
                    "alignment": "center",
                    "onMouseUp": "sun1.opacity = (sun1.opacity / 100) * 90;"
                }
            }
        }
        </pre>

这是我的ejs

        <html>
        <head>
        <title><%= title %></title>
        </head>
        <body>
            <h1> My Name Is <%= title %></h1>
            <h1> My Name Is <%= printIt.MenuName %></h1>
            <ul>
                <% printIt.widget.forEach(function(item){%> 
                    <li><%= item.window.data%></li>
                <% }); %>
            </ul>
        </body> 

        </html>
        </pre>

<pre>
    app.locals.printIt = require("./sample.json");
</pre>

    I can able to print 
    My Name Is <%= title %> and My Name Is <%= printIt.MenuName %>

    What i missed here..?

Answer 1

首先，您的JSON数据将仅保留窗口小部件窗口的单个记录，哪个是最后一个。因为窗口键将覆盖先前的保持值。

使用此脚本更新您的脚本

commons-httpclient-3.1.jar
commons-codec-1.10.jar
commons-logging-1.2.jar

希望这有助于解决您的疑问!!

ejs forEach函数不适用于节点中的json数据
