Question

我正在尝试从node / express迭代EJS中的JSON数据，当它在第6个引脚上时，将另一个引脚扔进flexbox。

当我尝试以这种方式添加代码时会弹出致命错误（打击）。如何在没有致命错误的情况下实现我的目标？

谢谢！

<% for(i=0; i < articles.length; i++) { %>

                <div class="pin" style="margin:1.25rem;">
                    <a href="/blog/<%- articles[i].slug %>">
                            <img class="blog-img" src="<%- articles[i].image %>" alt="blog post" style="width:20%;"/>
                    </a>
                    <h2><%- articles[i].title %></h2>
                    <p>
                        <%- articles[i].summary %>
                    </p>
                    <a class="readmore" style="position:relative; margin-top:2rem;" href="/blog/<%- articles[i].slug %>">READ MORE</a>
                </div>



                <% if( i = 5 ) { %>
                    <div class="pin" style="margin:1.25rem;">
                        <img src="images/logo-dark@2x.png" alt="Dome Logo" />
                        <div class="form-group">
                            <input onSubmit="submitData()" id="prospect-form" type="email" placeholder="Email Address" class="form-control" style="vertical-align: baseline; display:inline-block; background-color: white; border: none;" />
                            <button onSubmit="submitData()" id="form-submit" onClick="submitData()" class="btn btn-active" type="submit" style="display: inline-block">Submit</button>
                        </div>
                    </div>

                <% } %>

    <% } %>

编辑：if语句绝对是杀了我的机器。如果我留下那个if节点中的语句使用98％的CPU和1GB的RAM。如果我拿出来它恢复正常。正常是大约60MB的RAM和0％的CPU。

Answer 1

由于您尝试将值5附加到if条件中的 i ，而不是使用==比较参数来检查其值，因此您的循环会卡住。

您的if声明应为

<% if( i == 5 ) { %>
