javascript - 将数组从 View 传递到 Controller

Question

我正在尝试将数组从 View 传递到 Controller 。到目前为止我有这个:

<form method="post">
    <% for(let i = 0; i < websites.length; i++){ let website = websites[i]; %>
    <fieldset>
        <label for="website<%= i %>" class="col-sm-2">Website <%= i + 1 %></label>
        <input name="website<%= i %>" id="website<%= i %>" value="<%= website %>" type="text"/>
    </fieldset>
    <% } %>
    <button class="btn btn-primary col-sm-offset-2">Generate report</button>
</form>

这是 Controller

const websites = Object.keys(req.body).filter(key => key.startsWith('website'));
console.log(websites);

问题是控制台记录了以下内容:

[ 'website0', 'website1' ]

所以我猜它正在获取名字。我该如何获取值？

Answer 1

另一种方法是使用函数map

const websites = Object.keys(req.body)
                       .filter(key => key.startsWith('website'))
                       .map(k => req.body[k]);
