将数组从视图传递到控制器

Question

I'm trying to pass an array from a view to a controller. So far I have this:

<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>

And this is the controller

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

The problem is the console logs this:

[ 'website0', 'website1' ]

So I'm guessing it's grabbing the names. How do I make grab the values instead?

Answer 1

An alternative is using the function map

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