javascript - 如何根据表单的文本输入准备值列表？

Question

给定以下形式:

<form class="email-form" action="" method="PUT" data-remote="true" data-method="put">
  <ul>
    <li>
      <label for="sEmail1">
        <input type="text" id="sEmail1" name="emails[]" value="d@google.com"
               placeholder="">
      </label>
    </li>
    <li>
      <label for="sEmail2">
        <input type="text" id="sEmail2" name="emails[]" value="d2@google.com"
               placeholder="">
      </label>
    </li>
    <li>
      <label for="sEmail3">
        <input type="text" id="sEmail3" name="emails[]" value="d3@google.com"
               placeholder="">
      </label>
    </li>
  </ul>
  <button type="submit">Continue</button>
</form>

如何使用查询来获取完整的电子邮件列表并将其发布到 Rails，如下所示:

Parameters: {"emails"=>{"list"=>["d@google.com", "d2@google.com","d2@google.com"]}}

我有以下内容:

    $.ajax({
        type: 'POST',
        url: '/send_invites',
        data: {
            emails : {
                list : $('.email-form').serialize()
            },
            _method : 'PUT'
        },
        success : function() {
        }
    });

试试这个:

emails = new Object();
emails.list = [];
i = 0;

$("input[name^='email']").each(function(){
   if(i < 3) {
    emails.list[i] = $(this).val();
    i++
  }

})

alert(JSON.stringify(emails));  

或者:

parameters = new Object();
parameters.emails = new Object()
parameters.emails.list= [];
i = 0;

$("input[name^='email']").each(function(){
   if(i < 3) {
    parameters.emails.list[i] = $(this).val();
    i++
  }

})

alert(JSON.stringify(parameters));
