bootstrap 4 中的输入标签未内联

Question

我正在使用 Bootstrap 4 和 Vue.js 来填充输入表单，但我不知道如何使 标签对齐，之前，使用输入类型文件。

<div v-for="problem in problems">
    <div class="row">
        <div class="col">
            <form method="POST" action="/submission" enctype="multipart/form-data" class="form-group">
                <!-- sending the student information -->
                <input type="text" name="courseNumber" :value="courseIdSelected" style="display: none;">
                <input type="text" name="assignmentNumber" :value="assignmentSelected.id" style="display: none;">
                
                <div class="form-group form-inline">
                    <label :for="problem.name">Code submissions {{ problem.name }}</label>
                    <input type="file" name="document" :id="problem.name" class="form-control-file"/>
                </div>
                <div class="form-group">
                    <input type="submit" class="btn btn-primary"/>
                </div>
            
            </form>
        </div>
    </div>
</div>

是否有一些 解决方案仅使用一些 Bootstrap class，或者我需要将样式 (CSS) 更改为使其在与输入相同的行中显示标签。

来自 bs4 的内联示例：

  <div class="form-group row"> 
    <label :for="problem.name" class="col-sm-2 col-form-label">Code submissions {{ problem.name }}</label>
    <div class="col-sm-10"> 
<input type="file" name="document" :id="problem.name" class="form-control"/>
    </div>
  </div>

如果您在标签内进行输入，它将帮助您解决问题

将您的 input 标签包裹在 div 内将解决您的问题

<!-- Bootstrap CSS -->
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css" integrity="sha384-Vkoo8x4CGsO3+Hhxv8T/Q5PaXtkKtu6ug5TOeNV6gBiFeWPGFN9MuhOf23Q9Ifjh" crossorigin="anonymous">

<div v-for="problem in problems">
  <div class="row">
    <div class="col">
      <form method="POST" action="/submission" enctype="multipart/form-data" class="form-group">
        <!-- sending the student information -->
        <input type="text" name="courseNumber" :value="courseIdSelected" style="display: none;">
        <input type="text" name="assignmentNumber" :value="assignmentSelected.id" style="display: none;">
        <div class="form-group form-inline">

          <label :for="problem.name">Code submissions {{ problem.name }}</label>

          <!-- wrapping your input tag inside a div -->
          <div>
            <input type="file" name="document" :id="problem.name" class="form-control-file" />
          </div>

        </div>
        <div class="form-group">
          <input type="submit" class="btn btn-primary" />
        </div>
      </form>
    </div>
  </div>
</div>
