Bootstrap 表单中的提交按钮对回车键没有反应

Question

我有以下 Bootstrap 表单：

<div class="modal-content">
  <div class="modal-header">
    <button type="button" class="close" data-dismiss="modal" aria-label="Close">
      <span aria-hidden="true">×,
      </span>
    </button>
    <h4 class="modal-title">Datei speichern
    </h4>
  </div>
  <div class="modal-body">
    <p>Gib einen Dateinamen ein
    </p>
    <div class="form-group">
      <label class="input-label" for="project-bar-input">
      </label>
      <input type="text" class="form-control" id="project-bar-input">
    </div>
  </div>
  <div class="modal-footer">
    <button type="button" class="modal-cancel btn btn-default" data-dismiss="modal">Abbrechen
    </button>
    <button type="submit" class="modal-action btn btn-primary" data-dismiss="modal">Speichern
    </button>
  </div>
</div>

我尝试使用

捕捉 ENTER 键事件

$( ".modal-content" ).find( "input#submit" ).click( function() {
    // submit
});

阅读后：

Submit button not working in Bootstrap form

但是没用。为什么？

Answer 1

$(function(){
  $('.modal-content').keypress(function(e){
    if(e.which == 13) {
      //dosomething
      alert('Enter pressed');
    }
  })
})
