Question

我只是想在用户点击添加按钮时添加此表单。每次用户点击添加按钮时，新的表单展开，添加按钮，当用户点击删除按钮时，它将逐个删除所有表单但除外父母一个。

    </html>

所以，我不知道如何使用javascript实现这一目标。

首先从原始delete中移除form，以便您可以保留对父form的删除。您可以在cloned forms上动态添加，如下所示：

var id=0;
$(document).ready(function() {
  //attach a click event to add button whose id begins with plus, since id's have
  //to be unique in DOM, we will be generating new id as in plus1, plus2 etc.,
  //when we clone the form and before we append it. So the below selector means
  //attach click events to those buttons whose id begins with plus. ^= means begins with
  $(document).on('click',"button[id^=plus]",function(e){
      e.preventDefault(); //prevent default action
      //create a delete button html
      var deleteBtn=$('<button id="minus">delete</button>');
      //clone the parent form which will be in first
      var clonedForm=$('form:first').clone();
      //you can also do var clonedForm=$("#internship").clone();
      id++; //increment the global id
      
      //loop through each element which contains id property and replace with a new one 
     //to maintain uniqueness
      clonedForm.find('[id]').each(function(){
        var $el=$(this); //get the reference to element 
        $el.attr('id',$el.attr('id')+id); //replace its id with new one 
      });
      deleteBtn.attr('id',deleteBtn.attr('id')+id);//replace delete button's id
      clonedForm.attr('id',clonedForm.attr('id')+id); //replace cloned form's id
      //append deleteBtn to td where add exists
      clonedForm.find("td[id^=training]").append(deleteBtn);
     
      //append cloned form to inner-aw-div
      clonedForm.appendTo(".inner-aw-div");
  });
  //delete event to delete the closest form
  $(document).on('click',"[id^=minus]",function(){
    $(this).closest('form').remove();  //just remove the parent form
  })
});
