Question

在我的项目中，我使用jquery ui对话框。

在transmit_div关闭之前，staff_div有John-Stack，sltStfId有Robert-Sansa。在transmit_div关闭后，我想删除内容 “John-Stack”和“Robert-Sansa”。所以我在初始化transmit_div对话框时选择了beforeclose参数。

这是js代码：

<script>
$(document).ready(function()
{ 
 $('#transmit_app').click(function(){
    $('#transmit_div').dialog("open");
    $('#transmit_div').dialog("option","title");
   });
});
$('#transmit_div').dialog({
  autoOpen:false,
  title:"selectUser",
  modal:true,
  height:500,
  width:600,
  show:{effect:"blind",duration: 1000},
  hide:{effect:"explode",duration: 1000},
  beforeclose: function() {
   staff_div.innerHTML="<input type='button' id='selAllButton'  value='selectAll'><br />";
   sltStfId.innerHTML=""; 
   }
  });
  </script>

这是html代码：

<input type="button" id="transmit_app" value="trsmit" />
<div id="transmit_div" >
<div id="staff_div" class="staff" >
 <input type="button" id="selAllButton"  value="selectAll"><br />
 John-Stack
</div>
 <div class="selected_staff" >
 <input type="button" onclick="delete_allStaff()" value="deleteAll">
 <div id="sltStfId">
   Robert-Sansa
 </div>
</div>
</div>

但不幸的是，它失败了。我收集transmit_div对话框，然后再次打开它。 “John-Stack”和“Robert-Sansa”仍然存在。

谁能帮帮我？

Answer 1

你可能想要这个代码。希望它有所帮助。

    <script>
    $(document).ready(function(){ 
        $('#transmit_app').click(function(){
            $('#transmit_div').dialog("open");
            $('#transmit_div').dialog("option","title");
        });

        $('#transmit_div').dialog({
            autoOpen:false,
            title:"selectUser",
            modal:true,
            height:500,
            width:600,
            show:{effect:"blind",duration: 1000},
            hide:{effect:"explode",duration: 1000},
            beforeClose: function myCloseDialog() {
                $('#staff_div').html("<input type='button' id='selAllButton'  value='selectAll'><br />");
                $('#sltStfId').html("");
            }
        });
    });
</script>

$(document).ready(function()
{ 
 $('#transmit_app').click(function(){
    $('#transmit_div').dialog("open");
    $('#transmit_div').dialog("option","title");
   });
     $("#delete").click(function(){
   $("#sltStfId,#staff_div").remove();
   })
});
$('#transmit_div').dialog({
  autoOpen:false,
  title:"selectUser",
  modal:true,
  height:500,
  width:600,
  show:{effect:"blind",duration: 1000},
  hide:{effect:"explode",duration: 1000},
  beforeclose: function() {
   staff_div.innerHTML="<input type='button' id='selAllButton'  value='selectAll'><br />";
   sltStfId.innerHTML=""; 
   
   }
 
  });

Answer 3

You want to use the close event function, not the beforeclose event.

Also you want to target the container div to empty() all elements contained in it.

$("#transmit_div").empty();

Example

$(document).ready(function() {
  $('#transmit_app').click(function() {
    $('#transmit_div').dialog("open");
    $('#transmit_div').dialog("option", "title");
  });
});
$('#transmit_div').dialog({
  autoOpen: false,
  title: "selectUser",
  modal: true,
  height: 500,
  width: 600,
  show: {
    effect: "blind",
    duration: 1000
  },
  hide: {
    effect: "explode",
    duration: 1000
  },
  close: function() 
  {
     deleteAll();
  }
});

$("#delete-all").on("click", function()
{
   deleteAll();
});

function deleteAll()
{
  $("#transmit_div").empty();
}
