关闭jquery ui对话框后如何删除内容

Question

在我的项目中，我使用jquery ui对话框。

在send_div关闭之前，staff_div具有John-Stack，而sltStfId具有Robert-Sansa。 在send_div关闭之后，我想删除“ John-Stack”和“ Robert-Sansa”的内容。 因此，在初始化send_div对话框时，我选择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>

但是不幸的是，它失败了。我选中了send_div对话框，然后再次打开它。 “ John-Stack”和“ Robert-Sansa”仍然存在。

谁能帮我？

您可能想要您的这段代码。 希望能帮助到你。

    <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

您要使用close事件功能，而不要使用beforeclose事件。

另外，您还希望将容器div定位为empty()包含在其中的所有元素。

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

 $(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(); }
