我有一个用户记录表，点击“编辑”按钮会弹出一个jquery对话框。对于每个记录编辑，应该使用该记录值填充对话框表单。 我已设法将这些记录值存储在jquery变量中，并使用它来填充表单。
输入[= text]元素工作正常，即输入值使用相应的记录值正确填充。但是当涉及下拉元素[使用select2]时，先前记录中的值将保留在下一个对话框中。
我尝试清除下拉元素，但结果与预期不符。
这是我试过的：
$('a.leave_request_edit').click(function(e)
{
e.preventDefault();
var empName = $(this).closest('tr').attr('data-empName');
var reason = $(this).closest('tr').attr('data-reason').trim();
var leaveFromFormatted = $(this).closest('tr').attr('data-leaveFromFormatted').trim();
var leaveToFormatted = $(this).closest('tr').attr('data-leaveToFormatted').trim();
var leaveTypeId = $(this).closest('tr').attr('data-leaveTypeId').trim();
var userLeaveStatus = $(this).closest('tr').attr('data-leaveStatus').trim();
var empID = $(this).closest('tr').attr('data-empID').trim();
var issuedDateOld = $(this).closest('tr').attr('data-issuedDate').trim();
$('#updateMainDialog').dialog
({
resizable: false,
draggable: false,
height: 220,
width: 400,
modal: true,
buttons: {
"Edit Request" : function()
{
$(this).dialog('close');
$('#leave_modal_edit').show();
$('#leave_description_edit').val(reason);
$('#leave_date_from_edit').val(leaveFromFormatted);
$('#leave_date_to_edit').val(leaveToFormatted);
$('#leave_type_edit option[value = '+leaveTypeId+']').attr('selected', 'selected').trigger('change');
$('#request-holder').hide();
$('#dialog').dialog(
{
resizable: false,
draggable: false,
height: 430,
width: 451,
modal: true,
title: 'Leave Request By' + empName,
buttons:{
"Update Request": function(){
var id = leave_id;
var teamSelectionEdit = $('#team_selection_edit').val();
var previousLeaveStatus = userLeaveStatus;
var leaveDescriptionEdit = $('#leave_description_edit').val();
var leaveTypeEdit = $('#leave_type_edit').val();
var leaveFromEdit = $('#leave_date_from_edit').val();
var leaveToEdit = $('#leave_date_to_edit').val();
var userID = empID;
var issued_date = $('#issued_date').val();
if($('#leave_modal_edit').valid())
{
$('#request-holder').show();
$.ajax({
url: "leave/request/edit",
data:
{
id: id,
user_id: empID,
leave_type: leaveTypeEdit,
leave_type_old: leaveTypeId,
issued_date: issued_date,
issued_date_old: issuedDateOld,
leave_from: leaveFromEdit,
leave_from_old: leaveFromFormatted,
leave_to: leaveToEdit,
leave_to_old: leaveToFormatted,
team_selection: teamSelectionEdit,
leave_description: leaveDescriptionEdit,
leave_description_old: reason,
leave_status: previousLeaveStatus,
employeeName: empName,
edit: true
},
type: 'POST',
cache: false,
success: function(data, resp)
{
$('#request-holder').hide();
console.log(data);
// return;
var json = data, obj = JSON && JSON.parse(json) || $.parseJSON(json);
if(obj.status == 'error')
{
alert('error');
return false;
}
$('#updateMainDialog').dialog('close');
location.reload(true);
},
error: function(data, resp)
{
console.log(data);
}
}); // ajax
}
},
"Cancel": function()
{
// $('#team_selection_edit').select2('val','');
// $('#leave_type_edit').select2('val','');
$(this).dialog('close');
}
}
});
},
// and rest of it...
以下是记录的显示方式，如果有帮助
<tr
id="<?php echo $leaveRecord['id']; ?>"
data-reason = "<?php echo $leaveRecord['leave_description'];?>"
data-leaveFromFormatted = "<?php echo Utility::dateFormatter($leaveRecord['leave_from']); ?>"
data-leaveToFormatted = "<?php echo Utility::dateFormatter($leaveRecord['leave_to']); ?>">
<td><?php echo $leaveRecord['leave_from']; ?></td>
<td><?php echo $leaveRecord['leave_to']; ?></td>
<td><?php echo $leaveRecord['leave_description']; ?></td>
<td><?php echo $username->status; ?></td>
<td>
<a href="#" class="btn btn-danger square-btn-adjust leave_request_delete" "><i class="fa fa-trash-o"></i></a>
<a href="#" class='btn btn-primary square-btn-adjust leave_request_edit'><i class="fa fa-pencil-square-o"></i></a>
</td>
</tr>
这是我的对话框：

我只需保留属于jquery中记录的那些值。 这一切都很漫长而无聊......但是请任何帮助表示赞赏..谢谢:)。
