javascript - 清除jquery多选中选定选项的复选框

Question

在下面的小提琴中，我有一个引导模式，并且有一个 Select Users MultipleSelect。

我需要清除模式关闭时的选择，例如将下拉菜单设置为默认值而不进行任何选择。

例如，如果我选择用户 1 和用户 2，那么在模态关闭时，不应选择任何一个。之前的选择必须消失。

我正在尝试的代码并没有帮助我，这里也没有关于堆栈溢出的任何帖子。

我尝试过的一点是：

$("#usersDropDown option:selected").attr("checked",false);

和这个：

$("#usersDropDown option:selected").attr("selected",false);

还有这个：

$("#usersDropDown option:selected").removeAttr("checked");

请指导我该怎么办？

嗨，你现在可以检查小提琴吗？我猜它的工作原理。我将此代码添加到显示的模式中。如果需要，可以将其添加到隐藏功能

$("#usersDropDown").siblings(".ms-parent")
 .find("li.selected input[type='checkbox']").click();

您可以使用$('#usersDropDown').multipleSelect("uncheckAll");inorder 取消全选。

JSFiddle

var currentDate = new Date();
var day = currentDate.getDate();

if (day < 10)
  day = "0" + day;

var month = currentDate.getMonth() + 1;
if (month < 10) {
  month = "0" + month;
}
var hours;
var year = currentDate.getFullYear();
todayDateReport = year + "-" + month + "-" + day;
$("#currentDate").html(todayDateReport);
startDate = todayDateReport + " 00:00:00";
endDate = todayDateReport + " 23:59:59";
hours = " 00:00";

$('.input-group').datetimepicker({
  format: 'YYYY-MM-DD HH:mm',
  collapse: true,
  sideBySide: false,
  useCurrent: false,
  showClose: true,
});
 $('#hoursInput').datetimepicker({
             format: 'HH:mm',

             collapse:true,
			 sideBySide:false,
			 useCurrent:false,
			 showClose:true,
			 focusOnShow: false,
		 });
$("#startDateInputExpiry").val(startDate);
$("#endDateInputExpiry").val(endDate);
$("#hoursInput").val(hours);
$("#hoursInputExpiry").val(hours);

$("#sendDropDownOptions").on('change', function() {
  if ($("#sendDropDownOptions option:selected").text() == "Datetime") {
    $("#durationHoursSend").addClass('hide');
    $("#sendTD").append($("#startdatetimeSend"))
    $("#startdatetimeSend").removeClass('hide');
  } else if ($("#sendDropDownOptions option:selected").text() == "Hours") {
    $("#startdatetimeSend").addClass('hide');
    $("#sendTD").append($("#durationHoursSend"))
    $("#durationHoursSend").removeClass('hide');
  } else {
    $("#startdatetimeSend").addClass('hide');
    $("#durationHoursSend").addClass('hide');
  }
});

$('#shareLocationModal').on('shown.bs.modal', function() {

$('#usersDropDown').multipleSelect("uncheckAll");

  if ($("#expiryDropDownOptions option:selected").text() == "DatetimeExp") {
    $("#startdatetimeExpiry").removeClass('hide');
    $("#expiryTD").append($("#startdatetimeExpiry"))
  }
});
$("#expiryDropDownOptions").on('change', function() {

    $("#expiryTD").append($("#startdatetimeExpiry"))
  }
  else {
    $("#durationHoursExpiry").addClass('hide');
    $("#startdatetimeExpiry").addClass('hide');
  }
});

$("#usersDropDown").multipleSelect({
  placeholder: "Select Users",
  selectAll: true,
  width: "100%",
  filter: true,
});

$("#send").on("click", function()
        {
                $("#sendDropDownOptions").val('Now').trigger('change');
        });

.modal-body {
  max-height: calc(100vh - 210px);
  overflow-y: auto;
}

您可以使用以下代码重置表单数据和引导模式窗口下拉菜单中的多选框以清除内容。

$('#shareLocationModal').on('hidden.bs.modal', function(){
    $('#usersDropDown').multipleSelect('refresh'); // to reset the multi select users dropdown
    $(this).find('form')[0].reset(); // To reset form fields
})

你试过$("#usersDropDown").prop('selectedIndex',-1);吗？
