如何通过fancybox向引导多选复选框下拉菜单添加选项

Question

我有多选复选框下拉菜单。我创建了花式框，并在花式框上输入文本字段值并单击提交按钮。

我需要动态添加下拉值或更新下拉值。请帮忙。

您可以添加如下选项：https://jsfiddle.net/kodedsoft/ufoeky49/1/

var values =0;  // or any value grabbed from inputs
$(".btn").on("click",function(){
   $('select').append($('<option>', {
     value: values,
     text: values
   }));

});

你的情况

var getTxtVal = $('#txt1').val();  // or any value grabbed from inputs
$(".btn").on("click",function(){
   $('select').append($('<option>', {
     value: getTxtVal,
     text: getTxtVal
   }));

});

应该是这样的：

$(function () {
var $callback = $("#callback");
var optionsAsString = "";
$('#btn1').click(function (e) {
    e.preventDefault();
    var $val = $('#txt1').val() ;
    $('select').append($('<option>', {
      value: $val,
      text: $val
      }));
});

$("select").multiselect({

    click: function (event, ui) {
        $("#callback").text(ui.value + ' ' + (ui.checked ? 'checked' : 'unchecked'));
    },
    beforeopen: function () {
        $("#callback").text("Select about to be opened...");
    },
    open: function () {
        $("#callback").text("Select opened!");
    },
    beforeclose: function () {
        $("#callback").text("Select about to be closed...");
    },
    close: function () {
        $("#callback").text("Select closed!");
    },
    checkAll: function () {
        $("#callback").text("Check all clicked!");
    },
    uncheckAll: function () {
        $("#callback").text("Uncheck all clicked!");
    },
    optgrouptoggle: function (event, ui) {
        var values = $.map(ui.inputs, function (checkbox) {
            return checkbox.value;
        }).join(", ");

        $("#callback").html("<strong>Checkboxes " + (ui.checked ? "checked" : "unchecked") + ":</strong> " + values);
    }
});
$('#a1').fancybox({
    transitionIn: "elastic",
    transitionOut: "elastic",
    overlayShow: false,
    target: this,
    orig: $("img", this),
    titlePosition: "inside",
    titleFormat: titleFormat,
    type: 'iframe',
    padding: 0,
    closeClick: false,

});
var titleFormat = function (titleStr, currentArray, currentIndex, currentOpts) {
    titleStr = '<span id="fancybox-title-' + currentOpts.titlePosition + '">' + titleStr + '<\/span>';
    return titleStr;
};

});
