javascript - 搜索在动态 Bootstrap 多选中不起作用

Question

我正在使用 http://davidstutz.github.io/bootstrap-multiselect/用于在我的网页中创建 Bootstrap 多选控件。

下面的静态数据 fiddle 链接是我想使用动态数据实现的:

https://jsfiddle.net/DROCKS/mrmLrsad/4/

//please refer the fiddle

如果选择框的值是静态的，搜索选项可以正常工作，但如果它们是动态创建的，则会创建多选。但是，搜索过滤器在这种情况下不起作用。然而，我的代码类似于下面的 fiddle ，唯一的区别是搜索过滤器部分在我的实际代码中不起作用，但在这个 fiddle 中起作用。

//please refer the fiddle

这是我的代码。HTML代码

<select id="lstFieldList" ></select>

jQuery 代码 [更新]:

function uncheckFields(field_id)
{
    $('#' + field_id).multiselect('deselectAll', true);
}

//json_obj is the value from the fiddle.

createMultiSelectBox(json_obj);

//this function creates the multiselect
function createMultiSelectBox(json_obj)
{
    var element_String = "";
    var default_ele_set = 0;
    var def_element_first = "1";                            //if the first Y flag should be considered
    var def_element_last = "n";                             //if the last Y flag should be considered
    var def_element = def_element_first;            //change the value here to toggle between default selection
    var tmp = [];

    for (var key in json_obj)
    {
        var val = json_obj[key];
        //alert("Key: " + key);

        var chk_box_ctr = 0;
        var element;

        for(var child_key in val)
        {
            //alert("key: " + child_key + "\nvalue: " + val[child_key]);

            var default_value = child_key.split(",")[7];

            //alert("default_value: " + default_value);

            if(!chk_box_ctr)
            {
                g_max_PageSize = child_key.split(",")[8];
                //alert("g_max_PageSize: " + g_max_PageSize);
            }

            if(def_element == def_element_first)
            {
                if(default_value == "Y" && !default_ele_set)
                {
                    //element_String += '<option value="' + child_key + '" selected="selected">' + val[child_key] + '</option>';
                    element = {"label": val[child_key],"value":child_key};
                }
                else
                {
                    //element_String += '<option value="' + child_key + '">' + val[child_key] + '</option>';
                    element = {"label": val[child_key],"value":child_key};
                }
            }
            else
            {
                if(default_value == "Y")
                {
                    //element_String += '<option value="' + child_key + '" selected="selected">' + val[child_key] + '</option>';
                    element = {"label": val[child_key],"value":child_key};
                }
                else
                {
                    //element_String += '<option value="' + child_key + '">' + val[child_key] + '</option>';

                    element = {"label": val[child_key],"value":child_key};
                }
            }
            tmp.push(element);
        }

        if(def_element == def_element_last)
        {
            uncheckFields('lstFieldList');
        }
    }

    //$('#lstFieldList').append(element_String);

    //$('#lstFieldList').multiselect('rebuild');

    $("#lstFieldList").multiselect('dataprovider', tmp);

    $('#lstFieldList').multiselect({
        maxHeight: 200,
        buttonWidth:"100%",
        enableFiltering:true,
        enableCaseInsensitiveFiltering:true,
        /*maxHeight: 200,
        enableCaseInsensitiveFiltering: true,
        //enableFiltering: true,
        onChange: function(option, checked, select) {
            alert('Changed option ' + $(option).val() + '.' + "\nchecked: " + checked + "\nselect: " + select);

            if(checked)
            {
                //uncheckFields('lstFieldList');
            }
            else
            {
                uncheckFields('lstFieldList');
            }
        }*/
    });

    var elem = $('#lstFieldList').next();
    elem.attr('class',(elem.attr('class') + ' open'));
}

可能是什么问题？因为两个文件中存在相同的代码。

如有任何帮助，我们将不胜感激。

提前致谢。

Answer 1

创建数组var tmp = [];

在循环查找选项时创建这样的 json

element = {"label": this.Name,"value":this.id};

并将每个元素推送到tmp

tmp.push(element);

并将这个tmp数组传递给多选

$("#lstFieldList").multiselect('dataprovider', tmp);

并将多选添加到下拉列表中

 $("#lstFieldList").multiselect({
                              maxHeight: 260,
                              buttonWidth:"100%",
                              enableFiltering:true,
                              enableCaseInsensitiveFiltering:true,
                            });
