javascript - 如何使用 bootstrap-select 动态设置多个值

Question

我需要使用 bootstrap-select 插件动态设置多个值。我在下面提供我的代码。

<div class="row">
<div class="col-md-12">
<div class="form-group">
<div class="col-md-2" style=" width: 13.3%; max-width: 100%;">
<label for="" class="control-label" style="text-align:left;">Menu:</label>
</div>
    <div class="col-md-10 well" style="max-height:220px;overflow-y: auto;max-width: 100%;width: 85%;">
<div class="row" id="examMenuGroup"></div>
            </div>
        </div>
    </div>
</div>

var options = "<div class='col-md-12'><label class='checkbox-inline'><input type='checkbox' id='allmenu' onclick='checkAll(this.id)'><strong>Select All</strong></label></div></br>";
    var menuArr=[{'menu_name':'Document','id':1},{'menu_name':'Profile','id':2},{'menu_name':'Fee','id':3},{'menu_name':'Communication','id':4}];
    $.each(menuArr,function(i,data)
    { 
        options = options + "<div class='col-md-2'><label class='checkbox-inline'><input type='checkbox' name='chkmenu[]' data-label='"+data.menu_name+"' id='chkMenu"+data.id+"' value='"+data.menu_name+"'>"+data.menu_name+"</label></div>";
    });
    $('#examMenuGroup').html("");   
    $('#examMenuGroup').append('<%=Encoder.encodeForJS('+options+')%>');
    $('#examMenuGroup').html(options)
    .selectpicker('refresh');

我在这里设置了 bootstrap-select 插件中的 check box 值。但在这里我的要求是我需要设置值 (i.e-Document,Profile) 使用一些点击事件意味着当用户点击任何按钮时这些 (i.e-Document,Profile) 值将在复选框中动态选择。

要设置多个值，需要将值作为数组传递。要清除值，请传递 "" 或 null 作为值。

$(document).ready(function(){
    $(".add").click(function(){
        var options =  $(this).data("options").split(",");
        $(".selectpicker").val(options).selectpicker("refresh"); //The following one can also be used. It handles refresh internally.
        //$(".selectpicker").selectpicker("val",options);
    });
});
