Bootstrap-selectpicker多选赋值

                    <select id="sela" class="selectpicker form-control"  multiple>
                        <option value="sel_Fff">FX</option>
                        <option value="sel_aaa">TB</option>
                        <option value="sel_Other">其他</option>
                    </select>

$("#sela").selectpicker("val",['sel_Fff','sel_aaa']);

单选赋值或者清空等功能官网的method里都是有说明的
