好吧，实际上，您只需要$ .each即可获取所有值，它将帮助您

<div > <select id="drp_Books_Ill_Illustrations"  name="drp_Books_Ill_Illustrations" multiple="">     <option value=" ">No illustrations</option>     <option value="a" selected>Illustrations</option>     <option value="b">Maps</option>     <option value="c" selected>selectedPortraits</option> </select>    </div><div >        <select id="drp_Books_Ill_Illustrations1"  name="drp_Books_Ill_Illustrations" multiple=""> <option value=" ">No illustrations</option> <option value="a">Illustrations</option> <option value="b">Maps</option> <option value="c">selectedPortraits</option>        </select></div><button >Get Value</button><button  > Set  value </button><div >        <select id="drp_Books_Ill_Illustrations2"  name="drp_Books_Ill_Illustrations" multiple=""> <option value=" ">No illustrations</option> <option value="a" selected>Illustrations</option> <option value="b">Maps</option> <option value="c" selected>selectedPortraits</option>        </select></div><div >        <select id="drp_Books_Ill_Illustrations3"  name="drp_Books_Ill_Illustrations" multiple=""> <option value=" ">No illustrations</option> <option value="a">Illustrations</option> <option value="b">Maps</option> <option value="c">selectedPortraits</option>        </select></div><button >Get Value</button><button  > Set  value </button>

剧本：

 var selectedValues = new Array();    selectedValues[0] = "a";    selectedValues[1] = "c";$(".getValue").click(function() {    alert($(".leaderMultiSelctdropdown").val());});$(".setValue").click(function() {   $(".Books_Illustrations").val(selectedValues);});$('#drp_Books_Ill_Illustrations2, #drp_Books_Ill_Illustrations3').select2();$(".getValue1").click(function() {    alert($(".leaderMultiSelctdropdown").val());});$(".setValue1").click(function() {    //You need a id for set values    $.each($(".Books_Illustrations"), function(){ $(this).select2('val', selectedValues);    });});
