我只有一个下拉列表,例如zone,当我选择zone时,他所在的zone下的多个状态数据将被放入多选表单字段中。
$("#ZoneId").on("change", function (event) {
$.ajax({
async:true,
beforeSend:function (XMLHttpRequest) {
$('#ZoneId').attr('disabled', true);
},
complete:function (XMLHttpRequest, textStatus) {
$('#ZoneId').attr('disabled', false);
},
data:$("#ZoneId").closest("form").serialize(),
dataType:"html",
type:"post",
url:REQUEST_URL+"State/get_state_by_zone"
success:function (data, textStatus) {
//$("#my_multi_select1").empty();
//$('#my_multi_select1').multiselect('destroy');
$("#my_multi_select1").append();
//var prePopulate = JSON.parse(data);
$.each(data, function (i, state) {
$("#my_multi_select1").append('<option value="' + i + '">' + state + '</option>');
});
$("#my_multi_select1").attr('multiple', 'multiple');
$("#my_multi_select1").multiselect('rebuild');
//$("#my_multi_select1").multiselect('refresh');
},
});
return false;
});
