                                                ?>
			<option value ="" "<?="" $v['userid'] ?>" hassubinfo = "true"><?= $v['name'] ?>

                                            }
                                            ?>

3.js

chose_mult_set_ini("#cse",'<?= $userid;?>'); // 数据初始化权限
//chose_mult_set_ini("#cse",'1,3,4,5'); // 数据初始化权限

/*数据初始化*/
function chose_mult_set_ini(select, selectidstr) {
    var arr = selectidstr.split(','),
    length = arr.length,
    index = '';
    for (i = 0; i < length; i++) {
        index = arr[i];
        $(select + " option[value='" + index + "']").attr('selected', 'selected');
    }
    $(select).trigger("liszt:updated");
}


// 如果是单个：
$("#cse ").get(0).selectedIndex = index; //index为索引值（从0开始）
