select根據后台的值默認選中

1：首先把值傳給input 

　　　　　　　　　　　　　　　　　　　　　　<input type="hidden" id="ManagementRole1" >
                                    <select class="form-control" id="ManagementRole" name="ManagementRole">
                                        <option value="總經理" >總經理</option>
                                        <option value="財務主管">財務主管</option>
                                        <option value="值班經理">值班經理</option>
                                        <option value="出入場員">出入場員</option>
                                        <option value="售貨員">售貨員</option>
                                        <option value="鞋櫃管理人員">鞋櫃管理人員</option>
                                        <option value="售票員">售票員</option>
                                        <option value="課程顧問">課程顧問</option>
                                    </select>

然后進行賦值：

modal.find('.modal-body input#ManagementID').val(management.managementID);
            modal.find('.modal-body input#ManagementName').val(management.managementName);
            modal.find('.modal-body input#ManagementRole').val(management.managementRole);
            modal.find('.modal-body input#ManagementRole1').val(management.managementRole);
            modal.find('.modal-body input#ManagementPhone').val(management.managementPhone);
            modal.find('.modal-body input#ManagementPass').val(management.managementPass);
            modal.find('.modal-body input#pageindex').val(pageindex);

            var role=$("#ManagementRole1").val()
            $("#ManagementRole option[value='"+role+"']").attr("selected","selected")
