select根据后台的值默认选中

1：首先把值传给input 

　　　　　　　　　　　　　　　　　　　　　　<input type="hidden" id="ManagementRole1" >
                                    <select class="form-control" id="ManagementRole" name="ManagementRole">
                                        <option value="总经理" >总经理</option>
                                        <option value="财务主管">财务主管</option>
                                        <option value="值班经理">值班经理</option>
                                        <option value="出入场员">出入场员</option>
                                        <option value="售货员">售货员</option>
                                        <option value="鞋柜管理人员">鞋柜管理人员</option>
                                        <option value="售票员">售票员</option>
                                        <option value="课程顾问">课程顾问</option>
                                    </select>

然后进行赋值：

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")
