提交表单时为了防止重复提交的进度条：

function showProcess(isShow, title, msg) {

    if (!isShow) {

        $.messager.progress('close');

        return;

    }

    var win = $.messager.progress({

        title: title,

        msg: msg

    });

}

//Form提交数据

function FormSubmit(formID, urlstr, callback) {

    var formObj = $('#' + formID);

    formObj.form('submit', {

        url: urlstr,

        onSubmit: function () {

            var flag = formObj.form('validate');

            if (flag) {

                showProcess(true, '提示', '正在提交数据...');

            }

            return flag;

        },

        success: function (result) {

            showProcess(false);

            var data = eval('(' + result + ')');

            if (callback)

                callback(data);

            if (!data.success) {//后台操作不成功

                if (data.msg != '') {

                    if (data.msg) {

                        $.messager.alert('提示', data.msg, 'info');

                    }

                    else if (data.errors) {

                        $.messager.alert('提示', data.errors, 'info');

                    }

                }

            }

        },

        onLoadError: function () {

            showProcess(false);

            $.messager.alert('提示', '由于网络或服务器太忙，提交失败，请重试！');

        }

    });

}

调用方法：

FormSubmit('problemForm', 'ProjectProblemDataHandler.ashx?handlerType=AddProblem&Pid=' + node.id, function (data) { //form提交

                            if (data.success == true) {

                                $.messager.alert('提示', "添加成功", 'info', function () {

                                    $('#dialoProblem').dialog('close');

                                    $("#problemForm").form('clear');

                                    $('#problemList').datagrid('reload');

                                });

                            } 

                        });

ProjectProblemDataHandler.ashx页面：

 if (ppqBLL.Insert(ppqModel) > 0)

        {

            context.Response.Clear();

            context.Response.Write("{\"success\":true,\"msg\":\"添加成功\"}");

        }

        else

        {

            context.Response.Clear();

            context.Response.Write("{\"success\":false,\"msg\":\"添加失败\"}");

        }
