提交表单时为了防止重复提交的进度条

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\"}");
        }
