使用xml broker, 是delphi 内置的。例:
unit ShowXML;
interface
uses Classes HTTPApp Db DbClient Midas
XMLBrokr WebComp MidItems;
type
TCustomShowXMLButton = class(TXMLButton IScriptComponent)
protected
XMLMethodName: string;
{ IScriptComponent }
procedure AddElements(AddIntf: IAddScriptElements);
function GetSubComponents: TObject;
{ IWebContent implementation }
function ImplContent(Options: TWebContentOptions;
ParentLayout: TLayout): string; override;
end;
TShowXMLButton = class(TCustomShowXMLButton)
public
constructor Create(AOwner: TComponent); override;
published
property Custom;
property Style;
property StyleRule;
property Caption;
property XMLBroker;
property XMLUseParent;
end;
TShowDeltaButton = class(TCustomShowXMLButton)
public
constructor Create(AOwner: TComponent); override;
published
property Custom;
property Style;
property StyleRule;
property Caption;
property XMLBroker;
property XMLUseParent;
end;
implementation
uses sysutils MidProd;
resourcestring
sShowXML = 'Show XML';
sShowDelta = 'Show Delta';
procedure TCustomShowXMLButton.AddElements(
AddIntf: IAddScriptElements);
begin
AddIntf.AddIncludeFile('xmlshow.js');
end;
function TCustomShowXMLButton.GetSubComponents: TObject;
begin
Result := nil;
end;
function TCustomShowXMLButton.ImplContent(Options: TWebContentOptions;
ParentLayout: TLayout): string;
var
Attrs: string;
Intf: ILayoutWebContent;
FormVarName: string;
RowSetVarName: string;
begin
AddQuotedAttrib(Attrs 'NAME' Name);
AddQuotedAttrib(Attrs 'STYLE' Style);
AddQuotedAttrib(Attrs 'CLASS' StyleRule);
AddQuotedAttrib(Attrs 'VALUE' Self.Caption);
AddCustomAttrib(Attrs Custom);
if Assigned(XMLData.XMLBroker) then
begin
FormVarName := XMLData.XMLBroker.SubmitFormVarName;
RowSetVarName := XMLData.XMLBroker.RowSetVarName(nil); // Row row set var name
end;
if not (coNoScript in Options.Flags) then
Result :=
Format(''#13#10
[Attrs RowSetVarName XMLMethodName sXMLReadyVar])
else
Result :=
Format(''#13#10
[Attrs]);
if Assigned(ParentLayout) and ParentLayout.GetInterface(ILayoutWebContent Intf) then
Result := Intf.LayoutButton(Result GetLayoutAttributes);
end;
{ TShowXMLButton }
constructor TShowXMLButton.Create(AOwner: TComponent);
begin
inherited;
DefaultCaption := sShowXML;
XMLMethodName := 'root';
end;
function TCustomShowXMLButton.GetSubComponents: TObject;
begin
Result := nil;
end;
function TCustomShowXMLButton.ImplContent(Options: TWebContentOptions;
ParentLayout: TLayout): string;
var
Attrs: string;
Intf: ILayoutWebContent;
FormVarName: string;
RowSetVarName: string;
begin
AddQuotedAttrib(Attrs 'NAME' Name);
AddQuotedAttrib(Attrs 'STYLE' Style);
AddQuotedAttrib(Attrs 'CLASS' StyleRule);
AddQuotedAttrib(Attrs 'VALUE' Self.Caption);
AddCustomAttrib(Attrs Custom);
if Assigned(XMLData.XMLBroker) then
begin
FormVarName := XMLData.XMLBroker.SubmitFormVarName;
RowSetVarName := XMLData.XMLBroker.RowSetVarName(nil); // Row row set var name
end;
if not (coNoScript in Options.Flags) then
Result :=
Format(''#13#10
[Attrs RowSetVarName XMLMethodName sXMLReadyVar])
else
Result :=
Format(''#13#10
[Attrs]);
if Assigned(ParentLayout) and ParentLayout.GetInterface(ILayoutWebContent Intf) then
Result := Intf.LayoutButton(Result GetLayoutAttributes);
end;
{ TShowXMLButton }
constructor TShowXMLButton.Create(AOwner: TComponent);
begin
inherited;
DefaultCaption := sShowXML;
XMLMethodName := 'root';
end;
{ TShowDeltaButton }
constructor TShowDeltaButton.Create(AOwner: TComponent);
begin
inherited;
DefaultCaption := sShowDelta;
XMLMethodName := 'getDelta()';
end;
另一种方法使用msxml.dll 如下:
....
....
procedure TDHEDForm.OpenBtnClick(Se
{ TShowDeltaButton }
constructor TShowDeltaButton.Create(AOwner: TComponent);
begin
inherited;
DefaultCaption := sShowDelta;
XMLMethodName := 'getDelta()';
end;
另一种方法使用msxml.dll 如下:
....
....
procedure TDHEDForm.OpenBtnClick(Se
