今天在用python调用IE获取html网页元素在屏幕上的坐标，当然为了截图啦，(*^__^*) 嘻嘻……

xtop=ie.document.forms[i].elements[j].getBoundingClientRect().top + ie.document.parentwindow.screentop

xleft=ie.document.forms[i].elements[j].getBoundingClientRect().left + ie.document.parentwindow.screenleft

xwidth= ie.document.forms[i].elements[j].getBoundingClientRect().right - ie.document.forms[i].elements[j].getBoundingClientRect().left

xheight= ie.document.forms[i].elements[j].getBoundingClientRect().bottom - ie.document.forms[i].elements[j].getBoundingClientRect().top

forms[i].elements[j].可以用 getElementById(“username”) 代替

然后用python调用delphi截图程序，这样就可以获取网页元素上的截图了，有什么用，嘻嘻，获取图形验证码嘛，然后…

delphi的截图函数:

procedure tform1.snapscreen(a,b,c,d:Integer);

var

bmpscreen:Tbitmap;

jpegscreen:Tjpegimage;

FullscreenCanvas:TCanvas;

dc:HDC;

sourceRect, destRect: TRect;

begin

try

dc:=getdc(0);

fullscreencanvas:=Tcanvas.Create;

fullscreencanvas.Handle:=dc;

bmpscreen:=Tbitmap.create;

bmpscreen.Width :=c-a;

bmpscreen.Height :=d-b;

sourcerect:=rect(0,0,c-a ,d-b );

destrect:= rect(a,b,c,d);

bmpscreen.Canvas.CopyRect(sourcerect,fullscreenCanvas,destrect);

jpegscreen:=Tjpegimage.Create ;

jpegscreen.Assign (bmpscreen);

jpegscreen.CompressionQuality:=100;

jpegscreen.SaveToFile(ExtractFilePath(ParamStr(0))+'tmp.jpg');

FullscreenCanvas.Free;

bmpscreen.Free;

jpegscreen.Free ;

ReleaseDC(0, DC);

except

end;

end;

python调用exe:

os.system(‘jietu.exe ‘+str(xleft+3)+’ ‘+str(xtop+3)+’ ‘+str(xwidth)+’ ‘+str(xheight))

str(xleft+3)等是我的参数，大家应该看得明吧，(*^__^*) 嘻嘻……
