问题来源: http://www.cnblogs.com/del/archive/2008/04/02/1131232.html#1133889
答案: WebBrowser1.OleObject.Document.ParentWindow.变量名;
譬如有这样一个页面(lancernig 举的例子), 如何提取其中的 pvs 呢: <html> <head> <title>测试页</title> <script language="javascript" type="text/javascript"> var smoneyval = "0"; var cival = "0"; //var ssum = 0; var smoneys = "0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0" ; var cis = "0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0"; var pvs = "140.74,142.51,106.64,86.39,77.71,52.48,38.90,28.76,25.59,19.23,17.23,14.24,12.21,12.00,12.33,12.33,13.55,14.28,19.80,24.34,32.21,38.80,46.47,74.96,94.80,117.13,174.36,269.35"; var smoneys_Array = smoneys.split(","); var cis_Array = cis.split(","); var pvs_Array = pvs.split(","); </script> </head> <body> ... </body> </html>
假定是把页面保存在 'c:\temp\test.htm', 测试代码如下:

type
TForm1 = class(TForm)

{提取 smoneys}
s := WebBrowser1.OleObject.Document.ParentWindow.smoneys;

ShowMessage(s);
