procedure TForm1.WebBrowser1BeforeNavigate2(ASender: TObject;
const pDisp: IDispatch; var URL, Flags, TargetFrameName, PostData,
Headers: OleVariant; var Cancel: WordBool);
var
myurl,tstr:string;
Stpos,len:Integer;
begin
if WebBrowser1.ReadyState=READYSTATE_COMPLETE then  //判斷頁面是否加載完成
begin
myurl:=string(URL);                 //獲取URL
Stpos:=LastDelimiter('#',myurl);    //獲取URL中 #向後的字符個數
len:=Stpos-1;                       //字符長度減一
tstr:=Copy(myurl,stpos+1,len);      //組合過濾後子字符
//判斷用戶點擊了那個鏈接
if tstr='caigou' then
