我只是想如果password等于usename的前4位就转google,否则转yahoo, TNND, 好像if语句不起作用?怎么回事?谢谢!

解决方案 »

  1.   

    我把语句if (username.com == password)改成if (false),可他还是转到google,????
      

  2.   

    我用的是vs2005,当debug时,必须refresh一下页面才行!气死我了!!!
      

  3.   

    if (username == password)
      

  4.   

    username.com什么意思？
    直接if (username == password)不就好了
