我想知道是否有办法setInterval明确自己.

像这样的东西:

setInterval(function () {
    alert(1);
    clearInterval(this);
}, 2000);

我希望它继续检查,如果它完成它将停止.

我想将文本添加到sql select之前,

我可以做这个:

SELECT (1328724983-time)/60/60 AS status 
FROM voting 
WHERE account = 'ThElitEyeS' AND vid = 1 

这将显示剩余时间.

我想做的是:

SELECT 'Please try after' + (1328724983-time)/60/60 AS status 
FROM voting 
WHERE account = 'ThElitEyeS' AND vid = 1 

有什么方法可以做到这一点吗？

您好,有没有办法同时使用两个sqldatareader？

我正在编写一个程序

我得到错误,因为我同时使用2个读者

代码示例

SqlCommand LoadSilk = new SqlCommand("SELECT silk_own FROM SK_Silk WHERE JID = (SELECT JID FROM TB_User WHERE StrUserID = '"+ comboBox1.Text +"')", Connection);
SqlDataReader SilkReader = LoadSilk.ExecuteReader();
SqlCommand LoadCharacter = new SqlCommand("SELECT * FROM SRO_VT_SHARD.DBO._Char WHERE CharID IN (SELECT CharID FROM SRO_VT_SHARD.DBO._User WHERE UserJID = "+ JID +")", Connection);
SqlDataReader CharacterReader = LoadCharacter.ExecuteReader();

try
{
    SilkReader.Read();
    textBox5.Text = SilkReader[0].ToString();
    Silk = SilkReader[0].ToString();
    dataGridView1.Enabled = true;
    button2.Enabled = true;
    while (CharacterReader.Read()) {
        dataGridView1.Rows.Add(CharacterReader["CharID"].ToString(), CharacterReader["CharName16"].ToString(), CharacterReader["CurLevel"].ToString());
    }
    log(comboBox1.Text + …

我想知道,如果有一种方法可以在另一个类函数中使用类函数而不使用$this->,例如:

class Example {
    public function sayhi() {
        echo "HI";
    }

    public function hi() {
        sayhi();
    }
}

像这样的东西？
