推荐答案

function Unique_Name()
{

    var db = database.open("kc-pc\sqlexpress.CWCLondon");
    var dbdata = db.Query("SELECT  email_address FROM call_details WHERE email_address='+ txt_email.Text +';");
    var Email_Id = document.getElementById("MainContent_TabContainer1_TabPanel2_txt_email");
    if (dbdata == Email_Id)
    {
        alert("email id exsist");
    }



}

而不是使用这个你可以使用这个 - < br $> b $ b
