58.动态改变字体的大小
function doZoom(size)
{
document.getElementById('zoom').style.fontSize=size+'px'
}
function aa()
{
var newWin=window.open(url);
newWin.document.form1.text1.value=value1;
}改变弹出窗口上域的属性
opener.document.form2.text2.value=value2;改变父窗口的域的值 59.判断是何种浏览器
var name = navigator.appName;
if (name == "Microsoft Internet Explorer")
alert("IE");

function JM_cc(bb)
{
var ob=eval("document.form1."+bb);
ob.select();
js=ob.createTextRange();
js.execCommand("Copy");
}// 62.java中建立数据库连接取数据
public void init()
{
String url="jdbc:odbc:javadata";
try
{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con=DriverManager.getConnection(url,"sa","");//mssql database user SA and password
DatabaseMetaData dma=con.getMetaData();
System.out.println("Connect to"+dma.getURL());
System.out.println(";Driver "+dma.getDriverName());
System.out.println(";Version "+dma.getDriverVersion());
System.out.println("");
Statement stmt=con.createStatement();
ResultSet rs=stmt.executeQuery("select * from company.dbo.TB_NAME where number=1");//Sql
rs.next();
String dispresult=rs.getString("name");
System.out.println(dispresult);// Instead,you can display it in Paint() or use AWT etc.
rs.close();
stmt.close();
con.close();
}
catch(SQLException ex)
{
System.out.println("!!!SQL Exception !!!");
while(ex!=null)
{
System.out.println("SQLState:"+ex.getSQLState());
System.out.println("Message:"+ex.getMessage());
System.out.println("Vendor:"+ex.getErrorCode());
ex=ex.getNextException();
System.out.println("");
