解决方案 »

  1.   

    一个radio不能实现开关功能,使用checkbox比较合适
      

  2.   

    超级大笨狼,灌水专用脚本:
     <SCRIPT LANGUAGE="JavaScript">
      Draw_Triangle(40);
      Draw_Line(40);
    function Draw_Triangle(line)
    {
    var chars="";
    for(i=1;i<=line;i++)
    {
    var blank="";
    var star="";
    for(j=0;j<i;j++)
    {
    star +="*&nbsp;" ;

    for(k=0;k<(line-i);k++)
    {
    blank +="&nbsp";  

    chars+=blank + star + "<br/>";

    }
    document.write(chars);
    }function Draw_Line(line)
    {
    var chars="";
    for(i=1;i<=line;i++)
    {
    var blank="";
    var star="";
    for(j=0;j<line/2;j++)
    {
    star +="*&nbsp;" ;

    for(k=0;k<line/2;k++)
    {
    blank +="&nbsp";  

    chars+=blank + star + "<br/>";

    }
    document.write(chars);
    }
     </SCRIPT>
