怎樣去掉圖片鏈接點擊后，圖片周圍的虛線
<script>
myWin=window.open("about:blank","","width=200,height=160");
myWin.moveTo(screen.width/2-100,screen.height/2-80);
</script>
function test(t) {
for (var i=0; i<t.rows.length; i++)
for (var j=0; j<t.rows[i].cells.length; j++)
t.rows[i].cells[j].bgColor = t.rows[i].cells[j] == event.srcElement ? 'red' : '';
}
</script>
<table width="300" cellspacing="1" bgcolor="black" onClick="test(this)">
<tr bgcolor="white" height="20"><td> </td><td> </td><td> </td></tr>
<tr bgcolor="white" height="20"><td> </td><td> </td><td> </td></tr>

有三個單選框，
<input type=radio name=1>222
<input type=radio name=2>222
<input type=radio name=3>222
怎么樣使選中第一個后才能選擇下面兩個中的一個。
function change(radobj){
var obj = document.getElementsByName("radio2");
for(i=0;i<obj.length;i++){
obj[i].disabled = !radobj.checked;
}
}
</script>
<input type=radio name="radio1" onclick=change(this)>222
<input type=radio name="radio2" disabled>222
<input type=radio name="radio2" disabled>222
