我這樣寫網(wǎng)頁(yè)崩了………………
<script type="text/javascript">
? ? var mynum =6;//mynum初值化數(shù)值為6
do
{
document.write("數(shù)字:"+mynum+"<br/>");
mynum=mynum-1;
}
while( ?mynum=6 ? ? )
</script>

不能等于6，會(huì)出現(xiàn)死循環(huán)，然后網(wǎng)頁(yè)就爆炸了，人家定義var mynum =6，然后下邊又mynum=mynum-1;，說(shuō)明要輸出6以下的數(shù)，這樣寫就好了while(mynum >= 1)

條件永遠(yuǎn)為真- -他就會(huì)一直循環(huán)下去當(dāng)然卡死你啦。還有“=”是賦值，“==”才是等于。

while( ?mynum=6 ? ? )-------->while( ?mynum==6 ? ? ) 賦值符號(hào)

你的條件寫成賦值符號(hào)了，改成while(mynum==6)
