這個數組哪里問題， 找了半天沒找出來
<script type="text/javascript">
?
?var mysz = ["*","##","***","&&","****","##*"];
?mysz[7]="**";
?
?
?alert=(mysz.length);
?document.write(mysz[0]+<br/>);
?document.write(mysz[7]+<br/>);
?document.write(mysz[2]+<br/>);
?document.write(mysz[4]);
</script>

<br/>要加上'' ? ? ?alert(mysz.length);不要= ??
2017-02-21
alert后邊沒有等號

換行符<br/>要加雙引號
