你的全部符號(hào)都使用了中文字符，要重新輸入一遍，括號(hào)也是使用英文的，有些地方存在留空
正確版：
<pre>
<!DOCTYPE?HTML>
<html>
<head>
<meta?http-equiv?="Content-Type"?content?=“text/html;?charset?=?utf-8”?/>
<title>確認(rèn)</title>
??<script?type?="text/javascript">
????function?rec(){
????????var?mymessage?=?confirm("你是女士嗎？");
????????if?(mymessage?===?true)
????????{
????????????document.write("你是女士！");
????????}
????????else
????????{
????????????document.write("你是男人!");
????????}
????}????
??</script>
</head>
<body>
????<input?name?="button"?type?="button"?onClick?='rec()'?value?="點(diǎn)擊我，可以確認(rèn)確認(rèn)"?/>
</body>

function rec(){

????mymessage;? ? ? 加句觸發(fā)
??? if(mymessage==true)

?var mymessage=confirm("你是女士嗎?")? ? ?;
加引號(hào)
