問(wèn)一下，我是哪里錯(cuò)了啊？
<!DOCTYPE?HTML>

????<head>
????????<meta?http-equiv="Content-Type"?content="text/html;?charset=utf-8"?/>
????????<title>函數(shù)調(diào)用</title>
????????<script?type="text/javascript">
????????????function?contxt()?//定義函數(shù)
????????????{
????????????????alert("哈哈，調(diào)用函數(shù)了!");
????????????}

</html>運(yùn)行了之后沒(méi)問(wèn)題，但是它不讓我通過(guò)，是不是哪里寫得不標(biāo)準(zhǔn)？
