为什么我的confirm弹框总是不弹出来？
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>confirm</title>
<script type="text/javascript">
function rechpe(){
var confirm=confirm("Are you a boy?");
if(confirm==true){
document.write("i am boy");
}else{
document.write("i am girl");
}
}
</script>
</head>
<body>
<input name="button" type="button" onClick="rechpe()" value="点击我，弹出确认对话框" />
</body>
</html>
