就像标题所说我试图从脚本输出行的开头删除列表编号，我的脚本在下面，并且我的输出示例和我想要的输出

<html>
<head>
<script type="text/javascript">
function textareaToArray(t){
return t.value.split(/[\n\r]+/);
}
function showArray(a){
var msg="";
for(var i=0;i<a.length;i++){
msg+=i+": "+a[i]+"\n";
}
alert(msg);
}
</script>
</head>
<title>
Welcome To ....
</title>
<body>
<center><h1> WELCOME TO .... </h1></center>
</br>
</br>
</br>
<center><form>
<textarea rows="7" cols="60" name="alpha"></textarea>
<br>
<input type="button"
value="show array"
onclick="showArray(textareaToArray(this.form.alpha ))">
</form></center>
</body>
</html>
