Javascript基础教程之break和continue语句

<script language="javascript">
var aNumbers = new Array();
var sMessage = "你输入了:<br>";
var iTotal = 0;
var vUserInput;
var iArrayIndex = 0;
do{
    vUserInput = Number(prompt("输入一个数字，或者'0'退出","0"));
    if(isNaN(vUserInput)){
        document.write("输入错误，请输入数字，'0'退出<br>");
        break;        //输入错误直接退出整个do循环体
    }
    aNumbers[iArrayIndex] = vUserInput;
    iArrayIndex++;
}while(vUserInput != 0)        //当输入为0（默认值）时退出循环体
//for循环遍历数组的常用方法
for(var i=0;i<aNumbers.length;i++){
    iTotal += Number(aNumbers[i]);
    sMessage += aNumbers[i] + "<br>";
}
sMessage += "总数:" + iTotal;
document.write(sMessage);
</script>
