JavaScript break 和 continue 语句
有两种特殊的语句可用在循环内部break 和 continue
Break
break命令可以终止循环的运行然后继续执行循环之后的代码(如果循环之后有代码的话)
实例
<html>
<body>
<scripttype=text/javascript>
vari=
for(i=;i<=;i++)
{
if(i==){break}
documentwrite(Thenumberis+i)
documentwrite(<br/>)
}
</script>
</body>
</html>
结果
The number is
The number is
The number is
Continue
continue命令会终止当前的循环然后从下一个值继续运行
