JavaScript中的break和continue语句介绍
Break 语句
break 语句用于跳出 switch() 语句。
break 语句可用于跳出循环。
break 语句跳出循环后,会继续执行该循环之后的代码(如果有的话)
for (i=0;i<10;i++)
{
if (i==3)
{
break;
}
x=x + "The number is " + i + "<br>";
}
运行结果:
The number is 0
The number is 1
The number is 2
Continue 语句
continue 语句中断循环中的迭代,如果出现了指定的条件,然后继续循环中的下一个迭代。
该例子跳过了值 3:
for (i=0;i<10;i++)
{
if (i==3) continue;
x=x + "The number is " + i + "<br>";
}
The number is 0
The number is 1
The number is 2
The number is 4
The number is 5
The number is 6
The number is 7
The number is 8
The number is 9
