JavaScript 的 break 和 continue 语句
有两种特殊的语句可以在循环中使用： break 和 continue。
—————————————————————————–
Break
break 命令用来打断整个循环， 并继续执行循环后面的代码（如果有的话）。
例子
| <html> <body> <script type=”text/javascript”> var i=0 for (i=0;i<=10;i++) { if (i==3){break} document.write(“The number is ” + i) document.write(“<br />”) } </script> </body> </html> |
结果
| The number is 0 The number is 1 The number is 2 |
———————————————————————
Continue
continue命令将打断当前这次循环，而继续执行下一个循环值。
Example
| <html> <body> <script type=”text/javascript”> var i=0 for (i=0;i<=10;i++) { if (i==3){continue} document.write(“The number is ” + i) document.write(“<br />”) } </script> </body> </html> |
Result
| 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 The number is 10 |
