It's worth noting that if Python doesn't terminatewhileloops, they can loop endlessly. Therefore, when relying on abreakstatement to end awhileloop, you must ensure Python will execute yourbreakcommand. Let's consider our previous example, where we wrote a script to find the first ten multi...
<script type="text/javascript"> for(var i=1;i<=10;i++){ if(i==6) break; document.write(i); } //输出结果:12345 </script> continue语句: continue语句和break语句相似。所不同的是,它不是退出一个循环,而是开始循环的一次新迭代。

从unsyntactic可以看出来,这个报错其实是异步导致的。 使用jsonp请求的时候不知道它是异步的,于是我在for循环内发送jsonp请求。而我也在promise对象的then方法内写了continue,由于promise是异步的,触发break的时候循环可能已经执行完了,所以break与continue就不能用(在then方法中)了。
练习: 打印1-100之间的乘积 计算1000以内所有不能被7整除的整数之和 计算出1-100之间不能被3整除的整数的和,和大于(或等于)2000的数字 break立即退出循环 continue立即退出当前循环,但退出循环后会从循环的顶部继续执行 练习: 求200-300之间所有奇数的和,用continue实现 求200-300之间第一个能被7整数的数...
