JS求从1开始第28个能被7和3整除的整数

利用JS求从1开始第28个能被7和3整除的整数，该如何实现呢？这里我们考虑用while循环来做，循环次数设定5000次，5000次以内绝对可以找到这个数，当找到这个数的时候，我们需要停止循环，break。将需求转化为代码：<script>//求从1开始第28个能被7和3整除的整数vari=1; varjishu=0; //设定5000次循环while (i<=5000) { i....

JS求1-100之间除了能被7整除之外的其他整数和

JS求1-100之间除了能被7整除之外的其他整数和。看到这样一个需求，肯定是用for循环来做，但用我们之前文章所将的内容无法完成，这里需要增加一个continue ，即退出当前次的循环继续执行剩余次数循环。将需求转化为代码：<script>// 求1-100之间除了能被7整除之外的其他整数和varsum=0; for (vari=1; i<=100; i++) { if ....

利用JS求1-100之间所有能被3整除的数字之和

利用JS求1-100之间所有能被3整除的数字之和，这需要怎么实现呢？我们需要进行分析，判断是否可以利用for循环来实现，答案是可以的。我们将需要转化为代码：要求是能被3整除的数字，所以条件表达式这样写即可 i % 3 == 0。<script>// 求1-100之间所有能被3整除的数字之和varresult=0; for (vari=1; i<=100; i++) { if (....

js 整除，取整数，去模

因为js里，所有的数都是浮点型，所以用 num1/num2 得出的数是浮点数，而非整数。这里与java 和 .net不同。 1 varInt=parseInt(num1/num2); //可以获得整数部分，小数部分丢失 2 为了能比较简单的得到整数部分，js 有内置的方法 Math.round(num1/num2) //取整数部分（四舍五入） Mat...
