js中,如何返回两个数的商的整数和余数部分? 如: num1:100 ,num2:12 var num = parseFloat(100/12); //值: 8.333333333333334 那么如何返回整数/余数,返回结果 8/4 js的方法 //计算件数(产品数量/包装数量) var JsPieceNum = function(num1,num2){ var pieNum = parseFloat(num1/num2); var result=""; //判断是否为浮点数(100

Math.random():获取0~1随机数 Math.floor() method rounds a number DOWNWARDS to the nearest integer, and returns the result. (小于等于 x,且与 x 最接近的整数.)其实返回值就是该数的整数位:Math.floor(0.666) --> 0Math.floor(39.2783) --> 39 所以我们可以使用Math.floor(Math.random())去获取你想要的一

对于整数区间获取随机整数: m,n均为整数,且n>m. 获取[m,n)区间内的随机整数: 1 var aNumber = (n - m) * Math.random() + m; 2 var result = Math.floor(aNumber); 获取获取[m,n]区间内的随机整数: 1 var aNumber = (n+1- m) * Math.random() + m; 2 var result = Math.floor(aNumber); 获取对于区间(m,n)的随机整数,JS代码:
<script> function GetRandomNum(Min,Max){ var Range = Max - Min; var Rand = Math.random(); return(Min + Math.round(Rand * Range)); } var num = GetRandomNum(1,10); alert(num); </script> var chars = ['0','1','2','3','4','5','6','7
