JavaScript遍历查找数组中最大值与最小值的方法示例

<script language="javascript"> 
// 查找数组中最小值
function mathMin(arrs){
 var min = arrs[0];
 for(var i = 1, ilen = arrs.length; i < ilen; i+=1) {
 if(arrs[i] < min) {
 min = arrs[i];
 }
 }
 return min;
}
// 代码测试
var rets = [2,4,5,6,7,0,9,10,15,1];
console.log(mathMin(rets));//0
// 在数组中查找最大值
function mathMax(arrs) {
 var max = arrs[0];
 for(var i = 1,ilen = arrs.length; i < ilen; i++) {
 if(arrs[i] > max) {
 max = arrs[i];
 }
 }
 return max;
}
// 代码测试
var rets = [1,4,5,6,7,9,10,15,55];
console.log(mathMax(rets));//55
