数组中如何取最低价格？

Question

取出来最低价是500，但是想要取出来是500.00，求解？

var price = ["1000.00","2000.00","500.00","4000.00"]
Math.min.apply(Math,price)

Answer 1

var price = ["1000.00","2000.00","500.00","4000.00"]
Math.min.apply(Math,price).toFixed(2);

Math.min会将字符串转换为数字，也就说500.00会转为500
所以需要加一个toFixed(2)就能得到你要的结果

Answer 2

var price = ["1000.00","2000.00","500.00","4000.00"]
Math.min.apply(null,price).toFixed(2);

Answer 3

price.sort((a,b) => b-a)[price.length - 1]
这个答案会改动原有数组。

Answer 4

var price = ["1000.00","2000.00","500.00","4000.00"]
function getMin(total, num) {
    return +total<num?total:num;
}
price.reduce(getMin);

Answer 5

也可以先排序，再取值
