说明:sort 方法内如果不传参数，则是比较数组内元素的 ASCII 字符编码的值，即每次都会调用元素的 toString() 转换成字符串，按ASCII字符编码值进行比较若想按照其他方式进行排序，则需要传入比较函数（sort 内的参数），比较函数需要返回值，当函数返回值为1的时候就交换两个数组项的顺序，否则就不交换 按照 ASCII ...
letnumbers = [0,1,2,3,10,20,30];numbers.sort(function(a , b){if(a > b)return1;if(a < b)return-1;return0;}); console.log(numbers); 输出: [0,1,2,3,10,20,30] 或者您可以使用箭头函数语法定义比较函数...
vararr = [ 1, 3, 25]; arr.sort(compare);//函数名是对象的引用,所以只写名字就行。alert(arr);functioncompare(num1, num2) {vartemp1 =parseInt(num1);vartemp2 =parseInt(num2);if(temp1 <temp2) {return-1; }elseif(temp1 ==temp2) {return0; }else{return1; } } 结果: 1,3,...

JavaScript手册 | JS Array 对象中的sort() 方法 [ sort() 方法用于对数组的元素进行排序。 排序顺序可以是字母或数字,并按升序或降序。 默认排序顺序为按字母升序。 注意:当数字是按字母顺序排列时"40"将排在"5"前面。 使用数字排序,你必须通过一个函数作为参数来调用。
JavaScript中数组的sort()方法主要用于对数组的元素进行排序。 一、原理: arr.sort((m,) => { ... return (number); } sort内的函数返回值小于0, m排在n前面; 返回值等于 0, m,n相等顺序无关要紧; 返回值大于 0, m排在n后面; 1. 2.
