当比较 40 和 100 时,sort()方法会调用比较函数 function(40,100)。 该函数计算 40-100(a - b),然后返回 -60(负值)。 排序函数将把 40 排序为比 100 更低的值。 您可以使用下面的代码片段来测试数值和字母排序: Sort Alphabetically Sort Numerically <pid="demo"> varpoints ...

Array.sort 默认的行为是这样的. 首先把所有的值强转成 string, 然后进行 string comparison. 第二题的中文字, 因为 string comparison 是比 Unicode 的号码, 而不是依据汉语拼音, 所以顺序就不对了. ['差' , '八', '阿'].map(v => v.charCodeAt(0));//[24046, 20843, 38463] ...

在javascript中实现多维数组、对象数组排序,基本上都是用原生的sort()方法,用于对数组的元素进行排序。 其基本的用法就不说了,先看个简单的排序例子: //Sort alphabetically and ascending: var myarray=["Bob", "Bully", "Amy"] myarray.sort() //Array now becomes ["Amy", "Bob", "Bully"] 数组直接...
We can sort data alphabetically or numerically. The sort key specifies the criteria used to perform the sort. It is possible to sort objects by multiple keys. For instance, when sorting users, the names of the users could be used as primary sort key, and their occupation as the secondary ...
// sort alphabeticallyconstname=['Shoaib','Mehedi','Alex','Jane'];constarr=[1,30,4,21,100000];name.sort();console.log(name);// sort numericallyarr.sort(function(a,b){returna-b;});console.log(arr); 4、字符串反转 字符串反向是一个基本而普遍的问题。在这里,我将展示一些可能的方法。
