sort函数在JavaScript中用于对数组中的元素进行排序。它接受一个可选的参数,即一个名为compare的函数,用于定义排序顺序。如果没有提供compare函数,sort函数将按照字符串的Unicode编码顺序进行排序。 compare函数应该接受两个参数,即要比较的两个元素。如果第一个元素应该在第二个元素之前,compare函数应该返回一个负数...
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: 1,3,25...

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] ...

Sort Compare Function Sorting alphabetically works well for strings ("Apple" comes before "Banana"). But, sorting numbers can produce incorrect results. "25" is bigger than "100", because "2" is bigger than "1". You can fix this by providing a "compare function" (See examples below). ...
If numbers are sorted as strings, "25" is bigger than "100", because "2" is bigger than "1".Because of this, the sort() method will produce incorrect result when sorting numbers.You can fix this by providing a compare function:
