JS-sort排序

Posted 2020-08-19

var arr = [ ‘c‘, ‘d‘, ‘a‘, ‘e‘ ];
// arr.sort();
// alert( arr );

var arr2 = [ 4,3,5,5,76,2,0,8 ];
// arr2.sort();
// alert( arr2 );

arr2.sort(function ( a, b ) {
    return a - b;
});

// alert( arr2 );

var arrWidth = [ ‘345px‘, ‘23px‘, ‘10px‘, ‘1000px‘ ];

arrWidth.sort(function ( a, b ) {
    return parseInt(a) - parseInt(b);
});

alert( arrWidth );
