javascript - 按 "width x height"模式对数组进行排序

Question

图案看起来像宽度x高度

var formats = [
"900x100",
"900x200",
"1200x200",
"1200x100",
"1100x100",
"1100x200"
];

结果将是:

"1200x200",
"1200x100",
"1100x200",
"1100x100",
"900x200",
"900x100"

首先排序宽度，然后排序高度

通过使用.sort()？

formats.sort(function(a,b){
   // do something
});

Answer 1

给你:

http://jsbin.com/oGEroJI/3/edit?js,console

formats.sort(function(a,b){
   var a = a.split("x");
   var b = b.split("x");
  if (a[0] !== b[0]) {
    return b[0] - a[0]; // by width
  } else {
    return b[1] - a[1]; // by height
  }
});
