我有一个名为“sort_based_on_this_order附件”的json数组，在这里我需要基于数组进行排序。

代码语言：javascript
复制
var sort_based_on_this_order = ['1666432801510', '1666434048280', '1666433926644', '1666434169913', '1666433101760', '1666434194815', '1666432849037', '1666432764144', '1666432044571', '1666432742444']

sort_based_on_this_order数组包含附件json数组的文件名键值。

我试过了

代码语言：javascript

attachments.sort.forEach(zz => {
                return zz["filename"].match(/\b[0-9]{13}(?=\.[^.]+$)/)
            })

您可以使用以下代码对其进行排序

代码语言：javascript
复制
attachments.sort((a,b) =>{
   let k1 = a.filename.match(/\b[0-9]{13}(?=\.[^.]+$)/)
   let k2 = b.filename.match(/\b[0-9]{13}(?=\.[^.]+$)/)
   let i1 = sort_based_on_this_order.indexOf(k1[0])
   let i2 = sort_based_on_this_order.indexOf(k2[0])
   return i1 > i2 ? 1:-1
})

如果我正确理解，您希望根据attachments数组对sort_based_on_this_order数组进行排序(但是，我没有看到两个数组中的值匹配，所以也许您尝试了其他我无法理解的东西？)

通过对排序中的其他数组使用indexOf，可以根据其他数组进行排序。

attachments.sort((a, b) => {  
  return sort_based_on_this_order.indexOf(a.fileName) - sort_based_on_this_order .indexOf(b.fileName);
});
