如何以降序（反向）顺序访问javascript数组？

Question

var content1    =  eval ("(" + data + ")");
var content    =  content1.Data;  
for (property in content) {console.log(content[property].name); }

I need to access this content array descending order. now it's work fine but not the way I want.It print first element in the array.

I want to print last element in first place. MySQL gives descending order result set but this for loop print first id element in first place.

You can either do from reverse length.

or

You can just reverse() the array

 var array = [1,2,3]; for (var item of array.reverse()) { console.log(item); } console.log(" "); var other = ["first", "second", "third"]; for (var i = other.length - 1; i >= 0; i--) { console.log(other[i]); }
