Question

A dump question:

var arr = ['top', 'dir1', 'dir2', 'dir3' .. goes];

How can I get a result like below after looping this array?

result_string => #top, #top/dir1, #top/dir1/dir2, #top/dir1/dir2/dir3

btw is there a problem having a slash for jQuery selectors,

Thanks.

Try this.

var arr = ['top','dir1','dir2','dir3'];

for(var i=0,j=arr.length;i<j;i++)
{
   arr[i] = i  > 0 ? arr[i-1] + '/' + arr[i] : '#'+arr[i];
}

alert(arr.join(','))
