each loop to (for loop or while loop)

Question

Im displaying all the files from upfiles array using each loop in jquery,

CODE using each loop:

$(upfiles).each(function(index3, filelist) {
    alert(filelist.name); //displays filename
    alert(filelist.size); //displays filesize
}

how can I do the same thing using for loop or while loop :

// **CODE I have tried :**
var i;
for(i=0;i<=upfiles.length;i++)
{
   alert(upfiles[i][name]);  // trying this way but not displaying
}

Use alert(upfiles[i]["name"]) or alert(upfiles[i].name)

Try:

for(var i = 0; i < upfiles.length; i++)
{
   alert(upfiles[i].name); // note the removal of the [] brackets
}

Special note: when using this for-loop you should loop while the variable i is less than the length of the array upfiles.length and not less or equal, because the array is 0-based, meaning you'll get an out-of-bound exception if i equals the length of the array.

Try to pass the key value as quoted string while using bracket notation,

 alert(upfiles[i]['name']);

Full code:

for(var i=0;i<upfiles.length;i++)
{
   alert(upfiles[i]['name']);
}
