Ok. me again I know I know.

I have input boxes named name[] to make them an array.

How would I add the values of the array to get a total.

And there will never be the same number in the array.

sometimes there may be 3 text boxes sometimes 8.

in php I know I can get a count of values in the array. but not sure on in javascript.

To total the values in an array loop through the array adding each value to a total variable

CODE

var total = 0;
for(var i = 0; i < myArray.length; i++){
 total += myArray[i];
}

of course if there is a change there will be string values in there (if say you're pulling them out of input fields) you will need to verify what you are adding together are both numbers with parseFloat or parseInt.

CODE

var total = 0;
for(var i = 0; i < myArray.length; i++){
 var thisVal = parseInt(myArray[i]);
 if(!isNaN(thisVal)){
  total += thisVal;
 }
}
