Question

First, how do you append data to the end of a variable in Javascript? I know for PHP you use:

$foo = "bar";
$foo.= "bar2";

Next, I can get the following to work for one form field:

var test = document.form1.option1.value;

However, how would I go about doing this with a for loop whilst appending each iteration onto the end of the variable? For example (where XXX is the loop variable i):

for(i=0; i<10; i++){
    test.= document.form1.optionXXX.value;
}

Basically, I need all the data from a random set of form fields that can range anywhere from option1 to option20. Thanks.

Answer 1

var test = "";
for (var i=0; i<10; i++){
    test += document.form1["option" + i].value;
}
