    Try that for a start

    var len= document.getElementsByTagName('input').length; 
// add that you want the number of element
// Change 'name' for 'input' when using 'name' you are looking for <name in the HTML
// if you want the element with the name ABC use getElementsByName()

var str1='';
for(i=0;i<=len;i++)
{
    var str=(subscribe[i].value);

    str1=str1+str; 
 }
  alert(str1);
