I would like to know if it is possible to loop through all the textboxes on a page and insert a value into each one starting with the number 1 and going up by +1. There are over 150 textboxes on this page and they are not in an array and I would not like to rename them one by one.. :-(

Thanks for any help....

  • "rename" or "set a value", what should it be? – Tomalak Commented May 27, 2011 at 21:49

Reset to default 5 
var input = document.getElementsByTagName("INPUT");
var j = 0;

for (var i = 0; i < input.length; i++) {
  if (input[i].type == "text") {
    input[i].value = ++j;
  }
}

function FillTextBoxes()
{
    var tbs = document.getElementsByTagName("input");
    var valCount = 0;

    for (var i = 0 ; i < tbs.length ; i++)
    {
        if (tbs[i].type == "text")
        {
            tbs[i].value = ++valCount;
        }
    }
}

window.onload = FillTextBoxes;

Try this out:

$('input[type="text"]').each(function(index) {

    $(this).val(index);

})

Per the request of some, for pleteness' sake, the above requires the JavaScript library, jQuery. You can reference it like so:

<script src="//ajax.aspnetcdn./ajax/jQuery/jquery-1.6.1.js"></script>

If you aren't using <!DOCTYPE html> you can include the type="text/javascript" attribute.
