Using first letter of field value within URL parameters

[perdman]

I am trying to use Javascript to call the value of a field (First_Name),

Then trim this field down to the first letter of field value,

Then write the result back to a hidden database field.

If I can get this accomplished, I will then be able to use the field value within URL parameters to call specific records, whose First_Name field starts with the specified letter.

I am using the following code, with no luck yet:

function getfirst()

{

var firstletter = document.getElementById("InsertRecordFirst_Name").value;

var fl = (firstletter.charAt(0)).value;

document.getElementById("InsertRecordfl").value=fl;

}

document.getElementById("caspioform").onsubmit=getfirst;

Anyone have any suggestions?

Thanks in advance.

The charAt() method returns the character at the specified index in a string.

You should replace charAt(0).value at charAt(0). Add this script to HTML Block. It must be the last element on the page.

<script type="text/javascript" language="JavaScript">
function getfirst()
{
var firstletter = document.getElementById("InsertRecordFirst_Name").value;
document.getElementById("InsertRecordfl").value = (firstletter) ? (firstletter.charAt(0)) : '';
}
document.getElementById("caspioform").onsubmit=getfirst;
</script>

Hope this helps
