Access Textbox value in Content PlaceHolder thru Javascript

Hi Experts,
I have a aspx page which uses a Master Page. I have a text field inside the Content Placeholder. I want to change the data to Uppercase whenever it is entered thru a Javascript. The question is, how would I access the textfield in Javascript? Please let me know. Thank you very much in advance.

Thank you skullnobrains,
I tried your line and got the below error message. In fact the javascript fails and gives me this error. When I remove the .value from the line, I get the 'null' value. But, javascript still runs. Any idea? Thank you again for your help.

I am testing this line
-------------------------------------------
var fname = document.getElementById('txtFName').value;

Error Message
---------------------------------
Microsoft JScript runtime error: Object required

Hi skullnobrains and Sar1973, I really appricate your answers. But I don't know why it did not work for me. I am not experts on this either. I am really sorry, but I provided my reply honestly. Please look below for my explanation. Hope that helps.

Here is what I did in my page load.

txtDate.Attributes.Add("onblur", "return ValidDate(this)");

This is my aspx program.

<script type="text/javascript">

function checkdate(input) {

var Day = input.value.split("/")[0];
var Month = input.value.split("/")[1];
var Year = input.value.split("/")[2];

input.value = Day + "/" + Month.toUpperCase() + "/" + Year;
}

</script>
