This is probably very simple, but could somebody tell me how to get the cursor blinking on a text box on page load?

Sure:

<head>
    <script src="jquery-1.3.2.min.js" type="text/javascript"></script>
    <script type="text/javascript">
        $(function() {
            $("#myTextBox").focus();
        });
    </script>
</head>
<body>
    <input type="text" id="myTextBox">
</body>

HTML:

  <input id="search" size="10" />

jQuery:

$("#search").focus();

Set focus on the first text field:

 $("input:text:visible:first").focus();

This also does the first text field, but you can change the [0] to another index:

$('input[@type="text"]')[0].focus();

Or, you can use the ID:

$("#someTextBox").focus();

Think about your user interface before you do this. I assume (though none of the answers has said so) that you'll be doing this when the document loads using jQuery's ready() function. If a user has already focussed on a different element before the document has loaded (which is perfectly possible) then it's extremely irritating for them to have the focus stolen away.

You could check for this by adding onfocus attributes in each of your <input> elements to record whether the user has already focussed on a form field and then not stealing the focus if they have:

var anyFieldReceivedFocus = false;

function fieldReceivedFocus() {
    anyFieldReceivedFocus = true;
}

function focusFirstField() {
    if (!anyFieldReceivedFocus) {
        // Do jQuery focus stuff
    }
}


<input type="text" onfocus="fieldReceivedFocus()" name="one">
<input type="text" onfocus="fieldReceivedFocus()" name="two">
