There are two parts to your question.
1) How to focus an input on page load?
You can just add the autofocus attribute to the input.
<input id="myinputbox" type="text" autofocus>
However, this might not be supported in all browsers, so we can use javascript.
window.onload = function() {
var input = document.getElementById("myinputbox").focus();
}
2) How to place cursor at the end of the input text?
Here's a non-jQuery solution with some borrowed code from another SO answer .
function placeCursorAtEnd() {
if (this.setSelectionRange) {
// Double the length because Opera is inconsistent about
// whether a carriage return is one character or two.
var len = this.value.length * 2;
this.setSelectionRange(len, len);
} else {
// This might work for browsers without setSelectionRange support.
this.value = this.value;
}
if (this.nodeName === "TEXTAREA") {
// This will scroll a textarea to the bottom if needed
this.scrollTop = 999999;
}
};
window.onload = function() {
var input = document.getElementById("myinputbox");
if (obj.addEventListener) {
obj.addEventListener("focus", placeCursorAtEnd, false);
} else if (obj.attachEvent) {
obj.attachEvent('onfocus', placeCursorAtEnd);
}
input.focus();
}
Here's an example of how I would accomplish this with jQuery.
<input type="text" autofocus>
<script>
$(function() {
$("[autofocus]").on("focus", function() {
if (this.setSelectionRange) {
var len = this.value.length * 2;
this.setSelectionRange(len, len);
} else {
this.value = this.value;
}
this.scrollTop = 999999;
}).focus();
});
</script>

Just a heads up - you can now do this with HTML5 without JavaScript for browsers that support it:
<input type="text" autofocus>
You probably want to start with this and build onto it with JavaScript to provide a fallback for older browsers.

function focusOnMyInputBox(){
document.getElementById("myinputbox").focus();
}
<body onLoad="focusOnMyInputBox();">
<input type="text" size="25" id="myinputbox" class="input-text" name="input2" onfocus="this.value = this.value;" value = "initial text">

A portable way of doing this is using a custom function (to handle browser differences) like this one .
Then setup a handler for the onload at the end of your <body> tag, as jessegavin wrote:
window.onload = function() {
document.getElementById("myinputbox").focus();
}

Working fine...
window.onload = function() {
var input = document.getElementById("myinputbox").focus();
}

This is what works fine for me:
<form name="f" action="/search">
<input name="q" onfocus="fff=1" />
</form>
fff will be a global variable which name is absolutely irrelevant and which aim will be to stop the generic onload event to force focus in that input.
<body onload="if(!this.fff)document.f.q.focus();">
<!-- ... the rest of the page ... -->
</body>

If you can't add to the BODY tag for some reason, you can add this AFTER the Form:
<SCRIPT type="text/javascript">
document.yourFormName.yourFieldName.focus();
</SCRIPT>

Try:
Javascript Pure:
[elem][n].style.visibility='visible';
[elem][n].focus();
Jquery:
[elem].filter(':visible').focus();

Add this to the top of your js
var input = $('#myinputbox');
input.focus();
Or to html
<script>
var input = $('#myinputbox');
input.focus();
</script>
