This is the easy way to do it. If you're going backwards, just add
<code>$("#Prefix").val($("#Prefix").val());</code> 
after you set the focus

This is the more proper (cleaner) way:

<pre><code>function SetCaretAtEnd(elem) {
 var elemLen = elem.value.length;
 // For IE Only
 if (document.selection) {
 // Set focus
 elem.focus();
 // Use IE Ranges
 var oSel = document.selection.createRange();
 // Reset position to 0 &amp; then set at end
 oSel.moveStart('character', -elemLen);
 oSel.moveStart('character', elemLen);
 oSel.moveEnd('character', 0);
 oSel.select();
 }
 else if (elem.selectionStart || elem.selectionStart == '0') {
 // Firefox/Chrome
 elem.selectionStart = elemLen;
 elem.selectionEnd = elemLen;
 elem.focus();
 } // if
 } // SetCaretAtEnd()
</code></pre>

I have turned it into a jQuery plugin for future use for anyone that needs it

 $.fn.setCursorToTextEnd = function() {
 var $initialVal = this.val();
 this.val($initialVal);

Chris Coyier has a mini jQuery plugin for this which works perfectly well: <a href="http://css-tricks.com/snippets/jquery/move-cursor-to-end-of-textarea-or-input/" rel="nofollow noreferrer">http://css-tricks.com/snippets/jquery/move-cursor-to-end-of-textarea-or-input/</a>

It uses setSelectionRange if supported, else has a solid fallback.

<pre><code>jQuery.fn.putCursorAtEnd = function() {
 return this.each(function() {
 $(this).focus()
 // If this function exists...
 if (this.setSelectionRange) {
 // ... then use it (Doesn't work in IE)
 // Double the length because Opera is inconsistent about whether a carriage return is one character or two. Sigh.
 var len = $(this).val().length * 2;
 this.setSelectionRange(len, len);
 } else {
 // ... otherwise replace the contents with itself
 // (Doesn't work in Google Chrome)
 $(this).val($(this).val());
 }
 // Scroll to the bottom, in case we're in a tall textarea
 // (Necessary for Firefox and Google Chrome)
 this.scrollTop = 999999;
 });
};
</code></pre>

Then you can just do:

<pre><code>input.putCursorAtEnd();
</code></pre>

I have 3 text boxes for a phone number. As the user types, it automatically moves from one textbox to the next. When the user presses backspace, I can move focus to the previous text box. The problem is that in IE, focus is set to the beginning of the text box. Here's my code, which works fine in chrome.

<pre><code>$('#AreaCode').live('keyup', function (event) {
 if ($(this).val().length == $(this).attr("maxlength"))
 $('#Prefix').focus();
});

$('#Prefix').live('keyup', function (event) {
 if (event.keyCode == 8 &amp;&amp; $(this).val().length == 0)
 $('#AreaCode').focus();

 if ($(this).val().length == $(this).attr("maxlength"))
 $('#Number').focus();
});

$('#Number').live('keyup', function (event) {
 if (event.keyCode == 8 &amp;&amp; $(this).val().length == 0)
 $('#Prefix').focus();
});
</code></pre>

How do I make the focus set at the end of the contents when going backwards?
