Use JavaScript to place cursor at end of text in text input element

Question

What is the best way (and I presume simplest way) to place the cursor at the end of the text in a input text element via JavaScript - after focus has been set to the element

Answer 1

Super easy (you may have to focus on the input element)

inputEl = getElementById('inputId');
var temp = inputEl.value;
inputEl.value = '';
inputEl.value = temp;
