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

Simple. When editing or changing values, first put the focus then set value.

$("#catg_name").focus();
$("#catg_name").val(catg_name);
