Answer 2

The prototype activate () function focuses and selects the entire contents of the form elements.

In jQuery, this behavior can be replicated by three functions:

 // Focus $('my_element_id').focus(); // Focus and select the content. $('my_element_id').focus().select(); // Focus and select the content without problems in Google chrome $('my_element_id').focus().select().mouseup(function(event){ event.preventDefault(); }); 

Answer 3

 $('my_element_id').focus(); 

Answer 4

The jQuerys focus() method does not select text in the input field. Add select() instead:

 $('my_element_id').focus().select();
