Programmatically selecting text in an input field on iOS devices (mobile Safari)

How do you programmatically select the text of an input field on iOS devices, e.g. iPhone, iPad running mobile Safari? Normally it is sufficient to call the .select() function on the <input ... /> element, but this does not work on those devices. The cursor is simply left at the end of the existing entry with no selection made.

モバイルsafariだとinputのtextにフォーカス時に全体が選択状態にならないので、setSelectionRangeを使うとよい。
