Background

I plan to select the whole text inside an input field if user focus on the field.

Enivronment

IE11 under Win 7 64 bits

FF31 under Win7 64 bits

Method

$(function(){
jQuery(document).on('focus',XXX) 
});

function XXX{
this.select();
}

Result

IE11: jQuery.on does NOT work. The text is not selected. But if I use addEventListener instead, it works well.

FF31: Both jQuery.on or addEventListener work
