javascript - Select all text on focus in numbers fields -



javascript - Select all text on focus in numbers fields -

i have aspx text box class num_input. should allow numbers , automatically add together comma separator:

$('.num_input').live("keyup", function () { $(this).numeric(); var num = $(this).val().replace(/(,)/g, ''); $(this).val(num.replace(/(\d)(?=(\d{3})+(?!\d))/g, "$1,")); });

we have new requirement select text when user navigates through others textbox using tab or placing cursor in text.

i tried utilize

$(this).select();

but didn't work!!

jquery's select function isn't @ dedicated selecting text.

if need that,

this.selectionstart = 0; this.selectionend = this.value.length;

you can define function letting select text of jquery element :

$.fn.selecttext = function(){ this.each(function(){ this.selectionstart = 0; this.selectionend = this.value.length; }); }

demonstration

javascript jquery
