I have issue with setting value of select input by jquery -

here code saved on jsfiddle

i want change jquery value of item doesn't change.. when try console same code ok.. please help.. here returning -1 setting by

 .val(value).change() 

.change() listening event listens change value of something.

to change value of form element need:

$('input').val('changed value of textbox'); 

if trying change value inside of html tags:

$('div').html('changed html inside div') 

also not set properties of html element using .attr()

//change line .attr("selected", "selected");  //into line select dropdown item .prop('selected', true);  //or unselect .prop('selected', false); 

hopefully helps!
