This works

$('input[name=nickname]').css(...);

Now how can I write the same but with variable ?

string[1]='nickname';

Answer 1

Simply use string concatenation:

$('input[name=' + string[1] + ']').css(...);

Although technically it should be both $('input[name="nickname"]').css(...); and $('input[name="' + string[1] + '"]').css(...);

Answer 2

$('input[name=' + var_that_holds_the_name + ']').css(...);
