如何将jQuery函数值传递给变量？

Question

I have this variable:

var tt_topiclist_fontsize = '{TT_topiclist_fontsize}';

and this small function:

$('input#TT_topiclist_fontsize.type-form').on('keyup', both);

function both(){
  window.opener.$('#header-site-description h1').css('fontSize', this.value + 'px');
}

So when I in input type in desired font size (some number), how can I pass that value to above variable ?

Thank you

var tt_topicList_fontsize ;
$('input#TT_topiclist_fontsize.type-form').on('keyup', function both(){
window.opener.$('#header-site-description h1').css('font-size', this.value + 'px');
tt_topicList_fontsize = this.value;
});
