Question

<input type="text" id="textbox">
<input type="radio" id="radio1" name="on">
<input type="radio" id="radio2" name="off">

I need to display #textbox only if #radio1 is selected (first pageload). Or #radio2 is selected on first page load and the user clicks #radio2 the textbox should also show.

Any suggestions how to do this?

   $('#textbox').show();
});
