Javascript if box checked


i have this form for adding videos. Now, there's a input field for "title" and i want that to disappear if you have pressed on the checkbox "tryout". How should i do that in JS.. i use jquery.


Assuming you have correct ids assigned for both fields something like this will work:

$('#tryout').click(function () { $('#title').toggle(!$(this).attr('checked')); });


you can just write inside document.ready function.

$("#chkboxId").clicked(function(){ if($(this).attr("checked")) $("#title").hide(); else $("#title").show(); });


<input type="checkbox" id="tryout" name="tryout" onclick="javascript:$('#tryout').hide();">Tryout</input>
