    copied!<p>Here is an analogy of my problem(a selector which has this selector together with a class selector):</p> <p>Let say that I selects all yellow(classes) div elements in a arbitrary HTML document. And I want each to check if the attribute is yes = 1. If the attribute 'yes' equals '1', then I want the child with class 'blue' have the attribute 'no' equals '1';</p> <pre><code>$('div .yellow').each(function(){ if($(this).attr('yes') == 1){ $(this '.blue:first-child').attr('no', 1);//This line needs to be fixed } }); </code></pre> <p>I know that the line <code>this.getElementsByClassName('blue')[0]</code> fixes this problem. But in my real problem (not this analogy) I want to use addClass and removeClass which only functions with jQuery objects. It is to cumbersome to use other functions than addClass and removeClass.</p> <p>UPDATE:</p> <p>Here is a code snippet from my real problem. I got some problem with "this" in javascript.</p> <p>I want a invited button to have the className visible when I click on it. The button lies within a div element with className 'box'. I know that there are problem with 'this' on the code snippet. But I want the button and not the box to change to visible</p> <pre><code>$('.Box').each(function(){ if($(this).attr('hasButton') != 1){ var invite = document.createElement('div'); invite.className = 'invite invisible'; invite.innerHTML = 'invite'; $(this).attr('hasButton', 1); this.appendChild(invite); invite.addEventListener('mouseover', function(event){ $('.invite', this).removeClass('invisible');//this line is not functioning $('.invite', this).addClass('visible');//neither this }, false); } }); </code></pre> <p>Ok solved it. I passed an element as attribute instead of classSelector.</p> <pre><code>$(invite).removeClass('invisible'); $(invite).addClass('visible'); </code></pre>
