Good day!

When working with a set there was an incomprehensible problem to me. I am required to wrap the whole set in one item. for example, you need to wrap all input type="radio" div element. I am writing the following:

jQuery code:

 $(function(){ var form = $('form').children(); form.each(function(n){ if($(this).is(':radio') $(':radio').wrapAll('<div class="radios"></div'); }); });

And, it seems, there should be happiness - all radio elements should turn around with a common div element. Annette! in the DOM see the following:

DOM :

 <div class="radios"> <div class="radios"> <input type="radio" name="choise" value="yes"/>Yes <input type="radio" name="choise" value="no"/>No </div> </div>

I can't figure out where the external div comes from. Tell me please!

Amendment!!! You cannot leave the loop bypass!))

    no wonder, since you execute .wrapAll() with each iteration of the .each() loop. I can offer this option:

     $(function(){ var form = $('form').children(); var flag = true; form.each(function(n){ if(!$(this).is(':radio'){ flag = false; return; } }); if(flag){ $(':radio', $('form')).wrapAll('<div class="radios"></div'); } });

      @Spectre , your answer is correct with a small amendment! This is really an entry problem. But you propose to leave the cycle, and this is not exactly what is needed. It is my fault, I did not clarify this important point in the question. Therefore, you have a plus, but I offer my solution:

      jQuery code

       $(function(){ var form = $('form').children(), radio_founded = false; $(form).each(function(n){ if($(this).is(':radio')&&!radio_founded) { radio_founded = true; $(':radio').wrapAll('<div class="radios"></div>); } }); });
      • exactly the task at hand is the key to the success of its implementation =) - Specter
      • =) that's right. Only now as a question to close =) - LeD4eG
      • there is a question to close the button, specify the reason and everything - Specter
      • it is different) moral dilemma so to speak)) ok, you have to be completely honest! I will accept your answer. and those who will then read it let them choose which answer is correct. - LeD4eG
