获取当前元素父级，然后每个元素jQuery

Question

I want to get current element parent, then for each check the class here is my code:

 jQuery('input[name^="opt"]').click(function() { if ( jQuery(this).hasClass('current_option') && jQuery(this).is(':checked') ) { jQuery(this).prop('checked', false); jQuery(this).removeClass('current_option'); opConfig.reloadPrice(); } else { var parents=jQuery(this).parent().parent(); jQuery(parents +'li > input').each(function() { alert("445"); }); jQuery(this).addClass('current_option'); } }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <ul> <li><input type="radio" value="1" name="opt[1]" /><li> <li><input type="radio" value="1" name="opt[1]" /><li> <li><input type="radio" value="1" name="opt[1]" /><li> <li><input type="radio" value="1" name="opt[1]" /><li> </ul> <ul> <li><input type="radio" value="1" name="opt[2]" /><li> <li><input type="radio" value="1" name="opt[2]" /><li> <li><input type="radio" value="1" name="opt[2]" /><li> <li><input type="radio" value="1" name="opt[2]" /><li> </ul> <ul> <li><input type="radio" value="1" name="opt[3]" /><li> <li><input type="radio" value="1" name="opt[3]" /><li> <li><input type="radio" value="1" name="opt[3]" /><li> <li><input type="radio" value="1" name="opt[3]" /><li> </ul> 

This part of code is not working. I have to remove the class for current parent other elements.

var parents=jQuery(this).parent().parent();
jQuery(parents +'li > input').each(function() {
  alert("445");
});

Answer 1

can you explain why you used this part of snippet ?

var parents=jQuery(this).parent().parent();
jQuery(parents +'li > input').each(function() {
  alert("445");
});

If you explain little-bit then some one maybe give the right idea to best way to do it. and one more thing what really you want to do with your full of code ?

Anyway you can't get li > input by parents variable that you store by using parent() function.

why don't you try find() to this for you ? like :

$(parents).find('input').each(function() {
  alert("445");
});
