Checking the Value of the Second Child Element Using jQuery

I am struggling with a DIV structure that looks like this:

<div class="metafield_table">
   <div class="metafield"></div>
   <div class="metafield"></div>
   <div class="metafield"></div>
</div>

The number of metafield elements can vary, and I specifically need to determine if the Second Child exists.

How can I achieve this using jQuery?

This is what I attempted:

var secondChild = $('.metafield_table .metafield:nth-child(2)').val;
  if(!secondChild) {
    $('.metafield').css({'width': '100%'});
  }
  else {
    $('.metafield').css({'width': '50%'});
  }

Even when there's only one metafield, it always executes the else condition! Any ideas on how to fix this?

Answer №1

If you believe your selector is accurate, you can verify the presence of the element using the following method:

var secondChild = $('.metafield_table .speci_wrap:nth-child(2)');

if(secondChild[0]){
  // The element exists
}else{
  // The element does not exist
}

Answer №2

let totalNum = 0;

$('.metafield').each(function() {
  totalNum++;
});


if (totalNum > 1) {
  $('.speci_wrap').css({
    'width': '100%'
  });
} else {
  $('.speci_wrap').css({
    'width': '50%'
  });
}
