hiding parent when a span contains no content

I've been up and down the site and various questions related to this, I cannot find a resolution for this.

I'm try to hide my parent div "row" whenever my span "specvalue" contains no data

    <div class="container-fluid" id="itmSpecsTbl">
 <div class="row" id="row"><div class="col-xs-6" align="left"><b>Accuracy</b> </div><div class="col-xs-6" align="right"><span id="specvalue"><%=getAttribute('item','127559','custitem1','')%></span> </div></div>

</div>

The "getAttribute" is used to pull data of my items, when there's no data. it's blank - no spaces, nothing.

I've tried using :empty, :blank

#specvalue:empty #row, #specvalue:blank #row { display: none; }

This got me nowhere, same with jquery

$("#specvalue:empty").parent().hide();

Nothing has worked so far, I've even tried placing the script inside the <head> tag, and even below after the tech documents are called.

Do you think I need to be more specific with the CSS? I see it works on other examples, but not on this.

Solution

  • I've removed the duplicate id="row" and replaced id="specvalue" with class="specvalue". Then with some simple jquery I've hidden all rows with empty specvalue.

    Note: always keep in minde id's always have to be unique within the full html page!

    $('.specvalue').each(function(i, v) {
  if ($(this).html() === '') {
    $(this).closest('.row').hide();
  }
});
