javascript - Basic Jquery - If Text exists in a TD then Make a DIV Visible -

i'm trying make div on page appear if word exists later on page? , i'd display if words in list of 10 appear on page? place want them inside of td class "sku nobr" after span class "td-title"

i'm total rookie @ this, got work h1 value code don't know how 4523 now??

thanks!!!!!

<script type="text/javascript">  $(document).ready(function(){   if ($(".sku nobr:contains('4523')").length) {     $("#thingtohide").removeattr("style").none();  }  });  </script>

  <div id="thingtohide" style="display: none;">cool text display</div>        <tr class="cart-item-row">        <td class="sku nobr">          <span class="td-title">sku:</span>          4523        </td>      </tr>

first, html not valid. you're missing <table></table> tags.

<div id="thingtohide" style="display: none;">cool text display</div> <table>     <tbody>         <tr class="cart-item-row">             <td class="sku nobr">                 <span class="td-title">sku:</span>4523             </td>         </tr>     </tbody> </table> 

second, selector wrong. replace .sku nobr:contains('4523') .sku:contains('4523')

$(document).ready(function(){     if ($(".sku:contains('4523')").length) {         $("#thingtohide").show();     } }); 

edit if looking number (which can include commas), have more creative. can use filter method. here's demo.

$(document).ready(function(){     // find td class 'sku' containing numbers     var $sku = $("td.sku").filter(function () {         // assuming number 4523,8563,9997,7757         // text = $.trim($(this).text());     => sku:4523,8563,9997,7757         // text = text.replace(/sku:|,/g, ''); => 4523856399977757         var text = $.trim($(this).text().replace(/sku:|,/g, ''));         // check number         return text && !isnan(text);     });     // check if there matches     if ($sku.length) {         $("#thingtohide").show();     } });
