jQuery - how can I find if an id has a specific string?

Question

I have a table and I want to know if its last td its id contains a certain string. For example, if my last td has id "1234abc", I want to know if this id contains "34a". And I need to do that in a 'if' statement.

if(myLastTdId Contains "blablabla"){ do something }

Thanks!!!

Answer 1

You could use the "attributeContains" selector:

if($("#yourTable td:last-child[id*='34a']").length > 0) { 
   //Exists, do something...
} 

Answer 2

This is easily done with indexOf and last-child.

<table id='mytable'>
<tr>
  <td id='abc'></td>
  <td id='cde'></td>
</tr>
</table>

<script>
if($('#mytable td:last-child').attr('id').indexOf('d') != -1) {
   alert('found!');
}
</script>

Here it would alert 'found' because d appears in the string cde
