title: jQuery - how can I find if an id has a specific string?
body: <p>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.</p>
  
  <p>if(myLastTdId Contains "blablabla"){ do something }</p>
  
  <p>Thanks!!!</p>
