Create a class in css name it  buttoncontact  add the class attribute to your buttons  function ClickedRow           document  on  click     buttoncontact   function              var row     this  parents  tr   attr  id            var rowtext     this  closest  tr   text            alert row

You can use  closest   to get up to the current  lt tr gt  parent  like this      input type button     click function        var bid   this id     button ID     var trid     this  closest  tr   attr  id       table row ID

First  your jQuery will not work at all unless you enclose all your trs and tds in a table    lt table gt       lt tr gt     lt  tr gt           lt  table gt    Second  your code gets the id of the first tr of the page  since you select all the trs of the page and get the id of the first one   attr   returns the attribute of the first element in the set of elements it is used on   Your current code        input type button     click function        bid    this id       button ID     trid      tr   attr  id       ID of the the first TR on the page                                     tr   selects all trs in the DOM         trid is always TEST1  jsFiddle     Instead of selecting all trs on the page with    tr    you want to select the first ancestor of the clicked upon input that is a tr  Use  closest   for this in the form   this  closest  tr     You can reference the clicked on element as this  make a jQuery object out of it with the form   this   so you have access to all the jQuery methods on it   What your code should look like        On DOM ready      function               input type button     click function                var bid  trid     Declare variables  If you don t use var                              you will bind bid and trid                              to the window  since you make them global variables             bid    this id       button ID             trid     this  closest  tr   attr  id       table row ID                  jsFiddle example

Your code would be more like so      tr input type button    click function        id     this  closest  tr   attr  id
