rated 0 times [ 20] [ 5] / answers: 1 / hits: 27200 / 8 Years ago, fri, september 2, 2016, 12:00:00

I need to get the value of userid, data-attribute from a html table and put this value into a var, but I wanna to this action without click action.

  <table id=tblList>

    <tbody id=someTest>

      <tr data-userid=801992084067>

      <tr data-userid=451207954179>

      <tr data-userid=310896831399>

      <tr data-userid=863939754980>

      <tr data-userid=1123542226482>

    </tbody>

  </table>

I have tried to do this like that, but the rowId is undefined.

 var rowId = $(#someTest tr).last().attr([data-userid]);

only Remove [] :

 var rowId = $(#someTest tr).last().attr(data-userid);

Final code :

<html>

    <title>This is test</title>

    

    <head>

    </head>

    <body>

        <table id=tblList>

    <tbody id=someTest>

      <tr data-userid=801992084067>

      <tr data-userid=451207954179>

      <tr data-userid=310896831399>

      <tr data-userid=863939754980>

      <tr data-userid=1123542226482>

    </tbody>

  </table>

        

        <script src=https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js></script>

        <script>

            

$(document).ready(function(){

    

   var rowId = $(#someTest tr).last().attr(data-userid);

    alert(rowId);

       

})

        </script>

    </body>

</html>
