    Problem while dynamically passing params to javascript functions.

    Hi,

    I am using the following javascript method inside a js file.

    function createDivRow(la bel,text) {

    var formedTd = '<tr><td>' + label + '</td><td> <a href="#" onclick="javasc ript:eventHandl erFunction("'+t ext+'")">'+text +'</a></td></tr>';
    return formedTd;
    }

    But it's throwing syntax error.
    I have tried the following way also.

    function createDivRow(la bel,text) {

    var formedTd = '<tr><td>' + label + '</td><td> <a href="#" onclick="javasc ript:eventHandl erFunction('+te xt+')">'+text+' </a></td></tr>';
    return formedTd;
    }

    this version throwing ')' expected and also, the value of text which i am passing dynamically is undefined.

    I am not able to call the eventHandlerFun ction() by passing the dynamic value of the 'text' .

    I am using IE6. can any one help me....

      hi ...

      try this:

      [CODE=javascript]
      var formedTd = '<tr><td>'
      + label
      + '</td><td> <a href="#" onclick="javasc ript:eventHandl erFunction("'
      + text
      + '")">'
      + text
      + '</a></td></tr>';
      [/CODE]

      the problem should be your linebreak before 'onclick'

      kind regards ...

              ... when trying this in FF & IE it works for me ...

              [HTML]<body>
              <script>
              var label = 'test';
              var text = 'test1';

              var formedTd = '<tr><td>'
              + label
              + '</td><td> <a href="#" onclick="javasc ript:eventHandl erFunction("'
              + text
              + '")">'
              + text
              + '</a></td></tr>';

              alert(formedTd) ;
              </script>
              </body>
              [/HTML]

              please post your code that is not working ...

              kind regards ...

                  ahhhhhhhhhh ... got your problem ... you put the formedTd-string in an HTML-page and you want the function called ... ;) of course ...

                  you must escape the quotes and single quotes of course ... sorry that i forgot it ... use the following:

                  [CODE=javascript]
                  var formedTd = '<tr><td>'
                  + label
                  + '</td><td> <a href="#" onclick="javasc ript:eventHandl erFunction(\''
                  + text
                  + '\')">'
                  + text
                  + '</a></td></tr>';
                  [/CODE]

                  but note ... that assumes that text is a string passed to your eventHandlerFun ction ... otherwise you should delete the both escaped quotes

                  kind regards

                      yeah...,with the single quote escapes, it's working now...
                      Thanks a lot for your help.I tried different ways of calling that function with the dynamic value of 'text'.But nothing helped me. I am really thankful to you...:)
