fnCellRender - Copied 0 rows to clipboard

wilsontc

I'm trying to use fnCellRendrer to preprocess cell data before exporting it. Everything works as expected when I don't extend the button, but when I try a simple proof of concept for extending a button, I get Copied 0 rows to clipboard.

Here is the relevant code:

    tableTools = new $.fn.dataTable.TableTools( msTable, {
      "sSwfPath": "/assets/dataTables/extras/swf/copy_csv_xls_pdf.swf"
      "aButtons": [
        {
          "sExtends": "copy",
          "fnCellRender": ( sValue, iColumn, nTr, iDataIndex ) ->
            msName = sValue
            if iColumn == 0
              msName = $(sValue).find('.ms-assoc-pnl')[0].innerHTML.trim()
              console.log msName
            return msName
        },
        "csv",
        "xls",
        "pdf",
        "print"
      ]
    } )

I found the issue. The last row in my table is actually a form that allows you to create a new row. As such it doesn't have the .ms-assoc-pnl class, so the find was coming up empty. Everything failed silently after that.

I just separated the find from the rest of that line and checked whether the length of the result was > 0 before going after the innerHTML.
