How to make use of click event (google pie chart) in a second script

[Olaf]

Hi all,

I use the Google pie chart. I generate the script from a server java class and let it show in a browser. I have a different java script that contains a function. My question is: How can I call this function from my generated Google pie chart script:

 +       "var options = {'title':'Content Type', "
                 +                      "'width':800, "
                 +                      "'height':600,"
                 +                        "'chartArea.left':'50%',colors:['red','#706464','#E9DCDC','#3D0808','black']}; "
                 +       "var chart = new google.visualization.PieChart(document.getElementById('Formular')); "
                 +       "function selectHandler() { "
                 +         "var selectedItem = chart.getSelection()[0]; "
                 +         "if (selectedItem) { "
                 +           "var auswahl = data.getValue(selectedItem.row, 0); "
                 +           "alert('The user selected ' + auswahl); " <---------------------------------------------------------------------------Works perfect!
                 //+             "suSo.push('{\"Funktion\":\"antworten\",\"Text\":\"type\",\"Wert\":auswahl}');" <-------------------Causes the pie chart not to show up when enabled?
                 +         "} "
                 +       "} "
                 +       "google.visualization.events.addListener(chart, 'select', selectHandler); "   
                 +       "chart.draw(data, options); "
                 +     "} "
                 +   "</script> ";

I only started to use the GPC. So this might be a newbee question.

Thank you in advance

Open the page in Chrome and view the developer's console (ctrl+shift+j to open).  What error message(s) do you see?

Also, if you need help debugging, posting a link to the page or a copy of the code as seen by a browser (after it has been rendered by the server, open the page and view the source to get it) is most helpful to us.

Hi, thank you for your help. I managed to workaround the problem by integrating the chart api functions in my main script. BW Olaf
