Hello!
I'm running a web server with a PIC32MX microprocessor running on FreeRTOS. I'm using java scripting to refresh variable from server.
Now i should save these variables on a text file client side.
Please, can you help me?
Thank you!
MM

    I should save table data as CSV, XLS or PDF files
  • allanallan Posts: 63,534Questions: 1Answers: 10,475 Site admin
    TableTools allows you to do that, yes. It could be used to output a different format as well if you need, but those are the default built in ones.

    How you downloaded TableTools and set up sDom like that shown in the example: http://datatables.net/extras/tabletools/ ?

    Where exactly are you initialising the DataTable? I don't see it there.
  • pic32rtospic32rtos Posts: 12Questions: 0Answers: 0
    Maybe i should insert this code?:
    [code]
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">





    DataTables example

    @import "../../media/css/demo_page.css";
    @import "../../media/css/demo_table.css";




    $(document).ready(function() {
    var oTable = $('#example').dataTable( {
    "bProcessing": true,
    "sAjaxSource": "arrays.txt"
    } );
    } );





    DataTables AJAX source example


    Preamble
    Although DataTables is built from the principle of progressive enhancement, it is often useful to be able to

    construct a table from an AJAX source. This can be done in one of two ways - either using the aData initialisation parameter which

    takes an array of data, or using the sAjaxSource initialisation parameter which will have DataTables go to that source with an XHR call

    and load data from there. This example shows the latter method in action. DataTables expects an object with an array called "aaData" with the

    data source.

    First of all thanks to allan for the support.
    Now the question is...
    Is there anyway to automatic save on file the table?

    Thanks so much!

    Where are you setting the content of the table? I see you've got some of my demo content, but I presume you are overwriting that somehow?
  • pic32rtospic32rtos Posts: 12Questions: 0Answers: 0
    Hello!
    I'm using this ? to refresh the value passed from the server, but when I save the file I can't see the value displayed on screen, but only this "?".
  • pic32rtospic32rtos Posts: 12Questions: 0Answers: 0
    I refresh the variable content with this java script:
    [code]

    function aggiornaStato1(xmlData) {
    document.getElementById('adc10an0').innerHTML = getXMLValue(xmlData, 'adc10an0');
    }
    setTimeout("newAJAXCommand('testpanel.xml', aggiornaStato1, true)",100);
    //-->
