How to export data from javascript to csv file

for (var i = 0; i < origins.length; i++) {
var results = response.rows[i].elements;
addMarker(origins[i], false);

addMarker(destinations[i], true);
outputDiv.innerHTML += origins[i] + ' to ' + destinations[i]
+ ': ' + results[i].distance.text + ' in '
+ results[i].duration.text + '<br>';

}

Do you have any idea how to implement something of that on my code?

Thanks

Hi nat06,

        }
        else if (navigator.msSaveBlob) { // IE 10+

        else {
            // it needs to implement server side export
            link.setAttribute("href", "http://www.example.com/export");
        }
        link.innerHTML = "Export to CSV";
        document.body.appendChild(link);

Hi Kevin,

I tried your example and here is what I have for the code:

 function callback(response, status) {
            if (status != google.maps.DistanceMatrixStatus.OK) {
                alert('Error was: ' + status);
            } else {
                var origins = response.originAddresses;
                var destinations = response.destinationAddresses;
                var outputDiv = document.getElementById('outputDiv');
                outputDiv.innerHTML = '';
                deleteOverlays();

                for (var i = 0; i < origins.length; i++) {
                   var results = response.rows[i].elements;
                    addMarker(origins[i], false);                    
                                        addMarker(destinations[i], true); 
                        outputDiv.innerHTML += origins[i] + ' to ' + destinations[i] 
                            + ': ' + results[i].distance.text + ' in '  
                            + results[i].duration.text + '<br>'; 

//I use the data that I write on the web site (in  outputDiv.innerHTML) to form csv file

                      //  csvData.push = ('"origins[i]", "destinations[i]", "results[i].distance.text", "results[i].duration.text"');                       
                 
                }
                var data = outputDiv.innerHTML;
                csvData.push = ('"origins", "destinations", "results.distance.text", "results.duration.text"');
                data.forEach(function (item, index, array) {
                    csvData.push('"' + item.origins + '","' + item.destinations + '","' + item.results.distance.text + '","' + results.duration.text + '"');
                });


            }
                   }

..
...
  google.maps.event.addDomListener(window, 'load', initialize);
        setInterval(function () { initialize(); calculateDistances(); exportCSV(); }, 20000);

            var buffer = csvData.join("\n");
            var uri = "data:text/csv;charset=utf8," + encodeURIComponent(buffer);
            var fileName = "data.csv";

            var link = document.createElement("a");
            if (link.download !== undefined) { 
              
                link.setAttribute("href", uri);
                link.setAttribute("download", fileName);
            }
            else if (navigator.msSaveBlob) { 
                link.addEventListener("click", function (event) {
                    var blob = new Blob([buffer], {
                        "type": "text/csv;charset=utf-8;"
                    });
                    navigator.msSaveBlob(blob, fileName);
                }, false);
            }
            else {
              
                link.setAttribute("href", "http://www.example.com/export");
            }
            link.innerHTML = "Export to CSV";
            document.body.appendChild(link);

but again the csv file remains empty

Hi nat06,

For your problem ,i suggest that you set a breakpoint on your javascript code check if your csvData has been filled with data.

And your problem is related with google map api,i recommend that you can post your question to their forum:

https://developers.google.com/maps/support/

Thanks Kevin, but when putting breakpoint on

csvData.push = ('"origins", "destinations", "results.distance.text", "results.duration.text"');

I get a message:

The breakpoint will not currently be hit. No executable code of the debugger's target code type is associated to this line.

msSaveBlob only works on IE. There are parts of html5 that do this

http://www.html5rocks.com/en/tutorials/file/filesystem/

but I don't think they are widely supported yet either. By far the best thing to do at the moment is submit the data to a webpage, have it create the file in-memory and stream it top the client for the browser to save. That is at least guaranteed to work on all browsers.

I'm afraid I no longer use this forum due to the new point allocation system.
