Hey Guys,

This is my javascript code:

C#

function calcRouteA() {

      var start = document.getElementById('DropDownList1').value;
      var end = document.getElementById('DropDownList2').value;
      var request = {
          origin: start,
          destination: end,
          provideRouteAlternatives: true,
          unitSystem: google.maps.UnitSystem.METRIC,
          travelMode: google.maps.DirectionsTravelMode.TRANSIT,
          transitOptions: {
          departureTime: new Date(1362568344000)
          }



      };
      directionsService.route(request, function (response, status) {
          if (status == google.maps.DirectionsStatus.OK) {
              directionsDisplay.setDirections(response);
          }
                  });

              }

is it possible that I can write this function in the aspx.cs page?
Please reply asap.

Why do you want it in C#? Javascript executes on the client and C# executes on the server. You'll have to read the Google api documentation to find out though.

I want to add a switch case which will take input from asp radio button list which will take this javascript function and give output depending on the different departure time mentioned.
Currently the timestamp mentioned is for morning 9:00 am.

You can still do that in JS.

Abhinav_007 21-Mar-13 8:11am

can you please show that with an example.
It would be really helpful.

Which part are you stuck on? You just need to get a value from a radio button list?

Abhinav_007 21-Mar-13 8:21am

Yes sir. In the first place i'm not able to call this function using a an asp radio button in a switch case. Meaning I simply don't know how to do that.

"i'm not able to call this function using a an asp radio button in a switch case. " What does this mean? Are you wanting to call the function when the radio button is clicked or are you saying you want to check which radio button is selected in the function?

If you would use jquery it will make this much easier. For example, to get the value of a radiobutton list in jquery you do $('#RadioButtonList1 input:checked').val()

Sir, actually i'll be inputting source, destination and the timezone(asp radio button) and as soon as i click get direction button(asp button), It shoud show me the output.

Hi,

declare string variable. and make that function as string and assign that string value in that variable.

C#

string jsFn = "function calcRouteA() {var start = document.getElementById('DropDownList1').value; var end = document.getElementById('DropDownList2').value;"
      + "var request = {          origin: start,          destination: end,          provideRouteAlternatives: true,          unitSystem: google.maps.UnitSystem.METRIC,"
          + "travelMode: google.maps.DirectionsTravelMode.TRANSIT,          transitOptions: {          departureTime: new Date(1362568344000)          }  };"
            + "directionsService.route(request, function (response, status) {          if (status == google.maps.DirectionsStatus.OK) {              directionsDisplay.setDirections(response);          }"
            + "                  });}";

call that function like below...

ddl1.Attributes.Add("onselect", jsFn);
