Hi I tried to change it by accessing its url.

point_url = cloneGra.symbol.__accessor__.store._values.url;

and tried to change the symbol point_url in l while saving that marker, but it do not change.????

Do anyone know how to change symbol of individual marker

1 when we click on that marker,

2 define a marker type in textbox save it and

3 change its symbol.

var pointurl = funurl(mtype);
point_url.url = pointurl;

console.log(point_url.url);

It return perfect url but do not chnge marker symbol instantly i have to zoom in or zoomout that map then the markers change???

Plus when i again change the same marker it do not chnage symbol

Thanks in advance, this is my code below

point_url = cloneGra.symbol.__accessor__.store._values;

                    //save marker button
           jQuery('#main').on('click','.savemarker',function(e){
              var points_arr=[];
              var markertype = jQuery(this).parents().find('.dropdownbtn').html();
              var comment = jQuery(this).parents().find('.write_comment').val();
              var tempoint = changedMarkerSymbol(markertype);//passing type of marker to this function
                point_url.url = tempoint;//tempoint contain new url
              points_arr={'x' : point_x_coordinate , 'y' : point_y_coordinate};
                 jQuery.ajax({
                                 //send ajax call to save data
                                    success: function(data){
                                      }
                                    });

Rajni,

The simple solution is to remove that graphic and re-add it with the new symbology.

Hi Robert Scheitlin, GISP‌

I am changing marker symbol url here

//This is tempgraphics function

markerGL.add(cloneGra);
   point_url = cloneGra.symbol.__accessor__.store._values;
            }//End If
           }//End addTempGraphics

//On button save click

point_url = cloneGra.symbol.__accessor__.store._values;

var tempoint = changedMarkerSymbol(markertype);//passing type of marker to this function and it return new symbol url
point_url.url = tempoint;//tempoint contain new url
