zeeshanbhatti

i am drawing line using this code reference from

http://help.arcgis.com/en/webapi/javascript/arcgis/help/jsapi_start.htm

var myLine ={geometry:{"paths":[[[-91.40625,6.328125],[6.328125,19.3359375]]],
  "spatialReference":{"wkid":4326}},
  "symbol":{"color":[0,0,0,255],"width":1,"type":"esriSLS","style":"esriSLSSolid"}};
var gra= new esri.Graphic(myLine);
map.graphics.add(gra);

How can i delete the line if i am trying to draw in above mention way.
The samples for deleting graphics method is not clear if we are drawing using inputs parameters. Can some one help us through code.

i dont know of a delete function for objects in javascript, but you might try:

var gra= new esri.Graphic(myLine);
map.graphics.add(gra);

gra.hide(); // hide the graphic
gra=null;

setting it to null 'should' let the js engine know that the object is available for garbage collection, whether it gets collected or not.. who knows.
