全部代码，单点定位，轨迹点回放，视野切换全部实现，可就是轨迹画不出来，帮看下到底是哪边的问题

海绵宝宝，这个代码看着确实解决不了问题，我用的是JSP,也没法测试，要不你一点点测试代码，一处处alert，看这个画线的代码执行到哪步，是画了，还是画了又被清除掉了，另外我把我画线的函数给你贴出来，看对你有帮助没



function locatePathToMap(jsonObj){

  //参数为json格式:{mapxy,id,onmouseover,onclick,width,opacity,type,color,flashcolor}

  //type:solid,dash,dot,dashdot

  //flashcolor:闪烁颜色

  var arr_xys=jsonObj.mapxy.split(";"); //x1,y1;x2,y2;x3,y3

  var mobjid=jsonObj.id; //唯一关键字

  if (mobjid==null) mobjid="lineid";

  removeLocatorInMap(mobjid);

  var line = new esri.geometry.Polyline(); //map.spatialReference

  var points = [];

  for(var i=0;i<arr_xys.length;i++){

    mapxy=arr_xys[i].split(",");

    if (mapxy.length>1){

       points[i]=new esri.geometry.Point(mapxy[0],mapxy[1]);

    }

  }

  arr_xys=[];

  line.addPath(points);

  var sym = new esri.symbol.SimpleLineSymbol().setWidth(jsonObj.width);

  if (jsonObj.type=="dash"){

     sym.setStyle(esri.symbol.SimpleLineSymbol.STYLE_DASH);

  }else if (jsonObj.type=="dot"){

     sym.setStyle(esri.symbol.SimpleLineSymbol.STYLE_DOT);

  }else if (jsonObj.type=="dashdot"){

     sym.setStyle(esri.symbol.SimpleLineSymbol.STYLE_DASHDOT);

  }else{

     sym.setStyle(esri.symbol.SimpleLineSymbol.STYLE_SOLID);

  }

  sym.setColor(new dojo.Color(jsonObj.color));

  var graphic1 = new esri.Graphic(line,sym);

  var infoTemplate = new esri.InfoTemplate();

  if (jsonObj.title) infoTemplate.setTitle(jsonObj.title); //标题

  if (jsonObj.onclick) infoTemplate.setContent(jsonObj.onclick);

  graphic1.setInfoTemplate(infoTemplate);

  graphic1.user_overtext = jsonObj.onmouseover;

  graphic1.user_id =mobjid;

  if (jsonObj.flashcolor && jsonObj.flashcolor!=""){

    graphic1.user_flashcolor=new dojo.Color(jsonObj.flashcolor);

    graphic1.user_color=new dojo.Color(jsonObj.color);

  }

以上是全部代码，就差轨迹绘制为实现
