我已創建使用下面的OpenLayers一個線串： -的OpenLayers，JavaScript的
$.each(coords, function(a){
console.log("entered coords:"+coords[a][0]+"//"+coords[a][1]);
webcentre.lat = coords[a][0];
webcentre.lon = coords[a][1];
mapref.panTo(webcentre);
var c = new openlayer.LonLat(coords[a][1], coords[a][0]),
e = new openlayer.Size(40, 70),
f = new openlayer.Pixel(-(e.w/2), -e.h + e.h/4),
g = new openlayer.Marker(c, new openlayer.Icon(l_wb1(coords[a][2]), e, f));
var startPt=new openlayer.Geometry.Point(coords[a][1], coords[a][0]);
if(a<(coords.length-1)){
//alert("a is less than coords length:::" +a);
endPt=new openlayer.Geometry.Point(coords[a+1][1],coords[a+1][0]);
}else {
//alert("a is greater than coords length");
endPt=new openlayer.Geometry.Point(coords[a][1],coords[a][0]);
}
console.log("startPt:"+startPt+"endPt:"+endPt);
line=new openlayer.Geometry.LineString([startPt, endPt]);
style={strokeColor : "red",
fillColor : "black",
pointRadius : 15,
fillOpacity : 0.5,
strokeWidth: 2,
lineSymbol:"farrow",
lineSymbolRadius:7,
lineSymbolReverse:0,
lineSymbolRepeat:0,
lineSymbolOffset:0,
lineSymbolStrokeWidth:2,
lineSymbolStrokeColor:"green",
lineSymbolFillColor:"green"};
fea=new openlayer.Feature.Vector(line, {}, style);
w = new openlayer.Layer.Vector(
"Trace Layer", {
styleMap: F
});
w.addFeatures([fea]);
mapref.addLayer(w);
var dd1=[];
dd1.push(coords[a][1]);
dd1.push(coords[a][0]);
dd.push(dd1);
return s.addMarker(g), g
});
現在，當我取消對清除按鈕的點擊功能，標記刪除，但不是線串。我試過使用removeFeatures（），destroy（），removeLayer（）。我試過使用removeFeatures（），destroy（），removeLayer（）方法來實現這個功能。但沒有任何工作。
請幫忙。
