استخدام العلامات

المطوّرون في المنطقة الاقتصادية الأوروبية

أنشئ علامات لنقاط طريق المسار من خلال استدعاء createWaypointAdvancedMarkers(). تنشئ createWaypointAdvancedMarkers() تلقائيًا علامات للمسار تحمل التصنيفات "أ" و"ب" و"ج" وما إلى ذلك لكل نقطة طريق. يمكنك تخصيص العلامات بشكل أكبر من خلال تمرير الخيارات لتغيير نمط العلامة استنادًا إلى فهرس العلامة أو خصائص RouteLeg المقابلة.

إضافة علامات تلقائية

لإضافة علامات باستخدام النمط التلقائي، استدعِ الدالة createWaypointAdvancedMarkers() مع تمرير خيار علامة لتحديد الخريطة الحالية، كما هو موضّح في مقتطف الرمز التالي.

// Create markers using default style.
const markers = await result.routes[0].createWaypointAdvancedMarkers({ map: innerMap });

ملاحظة مهمة: يجب طلب الحقل legs في ComputeRoutesRequest.fields لكي يتم تضمين نقاط المرور الوسيطة.

إضافة علامات بأسلوب مخصّص

لإضافة علامات باستخدام نمط مخصّص، استخدِم الدالة createWaypointAdvancedMarkers() مع تمرير خيارات العلامات التي تتضمّن خصائص النمط المخصّص. عند تطبيق أنماط مثل هذه، يتم تنسيق جميع العلامات بالطريقة نفسها. يوضّح مقتطف الرمز البرمجي التالي كيفية إنشاء علامات باستخدام نمط مخصّص.

// Create markers with a custom style.
const markerOptions = {
  map: innerMap,
  content: new PinElement({
    scale: 1.5,
    background: '#8C0DD1',
    borderColor: '#6D0AA5',
    glyphColor: '#6D0AA5',
  }).element
}

const markers = await result.routes[0].createWaypointAdvancedMarkers(markerOptions);

تطبيق نمط مخصّص على علامات فردية

لتطبيق نمط مخصّص على علامات فردية، مرِّر دالة إلى createWaypointAdvancedMarkers() لضبط خيارات نمط العلامة استنادًا إلى فهرس العلامة أو خصائص RouteLeg. يعرض مقتطف الرمز التالي دالة لإنشاء علامات وتنسيقها استنادًا إلى فهرس العلامة:

TypeScript

// Alter style based on marker index.
function markerOptionsMaker(
  defaultOptions: google.maps.marker.AdvancedMarkerElementOptions,
  //@ts-ignore
  waypointMarkerDetails: google.maps.routes.WaypointMarkerDetails
) {
  const { index, totalMarkers, leg } = waypointMarkerDetails;

  // Style the origin waypoint.
  if (index === 0) {
    return {
      ...defaultOptions,
      map: innerMap,
      content: new PinElement({
        glyphText: (index + 1).toString(),
        glyphColor: 'white',
        background: 'green',
        borderColor: 'green',
      }).element
    }
  }

  // Style all intermediate waypoints.
  if (!(index === 0 || index === totalMarkers - 1)) {
    return {
      ...defaultOptions,
      map: innerMap,
      content: new PinElement({
        glyphText: (index + 1).toString(),
        glyphColor: 'white',
        background: 'blue',
        borderColor: 'blue',

        borderColor: 'red',
      }).element
    }
  }

  return { ...defaultOptions, map: innerMap };
}

const markers = await result.routes[0].createWaypointAdvancedMarkers(markerOptionsMaker);index.ts

            map: innerMap,
            content: new PinElement({
                glyphText: (index + 1).toString(),

    if (!(index === 0 || index === totalMarkers - 1)) {
