मार्कर का इस्तेमाल करना

यूरोपियन इकनॉमिक एरिया (ईईए) के डेवलपर

createWaypointAdvancedMarkers() को कॉल करके, रास्ते के वेपॉइंट के लिए मार्कर बनाएं. डिफ़ॉल्ट रूप से, createWaypointAdvancedMarkers() हर वेपॉइंट के लिए, 'A', 'B', 'C' वगैरह लेबल वाले रूट के मार्कर बनाता है. मार्कर इंडेक्स या उससे जुड़े RouteLeg की प्रॉपर्टी के आधार पर, मार्कर के स्टाइल में बदलाव करने के लिए विकल्प पास करके, मार्कर को और भी ज़्यादा पसंद के मुताबिक बनाया जा सकता है.

डिफ़ॉल्ट मार्कर जोड़ना

डिफ़ॉल्ट स्टाइल का इस्तेमाल करके मार्कर जोड़ने के लिए, createWaypointAdvancedMarkers() को कॉल करें. साथ ही, मार्कर के विकल्प को पास करके मौजूदा मैप की जानकारी दें. ऐसा यहां दिए गए कोड स्निपेट में दिखाया गया है.

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

अहम जानकारी: इंटरमीडिएट वेपॉइंट शामिल करने के लिए, ComputeRoutesRequest.fields में legs फ़ील्ड का अनुरोध करना ज़रूरी है.

कस्टम स्टाइल वाले मार्कर जोड़ना

कस्टम स्टाइल का इस्तेमाल करके मार्कर जोड़ने के लिए, createWaypointAdvancedMarkers() कॉल करें. इसमें कस्टम स्टाइल प्रॉपर्टी शामिल करने वाले मार्कर विकल्प पास करें. इस तरह की स्टाइल लागू करने पर, सभी मार्कर एक ही स्टाइल में दिखते हैं. यहां दिए गए कोड स्निपेट में, कस्टम स्टाइल वाले मार्कर बनाने का तरीका बताया गया है.

// 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);

अलग-अलग मार्कर पर कस्टम स्टाइल लागू करना

अलग-अलग मार्कर पर कस्टम स्टाइल लागू करने के लिए, createWaypointAdvancedMarkers() को एक फ़ंक्शन पास करें. इससे मार्कर इंडेक्स या RouteLeg प्रॉपर्टी के आधार पर, मार्कर स्टाइल के विकल्प सेट किए जा सकते हैं. यहां दिए गए कोड स्निपेट में, मार्कर बनाने और मार्कर इंडेक्स के आधार पर उन्हें स्टाइल करने का फ़ंक्शन दिखाया गया है:
