我正在使用Google Maps API v3,並試圖提供「顯示下一個路由」按鈕,用戶可以在其中循環所有可用路由。Google Maps API v3:routeIndex不工作?
我得到它顯示第一個路線,但是當我使用DirectionsRenderer類的routeIndex屬性時,它只返回第一個路線。
我做錯了什麼?代碼粘貼在下面。我一直使用的測試路線共有三條路線。如果我將routeIndex屬性設置爲1,它仍然顯示數組中的第一個路由(基本上,routeIndex [0])。
function showDirections() {
// show contact buttons
$(".contact-route-button").css({display:"block"});
// add 1 to count
count++;
// If this function has been run before, clear the directions
if(count > 1){
// Clear map
directionsDisplay.setMap(null);
//Clear Route List
document.getElementById('directions').innerHTML = "";
}
// Set map to render directions
directionsDisplay = new google.maps.DirectionsRenderer({
map: map,
/*preserveViewport: true,*/
draggable: true,
routeIndex: 1
});
// Remove hidden class form text explaning driving directions
$('#drive-text').fadeIn("fast").removeClass('hidden');
// Hide paragraph under directions form
$(".section.grids-two.maximum-780.clearfix .grid.grid-2").fadeOut("fast");
// SlideToggle panel about random fact
$(".random-fact").slideDown("fast").css({display:"block"});
// Set Panel that will display driving directions
directionsDisplay.setPanel(document.getElementById('directions'));
// Get address input text
var address = document.getElementById('dir-address').value;
// Create request to send to Google starting at the address provided
var request = {
origin: address,
destination: '531 E Market Street Indianapolis, IN 46204',
travelMode: google.maps.TravelMode.DRIVING,
unitSystem: google.maps.UnitSystem.STANDARD,
provideRouteAlternatives: true
};
// Send request and display on map and directions box
directionsService.route(request, function(response, status) {
if (status === google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
totalRoutes = countRoutes(response);
}
});
}
任何想法?我遵循的說明在谷歌地圖API文檔上,https://developers.google.com/maps/documentation/javascript/reference#DirectionsRendererOptions
在此先感謝!
我會嘗試。 謝謝! – dauble 2013-03-12 13:20:46
