禁止拖拽“来源” Google Maps v3 Directions API中的标记

问题描述

我试图使用Google Maps Directions API的v3显示地图。我无法弄清楚如何在目标上启用标记拖动功能，并禁用拖动原点标记。

我明白这可以在这里设置：

$ b $然而，如何访问正确的标记以禁用拖动？通过zIndex？我也试过

response.routes [0] .legs [0] .start_location
没有效果。任何指针？

解决方案

想象一下，Ya'll：

链接：

编辑（改为粗体）：

//用于禁用拖动origen :)（第78行）

startLocation.marker = createMarker（legs [i] .start_location，start，legs [i] .start_address，green， false ）;

//用于启用拖动：（目的地）（第108行）

endLocation.marker = createMarker（endLocation.latlng，end ，endLocation.address，red， true ）;

//更新createMarker函数（第175行）

createMarker（latlng，lable，html，color， drag ）

//更新google.maps.Marker（第178行）

var marker = new google.maps.Marker（{

position：l atlng，

可拖动：拖动，

地图：地图，

阴影：iconShadow，

图标：getMarkerImage（color），

shape：iconShape，

title：label，

zIndex：Math.round（latlng.lat（）* - 100000） << 5

}）;

* 注意：您还需要标记，找到和 - 并放置在一个名为mapIcons /的代码的相同目录中的文件夹*

I'm attempting to display a map using v3 of Google Maps Directions API. I can't figure out how to enable dragging on the marker for the "destination" and disable the dragging for the "origin" marker.

I understand this can be set here:http://code.google.com/apis/maps/documentation/javascript/reference.html#MarkerOptions

however, how to access the correct marker to disable dragging? by zIndex? I've also tried
response.routes[ 0 ].legs[ 0 ].start_location with no effect. Any pointers?

解决方案

Figured It Out, Ya'll:

Link: Customer Marker Example, with some minor changes show below:

Edit (change in bold):

// for disabled dragging (origen:) (line 78)
startLocation.marker = createMarker(legs[i].start_location,"start",legs[i].start_address,"green", false);

// for enabled dragging: (destination) (line 108)
endLocation.marker = createMarker(endLocation.latlng,"end",endLocation.address,"red", true);

// update createMarker function (line 175)
createMarker(latlng, lable, html, color, drag)

// update google.maps.Marker (line 178)
var marker = new google.maps.Marker({
position: latlng,
draggable: drag,
map: map,
shadow: iconShadow,
icon: getMarkerImage(color),
shape: iconShape,
title: label,
zIndex: Math.round(latlng.lat()*-100000)<<5
});

*Note: you will also need the markers, found here and here - and place in a folder in the same dir as code called "mapIcons/" *
