如何更改 Gmap 标记颜色？

发布于 2024-08-11 15:49:36 字数 411 浏览 4 评论 0原文

我有一个带有不同点的自定义谷歌地图：

Markers[0] = new Array(new GMarker(new GLatLng(45.0, 9.0)), "Location1", "<strong>Address Line</strong><br/>Some information");
Markers[1] = new Array(new GMarker(new GLatLng(45.0, 12.0)), "Location2", "<strong>Address Line</strong><br/>Some information");

等等。

我只是想将标记的颜色从默认的红色更改为红色。即第二个蓝色。

如何做到这一点？

原文

I've a custom google map with different points:

Markers[0] = new Array(new GMarker(new GLatLng(45.0, 9.0)), "Location1", "<strong>Address Line</strong><br/>Some information");
Markers[1] = new Array(new GMarker(new GLatLng(45.0, 12.0)), "Location2", "<strong>Address Line</strong><br/>Some information");

etc.

Simply I want to change the color of the markers from the default red. I.E. the 2nd blue.

How to do this?

这是一个简单的代码，允许谷歌地图使用多种颜色标记，

<?php
$con = mysql_connect("localhost","root","");
$Db=mysql_select_db("map",$con);
$select_det=mysql_query("select * from record");

// some code

您必须将标记图像从名为“pointer_image”的文件夹中放入，

更改代码

您可以通过编辑这部分代码来

<script type="text/javascript">
var greenIcon = new GIcon(G_DEFAULT_ICON);
greenIcon.image = "http://localhost/pointer_image/markerRd.png";
var markerOptions1 = {icon:greenIcon};

    var redIcon = new GIcon(G_DEFAULT_ICON);
redIcon.image = "http://localhost/pointer_image/markerGr.png";
var markerOptions2 = {icon:redIcon};

var yIcon = new GIcon(G_DEFAULT_ICON);
yIcon.image = "http://localhost/pointer_image/markerBl.png";
var markerOptions3 = {icon:yIcon};

here you have to put your marker image from a folder called "pointer_image"

you can change the marker image by chenging the code

by editing this portion of code :--

<script type="text/javascript">
var greenIcon = new GIcon(G_DEFAULT_ICON);
greenIcon.image = "http://localhost/pointer_image/markerRd.png";
var markerOptions1 = {icon:greenIcon};

    var redIcon = new GIcon(G_DEFAULT_ICON);
redIcon.image = "http://localhost/pointer_image/markerGr.png";
var markerOptions2 = {icon:redIcon};

var yIcon = new GIcon(G_DEFAULT_ICON);
yIcon.image = "http://localhost/pointer_image/markerBl.png";
var markerOptions3 = {icon:yIcon};

hope this will help you ,i am also providing the database thi it also in bellow------

在标记上使用 setImage 方法。

Marker[1].setImage('blue-icon.png');

http://gmaps-samples.googlecode.com/svn/trunk/ whackamarker/whackamarker.htm

Use the setImage method on the marker.

Marker[1].setImage('blue-icon.png');

你好，陌生人 2024-08-18 15:49:36

您可以在原始标记上放置具有所需颜色的新标记。此处通过示例解释了此技术：http://esa.ilmari.googlepages.com /hellocolorswitch.htm

You can put a new marker with the desired color over the original marker. This technique, with an example, is explained here: http://esa.ilmari.googlepages.com/hellocolorswitch.htm

如果你使用 gmap3 插件，你可以像这个例子一样。

https://gmap3.net/api-marker.html。

您可以像这样使用所有这些颜色和图标，

https://sites.google.com/site /gmapsdevelopment/

if you are using gmap3 plugin you can do like this example.

https://gmap3.net/api-marker.html.

And you can use all these colours and icons like this,
