这是我的问题。我想将不同的图像设置为融合表给出的标准标记。我从包含我的点“(坐标,坐标)”的列中提取数据但是当我将此坐标与标记相关联时,这个坐标没有显示!我认为解决方案非常简单,但我无法得到它:(。请阅读此代码中间的“这是问题”部分以获得清晰的想法。谢谢!!!!
function initialize() {
geocoder = new google.maps.Geocoder();
map = new google.maps.Map(document.getElementById('map_canvas'), {
center: new google.maps.LatLng(46.06454, 13.23561), //the center lat and long
zoom: 9, //zoom
mapTypeId: google.maps.MapTypeId.ROADMAP //the map style
});
//make gviz request
setData();
}
/* GVIZ - get data from Fusion Tables */
function setData() {
//create a viz query to send to Fusion Tables
var query = new google.visualization.Query('http://www.google.com/fusiontables/gvizdata?tq=' + encodeURIComponent("SELECT dove FROM 781907"));
//set the callback function that will be called when the query returns
query.send(getData);
}
function getData(response) {
numRows = response.getDataTable().getNumberOfRows();
for (i = 0; i < numRows; i++) {
var row = response.getDataTable().getValue(i,0);
codeAddress(row);
}
}
var geocoder;
function codeAddress(latlng) {
// HERE IS THE PROBLEM!!!!
// Test show correctly "(lat,lng)" BUT no marker showed on the map!
document.getElementById("test").innerHTML = latlng;
geocoder.geocode( { 'latLng': latlng}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
var marker = new google.maps.Marker({
map: map,
position: latlng
//icon: new google.maps.MarkerImage("http://www.google.com/images/icons/product/fusion_tables-32.png")
});
}
});
}
更新:基于@Trott 的回答,可能是这样的?但仍然没有运行。有什么建议吗?
function getData(response) {
numRows = response.getDataTable().getNumberOfRows();
//create an array of row values
for (i = 0; i < numRows; i++) {
rowtext = response.getDataTable().getValue(i,0);
var strArr[] = rowtext.split(",");
document.getElementById("via").innerHTML = rowtext;
row = new google.maps.LatLng(strArr[0],strArr[1]);
codeAddress(row);
}
}
