我正在尝试创建绑定(bind)并缩放到我的标记。但我有我在行中提到的错误:
bounds.extend(markers[i].position);
当我在for循环中设置markers.length的长度时，它会给出太多递归错误
我显示了所有标记，但它们没有缩放和限制，并且我也遇到了我刚才提到的错误。
我执行此操作的代码是:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">

function initialize() {
//var markers = new Array();
var markers = [];
$.ajax({
type: 'GET',
url: './Content/TextFile/LongLat.txt',
//filereader\filereader\Content\TextFile\LongLat.txt
// url: './distinctGimeiNo.txt',
dataType: 'text',
}).success(function (data) {
var infowindow = new google.maps.InfoWindow();
var marker;
var s2 = data.replace(/^.*$/, " ").replace(/\r\n/g, " ");
var array = s2.split(/[ ]+/g);
var test = [].concat.apply([], array.map(function (array) { return array.split(/\s+/); }))
var col1 = [];
var col2 = [];
var col3 = [];
var j = 0;
// var currentLocation =
var mapOptions =
{
zoom: 2,
center: new google.maps.LatLng(73, 23),
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
for (var i = 0; i <= test.length - 3; i = i + 3) {
col1[j] = test[i];
col2[j] = test[i + 1];
col3[j] = test[i + 2];
var myLatlng = new google.maps.LatLng(col3[j], col2[j]);
marker = new google.maps.Marker(
{
position: myLatlng,
map: map,
title: 'Hello World! ' + col1[j]
});
markers.push(marker);
console.log("test2");
j++;
}
function AutoCenter() {
var bounds = new google.maps.LatLngBounds();
for (var i = 0; i < markers.length; i++) {
bounds.extend(markers[i].position);
}
map.fitBounds(bounds);
}
AutoCenter();
})
}
google.maps.event.addDomListener(window, 'load', initialize);
console.log("Check finished2");
</script>

有人可以告诉我问题的解决方案吗？
最佳答案
您的第一组坐标无效。当您将无效坐标放入 google.map.LatLngBounds 时，结果将无法用于配置 map (它会生成您报告递归过多的错误)。
数据的第一行(取自 this question )不包含数字。
如果我跳过第一个条目，它对我有用:
for (var i = 3; i <= test.length - 3; i = i + 3) {
col1[j] = test[i];
col2[j] = test[i + 1];
col3[j] = test[i + 2];
var myLatlng = new google.maps.LatLng(col3[j], col2[j]);
marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: 'Hello World! ' + col1[j]
});
markers.push(marker);
console.log("test2"+marker.getPosition().toUrlValue(6));
j++;
}
