我有一个PHP数组在下面的形式，我试图绘制这些在谷歌地图(v3)在我的网站，但想知道最好的方式来创建标记的代码。下面是我测试硬编码的一些工作代码的示例。
我可以创建一个循环，使列表，但我将不得不检查删除最后一个逗号，否则Javascript将是无效的，觉得这是相当hacky和可能不是最好的方式来做到这一点，我在想，反而会有一些我忽略了，这将允许我传递一个数组，并告诉它什么键来创建Javascript，所有正确格式化?
<例子数组/strong>

Google地图的硬编码Javascript代码-使用数组中的address1, lat和lng。将来可能需要添加更多
var properties = [
['1 Anystreet', 51.5245029, -0.1120882],
['2 Anystreet', 51.5189016, -0.1027654],
['45 Any Road', 51.5189016, -0.1027654]
];
您可以操作PHP数组来模拟Google Maps API的要求:
Array (
[0] => Array (
[address1] => 1 Anystreet London
[lat] => 51.5245029
[lng] => -0.1120882
)
[1] => ...
)
要使其JavaScript可读，只需回显json编码:
<script type="text/javascript">
var locations = <?php echo json_encode($locations_array); ?>;
</script>
这避免了任何字符转义，删除尾随逗号，插入方括号等。
这有一个额外的好处，保持你的数据键，所以你可以访问你的数据如下使用JavaScript:
for(i in locations)
{
var address1 = locations[i].address1;
var lat = locations[i].lat;
var lng = locations[i].lng;
// use address1, lat, lng however you like
}
我总是使用下面的解决方案，它总是有效的。;)
在视图:
<script type="text/javascript">
var properties = [
<?php
$count = count($data);
for ( $i = 1; i <= count; ++$i ) {
$lat = str_replace(',', '.', $data['lat']);
$lng = str_replace(',', '.', $data['lng']);
echo '["' . $data['address1'] . '", ' . $lat . ',' . $lng . ']';
if ( $i < $count ) {
echo ',';
}
}
?>
];
</script>
