'未捕获InvalidValueError'(:setCenter:不是LatLng或LatLngLiteral对象) [英] 'Uncaught InvalidValueError' (: setCenter: not a LatLng or LatLngLiteral object)
问题描述
我开始了解PHP和JavaScript,将它们混合在HTML中,并使用Google Maps API(版本3)。
我计算了如何放置各种标记,但控制台会给我一个错误:未捕获InvalidValueError:setCenter:不是LatLng或LatLngLiteral对象。
我认为这是因为在循环中创建的var不完全是需要的对象,而是一个字符串,尽管这使我困惑,但我不知道我是否正确。如果有人能让我走上正确的道路,我将非常感激。
预先感谢。
这是我的代码:
(顺便说一下,我循环的数组是一个数组,其中包含一些数组。它遵循这个模式,总共有6个地方):
$ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ array $(
array(
'Location'=> array(
'Title'=>'Place',
'Description'=>'Some Place',
'Image'=> ;'pin1.png',
'Latitude'=> '20 .681775',
'Longitude'=>' - 103.351479'
)
),...
(它会继续...)。

它同样值得注意的是,Google Maps v3似乎没有清理设置标记的数据值。这似乎在过去几周发生了变化,因为之前我将图标高度作为字符串传递给Google的MarkerImage函数(它来自JSON)。但是这突然爆发了,因为它不是一个数字。
显然,解决方案是传入一个数字,或者将数据包装在 parseInt()
或 parseFloat()
,以便API获取数字或浮点数。 Google应该正在清理其数据,但事实并非如此。
var custom_icon = new google.maps.MarkerImage(
icon_path,
google.maps.Size(
parseInt(icon_options.width),
parseInt(icon_options.height)
),
new google.maps .Point(
parseFloat(icon_options.origin_x),
parseFloat(icon_options.origin_y)
),
new google.maps.Point(
parseFloat(icon_options.anchor_x ),
parseFloat(icon_options.anchor_y)
)
);
I'm starting to know PHP and JavaScript, mixing them in HTML and using Google Maps API (version 3).
I figured how to 'put' various markers but the console will throw me an error:
" Uncaught InvalidValueError: setCenter: not a LatLng or LatLngLiteral object ".
I think it's because the var created in the loop is not exactly the object needed but instead a string, though this confuses me, I don't know if I'm right. I'd appreciate it a lot if anyone could set me in the right path.
Thanks in advance.
This is my code: (By the way, the array I'm looping is an array with an array with an array, here's some of it. It follows the pattern, there are in total 6 'places'):
$locations = array(
array(
'Location' => array(
'Title'=>'Place',
'Description'=>'Some Place',
'Image'=>'pin1.png',
'Latitude'=>'20.681775',
'Longitude'=>'-103.351479'
)
),…
(It continues…).

And here's a screenshot of that var assigning part: " http://cl.ly/image/1d3e2J360t3y "
It is also worth noting that Google Maps v3 doesn't appear to sanitize the data values for setting markers. This seems to have changed in the last few weeks, because previously I was passing in icon height as a string for google's MarkerImage function (it is coming from JSON). But that suddenly broke because it wasn't a "number".
Obviously the solution is to pass in a number, or wrap your data in parseInt()
or parseFloat()
so that the API gets a number or float. Google "should" be sanitizing it's data but it isn't.
var custom_icon = new google.maps.MarkerImage(
icon_path,
new google.maps.Size(
parseInt(icon_options.width),
parseInt(icon_options.height)
),
new google.maps.Point(
parseFloat(icon_options.origin_x),
parseFloat(icon_options.origin_y)
),
new google.maps.Point(
parseFloat(icon_options.anchor_x),
parseFloat(icon_options.anchor_y)
)
);
