Question

我正在使用Symfony 2.3，twig和这个插件location picker来显示地图。我嵌入了一组地址。每个地址表都有一张地图。用户可以手动添加地址表单。然后谷歌地图显示正确的第一个地址，但添加一个借调地址时，地图不会显示。 chrome控制台不显示任何错误。

vigilance_point_collection-prototype.html.twig文件：

Answer 1

我猜的问题在于：

$('#us3').locationpicker({

... 

<div id='us3' style='width: 550px; height: 400px;'></div>
{% for row in prototype %}

所以你有一个你正在加载地图的div。您可能需要为每个地址在不同的div上调用.locationpicker（）构造函数，并在每个地址的for循环内创建一个唯一命名的div。 e.g。

$('#us{{ id }}').locationpicker({

... 

{% for row in prototype %}
    <div id='us{{ id }}' style='width: 550px; height: 400px;'></div>
