在页面加载时将地址传递给Google地图 [英] Passing address to Google Maps on page load

问题描述

使用地理编码初始化Google地图有一些问题。第一个问题是在$ gmap字符串中使用任何逗号，第二个问题是获取gmap_initialize未定义。

 <？php $ gmap =布拉格，捷克共和国我知道一切以外的功能是正确的， ; ？> 
 
< script type =text / javascript> 
函数gmap_initialize（）{
 var geocoder = new google.maps.Geocoder（）; 
 geocoder.geocode（{'address'：<？php echo $ gmap;？>}，function（results，status）{
 if（status == google.maps.GeocoderStatus.OK） {
 var options = {
 zoom：16，
 position：results [0] .geometry.location，
 center：results [0] .geometry.location，$ b $ （map.canElementById（map_canvas），options）; 
 
 var marker = new google.maps.Marker（{
 map：map，
 position：results [0] .geometry.location 
}）; 
} else {
警报（地理编码不成功，原因如下：+状态）; 
} 
}）; 
 
} 
< / script> 
  

解决方案

您是否看过脚本的输出？

我的猜测是这样的：

geocoder.geocode（{地址'：捷克共和国布拉格}，函数（结果，状态）{/ / c $ c>





在你的PHP脚本中，

geocoder.geocode（{'address'：'<？php echo $ gmap;？>'}，function（results，status ）{/ code>

，您可能希望将单引号从 $ gmap 变量。

Having some problems initialising a google map using geocoding. First issue is with any commas being used in the $gmap string, second issue is with getting a "gmap_initialize is not defined". I know everything outside of the function is correct, any ideas?

<?php $gmap = "Prague, Czech Republic"; ?>

<script type="text/javascript">
function gmap_initialize() {
var geocoder = new google.maps.Geocoder();
geocoder.geocode( { 'address': <?php echo $gmap; ?>}, function(results, status) {
  if (status == google.maps.GeocoderStatus.OK) {
    var options = {
      zoom: 16,
      position: results[0].geometry.location,
      center: results[0].geometry.location,
      mapTypeId: google.maps.MapTypeId.ROADMAP
    };
    var map = new google.maps.Map(document.getElementById("map_canvas"), options);

    var marker = new google.maps.Marker({
      map: map,
      position: results[0].geometry.location
    });
  } else {
    alert("Geocode was not successful for the following reason: " + status);
  }
});

}
</script>

解决方案

Did you look at the output of your script?!

My guess is it looks something like:

geocoder.geocode( { 'address': Prague, Czech Republic}, function(results, status) {

In your PHP script, you probably actually want something like:

geocoder.geocode( { 'address': '<?php echo $gmap; ?>'}, function(results, status) {

and you'll probably want to escape single quotes out of the $gmap variable.
