谷歌地图标记窗口

Question

我正在尝试在我的Google地图标记窗口中添加一个链接。但我的代码只显示标记和窗口，但它不显示链接。

我想加入这一行的链接：

$marker['infowindow_content'] = "<?php echo anchor('index/get_by_id/$id',{$row->subject} on {$row->address}')?>"; 

当链接被点击它进入我的索引控制器的一些功能。 但为什么链接没有出现在窗口中。 （仅在地图部分）

public function ll($id = '') 
    { 

    $sql = $this->db->get('info'); 
    if ($sql->num_rows() >0) { 
     return $sql; 
    } 
    else{ 
     return null; 

    } 
      } 

从我的代码生成的HTML：：

控制器：

    function index() 
{ 


    if(empty($_POST)){ 
    $this->load->helper('form'); 
    $this->googlemaps->initialize(); 
    $marker = array(); 
    //$this->main_model->get_map(); 

    if($result = $this->main_model->ll()){ 
     //var_dump($result); 
     foreach($result->result() as $row) { 
      //var_dump($row); 
      //$data[]=$row; 
      $marker['position'] = "{$row->lat},{$row->lng}"; 
      $id=$row->id; 
      $marker['infowindow_content'] = "<?php echo anchor('index/get_by_id/$id',{$row->subject} on {$row->address}')?>"; 

      $marker['animation'] = 'DROP'; 
      //var_dump($marker['position ']); 
      $this->googlemaps->add_marker($marker); 
     } 
    } 


    //$this->googlemaps->add_marker($marker); 
    $data['map'] = $this->googlemaps->create_map(); 
    $data['list'] = $this->main_model->getdata(); 
    $this->load->view('main_view',$data); 
} 


}

的问题是与该线：

$marker['infowindow_content'] = "<?php echo anchor('index/get_by_id/$id',{$row->subject} on {$row->address}')?>"; 

InfoWindow的内容是一个包含实际HTML代码的字符串。在你的情况下，<?php块被忽略，因为你可以在生成的HTML看到：

marker_0.set("content", "<?php echo anchor('index/get_by_id/1',street problem on something home)?>"); 

它必须是：

marker_0.set("content", "<a href='index/get_by_id/1'>street problem on something home</a>"); 

试试这个：

<?php 
    $subject = $row->subject; 
    $address = $row_>address; 
?> 

var index = '<?php echo $id; ?>'; 
var subject = '<?php echo $subject; ?>'; 
var address = '<?php echo $address; ?>'; 

$marker['infowindow_content'] = "<a href='index/get_by_id/" + index + "'>" + subject + " on " + address + "</a>";
