我在我的网页上使用谷歌标记。纬度、经度、名称和详细信息是使用 php 页面从数据库中获取的，然后 m 使用 $.post 方法在 jquery 上使用它。 

<?php 

//Basic environment setup (error handling and logging, cookies/sessions, php directives         etc)
require_once $_SERVER['DOCUMENT_ROOT'] . '/../Config/path_config.php';
require_once C_PATH_UTILITY_MANAGER_PAGESETUP;
Page_Setup_Manager::setDefaultPageSettings();

require_once C_DIR_UTILITY_EVENTS_DATAACCESS;

$eventsdats=Eventsdata::getevents();
$temp=array();


foreach($eventsdats as $singlemapevent)
{
array_push($temp,array($singlemapevent['ename'],
     (floatval($singlemapevent['latitude'])),
    (floatval($singlemapevent['longitude'])),
    ($singlemapevent['edate']),
    ($singlemapevent['etime']),
    ($singlemapevent['edetail'])
    ));
}
echo json_encode($temp);

//Result[["Second Event",19.0554748,72.8497017,"17-12-2012","17:57 ","This is the  

social detail;"],["Demo Event",19.2097381,72.8737017,"08-12- 2012","09:34 ","This event  

was held in bhayander by ganesh mandhre"],]
?>

标记在 Firefox 中可见，但在 chrome 和 safari 中不可见。错误是什么？我错误地使用了 json 吗？

当你得到你的 json 数据时，你必须在回调中处理它们。在这里，您在 ajax 调用完成之前显示地图和标记。将此渲染移至done回调。
