javascript - 页面内容无法加载并且未捕获语法错误 : Unexpected token ;

Question

您好，我们网站的某些部分一直在加载，当我尝试通过 Inspect 元素检查时，出现错误 Uncaught SyntaxError: Unexpected token ;根据检查，我对这段代码有问题

<script>
<?php echo "var place =".$city.";"; ?>
jQuery(document).ready(function(){
//console.log(place);
getLocation();
//get_locations(place.city,'<?php echo BASE_URL.'clinics/get_near_locations'; ?>');
});

function getLocationByCity(data){
var city = place.city;
var url = '<?php echo BASE_URL.'clinics/get_near_locations'; ?>';

//  if(city!='false')
//  jQuery('#current-city').html('Current City: '+city);


jQuery.ajax({
            url:url,
            type: 'POST',
            dataType: 'html',
            data:'city='+city,
            beforeSend: function(){
                jQuery('.button').html('<span>Please wait...</span>');
            },
            success: function(data){

                jQuery('#clinic-locations').html(data);
            }
});

}


function getLocation()
{

if (navigator.geolocation){
        navigator.geolocation.getCurrentPosition(getLocationByLatLong,errorHandler,{timeout:6000});
}else{
    getLocationByCity();
}
}

function errorHandler(err)
{
console.log(err);
console.log('errorHandler');
getLocationByCity();
}



  function getLocationByLatLong(position)
 {

jQuery.ajax({
            url:'<?php echo BASE_URL.'clinics/get_near_locations'; ?>',
            type: 'POST',
            dataType: 'html',
            data:'latitude='+position.coords.latitude+'&longitude='+ position.coords.longitude,
            beforeSend: function(){
                jQuery('.button').html('<span>Please wait...</span>');
            },
            success: function(data){
                jQuery('#clinic-locations').html(data);
            }
});
}

我也尝试从第二行删除 ; 但没有运气。有人可以帮忙吗？谢谢!

您的问题在第一行:

<?php echo "var place =".$city.";"; ?>

字符串应该用引号或撇号括起来，因此将其更改为

<?php echo "var place = '$city';"; ?>
