我正在尝试更新某个项目，我不知道为什么var latitude = 0;
var longitude = 0;
function getLocation() {
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(displayLocation);
} else {
alert("Geolocation is not supported by this browser.");
}
}
function displayLocation(position) {
latitude = position.coords.latitude;
longitude = position.coords.longitude;
return;
}
jQuery(document).ready(function($) {
$.ajax({
url : "http://api.wunderground.com/api/7c5cbc3e4db2885a/geolookup/conditions/q/" + latitude + "," + longitude + ".json",
dataType : "jsonp",
success : function(parsed_json) {
var location = parsed_json['location']['city'];
var temp_f = parsed_json['current_observation']['temp_f'];
var desc = parsed_json['current_observation']['weather'];
var wind_dir = parsed_json['current_observation']['wind_dir'];
("Current temperature in " + location + " is: " + temp_f);
$('#location').html(location);
$('#temp_f').html(temp_f);
$('#desc').html(desc);
$('#wind_dir').html(wind_dir);
$('#icon_url').attr('http://icons.wxug.com/i/c/i/clear.gif', img);
}
});
});
返回'0。
一些数据，在检查时似乎正确：
$q->affected_rows - var_dump($query_parts)
string(40) "item_description = ?, item_publisher = ?" - var_dump($prep)
string(3) "sii"
var_dump($values) array(3) {
[0]=>
&string(12) "Description"
[1]=>
&string(1) "1"
[2]=>
&string(3) "729"
}
- var_dump($q)
bool(true)
