我有一个页面,我想每隔一分钟刷新一次div,而不刷新整个page.Div从一个php文件中获取数据,他们在另一个xml文件中计算更大的价格。我读了最好的方法是ajax请求。ajax请求响应虚假数据
我的Ajax代码:
<script type="text/javascript">
$(function(){
var name = $("#product").val();
$.ajax({
type: "GET",
url: "maxPrice.php",
dataType: "text",
data: {'product_name' : name},
error: function(XMLHttpRequest, textStatus, errorThrown) {
alert(textStatus);
},
success:function(result) {
alert(result);
}
});
});
</script>
php文件:
<?php
$product_name = $_GET['product_name'];
$loop = 0;
$auction_price_db = 0;
$id_product = id_from_product_name($product_name);
$doc = new DOMDocument();
$doc->load('C:/wamp/www/store/connections/auctions.xml');
$xpath = new DOMXPath($doc);
$xml_offers = simplexml_load_file('C:/wamp/www/store/connections/offers.xml');
$xml_auctions = simplexml_load_file('C:/wamp/www/store/connections/auctions.xml');
foreach ($xml_auctions->auction as $auction){
if ($auction->auction_id == $id_product) {
$auction_price_db = (string)$auction->start_price;
$item = $loop;
break;
}
$loop++;
}
foreach ($xml_offers->offer as $offer){
if ($offer->id_product == $id_product) {
$user_offer = (string)$offer->price;
if ($user_offer > $auction_price_db) {
$parent = $doc->getElementsByTagName('auction')->item($item);
$query = $xpath->query('start_price',$parent);
$query->item(0)->nodeValue = $user_offer;
$doc->save('C:/wamp/www/store/connections/auctions.xml');
$xml_products = simplexml_load_file('C:/wamp/www/store/connections/products.xml');
foreach ($xml_products->product as $product){
if ($id_product == $product->product_id) {
$product->price = $user_offer;
$xml_products->asXML('connections/products.xml');
}
}
$response = "{\"user_offer\":\"".$user_offer."\"}";
}
}
}
echo <<<HERE_DOC
$response
HERE_DOC;
?>
在阿贾克斯的成功,我有一个警惕,如果从阿贾克斯的数据与此right.But它的响应。 。

为什么我得到这个反应呢?如果我尝试删除maxPrice所有代码和回声只有$ PRODUCT_NAME,我在ajax请求中传递它我得到正确的数据。
'未定义功能id_from_product_name()在C:\ WAMP \ WWW \店\ maxPrice.php上线6'似乎成为问题,所以'$ id_product = id_from_product_name($ product_name);'正在轰炸 – MonkeyZeus
有一个错误,你正在发送回调用堆栈。错误是在那里“致命的错误:调用未定义的函数id_from_product_name()在C:\ wamp \ www \ store \ maxPrice.php在线..” – Gjohn
为什么?我知道这个函数工作正常.id_from_product_name是一个另一个PHP文件。我必须把它放在相同的? – user3071235
