我有一個問題,可能已經解決或可能沒有解決過,但我似乎是唯一使用純JavaScript而不是JQuery來完成我簡單的AJAX請求。Zillow數據 - json_encode不工作 - 適用於常規變量
首先這裏是我的AJAX:
function getZestimate(address,csz){
var xmlhttp = new XMLHttpRequest();
var userdata = "address="+address+"&csz="+csz;
xmlhttp.open("POST","../wp-content/themes/realhomes/submit_address.php",true);
xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xmlhttp.onreadystatechange = function(){
if(xmlhttp.readyState == 4 && xmlhttp.status == 200){
retrieve = JSON.parse(xmlhttp.responseText);
document.getElementById("zestimateArea").innerHTML =
'<div id="zillowWrap">
<div id="logoANDtag">
<a href="http://www.zillow.com"><img src="http://www.zillow.com/widgets/GetVersionedResource.htm?path=/static/logos/Zillowlogo_150x40.gif" width="150" height="40" alt="Zillow Real Estate Search" id="ZillowLogo" /></a>
<span id="zestimateTag">Zestimate®</span>
</div>
<span id="zestimatePrice">'+retrieve[0]+'</span>
</div>
<div id="zillowDisclaimer">
<span>© Zillow, Inc., 2006-2014. Use is subject to <a href="http://www.zillow.com/corp/Terms.htm">Terms of Use</a></span
<span>What’s a <a href="http://www.zillow.com/wikipages/What-is-a-Zestimate">Zestimate?</a>
</div>';
}
else{
document.getElementById("zestimateArea").innerHTML = "Error!"
}
}
xmlhttp.send(userdata);
document.getElementById("zestimateArea").innerHTML = "Generating...";
return false;
}
接下來,這裏是我的PHP:
<?php
$zillow_id = '1234';
$search = $_POST['address'];
$citystate = $_POST['csz'];
$address = urlencode($search);
$citystatezip = urlencode($citystate);
$url = "http://www.zillow.com/webservice/GetSearchResults.htm?zws-id=".$zillow_id."&address=".$address."&citystatezip=".$citystatezip;
$result = file_get_contents($url);
$data = simplexml_load_string($result);
$zpidNum = $data->response->results->result[0]->zpid;
$zurl = "http://www.zillow.com/webservice/GetZestimate.htm?zws-id=".$zillow_id."&zpid=".$zpidNum;
$zresult = file_get_contents($zurl);
$zdata = simplexml_load_string($zresult);
$zestimate=$zdata->response->zestimate->amount;
$street=$zdata->response->address->street;
$city=$zdata->response->address->city;
$state=$zdata->response->address->state;
$zip=$zdata->response->address->zip;
$one='one';
$two='two';
header("Content-Type: application/json; charset=utf-8", true);
echo json_encode(array($zestimate,$street));
?>
什麼在我的AJAX返回的是[object Object]
在我的控制檯中沒有錯誤。
但是,請參閱2變量$one
和$two
?如果我將它們放在json_encode
,如echo json_encode(array($one,$two));
,它會像它應該那樣返回one
。我不確定Zillow數據有什麼不同。我可以echo
它個別沒有問題。但我需要發送多個值才能使用。有任何想法嗎?
的SimpleXML節點可能需要轉換爲字符串第一。如果您執行'$ zestimate =(string)$ zdata-> response-> zestimate-> amount,它會起作用嗎? $ street =(string)$ zdata-> response-> address-> street;'?其背後的原因隱藏在手冊[here]中(http://php.net/manual/en/simplexml.examples-basic.php#example-6046)。這是因爲SimpleXML節點是對象,所以'json_encode'不能像你期望的那樣處理它們。 – drew010
@ drew010是的。把它放在答案中,我會標記它。謝謝! – Christine268
