我已经阅读了关于这个问题的大部分SA问题,但没有一个解决了我的问题.
以下代码将JavaScript数组传递给PHP5.这工作正常,但是当我将一个PHP数组返回给ajax代码时,a
parserror: unexpected token "[" is returned.
JS
$(function () {
translate($("h1,p"));
function translate(selection$) {
var elements = [];
for (i = 0; i < selection$.length; i++) {
elements.push(selection$.get(i).outerHTML);
}
var jString = JSON.stringify(elements);
$.ajax({
url: 'test.PHP',type: 'post',data: { 'data': jString },cache: false,dataType: 'json',success: function (data,status) {
$("#after").append(data);
},error: function (xhr,desc,err) {
alert("Details: " + desc + "\nError: " + err + "\n" + xhr.responseText);
}
}); // end ajax call
}
});
传递的字符串数组是
["jQuery Translator","Hello World"]
PHP
编辑
完整的PHP代码是：
<?PHP
ini_set('display_errors',1);
ini_set('display_startup_errors',1);
error_reporting(E_ALL);
if('POST' == $_SERVER['REQUEST_METHOD'])
{
include 'HttpTranslator.PHP';
include 'AccesstokenAuthentication.PHP';
if (!empty($_POST['data'])) {
$elements = json_decode($_POST['data']);
}
$auth = new AccesstokenAuthentication();
$authHeader=$auth->authenticate();
$fromLanguage = "en";
$toLanguage = "es";
$contentType = 'text/html';
$category = 'general';
//Create the Translator Object.
$translatorObj = new HTTPTranslator();
foreach ($elements as $element) {
$params = "text=".urlencode($element)."&to=".$toLanguage."&from=".$fromLanguage;
$translateUrl = "http://api.microsofttranslator.com/v2/Http.svc/Translate?$params";
//Get the curlResponse.
$curlResponse = $translatorObj->curlRequest($translateUrl,$authHeader);
//Interprets a string of XML into an object.
$xmlObj = simplexml_load_string($curlResponse);
$translated = array();
foreach((array)$xmlObj[0] as $val){
array_push($translated,$val);
}
header('Content-type: application/json');
var_export($translated);
}
}
?>
xhr.responseText是
"["<h1>jQuery Traductor<\/h1>"]["<p>Hola mundo<\/p>"]"
这对我来说看起来不像json.我不是PHP5专家,但怀疑我没有正确填写数组.任何帮助是赞赏.
解决方法
移动
header('Content-type: application/json');
var_export($translated);
在$元素的foreach之外.
还初始化$translated = array();之前的元素元素.
喜欢这个：
$translated = array();
foreach ($elements as $element) {
$params = "text=".urlencode($element)."&to=".$toLanguage."&from=".$fromLanguage;
$translateUrl = "http://api.microsofttranslator.com/v2/Http.svc/Translate?$params";
//Get the curlResponse.
$curlResponse = $translatorObj->curlRequest($translateUrl,$authHeader);
//Interprets a string of XML into an object.
$xmlObj = simplexml_load_string($curlResponse);
foreach((array)$xmlObj[0] as $val){
array_push($translated,$val);
}
}
header('Content-type: application/json');
var_export($translated);
