parsererror / SyntaxError:意外的令牌<
I've searched a lot for this but the answers that I find doesn't work but I think that the problem is mine.
JavaScript:
$.ajax({
type: 'POST',
url: url,
data: data,
dataType: 'json',
success: function(response) {
if(response.status == true) {
alert('ok');
} else {
alert('error');
}
},
error: function(xhr, desc, err) {
console.log(xhr);
console.log("Details: " + desc + "
Error:" + err);
}
});
PHP
if(User::addFavLater($id, $user, 'favs')) {
$result = array("status" => true);
} else {
$result = array("status" => false);
}
header('Content-type: application/json');
echo json_encode($result);
So, this is an excerpt of code that I have and I think can you realising. I want PHP to send a JSON response into JavaScript but this is not happening and JavaScript gives me this error:
parsererror / SyntaxError: Unexpected token <
I'm using the 2.1.1 version of JQuery.
P.S.: Sorry for my english.
我为此搜索了很多,但我找到的答案不起作用,但我认为这个问题 是我的。 p>
JavaScript: p>
$ .ajax({
type:'POST',
url:url,
data: data,
dataType:'json',
success:function(response){
if(response.status == true){
alert('ok');
} else {
alert(' 错误');
}
},
错误:function(xhr,desc,err){
console.log(xhr);
console.log(“Details:”+ desc +“
}: “+ err);
}
});
code> pre>
PHP p>
if(User ::) addFavLater($ id,$ user,'favs')){
$ result = array(“status”=&gt; true);
} else {
$ result = array(“status”=&gt; false) ;
}
header('Content-type:application / json');
echo json_encode($ result);
code> pre>
所以,这是一个 我所拥有的代码摘录,我想你能意识到这一点。 我希望PHP将JSON响应发送到JavaScript,但这不会发生,JavaScript会给我这个错误: p>
parsererror / SyntaxError:Unexpected token&lt;
code> pre>
我正在使用2.1.1版本的JQuery。 p>
PS:抱歉我的英文。 p>

In the method $.ajax
, the success callback receives the response of the server (the JSON file) in the variable data
(success:function(data){...}
). Thus, try to recover the value you want from this variable (in your case, something like data.response
rather than just response
).
