ExtJS:属性列表后缺少 } 但我没有看到任何代码错误
加载失败 -- 参数:[对象 api=对象,对象请求=对象读取器=对象范围=对象,对象 tId=0 状态=200 statusText=OK,语法错误:在属性列表之后丢失 } 消息=丢失 } 在属性列表之后]
I通过向我的商店添加异常来得到该错误,但在我的代码中没有看到任何真正的错误......也许另一双眼睛会有所帮助。
php:
case 'messages':
if(isset($_SESSION['id'])){
$stmt = $dbh->prepare("Select ID, ReceivedAt, Message from SystemEvents Limit 100");
$stmt->execute();
while($tmp = $stmt->fetch()){
$y .= '{"ID":"'.$tmp['ID'].'","ReceivedAt":"'.$tmp['ReceivedAt'].'","Message":"'.$tmp['Message'].'"},';
}
$y = trim($y,',');
if(isset($_REQUEST['callback'])){
echo $_REQUEST['callback'].'({"dates":['.$y.']});';
}else{
echo '{"dates":['.$y.']}';
}
}else{
if(isset($_REQUEST['callback'])){
echo $_REQUEST['callback'].'({success: false, data{"error_title": "Error", "errormsg": "Cannot display dates"}})';
}
else{
echo '{success: false, data{"error_title": "Error", "errormsg": "Cannot display dates"}}';
}
}
break;
extjs:
Ext.onReady(function(){
var logStore = new Ext.data.JsonStore({

}
});

我不认为发布我的 php 的其余部分是相关的,因为它一切正常,但希望有人能发现我的坏眼睛无法发现的东西。
load failed -- arguments: [Object api=Object, Object request=Object reader=Object scope=Object, Object tId=0 status=200 statusText=OK, SyntaxError: missing } after property list message=missing } after property list]
I got that error by adding an exception to my store but don't see any real error in my code...maybe another set of eyes will help.

I don't think posting the rest of my php would be relevant since it all works but hopefully someone can spot something that my bad eyes cannot.

我在这里看到一个额外的逗号:
也在 LogGrid 上。可能就是这样
编辑:如果出现错误,从 PHP 发回的响应看起来不会是有效的 JSON
data{"error_title"
是错误的,应该是data:{" error_titel"
你真的应该看看在 PHP 中构建对象/数组并使用 json_encode 回显它们,而不是手动构建 JSON。
I see an extra comma here:
Also on the LogGrid. That might be it
EDIT: The response sent back from PHP does not look like it will be valid JSON if there is an error
data{"error_title"
is wrong, should bedata:{"error_titel"
You really should look at building objects/arrays in PHP and echo these using json_encode instead of building JSON manually.
顺便说一句:为了找到杂散的逗号,我使用以下模式进行搜索:
\,\s*(}|])
这可以节省大量时间,特别是因为不同的浏览器比其他浏览器对错放的逗号更强大。
BTW: To find stray commas, I do a search with the following pattern:
\,\s*(}|])
This saves heaps of time, especially since different browsers are more robust than others to misplaced commas.
