[英]returning json message on ajax success
I have a jquery function which performs an update via ajax我有一个 jquery 函数,它通过 ajax 执行更新
the update works successfully, (i can check this in firebug network response), but i cant get a response message, (by alert, or by console)更新成功,(我可以在萤火虫网络响应中检查这个),但我无法得到响应消息,(通过警报或控制台)
here is my code snippet...这是我的代码片段...
$('#mcbatchsubscribe').on('click', 'a.ajaxresub', function (e) {
e.preventDefault();
var email = $(this).attr('emailvalue');
$.ajax ({
url: '/admin/ajax/ajax_resubscribe.php',
data: {email: email},
dataType: 'json',
success: function (json) {
console.log("success", json);
//alert(json)
}
} );
} );
If i open up firebug, the console returns nothing, - the network header shows the correct ajax path and parameter, the network response shows the ajax success message, 'Resubscribed Success' -what the ajax page does is to run a list subscribe on the email parameter on mailchimp, and this definitely works.如果我打开 firebug,控制台什么都不返回, - 网络标头显示正确的 ajax 路径和参数,网络响应显示 ajax 成功消息,“重新订阅成功” - ajax 页面所做的是运行列表订阅mailchimp 上的电子邮件参数,这绝对有效。 here is the ajax snippet...
这是ajax片段...
...if ($rsemail->TotalRows > 0) { // Trigger if there is a matching row
$merge_vars = array(
'FNAME'=> $rsemail->getColumnVal("MemberFirstName"),
'LNAME'=> $rsemail->getColumnVal("MemberLastName")
);
$MailChimp = new \Drewm\MailChimp($api_key);
$subscriberesult = $MailChimp->call('lists/subscribe',
array('id' => $list_id,
'email' => array('email'=>$rsemail->getColumnVal("MemberEmail")),
'merge_vars' => $merge_vars,
'double_optin' => true,
'update_existing' => true,
'replace_interests' => false,
'send_welcome' => false
));
if ($subscriberesult ['email'] != $rsemail->getColumnVal("MemberEmail")) {
echo nl2br(($subscriberesult ['code'])."\r\n");
echo nl2br(($subscriberesult ['name'])."\r\n");
echo nl2br(($subscriberesult ['error'])."\r\n");
} else {
echo 'Resubscribed success';
}
} else {
echo 'Resubscribe failure - Email not found';
} }
I think I am making progress我觉得我在进步
I changed success: function (json) to complete: function (json)我改成成功:函数(json)来完成:函数(json)
i now get我现在得到
Object {readyState: 4, responseText: "Resubscribed success", status: 200, statusText: "OK"}对象 {readyState: 4, responseText: "Resubscribed success", status: 200, statusText: "OK"}
The problem问题
Your AJAX request contains the following setting:您的 AJAX 请求包含以下设置:
dataType: "json"
The response text is not a valid json
text.响应文本不是有效的
json
文本。 When jQuery tries to parse the response as json -> it fails and skips the success
callback...当 jQuery 尝试将响应解析为 json -> 它失败并跳过
success
回调...
More about that in jQuery AJAX documentation更多关于jQuery AJAX 文档
Solution (1)解决方案 (1)
Drop the dataType:'json'
from your ajax parameters- it will prevent jQuery from trying to parse your response string to a json
object (and fail doing so...)从您的 ajax 参数中删除
dataType:'json'
它会阻止 jQuery 尝试将您的响应字符串解析为json
对象(并且这样做失败......)
OR或者
Solution 2解决方案2
Change the responseText
in your server code to something like:将服务器代码中的
responseText
更改为:
"{result: 'Resubscribed success'}"
This will pass jQuery's json validation, and your success
handler will be invoked.这将通过 jQuery 的 json 验证,并且您的
success
处理程序将被调用。
