[英]Why is my AJAX call success function not firing a java script alert?
$.ajax({
url: '../api/notifications/deleteNotification?userId=' + userId + '¬ificationId=' + notificationId,
type: 'DELETE',
success: function()
{
CreateNotificationTree(userId);
alert('Delete successful.');
},
failure: function()
{
alert('Delete failed.');
}
});
The function CreateNotificationTree(userId);
函数
CreateNotificationTree(userId);
that is inside the success function of the ajax call above DOES fire. 在DOES上方执行ajax调用的成功函数中。 However, the Alert is not firing after.
但是,警报不会在之后触发。 Does anybody know why?
有人知道为什么吗? I have tried to use multiple browsers as well.
我也尝试过使用多个浏览器。
EDIT - found out I'm running into this error when the AJAX call executes: 编辑-发现执行AJAX调用时遇到了此错误:
Uncaught TypeError: Cannot read property 'uid' of undefined kendo.web.min.js:23

Log the error to your console. 将错误记录到控制台。
You do not see the alert if ajax fails method as jQuery
does not identify the failure
method. 如果ajax失败方法,您将看不到警报,因为
jQuery
无法识别failure
方法。
Use a error
callback to log the error. 使用
error
回调记录错误。
Also use console.log
instead of alert
which is annoying and stops the flow of execution 还请使用
console.log
而不是令人讨厌的alert
并停止执行流程
failure: function(){
alert('Delete failed.');
}
supposed to be 应该是
error: function(){
alert('Delete failed.');
}
And use done
and fail
instead of success
and error
callbacks as the latter as deprecated as of version 1.8
并使用
done
和fail
代替success
和error
回调,因为后者在版本1.8
已弃用
$.ajax({
url: '../api/notifications/deleteNotification?userId='
+ userId + '¬ificationId=' + notificationId,
type: 'DELETE'
}).done(function () {
CreateNotificationTree(userId);
console.log('Delete successful.');
}).fail(function (jqXHR, status, error) {
console.log("Error : " + error);
});
Use the arguments
that are passed to the callbacks and you ll be able to pinpoint the error. 使用传递给回调的
arguments
,您将可以查明错误。
