In my else block, the second line does not appear to be running. It runs setHelperText but seems to ignore setAlertValue.
const [alertValue, setAlertValue] = useState("error");
const [errValue, setErrorValue] = useState("Error State");
const [helperText, setHelperText] = useState('Input "success" to remove error');
const handleChange = (e) => {
setErrorValue(e.target.value);
if (e.target.value === "success") {
setAlertValue(null);
setHelperText("Update input to re-enable error");
} else
setHelperText('Input "success" to remove error');
setAlertValue("error"); // this line does not run
};
<TextField
label="Error State"
message="this is an ERROR message"
alert={alertValue}
value={errValue}
onChange={handleChange}
helperText={helperText}
/>

Curly braces are missing in your code. It should be like this:
if (e.target.value === "success") {
setAlertValue(null);
setHelperText("Update input to re-enable error");
} else {
setHelperText('Input "success" to remove error');
setAlertValue("error");
};

In the code below, I've defined a function called checkPassword(), which takes in a single argument, passwordCorrect, which will be either true or false.
I've also defined two variables, accessGranted and message, which currently have no values (they're undefined) and will be overwritten and defined by your if statement if you've written it correctly.
I need to write an if statement inside the function that updates the two variables, accessGranted (a boolean), and message (a string), to meet the requirements below
Requirements:
1) If passwordCorrect is true, accessGranted should have a value of true and message should have a value of 'Welcome to the admin panel!'
2) In any other case, accessGranted should have a value of false and message should have a value of 'Wrong password.'
var accessGranted;
var message;
function checkPassword(passwordCorrect) {
if passwordCorrect == true {
accessGranted = true;
message = "Welcome to the admin panel!";
}
else {
accessGranted = false;
message = "Wrong password."
}
}
console.log('Access Granted:', accessGranted);
console.log('Message:', message);

You need to call the function and fix your syntax error. If statements need parentheses in javascript.
let accessGranted;
let message;
function checkPassword(passwordCorrect) {
if (passwordCorrect) {
accessGranted = true;
message = "Welcome to the admin panel!";
}
else {
accessGranted = false;
message = "Wrong password."
}
}
checkPassword(true)
console.log('Access Granted:', accessGranted);
console.log('Message:', message);

I am using await to pull data from the database. There's a variable secuity_ok that is true on one line, and then false on the next. Can anyone see what the issue is?
Note – if I comment out the line: let session = ..., then it all works.
Controller.prototype.changePassword = async function(request, response) {
let model = request.body;
var secuity_ok = false;
var user = await userService.getUserByEmail(model.email);
if (user && this.isAuthenticatedUser(request, user.id)) {
secuity_ok = true;
} else {
let session = await authenticationService.createSessionByEmailPassword(model.email, model.oldpassword),
secuity_ok = !!session;
console.log( 'A', secuity_ok ); // true
}
console.log( 'B', secuity_ok ); // false
if (!secuity_ok) {
this.sendForbiddenError(response, {
error: 'Cannot change password: Application safeguards are preventing this action'
});
return new Promise(() => {});
}
...
}
Output:
A true
B false
Output should be:
A true
B true

You have a comma at the end of the first line here:
let session = await authenticationService.createSessionByEmailPassword(model.email, model.oldpassword), // <--- Note comma here
secuity_ok = !!session;
That makes secuity_ok part of the let statement, so it's an extra, inner declaration of secuity_ok that only has scope inside the parentheses of the else clause.

Cannot read property 'result' of undefined
Angular Function :
.controller('forgotCtrl', function($scope,$http,$ionicPopup,$state,$ionicHistory) {
$scope.forgot=function(data1){
var link1 = 'http://localhost/uxo_data/forgot.php';
var json10 = {n : data1.mobile };
$http.post(link1, { data1: json10 })
.then(function (res){
$scope.response = res.data1.result;
console.log(res.data1.result);
if($scope.response.created=="1"){
$scope.title="Password Reset!";
$scope.template="Please Check your associated Email Account!";
//no back option
$ionicHistory.nextViewOptions({
disableAnimate: true,
disableBack: true
});
$state.go('login', {}, {location: "replace", reload: true});
}else if($scope.response.exists=="1"){
$scope.title="Failed";
$scope.template="Number you entered doesn't exist";
}else{
$scope.title="Failed";
$scope.template="Contact Our Technical Team";
}
var alertPopup = $ionicPopup.alert({
title: $scope.title,
template: $scope.template
});
});
}
})
Output i get from rest-api is :
{"result":{"created": "0" , "exists": "1" }}
I Checked in Web Debugging tool, php code is working fine and giving above response as output.

change this line from
$scope.response = res.data1.result;
to
$scope.response = res.data.result;
The response will have a data object which you are accessing incorrectly.

console.log(res.data1.result); // => data1 is undefined
try below code:
console.log(res.data.result);

Here's my code:
function guaranteedPost(endpointId, wallPost, attempts){
var attempts = attempts || 0
return graph.postAsync(endpointId + '/feed', wallPost)
.then(function(response){
return response
})
.catch(function(error){
if(error.message != errorMessage){
return Promise.reject(error.message)
}
console.log('Retry attempt #: ' + attempts)
if(attempts == 5){
return Promise.reject('Too many errors')
}
// console.log(error)
return Promise.delay(5000).then(function(){
return guaranteedPost(endpointId, wallPost, attempts + 1)
})
});
}
Everything works fine.
If I change the second if to an else if:
function guaranteedPost(endpointId, wallPost, attempts){
var attempts = attempts || 0
return graph.postAsync(endpointId + '/feed', wallPost)
.then(function(response){
return response
})
.catch(function(error){
if(error.message != errorMessage){
return Promise.reject(error.message)
}
console.log('Retry attempt #: ' + attempts)
else if(attempts == 5){ //BLOWS UP
return Promise.reject('Too many errors')
}
// console.log(error)
return Promise.delay(5000).then(function(){
return guaranteedPost(endpointId, wallPost, attempts + 1)
})
});
}
This blows up my code with a syntax error:
else if(attempts == 5){
^^^^
SyntaxError: Unexpected token else
Why is this happening? I am using else if statements all over my code and I receive no errors. Nothing I can seem to do in testing will allow me to get around this error.

It is because you have
console.log('Retry attempt #: ' + attempts)
before else keyword. else keyword is required to be immediately after if block.

You should get rid of this line from your code before else block
console.log('Retry attempt #: ' + attempts)
