Can anyone lend a hand? I'm facing a challenge with this function that is crucial for the application.
Typescript File
get $approved(): Observable<boolean> {
return this.$entries.map(entries => {
if (entries.length > 0) {
return false;
} else {
entries.every(entry => {
return entry.approved != null;
})
}
});
}
HTML file
<h1 *ngIf="$approved | async">PLANT</h1>
The issue here is that the H1 tag never gets displayed, and I'm unsure why.
Your else statement does not have a return value, causing the method to only output either false or undefined, both of which are falsy values. To fix this issue, update your code to return the result of the every function:
return entries.every(entry => {
return entry.approved != null;
});
The value is never actually returned in the given code when it is true. In the else statement, you probably intend to have:
return entries.every(entry => {
return entry.approved != null;
});
The value is not being returned correctly in this instance:
entries.every(entry =>{ return entry.approved != null; })
You might want to consider implementing something along these lines instead:
let result = false;
entries.every(entry =>{
if (!result) result = (entry.approved != null) ? entry.approved : false;
});
return result;
A return statement within a callback function does not automatically become the overall return value for the outer function. Closures do not apply to return values. The outer function must explicitly use a return statement.
