What is the best way to utilize this.http.post function multiple times?

Utilizing Angular10 and Typescript.

I want to avoid using 'window.location.reload()' when making multiple http.post requests in my application. Specifically, I am encountering an issue when trying to open a Dialog to edit the Parent's data.

dialog.afterClosed(){
    window.location.reload()};

The function behind the 'send button' is as follows:

async onOkClick() {
    var e = await this.groceryListCrudService.post(this.myData);
    this.dialogRef.close('Ok');
}

This is the post function being called:

post(item: Partial<PortFolio>) {
    return this.http.post<any>(this.url, item, this.httpOptions).subscribe({
        next: (data) => {
            this.post = data.id;
        },
        error: (error) => {
            console.error('There was an error!', error);
        },
    });
}

Upon clicking the button twice, even after waiting for the data to be inserted into the database, I encounter the following error:

ERROR Error: Uncaught (in promise): TypeError: this.groceryListCrudService.post is not a function TypeError: this.groceryListCrudService.post is not a function

If more code is needed for further assistance, please let me know. Thank you!

Answer №1

To replace the line this.post = data.id, make sure to utilize return data.id instead. It is not valid to directly assign a value within the function declaration.
