Utilizing Typescript to extract data from a database according to the input provided by the user

Trying to fetch data from Database based on user input. Below is a snapshot of the DB for reference.

https://i.sstatic.net/iMRup.png

In my frontend, I have a dropdown that displays names from the database. Upon selection, I need to retrieve the corresponding folder based on the category chosen by the user. Here's what I've attempted in typescript:

    loadResourceCategory() {
      this.categories = new Array<ResourceCategory>();
      this.isLoading = true;

      return this.resourceService.getResources()
        .then((categories: Array<ResourceCategory>) => {
          this.categories = categories;
          this.categories.forEach((category: any) => {
            category.details = `${category.Name}`;
            this.selectedCategory = category.Id;

            if (category.Id === this.selectedCategory) {
              this.foldername = category.Folder;
              console.log('Selected Category folder is :', + this.foldername);
            }
          });
        })
        .catch(() => {
          this.modalService.error('Resources cannot be loaded now, Please retry later');
        })
        .finally(() => {
          this.isLoading = false;
        });
    }

Currently, I'm able to retrieve the ID of the selected name but unable to fetch the corresponding Folder information. Any suggestions on how to resolve this issue? Your help is much appreciated!

Answer №1

Success! By simply removing the "+" sign, I was able to fix the problem. console.log('The selected folder category is :', + this.foldername);
