Question

JavaScript

I'm having trouble creating a pipe to look up values ​​across an entire table.

In my example, the filter only looks for one field. How to make a pipe to search for values ​​in the entire table?

Answer 1

Obviously, you need to iterate over all the fields, instead of checking for a specific one. For example like this :

class FilterPipe implements PipeTransform {
  transform(items: any[], term): any {
    const keys = items.length ? Object.keys(items[0]) : null;

    return term && keys
      ? items.filter(item => keys.some(key => item[key].toString().indexOf(term) !== -1))
      : items;
  }
}
