How to fix this search filters for both upper case & lover case typing in Angular?












0















I found a search with filters Angular example here yesterday. Tried to make some changes on it and after that couldn't overcome these 2 challenges?




  1. When you type the name in lower case it doesn't give any result. It must completely match for working. While how can it be changed? So even if the user searches with lower case and types the correct name it finds the result? At the moment it requires uppercase as it provided in data.

  2. How can I implement autocomplete feature? So when a user types first characters it displays suggestions for that input?


Here is the code:



Pipe



import { Pipe, PipeTransform } from '@angular/core';


@Pipe({
name: 'filter',
})
export class FilterPipe implements PipeTransform {
transform(items: any, value: string): any {
if (!items) return ;
if (!value) return items;

return items.filter(singleItem =>
singleItem['name'].toLowerCase().includes(value.toLowerCase())
);

}
}


TypeScript



 import { Component, OnInit, Output, EventEmitter } from '@angular/core';
import { FormGroup, FormControl, FormBuilder } from '@angular/forms';

import { UserService } from '../user.service';


@Component({
selector: 'app-search',
templateUrl: './search.component.html'
})
export class SearchComponent implements OnInit {

form: FormGroup;

@Output() autoSearch: EventEmitter<string> = new EventEmitter<string>();
@Output() groupFilters: EventEmitter<any> = new EventEmitter<any>();

constructor(private fb: FormBuilder,
private userService: UserService) {}

ngOnInit(): void {
this.buildForm();
}

buildForm(): void {
this.form = this.fb.group({
name: new FormControl(''),
prefix: new FormControl(''),
position: new FormControl(''),
gender: new FormControl('')
});
}

search(filters: any): void {
Object.keys(filters).forEach(key => filters[key] === '' ? delete filters[key] : key);
this.groupFilters.emit(filters);
}

}


HTML



<h3>Group Filter</h3>
<div class="row">
<div class="col-md-3">
<input type="text"
formControlName="name"
class="form-control"
placeholder="name"
#searchText

</div>

<div class="col-md-3 col-sm-3">

</div>
</div>

          • Yes Of Course ! you can make the same technique they use in their library , you make a div under the input field and put all the items name on it and display the items that includes the user input

          • Their code is a bit confusing. I need autocomplete only for name input in the above example. They did something different with select.

            I think you will have to make a lot of work and wrap the name input with another component to display the names first and make a bind value with input event of name input and this component and apply the same pipe filter to it and also handle the enter event and click event when user did that I think ng-select make all of that for you already

          • Yes Of Course ! you can make the same technique they use in their library , you make a div under the input field and put all the items name on it and display the items that includes the user input

          • Their code is a bit confusing. I need autocomplete only for name input in the above example. They did something different with select.

            I think you will have to make a lot of work and wrap the name input with another component to display the names first and make a bind value with input event of name input and this component and apply the same pipe filter to it and also handle the enter event and click event when user did that I think ng-select make all of that for you already
