How do I filter using user selected value with Angular Material Select?












0















I am trying to create a dropdown filter in angular material. Here is the array for my dropdown options



 public intensities = ['All',1,2,3,4,5]


Here is the html for the mat-select field.



    <mat-form-field>
<mat-select placeholder="Choose Intensity" [(ngModel)]="selectedIntensity" (selectionChange)="onIntensityChange()">
<mat-option *ngFor="let intensity of intensities" [value]="intensity">
{{intensity}}
</mat-option>
</mat-select>
</mat-form-field>

<div class="flex-wrap" style="display: inline-block; padding: 5px 0 5px 20px;">
<span style="font-weight:bold;">Show Shoppers With: </span>
<input style="margin-left: 10px; margin-right: 5px;" type="checkbox" [(ngModel)]="hiddenWithoutPhone" (change)="filterVisibleShoppers()">Phone
<input style="margin-left: 10px; margin-right: 5px;" type="checkbox" [(ngModel)]="hiddenWithoutEmail" (change)="filterVisibleShoppers()">Email
<input style="margin-left: 10px; margin-right: 5px;" type="checkbox" [(ngModel)]="hiddenWithoutAddress" (change)="filterVisibleShoppers()">Address
<input style="margin-left: 10px; margin-right: 5px;" type="checkbox" [(ngModel)]="hiddenWithoutTradeIn" (change)="filterVisibleShoppers()">Trade In
</div>


I am trying to write a function 'onIntensityChange()' that displays the correct choices based on the user selection. I also have a filter that works with a checkbox. I'd like to be able to filter based on both selections(dropdown and checkbox) Here is the typescript file.



   @Component({
templateUrl: 'daily-active-shopper.screen.html',
})

export class DailyActiveShoppersScreen {

public selectedDate: Date;
public maxDate: Date = new Date();
public count = 0;
public customers;
public loading: boolean;

public hiddenWithoutEmail: boolean;
public hiddenWithoutPhone: boolean;
public hiddenWithoutAddress: boolean;
public hiddenWithoutTradeIn: boolean;

_dealerId: number;

activeShopperDay: DailyActiveShopperDay;
visibleActiveShoppers: DailyActiveShopper;

shopperDetailsVisible = true;
shopperErrorMessage: string;

public intensities = ['All',1,2,3,4,5]
public selectedIntensity: any;

filterVisibleShoppers() {
let shoppers = this.activeShopperDay.shoppers;
if (this.hiddenWithoutAddress) {
shoppers = shoppers.filter((shopper) => {
return shopper.state !== null;
});
}
if (this.hiddenWithoutPhone) {
shoppers = shoppers.filter((shopper) => {
return shopper.phone !== null;
});
}
if (this.hiddenWithoutEmail) {
shoppers = shoppers.filter((shopper) => {
return shopper.email !== null;
});
}
if (this.hiddenWithoutTradeIn) {
shoppers = shoppers.filter((shopper) => {
return shopper.currentVehicle;
});
}
this.visibleActiveShoppers = shoppers;
}

onIntensityChange() {
console.log(this.selectedIntensity);
let shoppers = this.activeShopperDay.shoppers;
if(this.selectedIntensity === 'All') {
shoppers = shoppers.filter((shopper) => {
return this.visibleActiveShoppers = shoppers;
})
}
if(this.selectedIntensity === 1) {
shoppers = shoppers.filter((shopper) => {
return shopper.intensity === this.selectedIntensity
})
}
if(this.selectedIntensity === 2) {
shoppers = shoppers.filter((shopper) => {
return shopper.intensity === this.selectedIntensity
})
}
if(this.selectedIntensity === 3) {
shoppers = shoppers.filter((shopper) => {
return shopper.intensity === this.selectedIntensity
})
}
if(this.selectedIntensity === 4) {
shoppers = shoppers.filter((shopper) => {
return shopper.intensity === this.selectedIntensity
})
}
if(this.selectedIntensity === 5) {
shoppers = shoppers.filter((shopper) => {
return shopper.intensity === this.selectedIntensity
})
}

if(this.visibleActiveShoppers.length < 1) {
console.log("None found for this intensity")
}
this.visibleActiveShoppers = shoppers;
}


I'm looking for a proper way to implement this. Basically allowing the user to filter based on intensity and the four radio buttons.
