I want to check is checkbox is checked or unchecked in an if and else statement.
<md-checkbox id="mon" (change)="mon($event)" [checked]="true">Checked</md-checkbox>
mon(e){
if(e.target.checked){
console.log("This is checked")
} else {
console.log("unchecked");
}
}
I think I am doing it really wrong. I keep getting can't get checked of undefined. How is the way to do this?
declare a variable called it filter
filter: boolean= false;
then use ngModel in html part to access and assign its value.
<input type="checkbox" [(ngModel)]="filter" (click)="filterData()">
it will call a function filterData() which you can use to do all your functionality
filter(){
this.filter = !this.filter;// this will change value of it true and false
}
for more checkbox you can use declare more variable like filter1: boolean
