In Angular, I use a simple function that return a Promise and in 'then' function I change src of an Img html tag. when I call this function from NgOnInit (or from onclick), html will not update until i force the content to reload by another click on something. but colsole.log work.
click1() {
this.loadCaptcha();
}
ngOnInit(): void {
this.loadCaptcha();
}
loadCaptcha() {
this.apiService.getCaptcha()
.then((data) => {
this.image = 'http://....' + data.id;
console.log(data);
});
}
<img [src]='image' (click)="click1()" />
I solve that, the problem is a line of code that exists in Metronic template that disabled data binding. by disabling changeDetection modification, binding worked again.
changeDetection: ChangeDetectionStrategy.OnPush,
