Unable to load dynamic images on button click using Angular 6
0
I am loading 3 sets of dynamic images on a button click:
Before button click a default image has to be showed --> it is working as single image
On button click whatever images are there in the array based on the button id it has to load and display
Issues :
After clicking on data set one (i.e id : 1), based images have to load and overwrite the default image, but along with data set one image, the default image is also showing and 1st position image is missing.
Likewise whenever I click on the other button, the images are loading but it is displaying the previous image (last button last image) and also the 1st array index image is not displaying
The below is the default image before the button is clicked:
images =[
{
"img": "https://dummyimage.com/200x200/000/fff.jpg&text=a"
}
];
Buttons are generated using dynamic data:
buttonData = [
{
"id": 1,
"name":"Data Set One"
},
{
"id": 2,
"name":"Data Set Two"
},
{
"id": 3,
"name":"Data Set Three"
}
]
count: number;
currentImgUrl: string ;
constructor(){
this.count = 0;
this.setImgUrl();
}
next(): void {
this.count++;
if (this.count >= this.images.length)
this.count = 0;
this.setImgUrl();
}
prev(): void {
this.count--;
if (this.count < 0)
this.count = this.images.length - 1;
this.setImgUrl();
}
setImgUrl(): void {
this.currentImgUrl = this.images[this.count].img;
}
getImageData(id){
this.images=;
if(id===1){
this.count =0;
this.images = [
{
"img":"https://dummyimage.com/200x200/000/fff.jpg&text=B"
},
{
"img":"https://dummyimage.com/200x200/000/fff.jpg&text=C"

},
{
"img":"https://dummyimage.com/200x200/000/fff.jpg&text=F"
},
{
"img":"https://dummyimage.com/200x200/000/fff.jpg&text=G"
}
];
}
if(id===2){

I click the first button then hit next repeatedly. It displays B,C,D,E,F,G, click the second button and get H, I, J, hit the third button and get K,L,M. Those are exactly the images you've specified in the order you've specified them with none of them "missing". Explain?
