and here is my method to switch between images in ts file

export class StdntprofilePage {
imgpath:string;
.................................



 constructor(){
 togglepic()
}
 togglepic(){

    if(this.gender=="boy")
    { 
       this.imgpath="./assets/img/userboy.png";
    }
    
    else(this.gender=="girl")
    {
       this.gender="./assets/img/usergirl.png";
    }
  }



}

but each and every time im getting userboy picture.

I’m surprised this even compiled.

if () {
}
else () {
}

does not look like syntactically valid JavaScript to me. I’m also confused by the naming of the function togglepic. I would expect a function called that to switch the picture from one of two states to the other, and if I called it twice it would undo itself. I would call it something like avatarFromGender() instead.

Look the else. You need store url on imgpath variable, not gender variable.

You need to show us the latest code you are using. Basically you’ve two errors in your code, one is a syntax error and the other logical.

This has syntax error as hinted by @rapropos. It should be else if (this.gender=="girl")

This has the logical error as pointed out by @rtalexk. It should be this.imgpath = "./assets/img/usergirl.png";

There is also the issue of what happens if gender is neither boy nor girl, and I suppose it could be considered poetic that this code silently gives such people no avatar at all.
