When the imagepath in an Angular application is not updated, it will revert to null

Below is the code snippet that I am currently working on:

<div class="col-sm-4 pl-5">
  <img attr.src="{{item?.imagePath}}"  required height="200" width="200">
</div>

In my TypeScript file (ts), I have the following function:

editBlog() {
console.log(this.teamForm.value)
const BlogPost =     {

  "firstName": this.teamForm.value.firstName,
  "lastName": this.teamForm.value.lastName,
  "description": this.teamForm.value.description,
  "designation": this.teamForm.value.designation,
  "imagePath": this.teamForm.controls['imagePath'].value,
  "status": "status",
  "active": true,
  "employmentType": {
      "id": this.type,
      // "employmentTypeName": "Full-Time"
  }
}
console.log(BlogPost)
console.log('hftttttt',this.teamForm.value.imagePath)
// console.log(this.id,this.item,this.employmentType)
if(window.confirm('Are you sure you want to update?')){
const jsonData= BlogPost;
if(this.file['name']){}
const formData = new FormData()
formData.append('file', this.file , this.file['name']); 
formData.append('jsonData', JSON.stringify(jsonData));
this.team.editTeam(this.id,formData).subscribe((response)=> {
  this.router.navigate(['/home/team'])
  console.log(response);
});

I am facing an issue where an empty(null) call is made to the API when the image is not updated. Can someone help me figure out how to prevent this and also how to retain the old imagePath if no other values are being updated in the element?

Answer №1

To reference the image path in a TypeScript file, you can directly use the HTML tag ID.

Here is an example of how to accomplish this:

"imagePath": (<HTMLInputElement>document.getElementById("imagePath")).src),

Additionally, in your HTML code, you can include the image element with the specified attributes:

<img attr.src="{{item?.imagePath}}" id="imagePath" required height="200" width="200">
