Question

I want get the file name from my html input tag in a modal view and save it using Angular2. Can someone help me?

Answer 1

This work form me:

HTML

<input type="file" (change)="detectFiles($event)">
<div class="output">Seleccionado: {{ fileName }} </div>

TS

selectedFiles: FileList;
fileName: string;

detectFiles(event) {
    this.selectedFiles = event.target.files;
    this.fileName = this.selectedFiles[0].name;
    console.log('selectedFiles: ' + this.fileName );
  }

Answer 2

You can try a more elegant option:

HTML:

<input #file type="file" (change)="updateFile(file)">

Script:

updateFile(file: HTMLInputElement) {
  let name = file.value;
}

Answer 3

HTML

<button (click)="imgFileInput.click()">Add</button>
    {{ imgFileInput?.files[0]?.name }}
<input hidden type="file" #imgFileInput (change)="uploadSingle($event)"/>

Component

uploadSingle(event) {
  const fileName = event.target.files[0].name;
}

Answer 4

You can do next:

HTML:

<input type="file" (change)="fileEvent($event)" />

TypeScript:

fileEvent(fileInput: Event){
    let file = fileInput.target.files[0];
    let fileName = file.name;
}

Answer 5

HTML

<input type="file" (change)="onFileChange($event)">

Script

onFileChange(event) {    
     let files = event.target.files[0].name;
}

Answer 6

This link's https://stackoverflow.com/a/44932086/4281182 solution suggested by @ Selçuk Cihan did not help so my workaround was to make the fileInput param type "any" by doing this

fileEvent(fileInput){
    let file = fileInput.target.files[0];
    let fileName = file.name;
}

so in TS runtime this is a pure JS code

Anyways thanks for this great ans it saved me a lot of time
