Using input type file with angular material 2

How can I use angular material 2 FAB button to open the browse input dialog? It can be done in HTML this way.

<button type="button">
    <label for="file-input">click</label>
</button>
<input type="file" id="file-input" style="display:none">

I tried the same approach with material 2, but it doesn't work.

<button md-mini-fab type="button">
    <label for="fileToUpload">
        <md-icon>add</md-icon>
    </label>
</button>
<input id="fileToUpload" type="file" style="display:none;">

Are there any other ways that would work? Thank.

You just need to call click

to input your file.



<button md-mini-fab type="button" onclick="document.getElementById('fileToUpload').click()">
  <label for="fileToUpload"><md-icon>add</md-icon></label>
</button>
<input id="fileToUpload" type="file" style="display:none;">

Here's a simple solution:



<button (click)="fileInput.click()">
  <md-icon>library_add</md-icon>
  <span>Select</span>
  <input #fileInput type="file" (change)="onFileInput($event)" style="display:none;" />
</button>

Try it:

<input #file type="file" [hidden]="true" accept="image/*" (change)="upload(file.files)">
<button mat-button #upload (click)="file.click()">Upload file</button>

<mat-button>

from https://material.angular.io

We hide the main input button and bind the material button to the file upload.

I'm not sure about your cases, but in my Angular5 app I used this HTML structure to upload files to the server:

<label for="uploadPicture" class="upload-file">
   <mat-icon>add_a_photo</mat-icon>
</label>
<input type="file"
       id="uploadPicture"
       class="hidden-input"
       accept="image/jpeg, .jpeg, image/png, .png, image/pjpeg, .jpg"
       (change)="selectFile($event.target.files[0])">

This solution works fine in my case. No need to trigger the event click

because when you click on <label>

which is associated with input

it is similar click

to input

.

It can be a combination of md-button, md-dialog and md-input. The mini fab button must have a click event to trigger the md-dialog component.

<button md-mini-fab type="button" (click)="openDialog()">
    <label for="fileToUpload">
      <md-icon>add</md-icon>
    </label>
</button>

Inside the md-dialog component, you can add an md-input field.

<h1 md-dialog-title>Dialog</h1>
<div md-dialog-actions>
  <md-input-container>
    <input mdInput id="fileToUpload" type="file">
  </md-input-container>
  <p>
    <button md-button (click)="dialogRef.close('Option 1')">Option 1</button>
    <button md-button (click)="dialogRef.close('Option 2')">Option 2</button>
  </p>
</div>

You can use the button and enter. Make sure this button does not cover the input .

<button (click)="fileInput.click()">Upload</button>
<input #fileInput type="file" (change)="onFileInput($event)" multiple style="display:none;" />

You can also use a label containing the input.

<label>
    <mat-icon>add</mat-icon>
    <input type="file" (change)="onFileInput($event)" multiple />
</label>
