Launching the file explorer when the icon is clicked

I am currently working with Angular 5 using Typescript. I need assistance in opening the file explorer window to add an attachment when clicking on an icon. I have successfully done this for a button, but I am facing issues with the click event binding on the icon. Can someone please provide some guidance?

<input type="file" #file (change)="upload()"/>
<span class="icon-doc" (click)="file.click()">
</span>

Here is the code snippet from my component :

upload(){
    //This is where the code for uploading file(s) will go
}

Ensuring your code is implemented correctly is crucial. You must bind the icon to a click method so that it can programmatically trigger a click event on another input element responsible for file attachment. Here's an example of how you can achieve this:

<a (click)="handleClick()" href="javascript:undefined">
  <i class="la la-upload"></i>
</a>

<input class="hidden" type="file" id="upload-file" name="upload-file" accept=".csv" ngf-max-size="2MB" (change)="addAttachment($event)">

To hide the input button using CSS, you can style it as follows:

.hidden {
  visibility: hidden;
  width: 1px;
  height: 1px;
}

In your component.ts file, include the following:

handleClick() {
  document.getElementById('upload-file').click();
}

addAttachment(fileInput: any) {
  const fileReaded = fileInput.target.files[0];
  // Handle the remaining functionality here
}
