Question

Activate the paste option in input files by using the right mouse button

I have created a file input in my Angular application that can detect image pasting using CTRL-V. Is there a way to enable the paste option when I right click on the input?

Any assistance would be greatly appreciated!

Here's the code snippet:

@HostListener("paste", ["$event"])

  onPaste(e: ClipboardEvent) {
    let clipboardData = e.clipboardData || (window as any).clipboardData;
    let pastedData = clipboardData.getData("text");
    if (pastedData.includes("data:image")) {
      var binary = atob(pastedData.split(",")[1]);
      var array = [];
      for (var i = 0; i < binary.length; i++) {
        array.push(binary.charCodeAt(i));
      }
      var pasteImages = new Blob([new Uint8Array(array)], {
        type: "image/jpeg"
      });
    } else {
      alert("Select an image in the correct format");
    }
  }

Answer №1

Consider implementing the following code snippet right below your existing HostListener:

@HostListener("mousedown", ["$event"])
onMouseDown(event) {
  if (event.button === 2) {
    event.target.contentEditable = true;
  }
  // wait for 'contextmenu' to trigger
  setTimeout(() => (event.target.contentEditable = false), 20);
}

Additionally, by eliminating the type=file attribute from the input, the context menu will be able to display:

<input id="files" multiple (change)="detectFiles($event)" accept="image/*">
