Angular base 64符号化
この原理はとても简単で、しかし私は长い间/颜を覆って、ついに成功して、记录してhtml
ts/js
<input type="file" id="file">
<input type="submit" (click)="turnToBase64()">
ts/js
turnToBase64() {
const getfile = document.getElementById('file') as HTMLInputElement;
console.log(getfile);
const reader = new FileReader();
reader.readAsDataURL(getfile.files[0]);
reader.onload = () => {
console.log(reader.result as string);
};
}
