JS实现文件转base64

 

核心：

function file2base64(){
    fileAddress = document.getElementById("fileImage").files[0];

    file = new FileReader();
    file.readAsDataURL(fileAddress);
    file.onload = function(){console.log(file.result);}
}

 

 

完整代码：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
</head>
<body>
    <input type="file" name="" id="fileImage">
    <button onclick="file2base64()">文件转base64</button>
    <script>
        function file2base64(){
            fileAddress = document.getElementById("fileImage").files[0];

            file = new FileReader();
            file.readAsDataURL(fileAddress);
            file.onload = function(){console.log(file.result);}
        }
    </script>
</body>
</html>
