Question

我使用了这段代码并且工作正常，但我无法初始化旋转按钮。有人帮忙吗？当我尝试创建按钮并添加代码时

$('.upload-rotate').on('click', function(ev) {
            uploadCrop.rotate(parseInt($(this).data('deg')));
        });

它赢得了旋转图像并且它表示存在函数旋转doesent。有人可以帮忙吗？

<?php
    if(isset($_POST['imagebase64'])){
        $data = $_POST['imagebase64'];

        list($type, $data) = explode(';', $data);
        list(, $data)      = explode(',', $data);
        $data = base64_decode($data);

        file_put_contents('image64.png', $data);
    }
?>
