一个基于业务场景的工具方法库

function dataURLToBlob(data) {
    var parts = data.split(',');
    var meta = parts[0].substring(5).split(';');
    var type = meta[0];
    var decoder = meta.indexOf('base64') !== -1 ? atob : decodeURIComponent;
    var bstr = decoder(parts[1]);
    var n = bstr.length;
    var u8arr = new Uint8Array(n);
    while (n--) {
        u8arr[n] = bstr.charCodeAt(n);
    }
    return new Blob([u8arr], { type: type });
}
