想通过转换成Base64var reader = new FileReader();
reader.readAsDataURL(Bolo); //这个位置要传Bolo 对象reader.onload = function(e){ console.log(e.target.result);
}MDN 有这种方式但不知道怎么补全var oReq = new XMLHttpRequest();
oReq.open("GET", "/myfile.png", true);
oReq.responseType = "arraybuffer";
oReq.onload = function (oEvent) { var arrayBuffer = oReq.response; // Note: not oReq.responseText
if (arrayBuffer) { var byteArray = new Uint8Array(arrayBuffer); for (var i = 0; i < byteArray.byteLength; i++) { // do something with each byte in the array
}
}
};
oReq.send(null);http://runjs.cn/detail/4kmutrhc
