var xhr = cc.loader.getXMLHttpRequest();
xhr.responseType = “arraybuffer”;
xhr.addEventListener(“progress”, function (evt) {
if (evt.lengthComputable) {
var percentComplete = evt.loaded / evt.total;
console.log(“progress:” + percentComplete);
}
}, false);
我这边要从服务器下东西，在模拟器和安卓真机上报一个错误 Uncaught TypeError: xhr.addEventListener is not a function
