Question

我试图在此下载脚本中包含两个函数，但我无法使其工作

1-在下载结束时（动画下载栏），在示例浏览器中自动开始下载：window.open ()。但这包括脚本中的默认名称。

2-当检测到死链接或大小为0字节时，如果可能，request.open ()会发出警告。

任何帮助都非常有用，问候。

var _OBJECT_URL;


document.querySelector('#download-button').addEventListener('click', function() {
	var request = new XMLHttpRequest();
    request.addEventListener('readystatechange', function(e) {

    		document.querySelector('#start-download').style.display = 'block';
    		document.querySelector('#download-button').style.display = 'none';

// HERE NOTICE DEAD LINK

//If the link is dead, notify with some notice
