解决:创建XHR对象读取
function getText(){ // read text from URL location var request = new XMLHttpRequest(); request.open('GET', 'http://www.puzzlers.org/pub/wordlists/pocket.txt', true); request.send(null); request.onreadystatechange = function () { if (request.readyState === 4 && request.status === 200) { var type = request.getResponseHeader('Content-Type'); if (type.indexOf("text") !== 1) { return request.responseText; } } } }
⚠️ 是异步获取到的,可以包裹在 Promise 中
此方法可以用于在URL中读取文件内容
