javascript - 将HTML插入文档主体时挂起

Question

我正在尝试使用NightmareJS将HTML插入网页的正文中。我正在使用以下代码在文档范围内工作:

await nightmare.evaluate(function(users) {
        for(var i = 0; i < users.length; i++) {
            var matchResult = users[i].match(/.com\/(.*?)\?fref/);
            if (matchResult) {
                document.body.innerHTML += '<a href="https://www.example.com/'+matchResult[0]+'">'+matchResult[0]+'</a>';
            }
        }
    }, users);
console.log("we got here");

console.log永远不会发生。相反，我得到:

Error: Evaluation timed out after 30000msec.  Are you calling done() or resolving your promises?
    at Timeout._onTimeout (/home/user/www/project/bin/scraper/node_modules/nightmare/lib/actions.js:509:10)
    at ontimeout (timers.js:469:11)
    at tryOnTimeout (timers.js:304:5)
    at Timer.listOnTimeout (timers.js:264:5)

如果我删除 innerHTML行，它执行得很好，我可以从 matchResult返回值。怎么了

看起来您需要createElement('a')，定义文本，然后仅使用innerHTML添加链接。这里有一个类似的问题:make hyperlink from javascript，假设您要创建一个新元素。
