将HTML插入文档正文挂起

I'm trying to insert HTML into the body of a web page using NightmareJS. I'm using the following code to work within the document scope:

我正在尝试使用NightmareJS将HTML插入到网页正文中。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");

The console.log never happens. Instead I get:

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)

If I remove the innerHTML line, it executes fine and I can return values from matchResult. What's wrong here?

如果我删除innerHTML行，它执行正常，我可以从matchResult返回值。这有什么不对？

It looks like you need to createElement('a'), define the text, then add the link only with innerHTML. There's a similar question here: make hyperlink from javascript , assuming that you want to create a new element.

看起来你需要createElement（'a'），定义文本，然后只用innerHTML添加链接。这里有一个类似的问题：从javascript创建超链接，假设您要创建一个新元素。
