添加功能后，Greasemonkey 中的简单用户脚本不再工作
我刚刚开始使用 Greasemonkey，并尝试制作一个可以抓取页面的用户脚本 -
在开始之前，我尝试运行一些测试来提高我对 Greasemonkey 的熟悉程度（例如，我尝试了一个只有警报的用户脚本，有效）。但是，在我添加功能后，警报（在顶部调用）无法工作 - 为什么会发生这种情况？
//==UserScript==
'//@name stanfordWhoScraper
//@require http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js
//==/UserScript==
alert("TEST");
/*Functions*/
function jquerify(jquerified){
if(!(window.jQuery && window.jQuery.fn.jquery == '1.6.2')) {
var s = document.createElement('script');
s.setAttribute('src', 'http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js');
s.setAttribute('type', 'text/javascript');
document.getElementsByTagName('head')[0].appendChild(s);
jquerified = true;
return jquerified;
}
}
function findName(url){
if (!typeof url) return "Enter string url"
var name = $("#PublicProfile h2").load(url);
if (name == "") return "No name found";
return name;
}'
谢谢！
I've just started to use Greasemonkey and am trying to make a userscript that will scrape a page -
Before I got into that I tried running a few tests to increase my familiarity with Greasemonkey (for example I tried an userscript that had just an alert, which worked). However, after I added functions, the alert (which is called at the top), failed to work- why is this happening?
//==UserScript==
'//@name stanfordWhoScraper
//@require http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js
//==/UserScript==
alert("TEST");
/*Functions*/
function jquerify(jquerified){
if(!(window.jQuery && window.jQuery.fn.jquery == '1.6.2')) {
var s = document.createElement('script');
s.setAttribute('src', 'http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js');
s.setAttribute('type', 'text/javascript');
document.getElementsByTagName('head')[0].appendChild(s);
jquerified = true;
return jquerified;
}
}
function findName(url){
if (!typeof url) return "Enter string url"
var name = $("#PublicProfile h2").load(url);
if (name == "") return "No name found";
return name;
}'
Thanks!

该脚本存在多个问题。阻止它运行的两个因素是：
正如 Artyom 所说的流浪撇号。
将
'//@name stanfordWhoScraper更改为// @name stanfordWhoScraper并更改：
}'更改为}。格式错误的元数据块：
前导斜杠后需要空格。这是错误的并且失败了：
这是正确的：
There are multiple problems with that script. The 2 that keep it from running are:
Stray apostrophes as Artyom said.
Change:
'//@name stanfordWhoScraperto// @name stanfordWhoScraperandchange:
}'to}.Malformed metadata block:
Whitespace is required after the leading slashes. This is wrong and fails:
This is correct:
删除第 2 行上的单引号。它启动一个字符串，该字符串在遇到另一个单引号（在函数内部）时结束，因此不会进行解析。
Remove the single quote on line 2. It starts a string that ends when another single quote is encountered (inside your function), and therefore no parsing is made.
