Jquery 与 Tampermonkey

Question

所以我的控制台给了我这条消息 -

    The page at https://en.wikibooks.org/wiki/Vehicle_Identification_Numbers_(VIN_codes)/GM/VIN_Codes ran insecure content from http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js.
jquerified: true
ERROR: Execution of script 'GMVinCodeScraper' failed! $ is not defined
ReferenceError: $ is not defined

    at W (eval at eventHandler (eval at <anonymous> (chrome-extension://dhdgffkkebhmkfjojejmpbldmpobfkfo/content.js:57:21)))

在我的用户脚本中，我正在运行一个自动在页面上包含 jquery 的函数，并且似乎 jquery 已加载，因为我可以看到一个带有 jquery url 作为 src 属性的脚本标记。

作为引用，该函数在这里 -

function jquerify(jquerified){
if(!(window.JQuery && window.Jquery.fn.jquery == '1')){
    var s = document.createElement('script');
    s.setAttribute('src','http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js');
    s.setAttribute('type','text/javascript');
    document.getElementsByTagName('head')[0].appendChild(s);
    jquerified = true;
    console.log("jquerified: " + jquerified);
    return jquerified; 
}
}
jquerify(false);

所以，不确定为什么 $ 不会被定义。知道为什么吗？

更新-

使用@require解决了这个问题。

Answer 1

您可以使用@require url 来解决这个问题

// @require https://ajax.googleapis.com/ajax/libs/jquery/3.4.0/jquery.min.js
