我正在尝试使用jQuery,它给了我各种错误。我尝试过洗牌不同的脚本标签,但没有成功。这里是一些代码:为什么jQuery不能使用Bootstrap 4 alpha 6?

$(".welcomeSize").fadeIn(500);

我得到一个错误,说jQuery是未定义的。如果我把我的脚本之前的jQuery CDN,我得到这个错误:
Uncaught TypeError: a.indexOf is not a function
at r.fn.init.r.fn.load (jquery.min.js:4)
at newsite.html:129
有什么我失踪?
删除bootstrap。你会很快看到它是不相关的。 –
