嗨:
有人可以向我解释一下为什么jQuery
没有定义?
它是 vendor.js
的一部分文件(webpack),并在 vendor.js
中被提及数百次,如* jQuery JavaScript Library v2.2.4
所以它肯定已加载。
为什么 jquery-ui 看不到它是没有意义的,但我在 Angular 2 上已经经历了好几个星期的垃圾了。在过去(1 个月前),你要确保在其余部分之前加载一个文件,然后您已被排序。
当然,如果包含“实际”,我可以让 2 个依赖项(UI 和 jasny)运行 <script>hardrive/bla/jquery.js
在 _Layout.shtml
,但是如果 webpack 也将其包含在 vendor 文件中,那还有什么意义呢?
所有这些都是一个更大问题的一部分,让一个简单的旧东西
.animation = $({
countNum: from
})
运行,我已经运行了两周了,它已经在 angularjs 中运行了。 WebPack 文件:

最佳答案
在Webpack配置中已经使用了jquery Provideplugin,如果没有使用这个
new webpack.ProvidePlugin({
$: "jquery",
jQuery: "jquery"
})
关于javascript - Angular/webpack 站点中未定义 jQuery,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/42919079/
