措手不及:Bootstrap的JavaScript需要jQuery [英] Uncaught: Bootstrap's JavaScript requires jQuery

问题描述

我在页脚部分包含了jquery和bootstrap.min.js文件，或者这意味着我的所有脚本标签都位于代码底部.但是，当我加载页面时，浏览器控制台抛出错误:未捕获的错误:Bootstrap的JavaScript需要jQuery. 我在本地包含这些文件，如下所示:-

I have included jquery and bootstrap.min.js file in my footer section or it means i have my all script tag at the bottom of the code. But when i am loading my page the browser console throw an error says : Uncaught Error: Bootstrap's JavaScript requires jQuery. I am including these files locally like below:-

</footer>
<script src="http://127.0.0.1/ems_ci/assets/js/jquery.js" type="text/javascript"></script>
<script src="http://127.0.0.1/ems_ci/assets/js/bootstrap.min.js" type="text/javascript"></script>
</body>
</html>

推荐答案

使用localhost或127.0.0.1作为文件路径并不常见.改为使用relative path.

It's uncommon to use localhost or 127.0.0.1 for a file path. Use relative path instead.

关于脚本位置:您可以将它们保留在页脚中，这将加快页面加载速度，但请确保在dom中jquery/bootstrap之后执行的任何JavaScript代码. 并且不要忘记将代码包装在document ready jquery函数

Regarding script position: you can leave them in the footer, that will speed up page loading, but make sure any JavaScript code you execute is AFTER jquery/bootstrap in the dom. And don't forget to wrap your code inside a document ready jquery function
