This question is not a duplicate of Uncaught ReferenceError: $ is not defined?
这个问题不是Uncaught ReferenceError: $ is not defined?
Because all the answer of that question suggest to put the references to the jquery scripts first, but it does not work for me.

<script>should not be self-closed, it'll not load the script. See Why don't self-closing script tags work?
<script>不应该自我关闭，它不会加载脚本。请参阅为什么自关闭脚本标签不起作用？
