javascript - JS 编码不能在一个以上的页面上工作

转载作者：太空宇宙更新时间：2023-11-03 19:27:46

我是这方面的新手，已经能够让我的代码在我的第一页上运行，但不能在任何其他页面上运行。我试图将它作为导出的 js 文件来做，但它不起作用，所以我将它作为 a 添加到我的 html 页面的底部。现在它只是在那个页面上不起作用!所以这个有效:

 <p> In the afternoon we went to a different building to be part of the international group meet up. Firstly, we looked at and discussed a powerpoint led by Lance about SOS and how to improve the Discovery software and services in front of the CEO, Bill Goodwyn. While in the room we had to introduce ourselves; say our name, where we worked, discuss our school community and/or how we use Discovery software in our school. Except I didn't. I stayed quiet, sat back in my chair and took in everything everyone else was saying, listened and just did not introduce myself; because I don't enjoy big groups. Thankfully, Christine let me get away with this, saved me the embarrassment and let me stay in my comfort zone. </p>

During the DEN at Night I made friends with an awesome group of people, including Kelli, Heather and Kamala. These are my newest life-long friends.:)</p>
