My Campus My Home Project
It has been a few days since the defense of the project, and I will summarize what I have obtained in this project, so that I can review it later:
The first is to modify the password function:

The above is the record of changing the password, which is convenient for reference in the future
docs in docs and can be edited on this
<iframe src="071.jsp" width="100%" height="1500px"
style="border: medium none;z-index : -1;position: absolute;border: 0;">
</iframe>
It is very convenient to use iframe to introduce the content of other pages. For my project, the biggest convenience is to introduce page special effects#
Share a nice particle effect

The gif animation used in the project
All pictures come from the Internet;
if there is any infringement, it can be deleted immediately;
Learned how to create the map you want
http://api.map.baidu.com/lbsapi/creatmap/index.htmlBaidu Map Generator
You can fill in the address you want to generate code and copy it to jsp to use.
I also use iframe application in the project
The above is what I want to share, for reference only
