JavaScript can easily implement the quick message function with just one line of code

Don't worry, the method is very simple, let me talk about its origin first...

In the beginning, the function of quick message can be traced back to the publication [Complete Analysis of AjaxControlToolkitTests Automatic Testing Framework Part 1: Architecture] When I wrote this article, it was purely a by-product of that article. I didn’t pay much attention to it at first. I thought it was just a shortcut for lazy people like me. Later, because there was no prompt, this function would automatically submit the message directly. This aroused the dissatisfaction of several classmates, so later a reminder was added in a prominent position: [Tip: The shortcut link will directly recommend and submit message information. ], the situation was calmed down;

Later, some students may have too advanced mouse and fast combo speed. Every time they use my quick message function, they will put five (I want to like, Passing by, looking forward to the next article, it’s great, I want to recommend it) Click all the shortcut links to enjoy it. Originally, I put so many shortcut links in the hope of providing you with more choices. My intention is that I don’t want you to have every Clicking them all, it turns out that it was originally a lazy tool for lazy people, but it suddenly made people become hardworking. It is really a sin. I can’t stand it when everyone is so hard-working. The comments are like a chat room that’s being flooded with messages. The fundamental reason is that the original program was written too simply without considering the details, so now only two shortcut links are left, and Limitations have been added to the program so that the screen will not be refreshed.

Later, in the past few days, I found that more and more people have added the quick message function to their blogs. When I saw this article (here) yesterday, it was almost intact. Dibaibox copied the code of my quick message function. These applications make me rethink the positioning of the small function of quick message. Objectively speaking, this function is actually a good extension of the existing message function of the blog park! So, instead of letting people reinvent the wheel repeatedly, why not provide a public extension for everyone to use directly?
Based on the above historical reasons, after several hours of hard work, a new version of the universal quick message function was born! The goal of this version is to be simple and universal. Bloggers in other blog parks can directly add the quick message function to their blogs by simply citing it! At present, this function is set to v1.0bate version, and there are still some features to be improved. Future versions will provide more user-defined setting functions, and any new ideas will be gradually added, so if you want to be able to automatically upgrade to new ones in the future, version, just quote my file directly, and all users who use this script will be updated simultaneously.
In fact, the usage is really simple. You only need to fill in the following sentence in the text box of [Backstage Management]->[Settings]->[Top HTML Code].

Copy code The code is as follows:

 
//Place it in [Backend Management]->[ Settings]->In the text box of [Header Html code]

Your criticisms and corrections are welcome! The code is very simple, and I have added a lot of comments, so I won’t go into details here. If you have any questions, just leave a message.
