JavaScript Line code, easy to handle floating Express message-v2 upgrade version _javascript tips

The day before yesterday I made a piece of paper [a line of code easy to handle the express message function], At the same time the release of the V1.0beta version of the Quick Message function and source code, the reason is beta, is the feeling although the basic skills can have, but not perfect, the characteristics are not necessarily reasonable, today unknowingly got to this time, the last version made a great improvement:
First of all, the original automatically submitted message information at the same time will automatically recommend, a large number of recommendations, directly affect the blog park recommended ranking mechanism, so later in the first time to change to ask whether to recommend the interactive mode!
Second, although the quick function has, and very good, but full screen of "good stickers!" I'll do you! "There is indeed some aesthetic fatigue, and there is no practical significance, the message or to be able to produce interactive only value, so V2 this version of the focus on interactive mode to improve the original form, the new version of the message is equivalent to the original Blog Park message box and recommended are floating up to show the right side of the screen vertically centered position, The goal is to make it easy for users to express messages.
Finally, the new version of the Quick Message function for the previous version of the user fully support the transparent upgrade, that is, the original use of the previous version of the users, now their blog to see should already be the latest version of the interface and features! Let's go over it again. The use of jmsg is exactly the same as before:
In fact, the usage is really very simple, only in the [admin]->[set]->[page first HTML code] text box, fill in the following sentence on the line:

Copy Code code as follows:

In a text box [background admin]->[set]->[page first HTML code]
<script language= "javascript" type= "Text/javascript" src= "Http://files.cnblogs.com/justinw/jMsg.js" ></ Script>

As shown in the following illustration:

The new version jmsg specific function details, the above figure has been described in detail, is not tired, the following is a new version of the source code, there are many functional features to be perfected, such as the interface effect can be beautified, now only provides the most minimalist style, whether it is code or functional design, are welcome to criticize correct. The organization of the Code as compared to the previous version has changed a lot, the last version of the source code here can be obtained.
The new source code is as follows:

Copy Code code as follows:

Finding DOM elements by classname
