The final result is displayed:
Needless to say, the code is marked with detailed comments.
However, during the test, I encountered one or two problems. First, the encoding format of the XML file must be a UTF-8, that is, to ensure that <? Xml version = "1.0" encoding = "UTF-8"?>, Otherwise, garbled characters may occur. Because jQuery's Ajax transmits data using UTF-8 encoding.
Second, it is about the encoding of JS files. In principle, Chinese characters should not appear in JS files. In the test, I added a test for Chinese characters, such as code snippet $ ("# Message_error "). text ("Error loading XML document (XML file loading Error)" + xml); indicates the Error message prompt when the XML file cannot be correctly parsed or cannot be found, during the test, we found that the Chinese characters "loading XML file errors" were garbled. After a long time, I realized that the JS file encoding was a problem. I checked it online for a long time, and no one explicitly explained the solution. Even if there was one, it did not solve the problem of Garbled text, in addition, most people are talking nonsense. If a post is transferred in and out, it will be harmful if it has never been tested. Finally, I figured out how long it was, and finally solved the problem of the JS file layout. I also fixed the issue of garbled characters when the jquery.html () function and the jQuery. text () function were transmitting Chinese characters.
Solve the Problem of garbled characters when the jquery.html () function and jQuery. text () function are transmitting Chinese characters. Please refer to another article titled Code Conversion of JS files.
