Detailed explanation of bootstrap-validator usage (code example)

The required js, css and img are explained below, please read patiently!
Required js files: jquery.min.js, bootstrapValidator.min.js, bootstrap-validator-default.js (a customized default configuration file , written by an individual, unofficial file )
The first two files are available on the cdn. The content of bootstrap-validator-default.js is as follows:
