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:
/*默认规则 start*///ip格式$.fn.bootstrapValidator.validators.ip = { //message: "ip格式不正确"
