How to set the main function of java-javaTutorial-php.cn

The following are the main control functions and some public methods. Including throwing exceptions and logging. Expand, traverse. Set method model path. Get the model (must be set before you can get it, otherwise an exception will be thrown) to judge (data).

Introduce this file first when using it. Then you need to set it up like this

alfred.setMethod("basic.js",["alfred","alfred.global","alfred.doc","alfred.reset","alfred.log","alfred.isNumber",  "alfred.isFunction","alfred.isArray","alfred.isObject","alfred.isString","alfred.isBoolean",  "alfred.require","alfred.setMethod","alfred.extend"],[]);

After setting it up, you can tell the following JS that I have provided these methods. Just type alfred.require("alfred.reset"); to pull the file into the page and register it.

This is what the page looks like.

<!DOCTYPE html> <html> <head> <title> </title> </head> <body> <script type="text/javascript" src="base.js"></script> <script type="text/javascript" src="deps.js"></script> <script type="text/javascript"> alfred.reset("$");  $.require("alfred.dom");  $(function(){  vara = $.dom("<div id=&#39;test&#39; style=&#39;width:200px;height:200px;background:red;&#39;> adf</div>");  $.dom("body").prepend(a);  })  </script> </body> </html>

alfred.reset is for the convenience of setting the method name. In this way we can use it almost like jquery.

alfred.reset("$");

$.require("alfred.dom");

$.dom("div a span:first-child ").append("hello alfred");

can be used like this.
