Sighs at the core code of my jskit.

　　Tutorial on helping customers (www.bkjia.com)I started to write my JSKit for a long time and was never satisfied with it. In the meantime, I downloaded a large number of frameworks to check that their architecture and design did not find a satisfactory version. In the end, I still made continuous improvements. In fact, I have been reducing the core code to my satisfaction. only two public methods are encapsulated in the version result. One is Import (Loading Code) the other is Run ).

Why are I not satisfied with so many excellent and powerful frameworks on the Internet? Because my requirements for the framework are actually very simple, I only need it to manage and organize my code. It's OK. I don't need to load a bunch of data in my implementation when implementing a simple function. I hate this kind of waste of code that cannot be used in a function process, so I haven't found anything that I like for a long time.

As a program that has not been started for a long time, I have been pursuing simple logic code. So I am not familiar with some waste of time. I cannot understand some complicated logic for a long time, and I am writing it in the end. Looking back on the coding path over the years, we sadly found that we can only be at the entry level in our life and cannot reach a higher level of experts (teachers), because we have learned a lot, the energy is dispersed. If there is an afterlife, I think I will fight for a dark path.

In addition, let's talk about the following code. Because there are few codes, there is no comment to write. Just talk about the ideas.

Import method: load a class, which can be a very simple class or a framework. The idea of my organization management code is mainly implemented through the import method. For example, I created a com. the imcjj sub-folder contains a Browser. the js file passes JK. import ("com. imcjj/Browser ") import the Browser. the js File Code "JK" is an example of JSKit.

　　Call Demo:

Reference content is as follows: Var JK = new JSKit ("/jskit. src /"); If (JK ){ JK. Import ("com. imcjj/FormValidate "); JK. Import ("com. imcjj/Browser "); JK. Run (function (){ Var browser = new JK. Browser (); Alert (browser. name + "\ n" + browser. agent ); Var oFormValidate = new JK ["FormValidate"] ("frmDemo "); Var oObj = oFormValidate. _ form; If (! OObj) {alert ("no form is found and form verification cannot be performed"); document. close ();} Var oTip = new Tip (); OTip. _ struct = "<strong >{# text #}</strong> "; OTip. _ inertDirection = 0; OTip. add ("tip_Name", "tip_bottom", "custom message", oObj. elements ["Name"]. parentNode, "SPAN", "<strong >{# text #}</strong> "); // Add an external verification function // OFormValidate. addValidate ("isDate", fnCheckDate, "f", "is the date correct? "); // Parameter: verification method. The ID attribute of the form element to be verified plus the * sign indicates that this item is required. OFormValidate. addRule ("isNotNull", "* Card "); // OFormValidate. addRule ("isDate", "* Birthday "); // Call custom verification rules // AJAX verification the last one is the list of AJAX verification function parameters: 'getname. asp OFormValidate. addRule ("isExists", "Name", ["'getname. asp '"], oTip ); OFormValidate. addRule ("isLen", "* Password", [4, 8]); OFormValidate. addRule ("isSame", "* Password1", ["'password2 '"]); OFormValidate. listen (); }); }
