崩溃了,这样的js写法你们见过么?希望能得到详细的指点
function interfaceInit(){
Dialog = (function (){
var now = null;
return {
add : function (id){
alert( id);
},
getNow : function(){
alert(now);
}
}
})();
}
这到底是函数还是对象啊?怎么会有这样的写法?我怎么调用?
这样的写法有什么好处?写得是人都看不懂的!
------解决方案--------------------
interfaceInit 应该是面向对象里的接口
所有继承了interfaceInit这个接口的类或函数,都要定义Dialog函数。
------解决方案--------------------
那Dialog函数里面又有add和getNow两个方法,怎么调用呢?
==========
- JScript code
var init = new interfaceInit(); init.Dialog.add(); init.Dialog.getNow(); <br><font color="#e78608">------解决方案--------------------</font><br>这样改会不会看得明白点?<br>可以把下面的代码扔到页面中,应该会alert出2.<br>
- JScript code
<script> var Dialog = {}; function interfaceInit(){ var now = null; Dialog = { add : function(id){ alert(id); }, getNow : function(){ alert(now); } } } var interface = new interfaceInit(); (function(){ var dialog = Dialog; dialog.add(2); })() </script> <br><font color="#e78608">------解决方案--------------------</font><br> Js类 匿名对象. <br><font color="#e78608">------解决方案--------------------</font><br>To:xuStanly<br>你自己写的代码有做过测试吗?!<br><br>To:foolbirdflyfirst<br>

- JScript code
<script type="text/javascript"> function interfaceInit(){ Dialog = (function(){ var now = null; return { add: function(id){ alert(id); }, getNow: function(){ alert(now); } } })(); } interfaceInit(); Dialog.add(123); </script> <br><font color="#e78608">------解决方案--------------------</font><br>这种格式非常正常,如果你深入的了解了js,就会发现如果想实现一些比较高级的应用,js代码只能这么写,建议楼主看看<br><javascript>(也就是O'reilly的犀牛书),重点学习一下与函数,对象相关的章节<br>然后,可以找一个比较流行的js框架学习一下他的源代码,比如prototype <div class="clear"> </div></javascript>

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
