返回目录 说在前 有时,我们在使用一个插件时,在网上即找不到它的相关API,这时,我们会很抓狂的,与其抓狂,还不如踏下心来,分析一下它的源码,事实上,对于JS这种开发语言来说,它开发的插件的使用方法都在它的源码里,只要你踏下心去看,一切就都有了! Knockout.Validation.js是为Knockout插件服务的,它可以为Knockout对象进行验证,就像你使用MVC模型验证一样,而这种绑定的验证方式对于开发人员来说是很容易接受的,也是一种趋势,它在验证过程中,会将出现异常的点记录下来,…

在Linux中,给kernel传递参数以控制其行为总共有三种方法: 1.build kernel之时的各个configuration选项. 2.当kernel启动之时,可以参数在kernel被GRUB或LILO等启动程序调用之时传递给kernel. 3.在kernel运行时,修改/proc或/sys目录下的文件. 这里我简单讲的就是第二种方式了,kernel在grub中配置的启动参数. 首先,kernel有哪些参数呢? 在linux的源代码中,有这样的一个文档Documentation/kern…
