js异常处理

js错误处理的方式多种，比较常用的是try-catch-finally。现在用onerror(该方法触发时有3个三个参数：ErrorMessage(错误报告消息)、URL(发生错误的URL地址)、LineNumber(错误所在行数))处理.我们在开发阶段希望将错误信息提出出来，则可以这样子处理：<%@pagelanguage="java"import="java.util.*"pageEncoding="UTF-8"%><%Stringpath=reque

关于inline函数

（一）inline函数（摘自C++Primer的第三版）在函数声明或定义中函数返回类型前加上关键字inline即把min（）指定为内联。inlineintmin(intfirst,intsecend){/****/};inline函数对编译器而言必须是可见的，以便它能够在调用点内展开该函数。与非inline函数不同的是，inline函数必须在调用该函数的每个文本文件中定义。当然，对于同一程序的不同文件，如果inline函数出现的话，其定义必须相同。对于由两
