阅读更多关于 Is there a way to both check a macro is defined and it equals a certain value at the same time

问题 I regularly use object-like preprocessor macros as boolean flags in C code to turn on and off sections of code. For example #define DEBUG_PRINT 1 And then use it like #if(DEBUG_PRINT == 1) printf("%s", "Testing"); #endif However, it comes a problem if the header file that contains the #define is forgotten to be included in the source code. Since the macro is not declared, the preprocessor treats it as if it equals 0, and the #if statement never runs. When the header file is forgotten to be

问题 I am working on an project and need to modify some code to resolve an error directive: (function () { 'use strict'; angular.module('myApp').directive("myDirective", function ($filter) { return { // code }; }); })(); This throws an error with the minified version only.

1.Directive的五个实例知道driective作用、其中字段restrict、template、 replace、transclude、link用法参考文章链接地址： http://damoqiongqiu.iteye.com/blog/1917971 1.指令（directive）的作用是把我们自定义的语义化标签替换成浏览器能够认识的HTML标签 ,如同博客中的自定义的<hello>标签 2.directive中几个属性的介绍： ①restrict：表明指令的声明方式，选项E(元素Element)，A（属性Attribute），C（样式类Class），M（注释Comment） ②template/templateUrl:替换自定义元素的html的标签及内容 ③replace:true/false :决定自定义标签的显示及隐藏 ④transclude:true决定自定义标签内子标签的内容的显示处理,此时<hello>标签里的内容保持不变 ⑤link:一些事件需要绑定到某个元素上，那么你需要提供一个link函数 http://www.cnblogs.com/jimmychange/p/3498906.html compile：在directive中如果需要对DOM元素进行处理，基本都是在这个函数中进行。仔细看这个函数，compile并不能访问scope， link
