| 编程（Programming）是编定程序的中文简称，就是让计算机代码解决某个问题，对某个计算体系规定一定的运算方式，使计算体系按照该计算方式运行，并最终得到相应结果的过程。为了使计算机能够理解（understand）人的意图，人类就必须将需解决的问题的思路、方法和手段通过计算机能够理解的形式告诉计算机，使得计算机能够根据人的指令一步一步去工作，完成某种特定的任务。这种人和计算体系之间交流的过程就是编程。 【实例名称】 弹出窗口生成器的JS代码怎么写 【实例描述】 IE中弹出窗口有很多方法，最常用的是“window．open”方法。本例制作一个自动生成弹出窗口代码的工具。 【实例代码】 <HTML>

【运行效果】  【难点剖析】 本例的重点在于“window．open”方法到底有多少个参数，这些参数通过“yes/no”来开关，具体参数的意义可参考body中的按钮文本。 【源码下载】 为了JS代码的准确性，请点击：弹出窗口生成器 进行本实例源码下载
使用编程语言写的程序，由于每条指令都对应计算机一个特定的基本动作，所以程序占用内存少、执行效率高。
