In JavaScript, we can generate random numbers using the Math.random() function. Unfortunately, this function only generates floating-point numbers between 0 and 1.In my experience, it's much more common to need a random integer within a certain range. For example, a random number between 10...

You can useMath.floor()to get a random integer value.Math.floor()returns the number by decreasing the value to the nearest integer value. For example, Math.floor(5.389);// 5Math.floor(5.9);// 5 The syntax to find the random integer value between two numbers: ...
说到JavaScript脚本,iOS开发者都会想到一个名叫JavaScriptCore的框架。这个框架的确十分强大,其中封装了一套JavaScript运行环境以及Native与JS数据类型之间的转换桥梁。本篇博客主要讨论如何使用此框架来在iOS应用中运行JavaScript脚本。 一、JavaScriptCore框架结构
