var item = myArray[Math.floor(Math.random()*myArray.length)]; 或更短的版本: var item = myArray[(Math.random()*myArray.length)|0]; 样例代码: var myArray = ['January', 'February', 'March']; var item = myArray[(Math.random()*myArray.length)|0]; console.log('item:', item);...
getRandomString(length) { const characters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789'; return Array.from({ length }, () => characters[Math.floor(Math.random() * characters.length)]).join(''); } 除了随机字符串之外一般还需要加一个时间参数,用于记录当前请求的时间。服务器接...
也就是说,这一步不需要我们进行什么操作,只要在WXML定义一个按钮,加上open-type="getPhoneNumber" bindgetphonenumber="getPhoneNumber"属性,然后在JS文件中写一个getPhoneNumber方法,该方法有一个参数e,我们可以从这个e中获取iv和encryptedData,这个encryptedData就是加密的数据,其中包括我们需要的电话号码。 那么,接...
BitGenerators: Objects that generate random numbers. These are typically unsigned integer words filled with sequences of either 32 or 64 random bits. Generators: Objects that transform sequences of random bits from a BitGenerator into sequences of numbers that follow a specific probability distributio...
下一步,通过使用Array.from我们将类型化数组转换为JavaScript数组,数组中包含我们提取帧中三种姿势的概率。如果既不是踢腿也不是拳击的姿势的概率高于0.4,我们将返回站立不动。 否则,如果显示高于0.32的概率拳击,我们会向MK.js发出拳击指令。 如果踢腿的概率超过0.32,那么我们发出一个踢腿动作。以下就是完整的...
