http://www.o2fo.com/chun5060/chun5060-ot3p24bz.html

360.JavaScript 使用random()在一個(gè)范圍內(nèi)生成隨機(jī)數(shù)

```javascript // 舉例 function ourFunction(ourMin, ourMax) { return Math.floor(Math.random() * (ourMax - ourMin + 1)) + ourMin; } ourFunction(1, 9); // Only change code below this line. function randomRange(myMin, myMax) { return Math.floor(Math.random()*(myMax-myMin+1))+myMin; // Change this line...
