如何重用随机结果？

Question

<script type="text/javascript"> 
var a = new Array(
"Jane",
"Tom,", 
"Alan,",
"Mary");
</script>
<script type="text/javascript">
document.write(a[Math.floor(Math.random()*a.length)]);
</script>

ate an apple  

以后是否会在脚本中重用(a[Math.floor(Math.random()*a.length)])的答案？

例如，我稍后可以使用Harry asked "answer" if they had enjoyed the apple

行的文字

Answer 1

您可以将答案存储在变量

中

var ans = a[Math.floor(Math.random()*a.length)]

Answer 2

完成此任务的另一种方法

var a = new Array("Jane","Tom,", "Alan,","Mary");
// use a varible named "answer" for get the valu of "a" array value.
var answer =a[getRandomArbitrary(0,a.length)];

alert(answer);

// can use the "answer" variable anywhere like this.
alert("Harry asked "+answer+", if they had enjoyed the apple");

/*
function for get the integer value between two numbers.
*/
function getRandomArbitrary(min, max) {
    return parseInt(Math.random() * (max - min) + min);
}
