问题描述
好吧，我想要做的是让b
）背景颜色随机改变5种不同的颜色。（更改
on页面加载）
2，）在
网页上的随机点中随机淡入和淡出10种不同的引号。有一个延迟计时器，所以他们不断变化，因为页面打开了。
。每次加载页面时都不随机。
如果有人可以提供帮助，那将是非常有用的，我已经尝试了很多
的东西，似乎无法得到我想要的东西。
它看起来如此简单却如此复杂......

Ok well what I am trying to do is have
1.) the background color to change randomly with 5 different colors.(change
on page load)
2,) 10 different quotes randomly fadeing in and out in random spots on the
webpage. with a delay timer on them, so they keep changing as the page is
open. Not random each time the page is loaded.
If anyone can help it would be greatly appreaciated, I have tried many of
things and just cant seem to get what I am looking for.
It seems so simple yet so complex...

将您的值放在数组中...
var quotes_array = new Array（）;
您可以填充数组...
quotes_array [0] ="这是一个引用" ;;
现在，你可以获得一个1到10之间的随机数：
var rand = Math.floor（Math.random（）* 10）+ 1;
您可以使用该随机数作为数组的索引：
alert（quotes_array [rand]）;
这有帮助吗？

Put your values in an array...
var quotes_array = new Array();
You can populate the array...
quotes_array[0] = "This is a quote";
Now, you can get a random number, between 1 and 10:
var rand = Math.floor(Math.random() * 10) + 1;
You can use that random number as an index to the array:
alert(quotes_array[rand]);
Does that help?

将你的值放在数组中......
var quotes_array = new Array（）;
你可以填充数组...
quotes_array [0] =" ;这是一个引用;
现在，你可以得到一个1到10之间的随机数：
var rand = Math.floor（Math.random（）* 10）+ 1 ;
您可以使用该随机数作为数组的索引：
alert（quotes_array [rand]）;
Put your values in an array...
var quotes_array = new Array();
You can populate the array...
quotes_array[0] = "This is a quote";
Now, you can get a random number, between 1 and 10:
var rand = Math.floor(Math.random() * 10) + 1;
You can use that random number as an index to the array:
alert(quotes_array[rand]);
你会希望随机数的范围从零到
到一个小于数组中元素的数量，
这简单地说：
var rand = Math.floor（Math.random（）* quotes_array.length）;
You''ll want the random number to range from zero up
to one less than the number of elements in the array,
which is simply:
var rand = Math.floor(Math.random()*quotes_array.length);

Put您在数组中的值...
var quotes_array = new Array（）;
您可以填充数组...
quotes_array [0] ="这是一个报价英寸;
或数组文字： -
var quotes_array = [
"这是一个引用，
" This is quote 2"，
" This is quote 3"，
" This is quote 4"
];
现在，您可以获得1到10之间的随机数：
var rand = Math.floor（Math.random（）* 10）+ 1 ;
或者： -
var rand = Math.ceil（Math.random（）* 9）;
但javascript数组基于零。
您可以使用该随机数作为数组的索引：
alert（quotes_array [rand]）;
Put your values in an array...
var quotes_array = new Array();
You can populate the array...
quotes_array[0] = "This is a quote";
Or an Array literal:-
var quotes_array = [
"This is a quote",
"This is quote 2",
"This is quote 3",
"This is quote 4"
];
Now, you can get a random number, between 1 and 10:
var rand = Math.floor(Math.random() * 10) + 1;
Or:-
var rand = Math.ceil(Math.random() * 9);
But javascript arrays are zero based.
You can use that random number as an index to the array:
alert(quotes_array[rand]);
所以基于数组长度的随机数将保存
两段代码失效： -
var rand = Math.floor（Math.random（）* quotes_array.length）;
从数组中随机选择有合理的概率
重复选择相同的元素。
随机抽取数组内容然后循环遍历
结果可能会更好。
Richard 。
So basing the random number on the length of the array would save the
two pieces of code getting out of step:-
var rand = Math.floor(Math.random() * quotes_array.length);
Randomly selecting from an Array has a reasonable probability of
repeatedly selecting the same element. It would probably be better to
randomly shuffle the contents of the array and then loop through the
results sequentially.
Richard.
