问题描述
我没有什么问题。我正在学习javascript，我想使用开关为我的网站创建随机标语生成器。
I have got little problem. I'm learning javascript and I wanted to create random slogan generator for my site with using switch.
所以我创建了这个HTML代码
So I created this html code
<body onload="rndqu()">
<div id="head"> <a href="index.html">Mira's place<a><br>
<h2>“<span id="quote"></span>”</h2>
</div>
</body>
并使用此Javascript
and used this Javascript
var qu;
var slogan;
function rndqu(n){
var random = function(min, max) {
return Math.floor(Math.random() * (max - min + 1)) + min;
};
qu = random(1, 3);
}
switch(qu){
case 1:
slogan = "Here is the 1";
break;
case 2:
slogan = "Here is the 2";
break;
case 3:
slogan = "Woah";
break;
default:
slogan = "Really?";
}
document.getElementById("quote").innerHTML = slogan;
我不明白为什么它不起作用。有人能帮我吗？谢谢！这里有jsfiddle http://jsfiddle.net/NX3cz/
I don't get it why it doesn't work. Can someone help me? Thank you! And here is jsfiddle of it http://jsfiddle.net/NX3cz/
推荐答案
您将部分代码留在 rndqu（）函数之外。
我在这里分叉并纠正了你的小提琴：

You left part of the code outside the rndqu() function.
I forked and corrected your fiddle here:

以下是更正的JS代码：
Here's the corrected JS code:
var qu;
var slogan;
function rndqu(n)
{
var random = function(min, max) {
return Math.floor(Math.random() * (max - min + 1)) + min;
};
qu = random(1, 3);
switch(qu){
case 1:
slogan = "Here is the 1";
break;
case 2:
slogan = "Here is the 2";
break;
case 3:
slogan = "Woah";
break;
default:
slogan = "Really?";
}
document.getElementById("quote").innerHTML = slogan;
}
