我想不通这到底是怎么回事。作为测试，我的代码应该在页面顶部写一些东西。那下面应该有一张 table 。然而，所发生的只是一个空白页面以正确的背景颜色显示。
你觉得这里有什么好笑的吗？
<html>
<head>
<title>Simple encrypt/decrypt</title>
<style type="text/css">
body
{
background-color: #A9F5F2;
}
#divuno
{
height: 700px;
width: 100%;
}
</script>
<script type="text/javascript">
function encrypt(thisString)
{
retString = "";
/* Make retString a string of the bit representations of
the ASCII values of its thisCharacters in order.
*/
for (i = 0, j = thisString.length; i < j; i++)
{
bits = thisString.thisCharCodeAt(i).toString(2);
retString += new Array(8-bits.length+1).join('0') + bits;
}
/* Compress retString by taking each substring of 3, 4, ..., 9
consecutive 1's or 0's and it by the number of such consecutive
thisCharacters followed by the thisCharacter.
EXAMPLES:
"10101000010111" --> "10101401031"
"001100011111111111111" --> "0011319151"
*/
retString = retString.replace(/([01])\1{2,8}/g, function($0, $1) { return ($0.length + $1);});
return retString;
}
function decrypt(thisString)
{
thisString.trim();
var result = "", thisChar = "";
for (var i = 0, j = thisString.length(); i < j; ++i)
{
thisChar = thisString.thisCharAt(i);
console.log(thisChar - '0');
if (thisChar > 1)
result += new Array(+thisChar + 1).join(thisString.thisCharAt(++i));
else
result += thisChar;
}
if (!(result.length % 8))
{
alert ("Improper input; cannot decrypt");
return;
}
for (var i = 0, j = result.length; i < j; i += 8)
{
result = "";
result += parseInt(thisString.substr(i,8), 2);
}
return result;
}
</script>
</head>
<body>
<script type="text/javascript">
document.write(encrypt("Yo, dawg, I heard you like functions"));

<div id="divuno">

最佳答案
您输入了 thisCharCodeAt而不是 charCodeAt .你还有</script>而不是 </style> ，导致文档的其余部分被视为样式表。
关于javascript - 根据 Chrome 的 JavaScript 控制台，没有 JavaScript 错误，但我的页面无法正常工作，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/22467007/
