再次...“$ 未定义” - 尝试实施 sIFR
我的文件开头看起来像这样：
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>My title</title>
<link rel="stylesheet" type="text/css" href="css/style.css" />
<script src="js/update.js" type="text/javascript"></script>
<!-- sifr -->
<link href="sifr207/sIFR-screen.css" rel="stylesheet" type="text/css" media="screen" />
<script src="sifr207/sifr.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function()
{
if(typeof sIFR == "function")
{
sIFR.replaceElement("sifr", named({sFlashSrc: "sIFR-2.0.7/corporateacon-reg.swf", sColor: "#FF0000" , sWmode: "transparent"}));
};
});
</script>
<!-- -->
</head>
我真的不明白为什么找不到 '$(document).ready(function()' ，因为我在调用之前实现了 sifr.js 。
有什么建议吗？ 我会很感激它，真的！
喊， 监督
my file beginning looks like this:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>My title</title>
<link rel="stylesheet" type="text/css" href="css/style.css" />
<script src="js/update.js" type="text/javascript"></script>
<!-- sifr -->
<link href="sifr207/sIFR-screen.css" rel="stylesheet" type="text/css" media="screen" />
<script src="sifr207/sifr.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function()
{
if(typeof sIFR == "function")
{
sIFR.replaceElement("sifr", named({sFlashSrc: "sIFR-2.0.7/corporateacon-reg.swf", sColor: "#FF0000" , sWmode: "transparent"}));
};
});
</script>
<!-- -->
</head>
I really do not understand why the '$(document).ready(function()' is not found, because I implement sifr.js BEFORE that call.
Any suggestions?
I would appriciate it, really!

您的文件中没有包含 jQuery.js！
由于 SIFR 是一个 jQuery 插件，因此您必须在
sifr.js之前加载基础库。尝试添加
you do not have jQuery.js included in your file!
Since SIFR is a jQuery plugin, you have to load the base library before
sifr.js.Try adding
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript></script>at the beginning of your script.似乎您在调用之前没有包含任何对 JQuery 的引用，这就是 '$' 未定义的原因。尝试在之前添加此内容：
Seems like you didn't include any reference to JQuery before that call, that's why '$' is undefined. Try to add this before:
因为 sIFR 没有实现
$函数。您可能打算使用 Prototype.js、jQuery 或其他一些使用该错误命名变量的库。Because sIFR doesn't implement a
$function. You probably mean to use Prototype.js, jQuery, or some other library that uses that badly named variable.$(document).ready(callback)是 jQuery 库提供的方法文档解析完成后运行callback。您的文件中似乎没有引用 jQuery 的脚本，因此此方法不可用。$(document).ready(callback)is a method provided by the jQuery library to runcallbackwhen the document parsing has completed. It looks like you don't have a script referencing jQuery in your file, so this method is not available.只需在加载 sifr 之前将 jQuery 添加到您的 head 即可。
Simply add jQuery to your head before sifr is loaded.
