缺少doctype声明。
http://www.htmlhelp.com/tools/validator/doctype.html
< head>
< title>测试表格< / title>
< script language =" JavaScript"类型= QUOT;文本/ JavaScript的">
<head>
<title>Test Form</title>
<script language="JavaScript" type="text/javascript">
< scripttag未关闭。
<scripttag not closed.
< / head>
< body>
< script type =" text / javascript">
document.EmailFound.CMName.value = Fanny;
< / script>
</head>
<body>
<script type="text/javascript">
document.EmailFound.CMName.value="Fanny";
</script>
document.EmailFound.CMName目前还不是
代码执行的对象。基本流程仍然是自上而下的。
为了更好的向后兼容性，还可以使用：
document.forms ['' EmailFound'']。elements [''CMName'']。值
代替
document.EmailFound.CMName.value
document.EmailFound.CMName is not an object yet at this point of the
code execution. The basic flow is still top-down.
For a better backwards compatibility, one could also use:
document.forms[''EmailFound''].elements[''CMName''].value
in stead of
document.EmailFound.CMName.value
< form method =" POST"名称= QUOT; EmailFound" id =" EmailFound">
< input name =" CMName" />
<form method="POST" name="EmailFound" id="EmailFound">
<input name="CMName" />
虽然不是严格要求，但这应该是< input type =" text"
name =" CMName">。
Though not strictly required, this should be <input type="text"
name="CMName">.
< input type =" submit"值= [提交"命名= [提交" />
< / form>
< / body>
< / html>
<input type="submit" value="Submit" name="submit" />
</form>
</body>
</html>
所有在一起：
<！doctype HTML public" - // W3C // DTD HTML 4.01 // EN"
" http：//www.w3.org/TR/html4/strict.dtd">
< html>
< head>
< title>测试表格< / title>
< / head>
< body
onLoad =" document.EmailFound.CMName.value =''Fanny'';" >
< form method =" POST" name =" EmailFound">
< input type =" text" name =" CMName">
< input type =" submit" value =" Submit">
< / form>
< / body>
< / html>
''onLoad''事件处理程序在页面完全加载完毕后执行。
希望这有助于，

All together:
<!doctype HTML public "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title>Test Form</title>
</head>
<body
onLoad="document.EmailFound.CMName.value=''Fanny'';" >
<form method="POST" name="EmailFound">
<input type="text" name="CMName">
<input type="submit" value="Submit">
</form>
</body>
</html>
The ''onLoad'' event handler is executed right after the page has fully
loaded.
Hope this helps,

谢谢你们两位，它很棒！
但是现在我想放回一些我为了
而剥离的代码示例，我再也无法让它工作了。
我不想要范妮要硬编码，但要从
函数调用返回。这是经过调整的代码，带有精简的
功能：
================== ===============================
<！doctype HTML public" ; - // W3C // DTD HTML 4.01 // EN"
" http：//www.w3.org/TR/html4/strict.dtd">
< html>
< head>
< title>测试表格< / title>
< / head>
< script type =" text / javascript">
function getValue（）;
return" Fanny" ;
< / script>
< body
< form method =" POST" name =" EmailFound">
< input type =" text" name =" CMName">
< input type =" submit" value =" Submit">
< / form>
< script type =" text / javascript">
document.EmailFound.CMName.value = getvalue（）;
< / script>
< / body>
< / html>
============================= ====================
Thank you both, it works great!
But now that I want to put back some of the code I stripped out for
the example, I can''t get it to work again.
I don''t want "Fanny" to be hardcoded, but to be returned from a
function call. Here is the adjusted code with a stripped-down
function:
=================================================
<!doctype HTML public "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title>Test Form</title>
</head>
<script type="text/javascript">
function getValue();
return "Fanny";
</script>
<body
<form method="POST" name="EmailFound">
<input type="text" name="CMName">
<input type="submit" value="Submit">
</form>
<script type="text/javascript">
document.EmailFound.CMName.value=getvalue();
</script>
</body>
</html>
=================================================
