将javascrpt插入textarea？ [英] insert javascrpt into textarea?
问题描述
我有一个针对强盗语言的翻译程序。
i希望用户输入到顶部窗口然后显示
加密或解密底部的窗口。
i目前正在尝试通过python / webpy webapp执行此操作但是已经
告诉它可以用javascript完成。
我该怎么做？我无法从w3schools中找到它
教程。
我可以用javascript来调用另一个文件吗？或者我必须在下面的html文件中进行
翻译？它可能变得非常混乱...
< html>
< body bgcolor =" orange">
< center>
< h1>< p>< b>强盗的语言加密/解密器！< / b>< / p>< / h1>
< form method = post>
< p>
< select name =" encdec" ;>
< option value =" encrypt"> encrypt< / option>
< option value =" decrypt"> decrypt< / option> ;
< / select>
< / p>
< textarea name =" enc"行= QUOT; 10" cols =" 50"

您的Shift键出现故障。

在底部窗口加密或解密。

这并不奇怪，因为W3Schools的人显然不知道HTML
。避免使用此网站，它不适合作为Web开发参考。
我可以使用javascript调用另一个文件吗？或者我必须在下面的html文件中进行
翻译？它可能变得非常混乱...
我在下面阅读的内容与html文件相差甚远。
< html>
< body bgcolor =" orange">
orange不是已弃用的bgcolor属性的有效值。

无效，p元素不得包含在h1元素中。

< form method = post>
无效，action属性是必需的。

< p>
语义错误的元素，我们这里不是在讨论文本的段落。如果必须，请使用
`div''

你也应该设置'size''属性。

你不想使用XHTML。

见上文。

您不想提交此表格的信息，因此您不需要表格
元素。

至于你的问题，你可以用
< form action ="实现可选的客户端操作。 .." onsubmit =" return handleSubmit（this）">
< script type =" text / javascript">
function handleSubmit（）
{
...
//如果成功
返回false;
}

您不能指望无效内容有效;特别是你不能指望DOM
脚本在无效标记内和无效标记上工作。

where应该插入脚本吗？
我已经写过了。

我该怎么做？
请阅读< http://jibbering.com/faq/>。全部，特别是
介绍部分和那里引用的材料。
< html>
< script type =" text / javascript">
function myfunction（）
{
alert（" HELLO）;
}

它仍然无效。缺少DOCTYPE声明，而
'head''元素的开始和结束标记在HTML 4.01中是可选的
Transitional，'title''元素head元素不是。
http：// validator。 w3.org/
< body>
< center>
它仍然被弃用（HTML 4.01严格无效）。

i have a translator-program for the robbers language.
i want the user to input into the topwindow and then display the
encryption or decryption in the bottom window.
i am currently trying to do this via a python/webpy webapp but been
told it can be done with javascript.
how would i do this? i couldnt figure it out from the w3schools
tutorial.
and can i have a javascript to call another file? or i have to do the
translation in the html-file below? it could get very cluttery...

themselves. Avoid this site, it is not suitable as Web development reference.

scripting to work within and on invalid markup.

where should the script be inserted?I wrote that already.
id i do this, but want the script to write into the textarea instead,
how do i do that?Please read <http://jibbering.com/faq/>. All of it, especially the
introductory sections and the material referenced there.
<html>
<script type="text/javascript">
function myfunction()
{
alert("HELLO");
}
</script>It is still not Valid. The DOCTYPE declaration is missing, and while
the start and end tags for the `head'' element are optional in HTML 4.01
Transitional, the `title'' element within the `head'' element is not.
