没有标准方法。 DOM 2事件规范定义了将HTML，鼠标和UI事件分派到文档树中的方式，但是未指定
键盘事件。 DOM 3事件规范确实是
添加键盘事件，但规范从未达成一致，所以
几个[1]浏览器实现了它。
这意味着你可以做的任何事情，*可能*在Mozilla和IE中工作，但是
它在其他任何地方都不太可能有效。
对不起，
Mike
[1] Mozilla做了，但他们的实施是早期的，属性
和方法已经改变从那以后。

替换.invalid与.uk通过电子邮件回复
There is no standard approach. The DOM 2 Events Specification defined ways
of dispatching HTML, mouse, and UI events into the document tree, but
keyboard events were not specified. The DOM 3 Events Specification does
add keyboard events, but the Specification was never agreed upon, so
few[1] browsers implemented it.
That means that anything you might do, *might* work in Mozilla and IE, but
it''s highly unlikely to work anywhere else.
Sorry,
Mike
[1] Mozilla did, but their implementation was made early, and properties
and methods have changed since.

您似乎只针对IE，因此该解决方案仅限IE。注意
触发按键事件不会处理内置的
事件前的机制，即你在textarea中看不到任何字母。对于操纵textarea值的
，使用IE范围。
虽然触发事件的想法很好，但我相信那里
通常是更好的方法，使用处理程序和代理，但不是
知道你想做什么使得很难确定最好的方法： - ）

< form>
< textarea onkeypress =" foo（this，event）">< / textarea>
< input type =" button"值= QUOT;栏（）" onclick =" bar（）">
< / form>
< script type =" text / javascript">
函数foo（elem，evt）{
alert（
[
" elem：" + elem .nodeName，
" shiftKey：" + evt.shiftKey，
" keyCode：" + evt.keyCode
]。加入（" \ n"）
）;
}
功能栏（）{
if（document.createEventObject）{
var evt = document.createEventObject（）;
evt.shiftKey = true;
evt .keyCode = 121;
document.forms [0] .elements [0] .fireEvent（" onkeypress"，evt）;
}
}

HTH，
是的。
You seem to be targeting IE only, so the solution will be IE only. Note
that triggering a keypress event does not deal with the built-in
pre-event mechanics, i.e. you won''t see any letter in your textarea. As
for manipulating the textarea''s value, use IE ranges.
Though the idea of triggering events is a good one, I believe that there
usually are better approaches, using handlers and "proxies", but not
knowing what you want to do makes it difficult to determine the best one:-)

<form>
<textarea onkeypress="foo(this, event)"></textarea>
<input type="button" value="bar()" onclick="bar()">
</form>
<script type="text/javascript">
function foo(elem, evt){
alert(
[
"elem : " + elem.nodeName,
"shiftKey : " + evt.shiftKey,
"keyCode : " + evt.keyCode
].join("\n")
);
}
function bar(){
if(document.createEventObject) {
var evt=document.createEventObject();
evt.shiftKey=true;
evt.keyCode=121;
document.forms[0].elements[0].fireEvent("onkeypress", evt);
}
}
</script>

HTH,
Yep.

我想我也不知道自己:)但我不认为这是我的问题的解决方案
。当我在阅读关于这个主题的更多内容时，我也注意到了
这里的方法名为''handleEvent（）''。
fireEvent和handleEvent有什么区别？

I think I don''t know myself either :) But I don''t think this is the solution
to my problem. While I was reading some more on this subject I also noticed
there''s method called ''handleEvent()''. What''s the difference between
fireEvent and handleEvent?
