在Navigator中调用链接单击事件 [英] invoke link click event in Navigator
问题描述
我可以在IE中这样做
myLink.click（）; //调用处理程序就好像用户自己点击了
链接一样。
我需要能够在Netscape Navigator中执行相同操作，
有人可以帮忙吗？
I can do this in IE
myLink.click(); //Invoking the handler as if the user had clicked on the
link themselves.
I need to be able to do the same in Netscape Navigator,
can anyone help ?

我的导航器安装坏了，我要解决它，但我怀疑
上面的工作正常（它确实在IE和Firefox ......）

修正了我的NN安装，上面修复似乎工作正常。如果你担心该链接可能有一个onclick事件，如果你刮掉href可能不会执行
，那么试试：
if（myLink.href）{
if（！myLink.onclick）{
document.location.href = myLink.href;
} else {
if（false！= myLink.onclick（））{
document.location.href = myLink.href;
}
}
}
这样可以合理地模拟A元素上的点击
（除非还有一些其他事件 - 例如keyup，keydown等 - 你想支持
）。
上面看来看看myLink是否有一个href属性。如果是这样，如果支持onclick内部事件，它会看到
，如果没有，则链接是
跟随。
如果支持onclick，它尝试运行onclick（）脚本。如果
它返回除 - false之外的任何内容 - 则遵循链接。如果返回
- false - 则不会跟踪链接（没有任何反应）。
但是，这里存在严重的可访问性问题：没有用户
JavaScript根本无法关注链接。您必须提供
替代方案，以便这些用户可以关注链接。通常的解决方法是使用
提供正常的A元素，然后在页面加载时使用脚本
用JS''增强型'版本替换普通导航。 br $> b $ b -

Fixed my NN install, the above fix seems to work fine. If you are
concerned that the link may have an onclick event that may not be
executed if you scrape the href, then try:
if ( myLink.href ) {
if ( ! myLink.onclick ) {
document.location.href = myLink.href;
} else {
if ( false != myLink.onclick() ) {
document.location.href = myLink.href;
}
}
}
This provides a reasonable simulation of a click on an A element
(unless there are some other events - e.g. keyup, keydown, etc. - that
you want to support).
The above looks to see if myLink has an href attribute. If so, it sees
if the onclick intrinsic event is supported, if not, the link is
followed.
If onclick is supported, it attempts to run the onclick() script. If
it returns anything other than - false - the link is followed. If
- false - is returned, then the link is not followed (nothing happens).
However, there is a serious accessibility issue here: users without
JavaScript can''t follow the link at all. You must provide an
alternative so that these users can follow links. The usual fix is to
provide normal A elements, then use a script when the page loads to
replace the normal navigation with your JS ''enhanced'' version.

感谢您的帮助，不幸的是，这不是我想要的那样/>
，或许我应该更具体。我正在尝试为MailTo链接调用
邮件助手。使用链接的click事件为
IE和NN执行此操作，但我可以在NN上调用该事件。我需要构建
MailTo：使用Javascript以便我可以自定义外发邮件。
我知道还有其他方法可以使用表单执行此操作和一些CGI
脚本或其他什么，但更喜欢这种方法。我知道你可能会说达到是一个问题，因为不是每个人都有他们的浏览器帮助，无论如何这是我想要实现的目标。
你知道如何用Javascript（
NN）以编程方式调用click事件，我非常想知道答案吗？
最好的问候

新闻：Ft ***************** @ news.optus.net.au ...
Thanks for your help, unfortunately, this was not quite what I was looking
for, perhaps I should have been more specific. I am trying to invoke the
mail helper for the MailTo link. Using the link''s click event does this for
IE and NN, but I can invoke the event on NN. I need to construct the
MailTo: using Javascript so I can customise the outgoing mail message.
I know there are other ways of doing this using a form and a bit of CGI
script or whatever, but prefer this method. I know you may say reach is an
issue because not everyon has helpers on their browser, in any case this is
what I am trying to acheive.
Do you know how to invoke the click event programatically in Javascript (
NN ), I would dearly like to know the answer to that ?
Best Regards
