事件和形象 [英] events and image
问题描述
小组，
长话短说，我是JavaScript的新手，已经开始不到3
周。我的问题是
1）我怎样才能创建一种当用户点击gif或...时的情况。
图像文件触发事件？
我所做的是：
测试图像：
< a href ="" name =" linkImg1"
onclick =" javascript ：my_trker（'''http://www.mywebsite.com/akohan''）;" >
< img name = img1 src =" flower.gif" border = 0>
< / a>
问题是，当我点击此图片时，它会通过
功能，但页面更改为路径：
http：// www。 mywebsite.com/akohan 并显示我在那里的
文件的列表或目录！
2）是否可以在Javascript中创建新事件？如果是这样，当用户右键点击链接或图像时，我怎么能监视一个事件呢？
你的帮助将被用来。
amit。
Hi group,
Long story short, I''m new to JavaScript and have started it less than 3
weeks. My question is
1) how can I create a situation that when user clicks on gif or ...
image file an event get triggered?

Testing image:
<a href="" name="linkImg1"
onclick="javascript:my_trker(''http://www.mywebsite.com/akohan'');" >
<img name=img1 src="flower.gif" border=0 >
</a>
the problem is that when I click on this image it goes thru the
function but then the page changes to the path:
http://www.mywebsite.com/akohan and shows a list or directory of the
files I have there!
2) Is it possible to create new events in Javascript? lf so, how can I
monitor an event when user does a right-click on a link or image?

原因是：href =""。如果你想停止点击
，你需要在你的onclick上添加return false：
onclick =" doSomething（）;返回false
BTW，''javascript ：''不需要onclick
- <对于所有构成的事实而言，最令人费解的解释是阴谋理论家最有可能相信的事情。
。安装
实际事实是可选的。
The reason for that is: href="". If you want to STOP the click from
going through, you need to add return false to your onclick:
onclick = "doSomething(); return false"
BTW, ''javascript:'' is not needed for onclick

因为你在那里用链接导航了。

http://www.mywebsite.com/akohan and shows a list or directory of the
files I have there!
Because you navigated there with the link.
2) Is it possible to create new events in Javascript? lf so, how can I
monitor an event when user does a right-click on a link or image?

谢谢Tony，
我感谢你的帮助。你能告诉我一个图像的格式是什么？可以点击的
标签？
以下标签是可点击的，但它没有通过名字和
文件的路径！
测试图像：
< a href ="" name =" linkImg1"
onclick =" javascript ：my_trker（'''http://www.mywebsite.com/akohan''）;" >
< img name = img1 src =" flower.gif" border = 0>
< / a>
我需要传递一些信息，即路径，文件名到函数。
任何线索？
谢谢，
amit

tag which is clickable?
The following tag is clickable but it doesn''t pass the name and path of
the file!
Testing image:
<a href="" name="linkImg1"
onclick="javascript:my_trker(''http://www.mywebsite.com/akohan'');" >
