对于那些启用了 javascript 的用户，点击它们应该执行 OnClick()
对于那些禁用了 javascript 的用户，点击它们应该只是转到某个地方.html，
假设只有 $('#link') 可以访问，怎么办？
For those with javascript enabled,click on them should do OnClick()
For those with javascript disabled,click on them should just go to somewhere.html,
Suppose only $('#link') is accessible,how to do that?

像这样：
通过编写
return false，链接将不会被跟随。如果禁用 Javascript，则不会添加点击处理程序，并且链接将正常运行。
Like this:
By writing
return false, the link will not be followed.If Javascript is disabled, the click handler won't be added, and the link will behave normally.
$("#link").bind("click", function(e){alert("clicked"); e.preventDefault(); return false;});
这将警告“已单击”，然后取消默认操作。如果 JavaScript 被禁用，则链接将被跟随。
$("#link").bind("click", function(e){alert("clicked"); e.preventDefault(); return false;});
This will alert "clicked" and then cancel the default action. If Javascript is disabled, the link is followed.
使用
click函数。将return false添加到函数末尾以防止超链接后面的默认点击操作：Use the
clickfunction. Addreturn falseto the end of your function to prevent the default action of the click, which is following the hyperlink:
