我在apache服务器上有一个mp3.我希望在用户访问链接时将其下载为文件.而不是quicktime,或谷歌chromes媒体播放器将尝试流式传输.
有标题的解决方案吗?或者是唯一的选择,所以'右键单击另存为'?
编辑这是我的标题.Safari已经停止了流媒体,但是chrome已经停止了.Chrome似乎忽略了这一点:
我可以看到标题已正确更改:

标题中是否还有其他内容会导致此问题?
编辑我做了一些调查我发现:http : //www.google.com/support/forum/p/Chrome/thread?tid= 76de4f53f43f03d3 & hl= en看起来Chrome中可能存在一个错误,导致无法下载.

我收集的是由于日志功能的多个版本.显然我可以在日志函数周围编写一个简单的包装器并用它调用它.有没有更简单的方法来指定我想要内联的日志功能?
有没有办法使用邮政编码找到径向距离?
我的任务是搜索居住在指定距离内的所有用户.我知道用户的zipcodes.
例如,距离当前位置25英里的用户.
我有其他搜索类别,我正在使用mysql查询.我无法解决距离问题.
我的后端是在Flex中的php和前端.
对我来说最好的选择就是www.zip-codes.com/zip-code-radius-finder.asp.即,如果我能够在指定的径向距离内获得所有可用的邮政编码.所以我可以将此邮政编码与我数据库中的用户邮政编码进行比较.并选择匹配的.
这个你能帮我吗.Zeeshan
我只是想尝试一个非常简单的jQuery动作.
我有两个组件:#safety并且#safety-tab a,#safety需要在加载时隐藏.当该链接#safety-tab被点击,它会hide本身slideUp的#safety.
这种作品,但#safety只是点击闪烁的框,不会显示:
$(document).ready(function() {
$("#safety-tab a").click(function() {
$(this).hide();
$("#safety").removeClass("hide");
});
});

<div id="safety-tab">

假设您有一个网络应用程序,人们可以在其中提交链接,自己网站的链接以及他们不拥有的网站链接.提交表单在两种情况下几乎相同,除非他们提交链接的域名.
如果用户从他们自己注册的网站列表中提交,他们将获得他们网站的下拉列表.
If the user is submitting a link the user types the domain into a field whose value I get in the "link" model through an attr_accessor. The "link" model then executes a find_or_create method on that domain.
Right now my solution is unsatisfactory: When the user clicks "Submit Link" I put ?other=prompt into the url and then have this kind of conditional:
<% if params[:other] == "prompt" %>
<div class="prompt_form">

I was practicing with some simple delete/insert routines, when encountered with this: if I ONLY insert records:
all is ok, then I call a delete procedure, passing the colum_ID to identify the record and delete it.
This is done correctly and all is OK
Then I call a insert procedure once again and the insert happens like this:

Any insight would be helpful, thanks.

I have a couple of commits where my email address is wrong in the history.
How can I rewrite this history to reflect the correct email address?
If I choose to rewrite history, what is it that another user will have to do to fix their checkout?

<img src="..." />
<img src="..." />
<div style="text-align:right display:inline;">
