blocks|key|240088|text|对我来说，正确的方法应该是下面列出的方法。ajax或ajaxSetup。如果您真的想使用get而不使用ajaxSetup，那么您可以创建自己的参数，并为其提供当前日期/时间的值。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|240089|然而，我会质疑你不使用其他方法之一的动机。|240090|entityMap^0|L|4|Q|9|18|3|1F|9|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]|$9|M|A|N|B|C]|$9|O|A|P|B|C]|$9|Q|A|R|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|S|8|@]|D|@]|E|$]]|$1|H|3|-4|5|6|7|T|8|@]|D|@]|E|$]]]|I|$]]

To me, the correct way of doing it would be the ones listed. Either <code>ajax</code> or <code>ajaxSetup</code>. If you really want to use <code>get</code> and not use <code>ajaxSetup</code> then you could create your own parameter and give it the value of the the current date/time.

I would however question your motives in not using one of the other methods.

blocks|key|245120|text|我认为你必须使用AJAX方法，它允许你关闭缓存：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|245121|$.ajax({

I think you have to use the AJAX method instead which allows you to turn caching off:

 data: 'foo',
 success: function(){
 alert('bar');
 },
 cache: false
});
</code></pre>

blocks|key|2913999|text|根据JQuery文档，.get()仅使用url、data+(content)、dataType和success回调作为其参数。在这里，您真正要做的是在发送之前修改jqXHR对象。对于.ajax()，这是通过beforeSend()方法完成的。但由于.get()是一条捷径，它不允许这样做。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|2914000|不过，将.ajax()调用切换到.get()调用应该相对容易。毕竟，.get()只是.ajax()的一个子集，所以您可能可以使用.ajax()的所有默认值(当然，beforeSend()除外)。|2914001|编辑：|BOLD|2914002|：：看着Jivings的回答|2914003|哦，对了，忘了cache参数了！虽然beforeSend()对于添加其他头文件很有用，但是内置的cache参数在这里要简单得多。|2914004|entityMap^0|B|6|K|3|O|4|13|8|1C|7|2J|7|2V|C|3G|6|0|4|7|G|6|Y|6|16|7|1S|7|29|C|0|0|3|0|0|7|5|I|C|1C|5|0^^$0|@$1|2|3|4|5|6|7|Q|8|@$9|R|A|S|B|C]|$9|T|A|U|B|C]|$9|V|A|W|B|C]|$9|X|A|Y|B|C]|$9|Z|A|10|B|C]|$9|11|A|12|B|C]|$9|13|A|14|B|C]|$9|15|A|16|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|17|8|@$9|18|A|19|B|C]|$9|1A|A|1B|B|C]|$9|1C|A|1D|B|C]|$9|1E|A|1F|B|C]|$9|1G|A|1H|B|C]|$9|1I|A|1J|B|C]]|D|@]|E|$]]|$1|H|3|I|5|6|7|1K|8|@$9|1L|A|1M|B|J]]|D|@]|E|$]]|$1|K|3|L|5|6|7|1N|8|@]|D|@]|E|$]]|$1|M|3|N|5|6|7|1O|8|@$9|1P|A|1Q|B|C]|$9|1R|A|1S|B|C]|$9|1T|A|1U|B|C]]|D|@]|E|$]]|$1|O|3|-4|5|6|7|1V|8|@]|D|@]|E|$]]]|P|$]]

Per the JQuery documentation, <code>.get()</code> only takes the <code>url</code>, <code>data</code> (content), <code>dataType</code>, and <code>success</code> callback as its parameters. What you're really looking to do here is modify the jqXHR object before it gets sent. With <code>.ajax()</code>, this is done with the <code>beforeSend()</code> method. But since <code>.get()</code> is a shortcut, it doesn't allow it.

It should be relatively easy to switch your <code>.ajax()</code> calls to <code>.get()</code> calls though. After all, <code>.get()</code> is just a subset of <code>.ajax()</code>, so you can probably use all the default values for <code>.ajax()</code> (except, of course, for <code>beforeSend()</code>).

Edit:

::Looks at Jivings' answer::

Oh yeah, forgot about the <code>cache</code> parameter! While <code>beforeSend()</code> is useful for adding other headers, the built-in <code>cache</code> parameter is far simpler here.

blocks|key|243817|text|我在游戏中很晚，但这可能会对其他人有所帮助。我用$.get遇到了同样的问题，我不想盲目地关闭缓存，我也不喜欢时间戳补丁。因此，经过一些研究后，我发现您可以简单地使用$.post而不是不使用缓存的$.get。就这么简单。:)|type|unstyled|depth|inlineStyleRanges|entityRanges|data|243818|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I'm very late in the game, but this might help others.
I hit this same problem with $.get and I didn't want to blindly turn off caching and I didn't like the timestamp patch.
So after a little research I found that you can simply use $.post instead of $.get which does NOT use caching. Simple as that. :)

Set cache: false in jQuery.get call using Below Method

use new <code>Date().getTime(),</code> which will avoid collisions unless you have multiple requests happening within the same millisecond.

Or

The following will prevent all future AJAX requests from being cached, regardless of which jQuery method you use ($.get, $.ajax, etc.)

<pre><code>$.ajaxSetup({ cache: false });

<code>jQuery.get()</code> is a shorthand for <code>jQuery.ajax()</code> with a get call. But when I set <code>cache:false</code> in the data of the <code>.get()</code> call, what is sent to the server is a parameter called cache with a value of false. While my intention is to send a timestamp with the data to the server to prevent caching which is what happens if I use <code>cache: false</code> in jQuery.ajax data. How do I accomplish this without rewriting my jQuery.get calls to jQuery.ajax calls or using 

<pre><code>$.ajaxSetup({
 // Disable caching of AJAX responses
 cache: false
});
</code></pre>

update: Thanks everyone for the answers. You are all correct. However, I was hoping that there was a way to let the get call know that you do not want to cache, or send that value to the underlying .ajax() so it would know what to do with it.

I a. looking for a fourth way other than the three ways that have been identified so far:

<ol>
<li>Doing it globally via ajaxSetup</li>
<li>Using a .ajax call instead of a .get call</li>
<li>Doing it manually by adding a new parameter holding a timestamp to your .get call.</li>
</ol>

I just thought that this capability should be built into the .get call.
