为什么我收到OPTIONS请求而不是GET请求?

本文介绍了为什么我收到OPTIONS请求而不是GET请求?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 <script src="ajax.googleapis/ajax/libs/jquery/1.3.2/jquery.js" type="text/javascript"></script> <script> $.get("example/", function(data) { alert(data); }); </script>

它对该URL进行OPTIONS请求，然后永远不调用回调函数.

it does an OPTIONS request to that URL, and then the callback is never called with anything.

当它不是跨网域时，就可以正常工作.

When it isn't cross domain, it works fine.

jQuery是否应该仅使用<script>节点进行调用，然后在加载时进行回调?我知道我将无法获得结果(因为它是跨域的)，但是没关系；我只想打通电话.这是一个错误，还是我做错了什么?

Shouldn't jQuery just make the call with a <script> node and then do the callback when its loaded? I understand that I won't be able to get the result (since it is cross domain), but that's OK; I just want the call to go through. Is this a bug, or am I doing something wrong?
