当您尝试将ajax调用到另一个域时会触发此问题，请查看此文章以获取有关Same的更多信息原始政策

为了解决这个问题，你需要添加此代码

For fix this, you will need to add this code

document.domain = 'yourdomain.com'

来自文章本身：

页面可能会因某些限制而改变自己的起源。脚本可以将document.domain的值设置为当前域的子集。如果它这样做，则较短的域用于后续的原始检查。例如，假设文档中的脚本位于 http://store.company.com/dir/other .html 执行以下语句：

document.domain = "company.com";

执行该语句后，页面将通过原点检查< a href =http://company.com/dir/page.html =noreferrer> http://company.com/dir/page.html 。但是，出于同样的原因，company.com无法将document.domain设置为othercompany.com。

After that statement executes, the page would pass the origin check with http://company.com/dir/page.html. However, by the same reasoning, company.com could not set document.domain to othercompany.com.

端口号由浏览器单独保存。对setter的任何调用，包括document.domain = document.domain都会导致端口号被null覆盖。因此，只能在第一个中设置document.domain =company.com，无法使company.com:8080与company.com交谈。必须在两者中设置它，以便端口号都为空。

The port number is kept separately by the browser. Any call to the setter, including document.domain = document.domain causes the port number to be overwritten with null. Therefore one cannot make company.com:8080 talk to company.com by only setting document.domain = "company.com" in the first. It has to be set in both so that port numbers are both null.
