javascript-XMLHttpRequest;跨源请求仅支持以下协议方案：http,数据,chrome,chrome扩展名,https,chrome-extension-resource

当我尝试进行ajax调用时,在下面的chrome中出现了错误.

XMLHttpRequest cannot load javascript:;. Cross origin requests are
only supported for protocol schemes: http, data, chrome,
chrome-extension, https, chrome-extension-resource.

这是代码：

$.ajax({
    type: "POST",
    data: {pvalue : pid},
    cache: false,
    url: "xxx.in/yy/ajax.PHP",
    success: function(data)
    {
      $modal.find('.edit-content').html(data);
    }

解决方法:

所有对该特定错误消息的研究都表明,主机网页未通过http：// URL加载,并且可能是文件URL.默认情况下,浏览器将不允许来自文件URL的跨源请求.

如果要使用ajax请求,则需要通过Web服务器而不是文件系统加载Web页面.

以下是有关该特定错误的其他一些问题和答案,所有这些均指向用于加载页面的错误URL类型.
