javascript - XMLHttpRequest; Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https, chrome-extension-resource

When I try to do a ajax call, I got the error on chrome below.

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

Here is code:

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