直接使用ajax

clt_ip_temp.html:1 Failed to load http://127.0.0.1:8010/adverter/js: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access.

方法二：

    var ifoo = '<script src="http://127.0.0.1:8010/adverter/js"><\/script>';
    document.write(ifoo);

提示：

clt_ip_temp.html:88 A parser-blocking, cross site (i.e. different eTLD+1) script, http://127.0.0.1:8010/adverter/js, is invoked via document.write. The network request for this script MAY be blocked by the browser in this or a future page load due to poor network connectivity. If blocked in this page load, it will be confirmed in a subsequent console message. See https://www.chromestatus.com/feature/5718547946799104 for more details.
