oAjax = new ActiveXObject("Microsoft.XMLHTTP");
}
oAjax.open("get","url",true)
oAjax.send()
oAjax.Onreadystatechange=function()
{
if(oAjax.readyState == 4)

{
fnSucc(oAjax.responseText);
}

if(fnFaild)
{
fnFaild();
}
}
}
} |
}
html文件：
在调试中宝了这样的一错误提示：
new_ajax.js:26 Access to XMLHttpRequest at 'file:///Users/yusunqi/Desktop/%E6%B5%8B%E8%AF%95ajax/url' from origin 'null' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https.
请问怎么怎么解决？
