推荐答案

您可以尝试以下..吗?

Can you try the following ..?

function getStatus(url) {
        var request = new XMLHttpRequest();
    request.onreadystatechange = function() {
        if (request.readyState === 4){
            request.status;//this contains the status code
        }
    };
request.open("GET", url , true);
request.send(null);
}
