PHPプログラミング実戦15-6

    


Ajax grabbed plain text:

 

    var xhr = new XMLHttpRequest();
    xhr.open("GET", "animals.xml", true);
    xhr.onreadystatechange = function () {
        //console.log(xhr.readyState);
        if (xhr.readyState == 4) {
            var message = "";
            //console.log(xhr.status);
            if (xhr.status = 200) {
                //           
                console.log(xhr.responseText);
                message = "<pre>" + xhr.responseText + "</pre>";
            }
            else {
                message = "An error has occured making the request";
            }
            //xml           ,       
            document.getElementById("generated_content").innerHTML = message;
        }
    }
    xhr.send(null);

GetElementById
Element単数、結果一意
