JavaScriptのXMLHttpRequestを試してみる

sample.js

/*
 * ブラウザ判別
 */
function getBrowserKind() {
    return navigator.userAgent.toLowerCase();
}


/*
 * 通信
 */
function xmlHttpRequest(method, url) {
    var request = null:
    var browse = getBrowserKind();
    
    if (browse.indexOf('msie') != -1) {
        //Internet Explorer
        request = new ActiveXObject('Microsoft.XMLHTTP');
    }
    else {
        //Other Browser(Google Chrome, Fire Fox, Opera etc...)
        request = new XMLHttpRequest();
    }
    
    request.open(method, url, false);
    request.send();
    
    if (request.status === 200) {
        var elm = document.getElementById('disp');
        elm.innerHTML = request.responseText;
    }
}
