如何获取带有换行符的textarea文本？

Question

How to get text of textarea including linebreaks. I need it because I want to send the text by XMLHttpRequest to ASP.NET HttpHandler(.ashx) and keep the initial form of that text. My code:

function BUTTON_CLICK() {
    XMLHttpRequest ajax = new XMLHttpRequest();
    var text = document.getElementById("myTextarea").value;

    ajax.onreadystatechange = function () {
        if (ajax.readyState === 4) {
           document.getElementById("myTextarea").value = ajax.responseText;
        }
    }
    ajax.open("POST", "Code/myHttpHandler.ashx?text=" + text, true);

    ajax.send(null);
}
