次のアイコン イメージでカスタム アラート ボックスを作成する必要があります。テキストリンクでやったのですが、テキストリンクの代わりに次のアイコンを入れる方法がわかりません。ここにカスタム アラート ボックス機能を追加しました。誰でもこれを行うのを手伝ってもらえますか。このイメージは、ルート ディレクトリで new-go-next.png という名前になります。

function createCustomAlert(txt,string_url) {
    // shortcut reference to the document object
    d = document;

    // if the modalContainer object already exists in the DOM, bail out.
    if(d.getElementById("modalContainer")) return;

    // create the modalContainer div as a child of the BODY element
    mObj = d.getElementsByTagName("body")[0].appendChild(d.createElement("div"));
    mObj.id = "modalContainer";
     // make sure its as tall as it needs to be to overlay all the content on the page
    mObj.style.height = document.documentElement.scrollHeight + "px";

    // create the DIV that will be the alert 
    alertObj = mObj.appendChild(d.createElement("div"));
    alertObj.id = "alertBox";
    // MSIE doesnt treat position:fixed correctly, so this compensates for positioning the alert
    if(d.all && !window.opera) alertObj.style.top = document.documentElement.scrollTop + "px";
    // center the alert box
    alertObj.style.left = (d.documentElement.scrollWidth - alertObj.offsetWidth)/2 + "px";

    // create an H1 element as the title bar
    h1 = alertObj.appendChild(d.createElement("h1"));
    h1.appendChild(d.createTextNode(ALERT_TITLE));

    // create a paragraph element to contain the txt argument
    msg = alertObj.appendChild(d.createElement("p"));
    msg.innerHTML = txt;

    // create an anchor element to use as the confirmation button.
    btn = alertObj.appendChild(d.createElement("a"));
    btn.id = "closeBtn";
    btn.appendChild(d.createTextNode(ALERT_BUTTON_TEXT));
    btn.href="";
    // set up the onclick event to remove the alert when the anchor is clicked
    btn.onclick = function() { removeCustomAlert(); window.location=string_url;return false; }

要素内に画像 dom 要素を追加するだけです。

var oImg=document.createElement("img");
oImg.setAttribute('src', 'next-to-go');
oImg.setAttribute('alt', 'na');
oImg.setAttribute('height', '60px');
oImg.setAttribute('width', '60px');    

btn.appendChild(oImg);

jsfiddle をチェックしてください。
