이미지 확인 버튼이있는 자바 스크립트 맞춤 알림 상자

Question

다음 아이콘 이미지로 맞춤 알림 상자를 만들어야합니다. 나는 텍스트 링크로했는데 텍스트 링크 대신에 다음 아이콘을 넣는 법을 모른다. 내 맞춤 알림 상자 기능을 여기에 추가했습니다. 누구든지이 일을 도울 수 있습니다. 이 이미지 이름은 루트 디렉토리의 new-go-next.png입니다.

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; }

     btn.onclick = function() { removeCustomAlert(); window.location = string_url; return false; } 


    }

단지 요소 내에 화상 DOM 요소를 추가한다. 위에서 언급 한 바와 같이

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); 

Check out the jsfiddle.
