在前端页面中加入下面js代码即可(作用 重写alert方法)

<script>
//重写alert
window.alert = function(name){
    var iframe = document.createElement("IFRAME");
    iframe.style.display="none";
    iframe.setAttribute("src", 'data:text/plain,');
    document.documentElement.appendChild(iframe);
    window.frames[0].window.alert(name);
    iframe.parentNode.removeChild(iframe);
}
//重写confirm 不显示ip地址  
var wConfirm = window.confirm;  
window.confirm = function (message) {  
    try {  
        var iframe = document.createElement("IFRAME");  
        iframe.style.display = "none";  
        iframe.setAttribute("src", 'data:text/plain,');  
        document.documentElement.appendChild(iframe);  
        var alertFrame = window.frames[0];  
        var iwindow = alertFrame.window;  
        if (iwindow == undefined) {  
            iwindow = alertFrame.contentWindow;  
        }  
        var result = iwindow.confirm(message);  
        iframe.parentNode.removeChild(iframe);  
        return result;  
    }  
    catch (exc) {  
        return wConfirm(message);  
    }  
</script>

当然啦,也可使用下面的js代码来自定义我们的alert弹框

<script>
window.alert = function(str) 
{ 
var shield = document.createElement("DIV"); 
shield.id = "shield"; 
shield.style.position = "absolute"; 
shield.style.left = "0px"; 
shield.style.top = "0px"; 
shield.style.width = "100%"; 
shield.style.height = document.body.scrollHeight+"px"; 
//弹出对话框时的背景颜色 
shield.style.background = "#fff"; 
shield.style.textAlign = "center"; 
shield.style.zIndex = "25"; 
//背景透明 IE有效 
//shield.style.filter = "alpha(opacity=0)"; 
var alertFram = document.createElement("DIV"); 
alertFram.id="alertFram"; 
alertFram.style.position = "absolute"; 
alertFram.style.left = "50%"; 
alertFram.style.top = "50%"; 
alertFram.style.marginLeft = "-225px"; 
alertFram.style.marginTop = "-75px"; 
alertFram.style.width = "450px"; 
alertFram.style.height = "150px"; 
alertFram.style.background = "#ff0000"; 
alertFram.style.textAlign = "center"; 
alertFram.style.lineHeight = "150px"; 
alertFram.style.zIndex = "300"; 
strHtml = "<ul style=\"list-style:none;margin:0px;padding:0px;width:100%\">\n"; 
strHtml += " <li style=\"background:#DD828D;text-align:left;padding-left:20px;font-size:14px;font-weight:bold;height:25px;line-height:25px;border:1px solid #F9CADE;\">[自定义提示]</li>\n"; 
strHtml += " <li style=\"background:#fff;text-align:center;font-size:12px;height:120px;line-height:120px;border-left:1px solid #F9CADE;border-right:1px solid #F9CADE;\">"+str+"</li>\n"; 
strHtml += " <li style=\"background:#FDEEF4;text-align:center;font-weight:bold;height:25px;line-height:25px; border:1px solid #F9CADE;\"><input type=\"button\" value=\"确 定\" οnclick=\"doOk()\" /></li>\n"; 
strHtml += "</ul>\n"; 
alertFram.innerHTML = strHtml; 
document.body.appendChild(alertFram); 
document.body.appendChild(shield); 
var ad = setInterval("doAlpha()",5); 
this.doOk = function(){ 
alertFram.style.display = "none"; 
shield.style.display = "none"; 
} 
alertFram.focus(); 
document.body.onselectstart = function(){return false;}; 
}
</script>
