HTML隐藏alert和confirm弹出框的IP

做了一个供移动端调用的html，测试时发现confirm提示时显示ip。

解决方法：

  在js的最前面加上如下代码即可：

//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); 

    } 

}
