/*重寫alert方法*/window.alert = function(str){var alertFram = document.createElement("DIV");alertFram.id="alertFram";alertFram.style.position = "fixed";alertFram.style.width = "100%";alertFram.style.height = "100%";alertFram.style.top = "0";alertFram.style.textAlign = "center";alertFram.style.lineHeight = "150px";alertFram.style.zIndex = "300";alertFram.style.backgroundColor="rgba(0, 0, 0, 0.58)";alertFram.style.fontSize="12px";strHtml = '<ul class="alert_ul">';strHtml += '<li class="alert_content">'+str+'</li>';strHtml += '<li class="alert_btn-wrap"><a type="button" value="確定" οnclick="doOk()" class="alert_btn">確定</a></li>';strHtml += '</ul>';alertFram.innerHTML = strHtml;document.body.appendChild(alertFram);this.doOk = function(){alertFram.style.display = "none";}}

　　css渲染

.alert_ul{list-style:none;margin:0px;padding:0px;width:70%;margin: auto;margin-top: 53%;} .alert_title{background:#F2F2F2;text-align:left;padding-left:20px;line-height:60px;border:1px solid #999;} .alert_content{background:#fff;text-align:center;height:80px;line-height:80px;} .alert_btn-wrap{background:#fff;text-align:center;height:30px;line-height:18px;} .alert_btn{cursor:pointer;color:#2bd00f;}
