z-index解決彈出層遮罩層覆蓋子div不能顯示輸出的問題

// 添加以下代碼來進行測試：// Ajax 發生錯誤，就會執行$('body').ajaxError(function(e, xhr, setting, text){ // e - event 事件 // xhr - xmlHttPRequest 對象 // setting - ajax 設置 // text - 錯誤信息 alert(text);});// ajax 完成后，就會執行$('body').ajaxComplete(function(){ alert('complete'); // ajax 請求完成就會執行})$.ajax({ url: '/sms/AjaxSMS.ashx', type: "POST", data: "txtcontent=" + content+"&txtback=" + content2+"", async: false, success: function(data) { if (data == "成功" || data == "[object XMLDocument]") { IsAddSuffix(hdtatolSMS, arr, mob); //后綴名 confirm("您本次發送短信數量為：" + (parseInt(hdtatolSMS) * arr.length) + ",確認發送嗎？"); } else { alert(content + "可能涉及廣告類、營銷類等系統不允許發送的內容，請修改后再發送。"); } }, error: function(a) { alert(a.responseText); } });//添加后綴判斷function IsAddSuffix(data, arr, mob) { var txtBack = document.getElementById("ctl00_ContentPlaceHolder1_txtBack").value; if (txtBack == "") { confirm("后綴為空，您本次發送短信數量為：" + (parseInt(data) * arr.length) + ",確認發送嗎？"); } else { if (txtBack.length + mob.value.length > maxnums - 1) { alert("內容加上后綴(系統自動補充空格)長度不能起過" + maxnums + "個字符，請重新輸入!"); } }}

<script type="text/javascript" language="Javascript"> $(function() { //彈出提示框（快旅新域名） var isRead = getHCookie('warnTips'); if (isRead == null) { popupDiv('pop-div'); } function popupDiv(div_id) { var div_obj = $("#" + div_id); var windowWidth = document.documentElement.clientWidth; var windowHeight = document.documentElement.clientHeight; var popupHeight = div_obj.height(); var popupWidth = div_obj.width(); //添加并顯示遮罩層 $("<div id='mask'></div>").addClass("mask") .width(windowWidth * 0.99) .height(windowHeight * 0.99) //.CSS({ "position": "absolute", "background": "#CCCCCC", "left": "0px", "top": "0px", "zIndex": "1", "filter": "Alpha(Opacity=60)" })遮蓋層 .css({ "position": "absolute" }) .click(function() { hideDiv(div_id); }) .appendTo("body") .fadeIn(200); div_obj.css({ "position": "absolute" }) .animate({ left: windowWidth / 2 - popupWidth / 2, top: windowHeight / 2 - popupHeight / 2, opacity: "show" }, "slow"); } }); function hideDiv(div_id) { $("#mask").remove(); $("#" + div_id).animate({ left: 0, top: 0, opacity: "hide" }, "slow"); //記錄cookie SetHCookie('warnTips', 'read'); //window.parent.del(); } function SetHCookie(name, value)//兩個參數，一個是cookie的名稱，一個是值 { var Days = 1; //此 cookie 將被保存 1 天 var exp = new Date(); exp.setTime(exp.getTime() + Days * 24 * 60 * 60 * 1000); document.cookie = name + "=" + escape(value) + ";expires=" + exp.toGMTString(); } function getHCookie(name)//取cookies函數 { var arr = document.cookie.match(new RegExp("(^| )" + name + "=([^;]*)(;|$)")); if (arr != null) return unescape(arr[2]); return null; } function delHCookie(name)//刪除cookie { var exp = new Date(); exp.setTime(exp.getTime() - 1); var cval = getHCookie(name); if (cval != null) document.cookie = name + "=" + cval + ";expires=" + exp.toGMTString(); } </script>

z-index遮罩層的光標輸入方案：遮罩層問題。必須設置z-index，必須小于父div元素的數值，不然會失去效果。
