创建遮罩层
复制代码 代码如下:
_createCover: function() {
var newMask = document.createElement("div");
newMask.id = this._mark;
newMask.style.position = "absolute";
newMask.style.zIndex = "100";
_scrollWidth = Math.max(document.body.scrollWidth,document.documentElement.scrollWidth);
_scrollHeight = Math.max(document.body.scrollHeight,document.documentElement.scrollHeight);
newMask.style.width = _scrollWidth + "px";
newMask.style.height = _scrollHeight + "px";
newMask.style.top = "0px";
newMask.style.left = "0px";
newMask.style.background = "#000";
newMask.style.filter = "alpha(opacity=50)";
newMask.style.opacity = "0.50";
newMask.style.display = 'none';
document.body.appendChild(newMask);
this._cover = newMask;
}
新建弹出层
复制代码 代码如下:
_createFloater: function(html) {
var newDiv = document.createElement("div");
newDiv.id = this._id;
newDiv.style.position = "absolute";
newDiv.style.zIndex = "9999";
newDivWidth = 400;
newDivHeight = 200;
newDiv.style.width = newDivWidth + "px";
newDiv.style.height = newDivHeight + "px";
newDiv.style.top = (document.body.scrollTop + document.body.clientHeight/2 - newDivHeight/2) + "px";
newDiv.style.left = (document.body.scrollLeft + document.body.clientWidth/2 - newDivWidth/2) + "px";
newDiv.style.padding = "5px";
newDiv.style.display = 'none';
newDiv.innerHTML = html;
document.body.appendChild(newDiv);
this._floater = newDiv;
}
调节弹层位置
复制代码 代码如下:
addjustPosition: function() {
this._floater.style.top = (document.body.scrollTop + document.body.clientHeight/2 - newDivHeight/2) + "px";
this._floater.style.left = (document.body.scrollLeft + document.body.clientWidth/2 - newDivWidth/2) + "px";
}
屏幕滚动事件时调整位置
复制代码 代码如下:
this._fS = BindAsEventListener(this, this.addjustPosition);
addEventHandler(window, "scroll", this._fS);
// 隐藏后需
removeEventHandler(window, "scroll", this._fS);
完整代码
复制代码 代码如下:
var Floater = (function(){
var me = Class.create();
me.prototype = {
initialize: function(options) {
this._fS = BindAsEventListener(this, this.addjustPosition);
this.setOptions(options);

}
},
//遮罩层

newMask.style.position = "absolute";
newMask.style.zIndex = "100";
_scrollWidth = Math.max(document.body.scrollWidth,document.documentElement.scrollWidth);

《魔兽世界》大逃杀!60人新游玩模式《强袭风暴》3月21日上线
暴雪近日发布了《魔兽世界》10.2.6 更新内容,新游玩模式《强袭风暴》即将于3月21 日在亚服上线,届时玩家将前往阿拉希高地展开一场 60 人大逃杀对战。
艾泽拉斯的冒险者已经征服了艾泽拉斯的大地及遥远的彼岸。他们在对抗世界上最致命的敌人时展现出过人的手腕,并且成功阻止终结宇宙等级的威胁。当他们在为即将于《魔兽世界》资料片《地心之战》中来袭的萨拉塔斯势力做战斗准备时,他们还需要在熟悉的阿拉希高地面对一个全新的敌人──那就是彼此。在《巨龙崛起》10.2.6 更新的《强袭风暴》中,玩家将会进入一个全新的海盗主题大逃杀式限时活动,其中包含极高的风险和史诗级的奖励。
《强袭风暴》不是普通的战场,作为一个独立于主游戏之外的活动,玩家可以用大逃杀的风格来体验《魔兽世界》,不分职业、不分装备(除了你在赛局中捡到的),光是技巧和战略的强弱之分就能决定出谁才是能坚持到最后的赢家。本次活动将会开放单人和双人模式,玩家在加入海盗主题的预赛大厅区域前,可以从强袭风暴角色画面新增好友。游玩游戏将可以累计名望轨迹,《巨龙崛起》和《魔兽世界:巫妖王之怒 经典版》的玩家都可以获得奖励。
