jquery 锁定弹出层实现代码_jquery

基于jquery的锁定弹出层
这个东西也是随手总结出来的,引用了一些js框架jquery的方法。
div遮盖其他控件的方法参考了 对于需要遮盖flash的,请将flash控件的WMode变量值设置为Transparent
使用方法:
复制代码 代码如下:




//配置模块
var moduleEvent = [{"idName":"close" , "eventName":"click" , "doMethod":"CLOSE_DIV"},{"idObj":window,"eventName":"resize" , "doMethod":"RESIZE_WINDOW"}];
qihoo_effect_maskDiv.showMaskDiv("your div id" , moduleEvent); //请把div的display设置为none。
*******************************************************
effect/maskDiv.js
复制代码 代码如下:

var qihoo_effect_maskDiv = {
_module : {},
_css : {},
_instance : "" ,
_event : {"CLOSE_WINDOW" : function() { window.close(); } , "CLOSE_DIV" : function(){qihoo_effect_maskDiv.closeDiv();} , "RESIZE_WINDOW" : function(){qihoo_effect_maskDiv.resizeWindow();} },
_isIe : eval("false;/*@cc_on@if(@\x5fwin32)isMSIE=true@end@*/") ,
init : function (){
if (this._instance){
return this._instance;
}
this.appendBackGroundDiv();
this._instance = this;
return this._instance;
},
appendBackGroundDiv : function (){
this._module.backGroundDiv = $("");
this._module.backGroundDiv.appendTo("body");
this._css.mask = { "background-color":"#000" , "position":"absolute", "-moz-opacity": "0.75" , "filter":"alpha(opacity=75)","z-index":5 , "width" : document.body.clientWidth+100 , "height" : document.body.clientHeight+300 , "top" : "0px" , "left":"0px" , "display" : "none"};
this._module.backGroundDiv.css(this._css.mask);
this._module.coverIframe = $("");
this._css.normalIframe = {'position':'absolute','left':'-1000px','top':'-1000px','z-index':7};
this._module.coverIframe.css(this._css.normalIframe);
this._module.coverIframe.appendTo("body");
},
showMaskDiv : function (showDivId , moduleEvent, position ){
instance = this;
if (this._isIe){
if(document.readyState != "complete"){
setTimeout(function(){instance.showMaskDiv(showDivId , moduleEvent , position);} , 100);
return false;
}
}
if ("" == this._instance){
this.init();
}
this._module.showDiv = $("#"+showDivId);
if (typeof position == 'undefined'){
this._css.coverIframe = {'position':'absolute','top':parseInt(screen.height/4+document.documentElement.scrollTop)+"px",'left':parseInt(screen.width/4+document.documentElement.scrollLeft)+"px",'zIndex':7};
this._css.coverd = {"zIndex" : 10 , "position" : "absolute" ,"width":"400px" , "height":"240px" ,"top": parseInt(screen.height/4+document.documentElement.scrollTop)+"px", "left":parseInt(screen.width/4+document.documentElement.scrollLeft)+"px"};
}
else{
this._css.coverIframe = {'position':'absolute',"height" : position.height, "width":position.width , "top": position.top , "left":position.left,'zIndex':7};
this._css.coverd = {"zIndex" : 10 , "position" : "absolute" , "height" : position.height, "width":position.width , "top": position.top , "left":position.left};
}
for (var i in moduleEvent){
if (typeof moduleEvent[i].idName != "undefined") {
$("#"+moduleEvent[i].idName).bind(moduleEvent[i].eventName , this._event[moduleEvent[i].doMethod]);
}
if (typeof moduleEvent[i].idObj != "undefined") {
$(moduleEvent[i].idObj).bind(moduleEvent[i].eventName , this._event[moduleEvent[i].doMethod]);
}
}
this._module.backGroundDiv.show();
showDivFront = this._module.showDiv;
cssParam = this._css;
coveredIframe = this._module.coverIframe;
this._module.backGroundDiv.animate({opacity:0.75},"normal" , function(){coveredIframe.css(cssParam.coverIframe);showDivFront.show();});
this._module.showDiv.css(this._css.coverd);
},
resizeWindow : function (){
this._css.mask = { "background-color":"#000" , "position":"absolute", "-moz-opacity": "0.75" , "opacity":"0.75" , "filter":"alpha(opacity=75)","zIndex":5 , "width" : document.body.clientWidth+100, "height" : document.body.clientHeight+300 , "top" : "0px" , "left":"0px"};
this._module.backGroundDiv.css(this._css.mask);
},
closeDiv : function (){
this._module.coverIframe.css(this._css.normalIframe);
this._module.showDiv.hide();
hidebBackGroundDiv = this._module.backGroundDiv;
this._module.backGroundDiv.animate({opacity:0},"normal", function(){hidebBackGroundDiv.hide();});
}
};

看评论所言,加了一点用法:

这里是一个不引入jquery框架的实现同样效果的程序。

引入文件


配置事件

注:idName是绑定事件的html组件的id,idObj是html控件变量
配置初始位置(可选步骤)
显示遮罩层
qihoo_effect_maskDiv.showMaskDiv(divId, moduleEvent , position);或者qihoo_effect_maskDiv.showMaskDiv(divId, moduleEvent );
隐去遮罩层
qihoo_effect_maskDiv.closeDiv();

js实现的遮盖层的定义:
经常遇到要弹出一个悬浮层,鼠标的事件只能在本层上有效,底层会失效。能用的做 法是在悬浮层和底层之间在加一个遮盖层,遮盖住整个浏览器,这样就不能点击底层的任何东西了。
复制代码 代码如下:

var w = Math.max(document.documentElement.scrollWidth, document.documentElement.clientWidth) + "px"; //获取宽
var h = Math.max(document.documentElement.scrollHeight, document.documentElement.clientHeight) + "px"; //获取高
//定义一个透明背景层
var gb = $("").attr("id","gb")
.css({top:"0",left:"0",zIndex:"2",position:"absolute",filter:"alpha(opacity=0)",background:"#fff"})
.css("width",w).css("height",h)

其实说明最主要还是说明一下背景层的CSS定义。首先要使top和left有效,就要设置 position:absolute。filter:"alpha(opacity=0)设置透明度,数值0-100,0表示完全透明,100表示不透明。background设置背景层的颜色。zIndex的值只要比底层的高,比弹出层的低就行了。(zIndex的值越大表示越在上层)。好了,基本就是这样吧!
