This article mainly explains "how to achieve pop-up window with jQuery". Interested friends may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "how to achieve a pop-up window with jQuery".

First write the code that references the file:

/ / the logo of each pop-up window var x = 0 Bing var idzt = new Array (); var Window = function (config) {/ / ID do not repeat idzt [x] = "zhuti" + x / / pop-up window ID / / initialize Receive parameter this.config = {width: config.width | | 300, / / width height: config.height | | 200, / / height buttons: config.buttons | |', / / default no button title: config.title | | 'title', / / title content: config.content | | 'content', / / content isMask: config.isMask = = false?false:config.isMask | | true, / / whether to mask isDrag: config.isDrag = = false?false:config.isDrag | | true | / / whether to move} / / load pop-up window var w = ($(window). Width ()-this.config.width) / 2; var h = ($(window). Height ()-this.config.height) / 2; var nr = ""; $("body") .append (nr); / / load pop-up window title var content = "" + this.config.title+ "×"; / / load pop-up window content var nrh = this.config.height-75; content = content+ "+ this.config.content+" / / load button content = content+ "" + this.config.buttons+ "; / / add title, content, and buttons to window $('#'+ idzt [x]) .html (content); / / create mask layer if (this.config.isMask) {var zz ="; $("body") .append (zz); $("# zz"). Css ('display','block') } / / maximum and minimum limit to avoid moving off the page var maxX = $(window). Width ()-this.config.width; var maxY = $(window). Height ()-this.config.height; var minX = 0, minY = 0; / / window movement if (this.config.isDrag) {/ / mouse movement pop-up window $(".title") .bind ("mousedown", function (e) {var n = $(this) .attr ("bs") / / take the logo / / make the selected one go to the top $(".zhuti") .css ("z-index", 3); $('#'+ idzt [n]) .css ("z-index", 4) / / take the initial coordinate var endX = 0, / / move the X coordinate endY = 0, / / move the Y coordinate startX = parseInt ($('#'+ idzt [n]) .css ("left")), / / the initial X coordinate of the ejection layer startY = parseInt ($('#'+ idzt [n]) .css ("top")), / / the initial Y coordinate of the pop-up layer downX = e.clientX / / when the mouse is pressed The X coordinate of the mouse downY = e.clientY / / when the mouse is pressed, the Y coordinates of the mouse / / bind the mouse movement event $("body"). Bind ("mousemove", function (es) {endX = es.clientX-downX + startX; / / X coordinate movement endY = es.clientY-downY + startY; / / Y coordinate movement / / maximum and minimum limit if (endX > maxX) {endX = maxX } else if (endX

< 0) { endX = 0; } if(endY >

MaxY) {endY = maxY;} else if (endY

< 0) { endY = 0; } $('#'+idzt[n]).css("top",endY+"px"); $('#'+idzt[n]).css("left",endX+"px"); window.getSelection ? window.getSelection().removeAllRanges():document.selection.empty(); //取消选中文本 }); }); //鼠标按键抬起，释放移动事件 $("body").bind("mouseup",function(){ $("body").unbind("mousemove"); }); } //关闭窗口 $(".close").click(function(){ var m = this.getAttribute("bs"); //找标识 $('#'+idzt[m]).remove(); //移除弹窗 $('#zz').remove(); //移除遮罩 }) x++; //标识增加 } 这个JS文件把弹出窗口的内容，样式，位置，按钮，以及遮罩层都做了处理，在引用前好好看看里面的代码，最好都能弄懂，里面也做了详细的注释，希望可以帮的你。 下面是CSS样式表： .zhuti{ position:absolute; z-index:3; font-size:14px; border-radius:5px; box-shadow:0 0 5px white; overflow:hidden; color:#333;}.title{ background-color:#3498db; vertical-align:middle; height:35px; width:100%; line-height:35px; text-indent:1em;}.close{ float:right; width:35px; height:35px; font-weight:bold; line-height:35px; vertical-align:middle; color:white; font-size:18px; }.close:hover{ cursor:pointer;}.content{ text-indent:1em; padding-top:10px;}.btnx{ height:30px; width:100%; text-indent:1em;}.btn{ height:28px; width:80px; float:left; margin-left:20px; color:#333;}#zz{ width:100%; height:100%; opacity:0.15; display:none; background-color:#ccc; z-index:2; position:absolute; top:0px; left:0px;} 这个样式表把每个标签和所需要的样式都写好了，这样就能节省主要页面的代码量，并且让主页面看起来非常的整齐，如果要改，只需要在CSS样式表中修改即可，注意：不管要引用什么文件，必须把Jquery文件放在最前面！！！ 下面是主页面代码： 无标题文档*{ margin: 0px auto;}$(document).ready(function(e) { $('#btntc').click(function(){ var html = "这是测试的弹窗"; var button =""; var win = new Window({ width : 400, //宽度 height : 300, //高度 title : '测试弹窗', //标题 content : html, //内容 isMask : false, //是否遮罩 buttons : button, //按钮 isDrag:true, //是否移动 }); })}); 同样的，主页面里面也加了详细的注释，这样便于日后的理解，希望可以帮的自己和大家。让我们看看效果吧：

The effect after clicking the pop-up window:

We can see that each pop-up window can be moved, and countless pop-up windows can be popped up. If you change the mask layer to true, there will be no second pop-up window.

Be sure to remember the usefulness of the mask layer, so that you can avoid a lot of BUG if you want to reference pop-up windows must be tested before use, in case of problems, remember!
