This article mainly introduces the code analysis of JavaScript to achieve the pop-up effect, which has a good reference value. Let’s take a look at it with the editor below
Rendering:
Without further ado, please look at the code :
每个弹窗的标识 var x =0; var idzt = new Array(); var Window = function(config){ ID不重复 idzt[x] = "zhuti"+x; 弹窗ID 初始化,接收参数 this.config = { width : config.width || 300, 宽度 height : config.height || 200, 高度 buttons : config.buttons || '', 默认无按钮 title : config.title || '标题', 标题 content : config.content || '内容', 内容 isMask : config.isMask == false?false:config.isMask || true, 是否遮罩 isDrag : config.isDrag == false?false:config.isDrag || true, 是否移动 }; 加载弹出窗口 var w = ($(window).width()-this.config.width)/2; var h = ($(window).height()-this.config.height)/2; var nr = "<p class='zhuti' id='"+idzt[x]+"' bs='"+x+"' style='width:"+this.config.width+"px; height:"+this.config.height+"px; left:"+w+"px; top:"+h+"px;'></p>"; $("body").append(nr); 加载弹窗标题 var content ="<p id='title"+x+"' class='title' bs='"+x+"'>"+this.config.title+"<p id='close"+x+"' class='close' bs='"+x+"'>×</p></p>"; 加载弹窗内容 var nrh = this.config.height - 75; content = content+"<p id='content"+x+"' bs='"+x+"' class='content' style='width:100%; height:"+nrh+"px;'>"+this.config.content+"</p>"; 加载按钮 content = content+"<p id='btnx"+x+"' bs='"+x+"' class='btnx'>"+this.config.buttons+"</p>"; 将标题、内容及按钮添加进窗口 $('#'+idzt[x]).html(content); 创建遮罩层 if(this.config.isMask) { var zz = "<p id='zz'></p>"; $("body").append(zz); $("#zz").css('display','block'); } 最大最小限制,以免移动到页面外 var maxX = $(window).width()-this.config.width; var maxY = $(window).height()-this.config.height; var minX = 0, minY = 0; 窗口移动 if(this.config.isDrag) { 鼠标移动弹出窗 $(".title").bind("mousedown",function(e){ var n = $(this).attr("bs"); 取标识 使选中的到最上层 $(".zhuti").css("z-index",3); $('#'+idzt[n]).css("z-index",4); 取初始坐标 var endX = 0, 移动后X坐标 endY = 0, 移动后Y坐标 startX = parseInt($('#'+idzt[n]).css("left")), 弹出层的初始X坐标 startY = parseInt($('#'+idzt[n]).css("top")), 弹出层的初始Y坐标 downX = e.clientX, 鼠标按下时,鼠标的X坐标 downY = e.clientY; 鼠标按下时,鼠标的Y坐标 绑定鼠标移动事件 $("body").bind("mousemove",function(es){ endX = es.clientX - downX + startX; X坐标移动 endY = es.clientY - downY + startY; Y坐标移动 最大最小限制 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 }
