JSON和AJAX
<script type="text/javascript"> $(document).ready(function(e) { var a = { code:"p001", name:"张三", shuzu:new Array(1,2,3,4), json:{aa:"aa",bb:"bb"}, age:18 }; alert(a.json.bb);----弹出窗口bb
</script>
弹出窗口练习：
<body style="background-color:#999"> <div style="200px; margin-top:10px"><input type="button" value="弹出窗口" id="btntc" style="100px; height:30px; font-size:18px;" /></div> <div id="tc"></div> </body> <script type="text/javascript"> $(document).ready(function(e) { $('#btntc').click(function(){ var html = "<div style='color:red'>这是测试的弹窗</div>"; var button ="<input type='button' value='确定' /><input type='button' value='取消' />"; var win = new Window({ width : 700, //宽度 height : 500, //高度 title : '弹窗', //标题 content : html, //内容 isMask : false, //是否遮罩 buttons : button, //按钮 isDrag:true, }); }) }); </script>
// 每个弹窗的标识 var x =0; var idzt = new Array(); var Window = function(config){ //ID不重复 idzt[x] = "zhuti"+x; //弹窗ID //初始化，接收参数 this.config = { width : config.width || 300, //宽度 height : config.height || 200, //高度 buttons : config.buttons || '', //默认无按钮 title : config.title || '标题', //标题 content : config.content || '内容', //内容 isMask : config.isMask == false?false:config.isMask || true, //是否遮罩 isDrag : config.isDrag == false?false:config.isDrag || true, //是否移动 }; //加载弹出窗口 var w = ($(window).width()-this.config.width)/2; var h = ($(window).height()-this.config.height)/2; var nr = "<div class='zhuti' id='"+idzt[x]+"' bs='"+x+"' style='"+this.config.width+"px; height:"+this.config.height+"px; background-color:white; left:"+w+"px; top:"+h+"px;'></div>"; $("body").append(nr); //加载弹窗标题 var content ="<div id='title"+x+"' class='title' bs='"+x+"'>"+this.config.title+"<div id='close"+x+"' class='close' bs='"+x+"'>×</div></div>"; //加载弹窗内容 var nrh = this.config.height - 75; content = content+"<div id='content"+x+"' bs='"+x+"' class='content' style='100%; height:"+nrh+"px;'>"+this.config.content+"</div>"; //加载按钮 content = content+"<div id='btnx"+x+"' bs='"+x+"' class='btnx'>"+this.config.buttons+"</div>"; //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 = "<div id='zz'></div>"; $("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.getAttribute("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 }
