Div Css JS to make pop-up window_html/css_WEB-ITnose

   很久就想做下笔记，把这段时间学到用到的东西都记录下来，以备以后可能重复利用，好啦，开始...

  Div+Css+JS 这三者都是互相影响的，缺一不可。

  首先写好CSS样式，

CSS
#divbg
        {
            width: 100%;
            height: 100%;
            position: absolute;
            z-index: 999;
            top: 0px;
            left: 0px;
            filter: alpha(opacity=50);
            opacity: 0.5;
            background-color: #AAAAAA;
        }
        #diveditcontent
        {
            width: 630px;
            height: 150px;
            position: absolute;
            z-index: 1000;
            background-color: #444444;
        }
        #divheader
        {
            width: 100%;
            height: 25px;
            background-color: #BB5500;
        }

  直接贴上代码了。

Html

JavaScript

        var divheader = document.getElementById("divheader");
        var divbg = document.getElementById("divbg");
        var diveditcontent = document.getElementById("diveditcontent");
        var selects = document.getElementsByTagName("select");
        var divcontent = document.getElementById("divcontent");
        function Show(Key) {

            divbg.style.display = "";
            divbg.style.width = document.body.offsetWidth;  //浏览器宽度(滚动条 clientwidth 边框）
            divbg.style.height = document.body.offsetHeight;

            diveditcontent.style.display = "";
            diveditcontent.style.top = "50px";   //弹出窗口位置
            diveditcontent.style.left = "100px";


            for (var i = 0; i < selects.length; i ) {
                selects[i].style.display = "none";      //遮住下拉框
            }

            divcontent.innerHTML = "";
            //嵌入页

        }
        function Hide() {
            //隐藏窗口
            document.location = location.reload();
            divbg.style.display = "none";
            diveditcontent.style.display = "none";

            for (var i = 0; i < selects.length; i ) {
                selects[i].style.display = "";
            }


        }
        divheader.onmousedown = Down;
        //以下是拉窗口自由移动
        var th;
        var tw;
        function Down(e) {

            var event = window.event || e;
            th = event.clientY - parseInt(diveditcontent.style.top.replace(/px/, ""), 10);
            tw = event.clientX - parseInt(diveditcontent.style.left.replace(/px/, ""), 10);
            document.onmousemove = Move;
            document.onmouseup = Up;
            document.onmouseout = Up;
            function Move(e) {

                var event = window.event || e;
                var top = event.clientY - th;
                var left = event.clientX - tw;
                top = top < 0 ? 0 : top;
                top = top > document.body.offsetHeight - 220 ? document.body.offsetHeight - 220 : top;

                left = left < 0 ? 0 : left;
                left = left > document.body.offsetWidth - 630 ? document.body.offsetWidth - 630 : left;

                diveditcontent.style.top = top   "px";
                diveditcontent.style.left = left   "px";
            }

            function Up() {
                document.onmousemove = null;
            }
        }
