在IE9中滚动很快

标签： javascript html css

我需要在顶部创建一个带有固定标题栏的布局，它将包含不同的控件，并且在它下面有一个大的可滚动svg区域，我将放置不同的svg元素。该区域将在顶部（时间轴）和左侧（位置名称）具有标题。

可滚动区域应该像数据网格视图一样，顶部有列标题，左侧是行标题，但网格内容没有单元格，而是svg（或画布）。

这个jsfiddle应该更好地了解我想要完成的任务（我使用不透明度来看看元素在滚动过程中的行为）：

Javascript代码：

var roomWidth = 150, roomHeight = 50;

            .text(room_name);
        y += roomHeight;
    }
    $('#rooms').css({height:y});
    $('.container').css({height:y + timesHeight});

// generate time slot header text
function getTimeSlots() {

    hscrolled = $(window).scrollLeft();

CSS：

body {
    margin:0;
}

/* header - this is where the toolbar and running text go */
.header {
    width:100%;
    height: 60px;
    background:lightblue;
    border:1px solid green;
    position: fixed;
    margin:0px auto;
    top:0px;
    z-index:10;
}

/* this is where current date and calendar button go */ 
.disp_date {
    width:150px;
    height:50px;
    background: white;
    position:fixed;
    left:0px;
    top:60px;
    z-index:5;
}

/* room list (vertical) */
.rooms {
    fill:yellow;
    position:absolute;
    left:0px;
    top:110px;
    /*border: 3px solid red;*/
    z-index:2;
    width: 150px;
    height:auto;
}

/* actual room rects */
.rect
{
    fill:green;
    stroke:black;
    stroke-width:1;
    opacity:0.5;
}



/* this is time slots header */
.times {
    position:absolute;
    left: 0px; /*150px;*/
    opacity:0.5;
    z-index:1;
}



/* includes tim slots header, canvas (background grid) and cases */     
.container {
    background:pink;
    position:absolute;
    left:150px;
    top:60px;
}

#canv {
    background:yellow;
    opacity:0.5;
    position:relative;
}

.rect2
{
    fill:blue;
    stroke:black;
    stroke-width:1;
    opacity:0.5;
}

问题是它在Firefox或Chrome中运行良好但在IE9中非常跳跃。不幸的是，我必须坚持使用IE9，因为它是一个企业环境。

我想知道我是否可以使用html / ccs实现相同的可滚动布局，或者是否有人可以告诉我如何避免IE9中的抖动滚动。

我只是在学习html / css。任何帮助将不胜感激。

答案 0 :(得分：0)

我对布局和代码进行了更改，它现在也在IE 9中工作。 Here is a link to fixed JSFiddle

HTML：

    <!DOCTYPE html>
<head runat="server">
  <title>Page 1</title>
</head>
<body>
    <form id="form1">
        <header id="toolbar" class="header">
            <span id="scroll"></span>
            <span>This is my header with controls</span>
        </header>

        <div id="date" class="disp_date">bla-bla</div>
        <div id="divtimes">
            <svg id="times" class="times"></svg>
        </div>
        <div id="divrooms">
            <svg id="rooms" class="rooms"></svg>
        </div>

        <div id="scrl">
            <svg id="canv"></svg>

    </form>
</body>

<script type="text/javascript">
   $(document).ready(function () {
      myLoad();
   });
</script>

使用Javascript：

var roomWidth = 150, roomHeight = 50;
var headerHeight = 60;
var timesHeight = 45;
// width of 30 minutes slot
var min30 = 150;
var vscrolled, hscrolled;

var room_count = 30;
var scrollBarWidth = 0;


function setSizes() {
    $('.header').css({ height: headerHeight});
    $('#scrl').css({ left: roomWidth, top: headerHeight + timesHeight });
    $('.disp_date').css({ height: timesHeight, width: roomWidth, top: headerHeight });
    $('#divrooms').css({ width: roomWidth, top: headerHeight + timesHeight });
    $('#divtimes').css({ left: roomWidth, top: headerHeight });
    $('.rooms').css({ width: roomWidth });


}

function myLoad() {

    scrollBarWidth = getScrollbarWidth();
    // reset css sizes
    setSizes();


    var h = $(window).height() - timesHeight - $('.header').height();
    var w = $(window).width() - roomWidth;
    $('#scrl').css({ height: h, width: $(window).width() - roomWidth });
    $('#divrooms').css({ height: h - scrollBarWidth });
    $('#divtimes').css({ width: w - scrollBarWidth });

    $('#scrl').bind('scroll', function (e) { myScroll(); });
    getTimeSlots();
    getRooms();


    drawGrid();

}


// draw time grid
function drawGrid() {

    var canv = d3.select('#canv');
    var y2 = $('#canv').height();
    for (var i = 0; i < 48; i++) {
        canv.append("line")
            .attr("x1", i * min30)
            .attr("y1", 0)
            .attr("x2", i * min30)
            .attr("y2", y2)
            .attr("stroke", "gray")
            .attr("stroke-width",1);
    }

    var x2 = $('#canv').width();
    for (var i = 0; i < room_count; i++) {
        canv.append("line")
            .attr("x1", 0)
            .attr("y1", i * roomHeight)
            .attr("x2", x2)
            .attr("y2", i * roomHeight)
            .attr("stroke", "gray")
            .attr("stroke-width", 1);
    }
