flot

当我在FF中运行这个小工具时,图形绘制得很好。但当我从小工具运行它时,它不起作用。我知道JQuery代码正在工作,因为我可以使用它来更改html、样式等。

所以问题出在牙线部分。

有什么想法吗?思想?

html代码:

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
    <script language="javascript" type="text/javascript" src="js/jquery.js"></script>
    <script language="javascript" type="text/javascript" src="js/jquery.flot.js"></script>
    <script language="javascript" type="text/javascript" src="js/Docked.js" ></script>
    <link href="css/Docked.css" rel="stylesheet" type="text/css" />
</head>
<body onload="CheckDockState();">
    <g:background id="imgBackground">
    <div id="gadgetContent">
    </div>
    </g:background>
</body>
</html>

// Gadget width and height.
var gadgetWidth = 800;
var gadgetHeight = 800;

// Amount to scale gadget when docked or undocked.
var scaleDocked = 1;
var scaleUndocked = 2;

// Amount of time desired to perform transition (in seconds).
var timeTransition = 2;

// Declare the dock and undock event handlers.
try
{
    System.Gadget.onDock = CheckDockState;
    System.Gadget.onUndock = CheckDockState;
}
catch(err){}

// --------------------------------------------------------------------
// Check the gadget dock state; set the gadget style.
// --------------------------------------------------------------------
function CheckDockState()
{
    try
    {
        var oBackground = document.getElementById("imgBackground");
        System.Gadget.beginTransition();

        var oBody = document.body.style;
        if (System.Gadget.docked)
        {
            oBody.width = gadgetWidth*scaleDocked;
            oBody.height = gadgetHeight*scaleDocked;

            oBackground.src = "../images/bg_docked.png";

            //txtDocked.innerText = 'Docked';
            gadgetContent.innerHTML = 'Docked <button onclick="ShowChart();">press me</button>';
            gadgetContent.className = 'gadgetDocked';
        }
        else
        {
            oBody.width = gadgetWidth*scaleUndocked;
            oBody.height = gadgetHeight*scaleUndocked;  

            oBackground.src = "../images/bg_undocked.png";

            //txtDocked.innerText = 'Undocked';
            gadgetContent.innerHTML = 'Docked <button onclick="ShowChart();">press me</button>';
            gadgetContent.className = 'gadgetUndocked';
        }
        System.Gadget.endTransition(System.Gadget.TransitionType.morph, timeTransition);
    }
    catch(err)
    {
        // in a browser, some variables are different/missing then in the gadget, so i'm using this
        gadgetContent.innerHTML = 'Docked <button onclick="ShowChart();">press me</button>';
    }
}

function ShowChart()
{
    var d1 = [];
    for (var i = 0; i < 14; i += 0.5)
        d1.push([i, Math.sin(i)]);

    var d2 = [[0, 3], [4, 8], [8, 5], [9, 13]];

    // a null signifies separate line segments
    var d3 = [[0, 12], [7, 12], null, [7, 2.5], [12, 2.5]];

    // just to see the jquery works
    $("#gadgetContent").width(200);
    $("#gadgetContent").height(200);

    jQuery.plot($("#gadgetContent"), [ d1, d2, d3 ]);
}

IE不支持 <canvas> 元素,但flot支持 excanvas

<script language="javascript" type="text/javascript" 
    src="js/excanvas.min.js"></script>

另外,不要把你的 g:background

<g:background id="imgBackground"></g:background>
<div id="gadgetContent"> 
</div>

附加说明,仅供参考- beginTransition() 和 endTransition() 已弃用,在Windows 7中不会执行任何操作。那是因为变形看起来有点粗糙。你可以把它留给Vista用户,但我只是想让你知道。

我不知道他们的交互式图表API如何处理Windows小工具。
