Windows Flash prototype Microsoft HTML

1.设置窗口关闭方法委托

System.Gadget.onSettingsClosing = settingsClosing;

function settingsClosing(event)
{
    if(event.closeAction == event.Action.commit)
    {
        saveSettings();
    }
    else if (event.closeAction == event.Action.cancel)
    {
    }
    event.cancel = false;
}

2.写入系统设置

this.rssFeedPath = System.Gadget.Settings.read("rssFeedPath");

3.读取系统设置

System.Gadget.Settings.write("rssFeedPath", _feedPath);

4.参数初始化

function clearViewElements()
{
    positionNumbers.innerText = "";
    for(i=0; i < 4; i++)
    {
        if ( g_viewElements !== null )
        {
            g_viewElements.FeedItems[i].innerHTML = "";
            g_viewElements.FeedItems[i].href = "";
            g_viewElements.FeedItems[i].innerText = "";
            g_viewElements.FeedItems[i].setAttribute("name", "");
            g_viewElements.FeedItems[i].setAttribute("localId", "");
        }

        eval("FeedItemName"+i).innerHTML = "";
        eval("FeedItemName"+i).style.backgroundColor = "";
        eval("FeedItemName"+i).innerText = "";
        eval("FeedItemName"+i).setAttribute("title","");

        eval("FeedItemDate"+i).innerHTML = "";
        eval("FeedItemDate"+i).style.backgroundColor = "";
        eval("FeedItemDate"+i).innerText = "";
        eval("FeedItemDate"+i).setAttribute("title","");

        eval("FeedItemLink"+i).style.textOverflow = "";
        eval("FeedItemLink"+i).style.overflow = "";
        eval("FeedItemLink"+i).style.whiteSpace = "";
        eval("FeedItemLink"+i).style.width = "0px";
    }
}

5.调试输出

System.Debug.outputString("Start Polling : Pull feeds queued up in bursts"); //DEBUG CODE

6.启动一个定时刷新

function startTimer()
{
    if(g_timerFlag)
    {
        stopTimer();
        g_timer = setInterval(setNextViewItems, g_timerMilliSecs);
    }
}

setTimeout(loadData, 1000);

7.停止一个定时刷新

function stopTimer()
{
    if(g_timerFlag)
    {
        clearInterval(g_timer);
    }
}

8.指定设置页面文件

System.Gadget.settingsUI = "settings.html";

9.打开Flyout 窗口

System.Gadget.Flyout.show = true;

10.键盘按键捕获

function keyNavigate()
{
switch(event.keyCode)
{

        case 38:
        case 104:
            setPreviousViewItems();
            break;
        case 40:
        case 98:
            setNextViewItems();
            break;
        case 32:
        case 13:
            if(event.srcElement.id == "buttonLeftNarrator")
            {
                setPreviousViewItems();
            }
            else if(event.srcElement.id == "buttonRightNarrator")
            {
                setNextViewItems();
            }
            break;
        case 27:
            hideFlyout();
            break;
    }
}

11.鼠标滑轮

function mouseWheeNavigate()
{
if( g_returnFeed == null )
return;

12 获取Flyout 文件对象，并设置内容

var flyoutDiv = System.Gadget.Flyout.document;

flyoutDiv.getElementById("flyoutTitleLink").innerText = tempTitle;
                flyoutDiv.getElementById("flyoutTitleLink").href = checkHref(g_feedURL);
                flyoutDiv.getElementById("flyoutTitleLink").setAttribute("title", tempTitle);
                flyoutDiv.getElementById("flyoutTitleLink").style.textOverflow = "ellipsis";
                flyoutDiv.getElementById("flyoutTitleLink").style.overflow = "hidden";
                flyoutDiv.getElementById("flyoutTitleLink").style.whiteSpace = "nowrap";

13.窗口停靠

if(!System.Gadget.docked)
        {
            var backgroundToLoad = "url(images/item_hover_floating.png)";
        }

14. Flyout 窗口文件设置

System.Gadget.Flyout.file = "flyout.html";

15. 显示设置页面的方法

System.Gadget.onShowSettings = loadSettings;

16. Gadget 是否可见

System.Gadget.visibilityChanged = checkVisibility;

function checkVisibility()
{
    isVisible = System.Gadget.visible;
    if (!isVisible)
    {
        stopTimer();
    }
    if(isVisible)
    {
        startTimer();
    }
}

17. 初始化配置集合

System.Gadget.settingsUI = "settings.htm";                              // 设置Setting 页面
System.Gadget.onShowSettings = procSettingsShowEvent;                   // set settings onshow method
System.Gadget.onSettingsClosed = procSettingsClosedEvent;               // set settings onclosed method

// init dock/undock event methods
System.Gadget.onUndock = procUndockEvent; // set gadget onundock method
System.Gadget.onDock = procDockEvent; // set gadget ondock method

// init flyout event methods
System.Gadget.Flyout.file = "flyout.htm";                               // set flyout page
System.Gadget.Flyout.onShow = procFlyoutShowEvent;                      // set gadget flyout show event
System.Gadget.Flyout.onHide = procFlyoutHideEvent;         // set gadget flyout hide event

18. 简化开发的最好方法，是下载现有的Gadget，修改其内容实用，下面是地址。

19. 如果Gadget中嵌入Flash

1.要将投影效果去掉

2. 添加透明属性

if(typeof infosoftglobal == "undefined") var infosoftglobal = new Object();
if(typeof infosoftglobal.FusionChartsUtil == "undefined") infosoftglobal.FusionChartsUtil = new Object();

var FusionCharts = infosoftglobal.FusionCharts;

this.addParam('Wmode', 'transparent');

FusionCharts.prototype = {
    setAttribute: function(name, value){
        this.attributes[name] = value;
    },
    getAttribute: function(name){
        return this.attributes[name];
    },
    addParam: function(name, value){
        this.params[name] = value;
    },
    getParams: function(){
        return this.params;
    }

}

           var params = this.getParams();
            for(var key in params) {
             swfNode += '<param name="'+ key +'" value="'+ params[key] +'" />';
            }

3.使用一个透明背景的Png 图片最背景，达到背景透明的效果，并设置四边框为0，如下

      function Initialize() {
            try {
                System.Gadget.settingsUI = "options.html";
            } catch (e) { };

}

4.在重复加载一个Flash，数据源的时候，会有缓存的问题，简单的解决办法就是用时间拼装不重复的访问字符串，已达到每次访问都不一样的目的，避免缓存

function updateChart(DOMId) {

            var strURL = "http://localhost:9999/Chart/Gallery/Data/Angular5.xml?time=a" + Date.prototype.Format("yyyyMMddhhmmss");
            var myChart = new FusionCharts("http://localhost:9999/Chart/Charts/AngularGauge.swf", "myChartId", "200", "200", "0", "0");
            myChart.setDataURL(strURL);
            myChart.render("chartdiv");
        }
