我基本上来自'c语言'背景，并且对脚本没有任何想法。

我想要实现的是：

SwapView 中有一个条形图。现在每次当用户访问这个 SwapView 时，我想用新的数据集重新加载 Bargrap。假设我有一个全局数据，即：window.myvalues。我需要捕获哪个事件，以及如何做到这一点？

好心劝告。这是我从 dojo 网站使用的示例。

 <div id="barview" data-dojo-type="dojox.mobile.SwapView">



        <script>
            function mybarchartNode(){


                require([
                         // Require the basic chart class
                         "dojox/charting/Chart",

                         // Require the theme of our choosing
                         "dojox/charting/themes/MiamiNice",

                         //  We want to plot Columns
                         "dojox/charting/plot2d/Columns",

                         // Require the highlighter
                         "dojox/charting/action2d/Highlight",

                         //  We want to use Markers
                         "dojox/charting/plot2d/Markers",

                         //  We'll use default x/y axes
                         "dojox/charting/axis2d/Default",

                         // Wait until the DOM is ready
                         "dojo/domReady!"
                         ], function(Chart, theme, ColumnsPlot, Highlight) {


                        console.log ("Data set in the bar graph ");
                        console.log (window.myDatas);
                        // Define the data
                        var chartData = [10000,9200,11811,12000,7662,13887,14200,12222,12000,10009,11288,12099];

                        // Create the chart within it's "holding" node
                        var chart = new Chart("barchartNode");

                        // Set the theme
                        chart.setTheme(theme);

                        // Add the only/default plot

                        chart.addAxis("y", { vertical: true, fixLower: "major", fixUpper: "major" });

                        // Add the series of data
                        chart.addSeries("Monthly Sales",chartData);

                        // Highlight!
                        new Highlight(chart,"default");

                        // Render the chart!

你可以挂钩onAfterTransitionIn或onBeforeTransitionIndojox/mobile/SwapView

引自 Dojo 参考

从您的应用程序连接到的存根函数。在到达转换发生之前/之后调用。
