Question

当我更改指标值时，我想获得指标的值。从那我想设置其他指标值。 dojo中是否有任何指标值变化的事件。我使用下面的代码，但它不起作用。警报无效。

    makeGauge2 = function() {
    GaugeInPounds = new dojox.gauges.GlossySemiCircularGauge({
        background : [ 255, 255, 255, 0 ],
        title : 'Value',
        id : "glossyGauge2",
        width : 300,
        height : 300,
        max:200,
        majorTicksInterval:20,
        minorTicksInterval:10
    }, dojo.byId("GaugeInPounds"));
    GaugeInPounds.startup();


};
dojo.ready(makeGauge);
dojo.ready(makeGauge2);
//var gauge1 = dijit.byId("GaugeInPounds");
dijit.byId("GaugeInPounds").on("startEditing", function(event){
    alert(event.indicator.value);
    console.log(event.indicator.value);});
