Question

I've found a resource suggesting there is a method do this，但引用的链接引发了Google代码错误。有没有人有任何在气球中使用javascript的例子？

我有几个例子：

<Placemark>
    <name>Object</name>
    <description><![CDATA[<br><br><br>
        <input value="Test" onchange="this.value=this.value.toUpperCase()">
    ]]></description>
<gx:balloonVisibility>1</gx:balloonVisibility>
    <Polygon>
        <extrude>1</extrude>
        <tessellate>1</tessellate>
        <outerBoundaryIs>
            <LinearRing>
                <coordinates>
                    -1.278059,53.020596,0 -1.278079,53.02062700000001,0 -1.278115,53.02065200000001,0 -1.278164,53.020667,0 -1.278219,53.02067,0 -1.278272,53.020662,0 -1.278316,53.020642,0 -1.278345,53.02061400000001,0 -1.278356,53.020582,0 -1.278346,53.020549,0 -1.278318,53.020521,0 -1.278274,53.020501,0 -1.278222,53.020491,0 -1.278167,53.020494,0 -1.278118,53.020508,0 -1.27808,53.020533,0 -1.27806,53.020563,0 -1.278059,53.020596,0 
                </coordinates>
            </LinearRing>
        </outerBoundaryIs>
    </Polygon>
</Placemark>

然而，我所能做的所有例子都不是很复杂。我无法弄清楚如何探索＆＃39;它要么......因为没有开发人员工具......

最终它是沼泽标准HTML。但是有一些限制。

alert（）不起作用 - 必须将所有消息写入元素。
VBS和其他脚本语言不起作用。（因为它不是IE控件）
范围非常有限 - 它看不到邻近地标/与之相互作用。
无法获取窗口对象
似乎无法创建objectURLs
