Question

我尝试使用setPanel（）显示文本路线。 Google的示例适用于IE9，但我的测试页面在IE9上存在问题，尽管我复制相同的代码。方向面板中的方向箭头不随文本滚动，它们保持固定。 Chrome没问题。为什么？谢谢。代码如下：

我遇到了同样的问题。我终于能够通过覆盖箭头图标的css样式和它的容器来解决它。加载google api脚本后，在页面中添加以下样式定义：

    /* Override Google Maps Icon style */
    .adp-substep .adp-stepicon .adp-maneuver {
        position: static;
    }

    /* Override Google Maps Icon Container style */
    .adp-substep .adp-stepicon{
        position: static;
    }

这会覆盖google api自动在这些类上使用的位置：绝对。仍然不确定为什么绝对有时会像固定一样，但这种覆盖对我有用。
