我需要有人引导/指导我在哪里编码错误，因为我无法弄清楚我的代码哪里出错了。此代码在我的 IE 和 FF 中运行良好，但在 Chrome 或 Safari 中运行良好。右边，当我单击下拉列表选择时，它将显示所选位置的确切地图。但是在我的 Chrome 和 Safari 中，它只显示了初始地图，而不是显示从列表中选择的位置。

添加onclick到 an<option>似乎不是一个好主意。我会改为使用onchangeon<select>并使用value属性来存储 lat/lng：

<select onchange="movemap(this)">
    <option value="1.28563,103.80918">Blk 18a Jln Membina</option>
    ...

function movemap(sel)
{
    var opt = sel.options[sel.selectedIndex],
    vals = opt.value.split(',');

    initialize(vals[0], vals[1]);
}
