Question

我试图找出生产机器上IE9中可能导致问题的原因。我们有一个<select>组合框，其中包含一个内联更改处理程序（我意识到这是一个不好的做法，但我现在无法做任何事情）但是没有被调用。

HTML如下所示（从开发工具中复制）

<select name="propertyName" id="propertyName" onchange="Workflows.CoreSetPropertyActivity._field_OnChange();">
  <option value="Property_103156" title="Boolean Prop" selected="selected">Boolean Prop</option>
  <option value="Property_103072" title="String Prop A">String Prop A</option>
</select>

在与客户的webex上，我在Workflows.CoreSetPropertyActivity._field_OnChange()中放置一个断点并且没有被调用（在IE9中）。如果我从控制台手动调用它，一切正常。

我们使用IE8进入完全相同的机器，并且Workflows.CoreSetPropertyActivity._field_OnChange()被调用，一切正常。

我认为唯一可能相关的其他信息是下拉列表是动态创建的。

有人碰到类似的东西吗？有什么尝试的建议吗？也许在IE中可以打破这个法术的一些设置？

创建HTML

使用以下代码将选择添加到页面中。要插入的HTML看起来像

<div class="wrapper">

    <ul id="setStateConditions">
        <li class="setStateLabel">Property Name</li>
        <li class="setStateContent">

<option value='Property_103156' title='Boolean Prop'  selected='selected' >Boolean Prop</option>
<option value='Property_103072' title='String Prop A' >String Prop A</option>

Answer 1

事实证明，问题是客户正在运行IE9 with the release to manufacturing version (RTM)，这是GA发布之前的Internet Explorer预发布版。

客户在另一台机器上安装了IE9，问题就消失了。我非常有信心，当他们在那台机器上重新安装IE时，它将被修复。

感谢大家投球。

IE9中没有为select元素调用内联处理程序
