IE9 Javascript未定义错误

时间:2011-04-15 13:02:40

标签: javascript asp.net internet-explorer

我在IE9中遇到javascript错误,我没有在Chrome或FF中获取,我无法找到解决问题的好方法。代码 在兼容模式下工作。

在示例代码中,我有一个自定义用户控件,它由一些基本控件和一个AJAX modelpopupextender组成。 listview填充了一些产品,我附加了一个onclick事件onitemdatabound,它填充了一个标签,并将modelpopup关闭到listview项的每个htmlrow。

IE9找不到Button2,无法完成javascript功能。当前版本的Chrome和FF按预期执行。有什么我想念的吗?

更新

好的,我找到了解决方法。我添加了一个执行进程的js函数。

<script type="text/javascript">
    function selectProduct(prodName) {
        document.getElementById('<%= Label1.ClientID %>').innerText = prodName;
        document.getElementById('<%= Button2.ClientID %>').click();
    }
</script>

...

Dim row As HtmlTableRow = CType(e.Item.FindControl("selectedProduct"), HtmlTableRow)
Dim lblName As Label = e.Item.FindControl("lblName")
Dim product As String = ListView1.DataKeys(CType(e.Item, ListViewDataItem).DataItemIndex).Values(1).ToString()
Dim id As String = ListView1.DataKeys(CType(e.Item, ListViewDataItem).DataItemIndex).Values(0).ToString()
row.Attributes.Add("onclick", "selectProduct(" + lblName.ClientID + ".innerText);")

唯一的问题是,我要么必须每页只放置一个此用户控件,要么为每个控件注册客户端脚本服务器端的唯一函数名称。

至少我得到了它的工作。

您可能想尝试更改:

row.Attributes.Add("onclick", Label1.ClientID + ".innerText=""" + product + """;" + Button2.ClientID + ".click();")

为:

row.Attributes.Add("onclick", Label1.ClientID + ".innerText=""" + product + """;document.getElementById(""" + Button2.ClientID + """).click();")

我有自定义WebControl的类似问题。我将问题追溯到ASP.NET。

简而言之,ASP.NET不了解IE9浏览器ID,因此返回默认的兼容性标志,包括EcmaScriptVersion(请参阅System.Web.HttpContext.Current.Request.Browser),它会关闭基类中的脚本生成。

我真的希望他们在IE9发布后更新.net,但不会。

这些是(独立的)解决方案,我用它来规避这种烦恼:

  1. 启用带控件的页面上的兼容性视图(请参阅X-UA-Compatible),最好是作为元标记来强制重新加载页面;
  2. browserCaps部分添加到您的web.config(这将有效打开所有浏览器的Cookie和javascript):

    <configuration>
        <system.web>
            <browserCaps>
                <use var="HTTP_USER_AGENT" />
                browser=Unknown
                cookies=true
                javascript=true
                ecmascriptversion=1.0
            </browserCaps>
        </system.web>
    </configuration>
    
  3. 了解如何强制控件生成所需的脚本,无论是什么(这个脚本仍处于待处理状态)。
