我想通过使用jquery做下面的步骤.有谁知道很好的解决方案？
获取"ul"元素的DOM对象.
<ul id="rows">
<li class="row1">
<a class="row1-1" href="/kensaku2/Page1" title="page1">
2011/11/16</a>
</li>
<li class="row2">
<a class="row1-2" href="/kensaku2/Page2" title="page2">
2011/11/15</a>
</li>
<li class="row3">
<a class="row1-3" href="/kensaku2/Page3" title="page3">
2011/12/21</a>
</li>
<li class="row4">
<a class="row1-4" href="/kensaku2/Page4" title="page4">
2011/12/05</a>
</li>
</ul>
找到"a"元素的内容等于'2011/12/21'.(这是"row3"li元素.)
将"li"元素移动到头部.(另见波纹管代码.)
<ul id="rows">
<li class="row3">
<a class="row1-3" href="/kensaku2/Page3" title="page3">
2011/12/21</a>
</li>
<li class="row1">
<a class="row1-1" href="/kensaku2/Page1" title="page1">
2011/11/16</a>
</li>
<li class="row2">
<a class="row1-2" href="/kensaku2/Page2" title="page2">
2011/11/15</a>
</li>
<li class="row4">
<a class="row1-4" href="/kensaku2/Page4" title="page4">
2011/12/05</a>
</li>
</ul>
我已经知道如何获得像这样的"ul"元素的DOM对象.
$("#rows").get(0)
但我不知道第2步和第3步.所以,我想问专家.
我是WCF的初学者,我正在Essential WCF学习.
我在使用ServiceContract NameSpace和Name时遇到了问题.当我运行代码时,我发现了一个波纹管InvalidOperationException.但我无法理解清楚.
绑定实例已与侦听URI"http:// localhost:8080/NamespaceChange01"相关联.如果两个端点想要共享相同的ListenUri,则它们还必须共享相同的绑定对象实例.两个冲突的端点要么在AddServiceEndpoint()调用中,在配置文件中指定,要么在AddServiceEndpoint()和config的组合中指定.
有谁知道如何使用InvalidOperationException？

}

public class BurgerMaster : IBurgerMaster
{
public double GetStockPrice(string ticker)
{
return 100.99;
}
}

所以,我想问专家如何解决问题.

我想从代码中更改DataTemplate中TextBlock的前景颜色(下面的TitleText和DateText).
<ListBox x:Name="listBox1" ItemsSource="{Binding}" ScrollViewer.ManipulationMode="Control" SelectionChanged="listBox1_SelectionChanged">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel x:Name="stackPanel1" HorizontalAlignment="Stretch" Orientation="Horizontal">
<TextBlock FontSize="35" x:Name="TitleText" Text="{Binding Title}" Width="386" Foreground="Black" />
<TextBlock FontSize="25" x:Name="DateText" Text="{Binding Date}" Width="78" Foreground="Black" />
<TextBlock x:Name="Id" Text="{Binding Id}" Visibility="Collapsed" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
我想在代码背后这样做.但它似乎无法访问DataTemplate中的x:Name属性.
this.TitleText.Foreground = new SolidColorBrush(Color.FromArgb(0, 0, 0, 0);
有谁知道这个很好的解决方案？
