SharePoint 优化显示WebParts

　　在开发sharepoint中,经常遇到需要自定义显示列表中的一部分作为导航的内容, 如公告栏,新闻链接,最新动态等....
　　
　　我们通常需要显示一个列表的标题,并且限制字符长度, 外加一些条件,如按创建的时间倒序这样来显示最新的动态, 显示的时间也需要转换格式等...
　　
　　那我们来看看原始的列表如下图：

　　
　　修改后的效果：

接下来我们用SPD打开这个站点,在sitepages里面新建一个页面, 命名为allexception, 这是个空白的页面, 然后点击插入显示表单
　　我们需要显示显示多少行,找到<asp:Parameter Name="MaximumRows" DefaultValue="5"/> 这样我们就让行数限制在5行,另外我们在<xsl:variable name="RowLimit" select="5" />也修改成5
　　我们还需要显示根据标题的长度比喻小于18个字符的全部显示,大于18个字符的显示其中的一部分外加省略号..
另外根据条件,如Status的Approved显示绿色,Denied显示为红色.
如下是代码：

<table border="0" cellspacing="0" width="100%">
<tr>
<td width="75%" class="ms-vb">
<a target="_blank" title="{@Title}">
<xsl:attribute name="href">http://liangji27/sites/charlie/Lists/Excemption%20Request/DispForm.aspx?ID=<xsl:value-of select="@ID"></xsl:value-of></xsl:attribute>
<xsl:if test="string-length(@Title)<=18">
<xsl:if test="@Status='Approved'">
<font color="#7FFF00"><xsl:value-of select="@Title" /></font>
</xsl:if>
<xsl:if test="not(@Status='Approved')">
<font color="#FF0000"><xsl:value-of select="@Title" /></font>
</xsl:if>
</xsl:if>
<xsl:if test="string-length(@Title)>18">
<xsl:if test="@Status='Approved'">
<font color="#7FFF00"><xsl:value-of select="substring(string(@Title),1,18)" />...</font>
</xsl:if>
<xsl:if test="not(@Status='Approved')">
<font color="#FF0000"><xsl:value-of select="substring(string(@Title),1,18)" />...</font>
</xsl:if>
</xsl:if>
</a>
</td>
<td width="25%" class="ms-vb">
<xsl:value-of select="substring(string(@Created_x0020_Date),4,10)"></xsl:value-of>
</td>
</tr>
</table>
　　
　　此处是将创建时间格式截取年月日：

<xsl:value-of select="substring(string(@Created_x0020_Date),4,10)"></xsl:value-of>
　　以上是全部代码：
