自定义字段定义

在SharePoint 2013上,我在列表中的字段遇到麻烦,我通过schema.xml文件定义该字段。我们从2007年升级到可以正常工作,但升级到2013年后,从新版本创建列表时不再有效。

历史:

该字段是一个自定义字段,用于输出包含链接的图像,该链接使用javascript动态显示。这是使用display pattern和cdata定义的。

我们在schema.xml文件中定义了以下字段:

<Field ID="{A54A4AE0-CA79-47b0-819E-32DC1B3F5AFB}" ReadOnly="TRUE" Type="Computed" Name="Book" Sortable="FALSE" Filterable="FALSE" DisplayName="Book" ClassInfo="Icon" AuthoringInfo="(link to book item)" SourceID="http://schemas.microsoft.com/sharepoint/v3" StaticName="Book" FromBaseType="TRUE">
        <DisplayPattern>
          <HTML><![CDATA[<a href="javascript:" OnClick="javascript:this.href=L_Menu_BaseUrl + '/Lists/Bookings/NewForm.aspx?Session_x0020_Name=]]></HTML>
          <Column Name="ID" />
          <HTML><![CDATA[';GoToLink(this);return false;" target="_self">]]></HTML>
          <HTML><![CDATA[<img border="0" alt="]]></HTML>
          <HTML>Book</HTML>
          <HTML><![CDATA[" src="/_layouts/images/Book.GIF">]]></HTML>
          <HTML><![CDATA[</a>]]></HTML>
        </DisplayPattern>
      </Field>

当使用此架构从new启动列表时,它不再有效,它会创建book字段,但它只是空白。

我尝试过:

经过研究,我了解到自定义字段现在应该用xsl文件定义:

C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\TEMPLATE\LAYOUTS\XSL

所以我创建了一个名为fldtypes_Book.xsl

的xls文件

其中的内容如下所示(目前我只想输出简单的文字以使其正常工作):

<xsl:stylesheet xmlns:x="http://www.w3.org/2001/XMLSchema"
                xmlns:d="http://schemas.microsoft.com/sharepoint/dsp"
                version="1.0"
                exclude-result-prefixes="xsl msxsl ddwrt"
                xmlns:ddwrt="http://schemas.microsoft.com/WebParts/v2/DataView/runtime"
                xmlns:asp="http://schemas.microsoft.com/ASPNET/20"
                xmlns:__designer="http://schemas.microsoft.com/WebParts/v2/DataView/designer"
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:msxsl="urn:schemas-microsoft-com:xslt"
                xmlns:SharePoint="Microsoft.SharePoint.WebControls"
                xmlns:ddwrt2="urn:frontpage:internal">  
  <xsl:template match="FieldRef[@ID='A54A4AE0-CA79-47b0-819E-32DC1B3F5AFB']" mode="Computed_body"  priority="1">
    <xsl:param name="thisNode" select="."/>
    <span>Hello.</span>      
  </xsl:template>
</xsl:stylesheet>

再次这不起作用,它只输出字段但字段为空。

我知道该字段与xsl文件挂钩,因为如果我输入一些错误的标签或随机混乱到文件列表中断。

经过研究,我发现了这个:

并尝试将js文件上传到母版页并在列表Web部件设置上链接到它,但没有任何反应,我的js文件的内容:

(function () {

//   Initialize the variables for overrides objects
    var overrideCtx = {};
    overrideCtx.Templates = {};

//  alert("Override call worked");

//  Use BaseViewID and ListTemplateType to narrow focus/scope on 
//  which web parts on the page are affected
//  overrideCtx.BaseViewID = 1;
//  overrideCtx.ListTemplateType = 100;

    /*
     * Using the Fields override leaves the rest of the rendering intact, but 
     * allows control over one or more specific fields in the existing view
     */
    overrideCtx.Templates.Fields = {
        'Book': { 'View' : 'Hello' }
    };

    /*
     * Register the template overrides.
     */
    SPClientTemplates.TemplateManager.RegisterTemplateOverrides(overrideCtx);
})();

非常感谢任何帮助。

尝试在DisplayPattern定义之前放置已使用字段的FieldRef(同样,确保也定义了这些字段),如下所示:

public class AuditHandler {

    public void auditRequest(String appName, ServletRequest request) {
        System.out.println(appName + ": Received request from " + request.getRemoteAddr() );
    }
}

public class AuditFilter implements Filter {

    private final AuditHandler auditHandler;
    private String appName;

    public AuditFilter(AuditHandler auditHandler) {
        this.auditHandler = auditHandler;
    }

    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {

        auditHandler.auditRequest(appName, request);
        chain.doFilter(request, response);
    }

    public void init(FilterConfig filterConfig) throws ServletException {
        appName = filterConfig.getInitParameter("appName");
    }

    public void destroy() {}
}

不要忘记重新创建列表,这将有助于sharepoint“查看”您的更新。祝你好运!
