Question

我需要放置显示股票行情的RSS查看器Web部件，以供JPMorgan Chase使用。

我找到的RSS提要是：http://www.quoterss.com/quote.php?symbol=JPM&format=0&uid=1280868448但他的提要还会检索不必要的链接，例如FaceBook作弊码，Iphone作弊码......我想隐藏那些不必要的作弊码链接。

下面提供了具有上述提要的RSS查看器Web部件的XSLT。

                </xsl:otherwise>
            </xsl:choose>
        </xsl:template>

</xsl:stylesheet>

从上面的XSLT我可以看出HTML是自动生成的，由

完成

        <xsl:template name="GetSafeHtml">
            <xsl:param name="Html"/>
            <xsl:choose>
                <xsl:when test="$rss_IsDesignMode = 'True'">
                     <xsl:value-of select="$Html"/>
                </xsl:when>
                <xsl:otherwise>
                     <xsl:value-of select="rssaggwrt:MakeSafe($Html)"/>
                </xsl:otherwise>
            </xsl:choose>
        </xsl:template>

如果我朝着正确的方向前进，如果自动生成HTML，我将无法使用XSL隐藏这些不必要的链接。所以我尝试使用JQuery做到这一点。

自动生成的HTML如下所示。

<table border=0 cellspacing=0 cellpadding=1 width=150><tr><td bgcolor="#000000"> <table border=0 cellspacing=0 cellpadding=0 width="100%" class="pq_all"> <tr bgcolor="#DDDDDD"><td width="100%" align=CENTER colspan=3 nowrap> </td></tr> <tr bgcolor="#EEEEEE"><td width="100%" nowrap>&nbsp;Last </td> <td width="40%" nowrap align=right>45.74</td></tr> <tr bgcolor="#DDDDDD"><td width="100%" nowrap>&nbsp;Change </td> <td width="40%" nowrap align=right><font color="#409940">+1.18</font>&nbsp;</td></tr> <tr bgcolor="#EEEEEE"><td width="100%" nowrap>&nbsp;% Change </td> <td width="40%" nowrap align=right><font color="#409940">2.65%</font>&nbsp;</td></tr> <tr bgcolor="#DDDDDD"><td width="100%" nowrap>&nbsp;Volume </td> <td width="40%" nowrap align=right>77445704&nbsp;</td></tr> <tr bgcolor="#EEEEEE"><td width="100%" nowrap>&nbsp;Last </td> <td width="40%" nowrap align=right>4:02pm&nbsp;</td></tr> </table> </td></tr></table> _<div><a href="http://cheatcodes.com/iphone/">iPhone Cheat Codes</a></div>_

我想要隐藏包含对http:.//cheatcodes.com/iphone/的引用的链接，该链接在ITALIC中呈现为“iPhone作弊代码”。通过使用JQuery我试过

$('a[href*=http://cheatcodes.com]').hide()

......但这不起作用。我还试图深入研究它，当我尝试使用

获取href标签的值时

alert($('a[href*=http://cheatcodes.com]')).attr(href)

JQuery显示结果未定义。此外，作弊码的链接也会每天更新...我发现只有这部分网址保持不变的是：http：.// cheatcodes.com / ...根据我对HTML的理解自动生成JQuery无法隐藏该Anchor标记。

我有点被困在这里。如果有人告诉我行为和解决方案的确切原因，我真的很感激。此外，如果有人知道其他RSS提要，我可以获得摩根大通的股票报价将有助于克服这个问题。

谢谢， Dhaval

Answer 1

你试过alert($('a[href*="http://cheatcodes.com"]')).attr(href)吗？

需要隐藏<a> Tag that is generated automatically from other source</a>
