Hide elements and 'View more' using jQuery
JavaScript is not my strong point, but then I'm not sure I'm hitting this from the right direction.
Firstly, I have some XSLT which produces HTML tables with event information in them. I assign a numerical ID to each table which matches the XSL position().
What I want to achieve is to show only the first 10 tables, until the use clicks a 'View More' link then the next 10 tables are shown until the end of the elements.
I'm having a problem from the outset in that the code that I have written is not hiding the tables over 10 and now the page is crashing in what I assume is an endless loop:
Here is the XSLT:
<xsl:for-each select="umbraco.library:GetMedia(1116, 'true')/node">
<xsl:variable name="fileName" select="data [@alias = 'file']" />
<xsl:variable name="tableID" select="position()" />
<table id="{$tableID}">
<tr>
<td class="eventDate">
<xsl:value-of select="dat开发者_开发知识库a [@alias = 'eventDate']"/></td>
<td><a href="/downloader?file={$fileName}" target="_blank()" class="eventTitle"><xsl:value-of select="data [@alias = 'title']"/></a></td>
</tr>
<tr>
<td> </td>
<td class="newsSubTitle"><xsl:value-of select="data [@alias = 'subTitle']"/></td>
</tr>
<tr>
<td colspan="2">
<img src="images/borders/news_separator.gif" />
</td>
</tr>
</table>
</xsl:for-each>
Here is the JavaScript:
<script type="text/javascript" language="javascript">
$(document).ready(function () {
var rc = $('#eventReportsList table').length;
if(rc > 10) {
var i=0;
for (i=11;i=rc;i++) {
var currElement = '#' + i;
$(currElement).hide();
}
};
alert('Count ' + rc);
});
</script>
Some assistance or pointers in the right direction would be great!
Thanks.
To hide tables from 11-th on:
$('table:gt(9)').hide();
:gt(x)
selects siblings with indices (0-based) greater than x
;
To show hidden tables again:
$('table:hidden').show();
Changed XSL:
<xsl:variable name="tablesPerSet" select="10" />
<xsl:for-each select="umbraco.library:GetMedia(1116, 'true')/node">
<xsl:variable name="posZ" select="position() - 1" />
<xsl:variable name="tableSetId" select="
($posZ - ($posZ mod $tablesPerSet)) div $tablesPerSet
" />
<table class="hideable tableSet_{$tableSetId}">
<!-- ... -->
</table>
</xsl:for-each>
Results in:
<table class="hideable tableSet_0"></table><!-- #1 -->
<!-- ... -->
<table class="hideable tableSet_0><!-- #10 -->
<table class="hideable tableSet_1"></table><!-- #11 -->
<!-- and so on -->
So you can do with jQuery
// first hide all, then show only those that match i
$("table.hideable").hide().is(".tableSet_" + i).show();
I trust you'll manage incrementing/decrementing i
while keeping it in a valid range yourself. ;)
I've not looked at it too much, but your jQuery seems a bit OTT. Something like:
$('table').filter(function(index) {
return index > 10;
}).hide();
will hide the 11th table onwards on your page. If you're using tables elsewhere, just give them all a class like hideable and do
$('.hideable').filter(function(index) {
return index > 10;
}).hide();
