Hi David. > So, where is the <select/>? Inside each element's lens? Or just a common > one for the whole page? When does the user choose something in it? > Before you load the data? After you load the data?...
currently the select is defined within the lens and i load the data as per the
examples on the webpage. the user would select something on the <select/> after
the data loads - from within the lens. basically i would like to replace the
img tag's src attribute a concatenation of '.graphUtil' and the value of the
<select/>.
<link href="/cgi-bin/exhibit.cgi?mode=port_list&device=xxx.yyy.zzz"
type="application/json" rel="exhibit/data" />
...
<div ex:role="exhibit-lens" class="item">
<table>
<tr>
<td>
<p><h2>Device <span ex:content=".node"></span> | Port <span
ex:content=".label"></span></h2></p>
<b>Alias</b>: <span ex:content=".alias"></span> <b>Peer</b>: <span
ex:content=".peer"></span></br>
<b>Settings</b>:
<span ex:content=".speed"></span>mbps /
<span ex:content=".duplex"></span> /
<span ex:content=".port_fast"></span>
<p><b>Display</b>:
<script>
// on change; update the uri of the graphs
function changeGraphPeriods( period ) {
var arg = "&period=" + period;
// get basically does a getElementById
my orig = get( 'graphUtil').src;
// of course some filtering of the previous arg value will be
required
get( 'graphUtil' ).src = orig + arg;
// do the same for the Error graph
// this doesn't work because the html that is rendered by
exhibit does not
// contain the id attribute - even though it does exist in the
lens definition
}
</script>
<select id="period" onChange="changeGraphPeriods(this.value);">
<option value="2d">2 days</option>
<option value="2w">2 week</option>
<option value="2m">2 months</option>
<option value="1y">1 year</option>
</select>
</p>
<p id="graphs">
<img id="graphUtil" ex:src-content=".graphUtil"/><br/>
<img id="graphUtil" ex:src-content=".graphError"/><br/>
</p>
</td>
</tr>
</table>
</div>
if there is another way i could do this, i'll be more than happy to try it.
thanks!
Yee.
