I am using jTemplates (jquery-jtemplates.js) to render a large xml
response by running xmlToJSON then processTemplate. Although the code
works fine, and performance in FF2.0 is acceptable (2672ms) on my test
system, I am getting a result of 9827ms when running in IE7. Is there
a known performance issue with jtemplates ? Are other templte modules
better ?
(p.s. the real world code uses jQuery Form plugin and web services,
but the sample below reproduces the issue)
Code, and template follow.
Template:
<table>
<thead><tr><th>Job#</th><th>Name</th><th>Client</th></tr></thead>
<tbody class="resultbody">
{#foreach $T.Job as row}
<tr>
<td>{$T.row.jobnum[0].Text}</td>
<td>{$T.row.jobname[0].Text}</td>
<td>{$T.row.clientid[0].Text}</td>
</tr>
{#/for}
</tbody>
</table>
Code:
