    <p>I have the below chunk of code. I've debugged through and located the snippet that is causing a long delay in IE6.</p> <p>Basically the code loops through a document converting it to XML and sending to a PDF. On Ubuntu and Firefox 4 it takes 3 seconds. On IE it can take up to 40 seconds regularly.</p> <pre><code>/** * This function builds up the XML to be saved to the DM. */ function getXMLToSave(){ var text="&lt;workbook&gt;&lt;sheet&gt;&lt;name&gt;Adv4New&lt;/name&gt;"; //show_props(document.adv4.row10col1, "document.adv4.row10col1"); for(i=1;i&lt;157;i++){ text = text + "&lt;row number='" + i + "'&gt;"; for(j=1;j&lt;=7;j++){ text = text + "&lt;col "; //alert(eval('document.adv4.row'+i+'col'+j+'.readonly')); try{ text = text + "number='" + j + "' label='" + eval('document.adv4.row'+i+'col'+j+'.className')+ "'"; } catch (e) { text = text + "number='" + j + "' label=''"; } try { if(eval('document.adv4.row'+i+'col'+j).readOnly) text = text + " type='readonly'"; else text = text + " type=''"; } catch (e) { text = text + " type=''"; } try { text = text + " color='" + eval('document.adv4.row'+i+'col'+j+'.style.color') + "'"; } catch (e) { text = text + " color=''"; } text = text + "&gt;"; try { // don't wrap in a CDATA (like previously), but run cleanNode // this fixes html entities var content = eval('document.adv4.row'+i+'col'+j+'.value'); text = text + cleanNode(content); } catch (e) { text = text + "0"; } text = text + "&lt;/col&gt;"; } text = text + "&lt;/row&gt;"; } text = text + "&lt;/sheet&gt;&lt;/workbook&gt;"; return text; </code></pre> <p>}</p> <p>I believe its the eval function causing the delay in IE6. Is there a neat solution to fix this. Thanks very much</p>

    2. COWhat exactly is it that your eval is trying to accomplish? It looks like you could just as easily access the color property by doing this: document.adv4['row' + i + 'col' + j].style.color

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
