Print Counter using XML code

Lokesh5 · ‎11-03-2024

Hi,

I was trying to print counter of numbers in a table using JSP code in servicenow. However, the counter is not working as excepted, its throwing null values. Please find my script below and correct me.

Thanks in advance!
----------------------------------------------------------

<tr>

<th style="background-color: #1f4e79; color: white; width: 5%;">OBS Number</th>

<th style="background-color: #1f4e79; color: white; width: 40%;">Observations Title</th>

<th style="background-color: #1f4e79; color: white; width: 15%;">Rating</th>

<th style="background-color: #1f4e79; color: white; width: 20%;">Responsible Party</th>

<th style="background-color: #1f4e79; color: white; width: 20%;">Action Plan Target Date</th>

</tr>

<j:if test="${jvar_issuesenddate.getRowCount() > 0}">

var jsCounter = 1;

</script>

<j:while test="${jvar_issuesenddate.next()}">

<tr>

document.writeln(jsCounter++);

</script>

</td>

<td>${jvar_issuesenddate.getValue('short_description')}</td>

<td>${jvar_issuesenddate.getDisplayValue('assigned_to')}</td>

<td>${jvar_issuesenddate.getValue('u_target_date')}</td>

</tr>

</j:while>

</j:if>

</table>

@Lokesh5 It looks like the issue is that the counter jsCounter is being incremented using JavaScript within the JSP while loop. However, JavaScript runs client-side, while the JSP <j:while> loop is processed server-side. This mismatch can lead to unexpected behavior, as jsCounter will not increment as expected across server-side iterations.

To handle this correctly, you should maintain the counter using JSP Server side code.

Hope this will help you.

Hi @Community Alums ,

Thanks for the quick response. I have followed the way which you suggested and its working. However, the counter is returning in decimal values like 1.0, 2.0..... I have tried all the conversion menthods but no luck. Could you please check my below code and suggest the way to eliminate decimals.

<g:evaluate object="true" var="jvar_issuesenddate">

var issueId = [];

var counter = 1;

var engagementId = current.getValue('sys_id');

var controlTest = new GlideRecord('sn_audit_control_test');

controlTest.addQuery('top_task', engagementId);

controlTest.addQuery('issue', '!=', '');

controlTest.query();

while (controlTest.next()) {

issueId.push(controlTest.issue + '');

}

var issues = new GlideRecord('sn_grc_issue');

issues.addQuery('sys_id', 'IN', issueId.join(',')).addOrCondition('sn_audit_engagement', engagementId);

issues.orderBy('number');

issues.query();

issues;

</g:evaluate>

<body>

<tr>

<th style="background-color: #1f4e79; color: white; width: 5%;">OBS Number</th>

<th style="background-color: #1f4e79; color: white; width: 40%;">Observations Title</th>

<th style="background-color: #1f4e79; color: white; width: 15%;">Rating</th>

<th style="background-color: #1f4e79; color: white; width: 20%;">Responsible Party</th>

<th style="background-color: #1f4e79; color: white; width: 20%;">Action Plan Target Date</th>

</tr>

<j:if test="${jvar_issuesenddate.getRowCount() > 0}">

<j:while test="${jvar_issuesenddate.next()}">

<tr>

${Math.floor(counter)}

</td>

<td>${jvar_issuesenddate.getValue('short_description')}</td>

<td>${jvar_issuesenddate.getValue('rating')}</td>

<td>${jvar_issuesenddate.getDisplayValue('assigned_to')}</td>

<td>${jvar_issuesenddate.getValue('u_target_date')}</td>

</tr>

<g:evaluate>

counter++

</g:evaluate>

</j:while>

</j:if>

</table>

@Lokesh5 use parseInt to explicitly convert it so it will make sure output is shown as an integer.
