how to retreive a number of line as record to display ? or to calculate to know if a number of line is odd or even

[Naples1966]

I don't find the solution to retreive a number of line as record to calculate to know if this  is odd or even.

if even,  set the green in color of record  , if no, gray in color of record.

Because, I would like to appear the alternating color of line in a table.

there is my script, see below. May you help it   please ?. Thank you in advance for your return

<g2:evaluate var="jvar_inc">
var inc = new GlideRecord('incident');
var color;

inc.addActiveQuery();
inc.addQuery('priority',1);

//** here : how to retreive a number of line as record ? **//

//** ROW as a number of line **//

var row = inc.getRowNumber();
row;

if(row % 2 == 0){
Color = "even";
}else{
Color= "odd";
}

inc.setCategory('homepage');
inc.query();
</g2:evaluate>

<style>
.odd{background-color: white;}
.even{background-color: gray;}
</style>

<table class="fixed_header" >
<tbody >
<j2:while test="$[inc.next()]">
<j2:set var="jvar_inc_link" value="incident.do?sys_id=$[inc.sys_id]"/>
<j2:set var="jvar_inc_list_link" value="incident_list.do?sysparm_query=active=true"/>

<tr class="${color}">
<td ....</td>
</tr>
</j2:while>

</tbody>
</table>

Everything I've read about .getRowNumber() has been a performance drag.  You dont need to use that but you could just as easily make your own variable;

<?xml version="1.0" encoding="utf-8" ?>
<j:jelly trim="false" xmlns:j="jelly:core" xmlns:g="glide" xmlns:j2="null" xmlns:g2="null">
test<br/>
	<g:evaluate jelly="true" object="true">
	var i=0;
	var results = [];
		var inc = new GlideRecord('incident');
	//inc.addActiveQuery();
	//inc.addQuery('priority',1);
	inc.setLimit(10);
	inc.query();
	while(inc.next()){
	  results.push({
		link: inc.getLink(),
		listLink: inc.getTableName() + '_list.do?sysparm_query=' + inc.getEncodedQuery(),
		className: parseInt(results.length,10) % 2 == 0 ? 'even' : 'odd'
	  });
	}
</g:evaluate>
<!--results: ${results.length}
    results.length: ${results.length}<br/>
	results: ${results}<br/>
	results[0]: ${results[0]}<br/>-->
	<table><tbody>
	<j:while test="${results.length!=i}">
		<tr class="${results[i].className}">
			<td>${results[i].link}</td>
			<td>${results[i].listLink}</td>
		</tr>
		<g:evaluate var="not_important" expression="i++"/>
	</j:while>
		</tbody></table>
</j:jelly>

First of all, thank you for your answer.

Since this is the first time to build the script in the service, I have trouble understanding your script and I have not found anything missing to fix ....

Because, I copied your processing into the PAGE UI, and then I renamed a classname ("color" instead of "classname") and I removed some spaces. for instance  : "color:parseInt(results.length,10)%2==0 " instead of "

className: parseInt(results.length,10) % 2 == 0 ? 'even' : 'odd'

 "

It did not work! ... Sorry ...

See below, I put your processing copied from the UI page . Is it correct ?

<?xml version="1.0" encoding="utf-8" ?>
<j:jelly trim="false" xmlns:j="jelly:core" xmlns:g="glide" xmlns:j2="null" xmlns:g2="null">
test<br/>
<g:evaluate jelly="true" object="true">
var i=0;
var results = [];
var inc = new GlideRecord('incident');
//inc.setCategory('homepage');
inc.setLimit(10);
inc.query();

while(inc.next()){
results.push({
link:inc.getLink(),
listLink:inc.getTableName()+'_list.do?sysparm_query='+inc.getEncodedQuery(),
color:parseInt(results.length,10)%2==0 ? 'even' : 'odd'
});
}
</g:evaluate>

results: ${results.length}
results.length: ${results.length}<br/>
results: ${results}<br/>
results[0]: ${results[0]}<br/>

<table><tbody>
<j:while test="$[inc.next()]">
<tr class="${results[i].color}">
<td>${results[i].link}</td>
<td>${results[i].listLink}</td>
</tr>
<g:evaluate var="not_important" expression="i++"/>
</j:while>
</tbody></table>
</j:jelly>

When you say it doesn’t work what does it do? Did you try it with out modification?
