Empty List collector ?

sandaru · ‎07-14-2016

Hi,

I'm in a need of creating an empty list collector. Since we cannot initiate an empty list controller, what i'm going to do is run an onLoad script to remove all the elements from the List collector and add it manually via a script.

Can i do this ? and how to do that ?

All the way i searched i only found some thing called "move" which moves elements from left to right and vise versa.

Thank you.

Here is how you can do it. You will have use filter string sys_id=''; This will load you with empty list collector

function onLoad() {

//Apply a default filter to the list collector variable

var collectorName = 'configuration_items';

var filterString = 'sys_id='+'';

//Hide the list collector until we've set the filter

g_form.setDisplay(collectorName, false);

setCollectorFilter();

function setCollectorFilter(){

//Test if the g_filter property is defined on our list collector.

//If it hasn't rendered yet, wait 100ms and try again.

if(typeof(window[collectorName + 'g_filter']) == 'undefined'){

setTimeout(setCollectorFilter, 100);

return;

}

//Find the filter elements

var fil = gel('ep');

//Hide the filter elements by un-commenting the following lines

/*fil.rows[0].style.display = 'none';

fil.rows[1].style.display = 'none';

fil.nextSibling.rows[0].style.display = 'none'; //Filter description text*/

//Reset the filter query

window[collectorName + 'g_filter'].reset();

window[collectorName + 'g_filter'].setQuery(filterString);

window[collectorName + 'acRequest'](null);

//Redisplay the list collector variable

g_form.setDisplay(collectorName, true);

}

which release are you on? Can you attach a snapshot of your script

the second one should also work and it is much easier to implement.Try this

setCollectorFilter();

function setCollectorFilter(){

var varName = 'YOUR_VARIABLE_NAME_HERE';

//Test if the g_filter property is defined on our list collector.

//If it hasn't rendered yet, wait 100ms and try again.

if(typeof(window[varName + 'g_filter']) == 'undefined'){

setTimeout(setCollectorFilter, 100);

return;

}

var leftBucket = gel(varName + '_select_0');

var rightBucket = gel(varName + '_select_1');

rightBucket.options.length=0;

leftBucket.options.length=0;

}

Here is the tested one. this should work for u too

function onLoad() {

   setTimeout(setCollectorFilter, 3000);

   function setCollectorFilter(){

   var varName = 'list collector name';

   var leftBucket = gel(varName + '_select_0');

   var rightBucket = gel(varName + '_select_1');

   rightBucket.options.length=0;

   leftBucket.options.length=0;

   }

}

Hi Abhinay, I was wondering if you've happened to have worked with 2 list collector(LC) variables on a single cat item ? I am actually stuck where in the second LC variable is just adding the sysID of the first LC variable in its filter & this is resulting in 2 blank slush buckets.

But if there is only 1 value in the first LC var, the second LC var seems to work just fine. Issue occurs only when I add more values in the first LC var...Your thoughts on this mate ?
