Hiding options in a list collector

[Red]

How can you hide certain options in a list collector depending on the "read" setting for a variable?

Could you provide the OnChange script

Hi,

Here's the code I used. Hope it's clear for you:

function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}

//Type appropriate comment here, and begin script below

var collectorName = 'collector_target_name_here';
var ListCollectors = g_form.getValue('collector_that_will_change');
var filterString = 'question.sys_name=Field target label';
var addQuery = '';

var arrayList = ListCollectors.split(",");
var arrayLength = arrayList.length;
var qArray = [
['sys_id of list option 1', '^value=General option 1^ORvalue=General option 2^ORvalueLIKEGeneral option 3'],
['sys_id of list option 2', '^valueLIKEModified option 1^ORvalue=Modified option 2^ORvalue=Modified option 3'],
['sys_id of list option 3', '^valueLIKENew option 1'],
['sys_id of list option 4', '^valueLIKEOld option 1'],
['sys_id of list option 5', '^valueLIKESkillsets 1'],
['sys_id of list option 6', '^valueLIKEPersonal option 1']
];


if (ListCollectors == 'sys_id of list option 7') {
// 'Contact unsuccessful':
addQuery = '^value=Response option 1^ORvalue=Response option 2';
}
else {

//use this if only 1 option is selected
if (arrayLength == 1) {
if (arrayList == 'sys_id of list option 1'){
addQuery = qArray[0][1];
}

else if (arrayList == 'sys_id of list option 2') {
addQuery = qArray[1][1];
}

else if (arrayList == 'sys_id of list option 3') {
addQuery = qArray[2][1];
}

else if (arrayList == 'sys_id of list option 4') {
addQuery = qArray[3][1];
}

else if (arrayList == 'sys_id of list option 5') {
addQuery = qArray[4][1];
}

else if (arrayList == 'sys_id of list option 6') {
addQuery = qArray[5][1];
}

}

else {

// use this if more than 1 option is selected
for (i = 0; i < arrayList.length; i++) {
// get the size of the inner array
var innerArrayLength = arrayList[i].length;

if (arrayList[i] == 'sys_id of list option 1'){
useQuery = qArray[0][1];
}

else if (arrayList[i] == 'sys_id of list option 2') {
useQuery = qArray[1][1];
}

else if (arrayList[i] == 'sys_id of list option 3') {
useQuery = qArray[2][1];
}

else if (arrayList[i] == 'sys_id of list option 4') {
useQuery = qArray[3][1];
}

else if (arrayList[i] == 'sys_id of list option 5') {
useQuery = qArray[4][1];
}

else if (arrayList[i] == 'sys_id of list option 6') {
useQuery = qArray[5][1];
}

if ( i == 0 ) {
addQuery = useQuery;
}
else {
//replace value format of the first value in the string and concatenate with the default query value
addQuery = addQuery.concat(useQuery.replace(/^.{6}/g, '^ORvalue'));
}


}

}

}

filterString = filterString.concat(addQuery);


//Try Service Portal method
try{
var myListCollector = g_list.get(collectorName);
myListCollector.reset();
myListCollector.setQuery(filterString);
}

//Revert to Service Catalog method
catch(e){
//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 and hide the filter elements (optional)
//Simple method for items with only one list collector
//$('ep').select('.row')[0].hide();
//Advanced method for items with more than one list collector (more prone to upgrade failure)
//var el = $('container_' + g_form.getControl(collectorName).id).select('div.row')[0].hide();

//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);

}
