Service Catalog stuff
loop round variables with similar names to get values:
current.variables.<variable_name> works fine when you know the variable name
but what if you have a number of repeat variables with very similar names on the catalog item form, such as
retail_kit_1
retail_kit_2
retail_kit_3
...
And you wish to loop round and get all the values, and then use them to carry out a repeat task (for example, insert new CIs into the CMDB)?
must be an easier way of doing this...but until I find it here's some code that does the trick:
repeat fields on the catalog item form:
code to loop round these, for example in the RITM workflow:
//--get a load of variable values which are named very similar
var grRITM=new GlideRecord('sc_req_item');
if (grRITM.get('number', 'RITM0016189')){
getVariables (grRITM);
}
function getVariables (grRITM){
var variablePrefix='retail_kit_';
for (i=1;i<10;i++){
var kit_extra= get_variable(variablePrefix+i, grRITM);
if (!gs.nil(kit_extra)){
gs.print(kit_extra);
//--do what ya gotta do...
//....
}
}
}
function get_variable (variable_name, grRITM){
//--retrieve a variable value where the variable name is passed in as a string
var sReturn='';
var varGR=new GlideRecord('sc_item_option_mtom');
varGR.addQuery('request_item', grRITM.sys_id); //--sys id of the sc_req_item
varGR.addQuery('sc_item_option.item_option_new.name='+variable_name);
varGR.query();
if(varGR.next()){
var gr= new GlideRecord ('sc_item_option');
gr.addQuery('sys_id', varGR.sc_item_option.toString());
gr.query();
if(gr.next()){
sReturn=gr.value; //--sys id, typically for this search
}
}
return sReturn;
}
Service Catalog: retrieve the catalog item sysid in a **server side** script:
Scenario: I need to obtain the catalog item sys id in the client callable script include, used to build up a reference qualifier for a catalog variable
requirement: this must be Service Portal AND classic ServiceNow compatible!
Solution:
1) create a hidden string variable in which to store the sys id on the catalog item, and create a UI policy to hide the variable everywhere (under advanced on the UI policy, tick boxes next to cat item, request item, tasks)
2) populate the hidden variable in form load catalog client script:
//--set hidden field--store sys id for ref qualifiers (referenced in script include MAB_refqual_functions)
//--Cat item id:
var itemID='';
try{
//--standard servicenow form
itemID= gel('sysparm_id').value;
}catch (ex){
//--service portal friendly, need the catch ex to continue to here in SP
itemID= g_form.getSysId();
}
g_form.setValue('hidden_catitem_sysid',itemID );
3) Et Voila! in the client callable script include, you can access the variable like so:
var cat_item=current.variables.hidden_catitem_sysid;
if (cat_item=='4c08fea3379d97803bef532e53990e03'){
//--must be additional equipment item:
sQuery=sQuery+'^u_order_type!=replacement';
}else{
//--must be lost or stolen item:
sQuery=sQuery+'^u_order_type!=additional';
}
