Meteor Railway Transfer ArrayList value as parameters

'data': function( ){
 var distinctOrgListing = _.uniq(MyCustomCollection.find({}, {sort: {orgName: 1}, fields: {orgName: true}}).fetch().map(function(x) { return x.orgName;}), true);
 console.log("Listing.helpers: distinct listings :" +distinctOrgListing)
 return distinctOrgListing;
}

Listing.helpers: distinct listings: a,b,c< /pre> 
I want
 
>Send the value I received as a parameter to Iron Router so that I can use the value for collection search
 
My router configuration As follows:
 
 
this.route("listingbycompanyL1",{
 path:"/listingL1",
 layoutTemplate: ' ListingbycompanyL1',
 data: function(){
 var update=MyCustomCollection.find({orgName:"XXXX" }).fetch();
 return {
 update:update 
 };
 }
});
How to pass the value I received (a,b,c) to IR and use it to search, where XXXX Is a or b or c

this.route("listingbycompanyL1",{
 // specify the strategy _id as an URL component instead of query parameter
 path:"/listingL1/: a",
 layoutTemplate:'ListingbycompanyL1',
 data: function(){
 var update=MyCustomCollection.find({orgName: this.params.a }).fetch();< br /> return {
 update:update
 };
 }
});

I am a newbie to meteor And have been trying to pass a value from an arraylist to an href pathfor element.

I have a template

The data sent to the template using the helper is basically an array of strings from the following helper

'data': function(){
 var distinctOrgListing = _.uniq(MyCustomCollection.find({}, {sort: {orgName: 1}, fields: {orgName: true}}).fetch().map(function(x) {return x.orgName;}), true);
 console.log("Listing.helpers: distinct listings :" +distinctOrgListing)
 return distinctOrgListing;
}

This will return some data in the form of a list of strings. For example, when printing to the console, I will get

Listing.helpers: distinct listings: a,b,c

I want

>Send the value I received as a parameter to Iron Router so that I can use The value is set to search

My router configuration is as follows:

this.route("listingbycompanyL1",{
 path:"/listingL1 ",
 layoutTemplate:'ListingbycompanyL1',
 data: function(){
 var update=MyCustomCollection.find({orgName:"XXXX" }).fetch();
 return {
 update:update
 };
 }
});

How to pass the value (a,b,c) I received to IR and use it to search, where XXXX is a or b or c

This is a simple parameterized route:

< p>

this.route("l istingbycompanyL1",{
 // specify the strategy _id as an URL component instead of query parameter
 path:"/listingL1/:a",
 layoutTemplate:'ListingbycompanyL1',
 data: function(){
 var update=MyCustomCollection.find({orgName: this.params.a }).fetch();
 return {
 update:update
} ;
 }
});
