How to fetch query parameters in a template?

I am using Meteor 1.2.1 + iron-router with autopublish turned on

I would like to construct an anchor href based on collection values returned by a helper and query params

Is it possible to do this in the template tag, e.g. query_param1 should be read from the URL?

<template name="dataEntry">
  {{#each data}}
    <li>
      <a href="/listing?name={{name}}&color=<query_param1>">
       Data name
      </a>
    </li>
  {{/each}}
</template>

Above, {{name}} is returned by the collection and query parameters are appended to that to create a full hyperlink for the href.

You can use @Stephen's suggestion like this.

In your template html,

     <template name="dataEntry">
        {{#each data}}
            <li>
                <a href="/listing?{{queryParams}}">
                    Data name
                </a>
            </li>
        {{/each}}
    </template>

In your template JS,

Template.dataEntry.helpers({
   "queryParams": function () {
       var name = "";
       //get name from collection here like...
       //name = Meteor.user().profile.firstName;
       var color = Router.current().params.color;
       return "name=" + name + "&color=" + color;
    }
});

Or you can use two separate helpers

In your template html,

     <template name="dataEntry">
        {{#each data}}
            <li>
                <a href="/listing?name={{name}}&color={{color}}">
                    Data name
                </a>
            </li>
        {{/each}}
    </template>

In your template JS,

Template.dataEntry.helpers({
   "name": function () {
       var name = "";
       //get name from collection here like...
       //name = Meteor.user().profile.firstName;
       return name;
    },
   "color": function () {
       return Router.current().params.color;
    }
});

You can access an IronRouter param through a helper, e.g.:

Router.current().params.query_param1
