Simple script to add link to link resolver in Summon results

all_full_text.js

setTimeout(() => {
    libScope(angular.element('html').scope());
  }, 1000);

function libScope(scope) {
      // Watch results feed for changes...
    scope.$watchCollection('feed', () => {
        // give AngularJS time to update the DOM
        // Probably need to wait a few seconds before running this to make sure the DOM loads
        setTimeout(function() {
            // Get all the results
            const results = document.querySelectorAll('#results > div.inner > ul > li')
            const linkResolver = 'https://ey7mr5fu9x.search.serialssolutions.com'
            const linkLabel = 'All Full Text Options'

            // Get OpenURL and add link to result
            for (const result of results) {

                // Get the OpenURL in a variable
                var OpenURLSpan = result.querySelector('span.Z3988');
                if (OpenURLSpan && !result.querySelector('.fulltext-hack')) {
                    var OpenURL = OpenURLSpan.title
                    // add a new link to the right of the Full Text Online link
                    jQuery(OpenURLSpan).after(`<div class="fulltext-hack availability" style="margin-left:1.1em;"><a tabindex="0" target="_blank" class="availabilityLink" href="${linkResolver}/?${OpenURL}&newui=1clickoff">${linkLabel}</a></div>`)
                }
            }
        }, 500) // Wait a second and a half before running this on page load
    })
}

Just testing if a record has an OpenURL isn't good enough—you'll end up with links for all your catalog records, too. So you probably want to check the record's type before adding the fulltext-hack link. Rather than use the DOM for this and the OpenURL, you can get a record's data via angular with angular.element('.documentSummary').scope().document (results list is structured li > div.documentSummary)
