According to the selectNode() documentation range.selectNode() expects a param of type node where your node is a string -> var res = 'http://example.com?from=' + name;.

The Range.selectNode() method sets the Range to contain the Node and its contents. The parent Node of the start and end of the Range will be the same as the parent of the referenceNode.

Just create a dummy element for copy, append it to your DOM, copy it and remove it from DOM:

$scope.copyToClipboard = function (name) {
    var copyElement = document.createElement("textarea");
    copyElement.style.position = 'fixed';
    copyElement.style.opacity = '0';
    copyElement.textContent = 'http://example.com?from=' + decodeURI(name);
    var body = document.getElementsByTagName('body')[0];
    body.appendChild(copyElement);
    copyElement.select();
    document.execCommand('copy');
    body.removeChild(copyElement);
}

<button class="btn btn-info" 
        ng-click="copyToClipboard(data.name);">copy</button>
