Hiding Group Headers from SharePoint List View

We can hide the Group name in out of the box list view using JavaScript.

Grouped List View before adding JavaScript:

JavaScript (MOSS 2007/WSS 3.0):

<script type="text/javascript" language="javascript">

        _spBodyOnLoadFunctionNames.push("HideHeaders");

        function HideHeaders() {

            var elements = getElementsByClassName(document, "td", "ms-gb");

            var elem;

            for (var i = 0; i < elements.length; i++) {

                elem = elements[i];

                elem.childNodes[3].style.display = "none";

                elem.childNodes[4].nodeValue = elem.childNodes[4].nodeValue.replace(':', '');

            }

            elements = getElementsByClassName(document, "td", "ms-gb2");

            for (var i = 0; i < elements.length; i++) {

                elem = elements[i];

                elem.childNodes[3].style.display = "none";

                elem.childNodes[4].nodeValue = elem.childNodes[4].nodeValue.replace(':', '');

            }

        }

        function getElementsByClassName(oElm, strTagName, strClassName) {

            var arrElements = (strTagName == "*" && oElm.all) ? oElm.all : oElm.getElementsByTagName(strTagName);

            var arrReturnElements = new Array();

            strClassName = strClassName.replace(/\-/g, "\\-");

            var oRegExp = new RegExp("(^|\\s)" + strClassName + "(\\s|$)");

            var oElement;

            for (var i = 0; i < arrElements.length; i++) {

                oElement = arrElements[i];

                if (oRegExp.test(oElement.className)) {

                    arrReturnElements.push(oElement);

                }

            }

            return (arrReturnElements)

        }

    </script>

JavaScript (SharePoint 2010/SharePoint Foundation 2010):

<script type="text/javascript" language="javascript">

        _spBodyOnLoadFunctionNames.push("HideHeaders");

        function HideHeaders() {

            var elements = getElementsByClassName(document, "td", "ms-gb");

            var elem;

            for (var i = 0; i < elements.length; i++) {

                elem = elements[i];

                elem.childNodes[0].childNodes[1].nodeValue = "";

                elem.childNodes[1].nodeValue = elem.childNodes[1].nodeValue.replace(':', '');

            }

            elements = getElementsByClassName(document, "td", "ms-gb2");

            for (var i = 0; i < elements.length; i++) {

                elem = elements[i];

                elem.childNodes[1].childNodes[1].nodeValue = "";                elem.childNodes[2].nodeValue = elem.childNodes[2].nodeValue.replace(':', '');

            }

        }

        function getElementsByClassName(oElm, strTagName, strClassName) {

            var arrElements = (strTagName == "*" && oElm.all) ? oElm.all : oElm.getElementsByTagName(strTagName);

            var arrReturnElements = new Array();

            strClassName = strClassName.replace(/\-/g, "\\-");

            var oRegExp = new RegExp("(^|\\s)" + strClassName + "(\\s|$)");

            var oElement;

            for (var i = 0; i < arrElements.length; i++) {

                oElement = arrElements[i];

                if (oRegExp.test(oElement.className)) {

                    arrReturnElements.push(oElement);

                }

            }

            return (arrReturnElements)

        }

    </script>
