jQuery获取项目父级

(父对象的内容)

例如,在下面的示例中,“第1.1项”的父项将是“第2项”。

项目:

        <ul class="sortable" id="page-list">

            <li><div>Item 1</div></li>
            <li><div>Item 2</div>
                <ul>
                    <li><div>Sub Item 1.1</div></li>
                    <li><div>Sub Item 1.2</div></li>
                    <li><div>Sub Item 1.3</div></li>
                    <li><div>Sub Item 1.4</div></li>
                </ul>
            </li>

        </ul>

            function saveNewList() {
            //get DIV contents in order
            var divContents = [];
            $("ul.sortable > li div").each(function() { divContents.push($(this).text()) });
            var quotedCSV = '"' + divContents.join('", "') + '"';
            $("#results").text(quotedCSV);
            //get DIV parents' contents in order
            var divParents = [];
            // something needs to go here...
            var quotedCSVparents = '"' + divParents.join('", "') + '"';
            $("#results2").text(quotedCSVparents);


        }
