Please find the below code read lists same way add the items function displayLists() { // Get the available SharePoint lists and then set them into // the context. lists = web.get_lists(); context.load(lists); context.executeQueryAsync(onGetListsSuccess onGetListsFail); } function onGetListsSuccess(sender args) { // Success getting the lists. Set references to the list // elements and the list of available lists. var listEnumerator = lists.getEnumerator(); var selectListBox = document.getElementById(selectlistbox); if (selectListBox.hasChildNodes()) { while (selectListBox.childNodes.length >= 1) { selectListBox.removeChild(selectListBox.firstChild); } } // Traverse the elements of the collection and load the name of // each list into the dropdown list box. while (listEnumerator.moveNext()) { var selectOption = document.createElement(option); selectOption.value = listEnumerator.get_current().get_title(); selectOption.innerHTML = listEnumerator.get_current().get_title(); selectListBox.appendChild(selectOption); } }
