关于Metadata Client Object Model 的一些操作

一、查询指定的Termset及子项

<script type="text/javascript" src="/Style%20Library/aaaa/Scripts/jquery-1.11.1.min.js" language="javascript"></script>

    <script type="text/javascript">RegisterSod("sp.taxonomy.js", "\u002f_layouts\u002f15\u002fsp.taxonomy.js?rev=l0dFB37050OQxbmrgu6z7Q\u00253D\u00253D");</script>

    <script type="text/javascript">

        $(document).ready(function () {

            var scriptbase = _spPageContextInfo.webServerRelativeUrl + "_layouts/15/";

            $.getScript(scriptbase + "SP.Runtime.js",

                function () {

                    $.getScript(scriptbase + "SP.js", function () {

                        $.getScript(scriptbase + "SP.Taxonomy.js", execOperation);

                    });

                }

            );

        });

        function execOperation() {

            //Current Context

            var context = SP.ClientContext.get_current();

            //Current Taxonomy Session

            var taxSession = SP.Taxonomy.TaxonomySession.getTaxonomySession(context);

            //Term Stores

            var termStores = taxSession.get_termStores();

            //Name of the Term Store from which to get the Terms.

            var termStore = termStores.getByName("IdeaTracker_MMS");

            //GUID of Term Set from which to get the Terms.

            var termSet = termStore.getTermSet("bcf031d3-7eb2-433a-b5ff-b92398758431");

            var terms = termSet.getAllTerms();

            context.load(terms);

            context.executeQueryAsync(function () {

                var termEnumerator = terms.getEnumerator();

                var termList = "Terms: \n";

                while (termEnumerator.moveNext()) {

                    var currentTerm = termEnumerator.get_current();

                    termList += currentTerm.get_name() + "\n";

                }

                alert(termList);

            }, function (sender, args) {

                console.log(args.get_message());

            });

        }

    </script>

二、创建Term Group

<script type="text/javascript">

        $(document).ready(function () {

            var scriptbase = _spPageContextInfo.webServerRelativeUrl + "_layouts/15/";

            $.getScript(scriptbase + "SP.Runtime.js",

                function () {

                    $.getScript(scriptbase + "SP.js", function () {

                        $.getScript(scriptbase + "SP.Taxonomy.js", execOperation);

                    });

                }

            );

        });

        function execOperation() {

            //Current Context

            var context = SP.ClientContext.get_current();

            //Current Taxonomy Session

            var taxSession = SP.Taxonomy.TaxonomySession.getTaxonomySession(context);

            //Term Stores

            var termStores = taxSession.get_termStores();

            //Term Store under which to create the group.

            var termStore = termStores.getByName("Taxonomy_Dmxzz8tIBzk8wNVKQpJ+xA==");

            //New Group with name and new GUID

            var newGroup = termStore.createGroup("New Group Name", "b300304a-1693-4629-a1c0-dff7bda644ff");

            context.load(newGroup);

            context.executeQueryAsync(function () {

                console.log(newGroup.get_name());

            }, function (sender, args) {

                console.log(args.get_message());

            });

        }

    </script>

三、创建Term Set

<script type="text/javascript">

        $(document).ready(function () {

            var scriptbase = _spPageContextInfo.webServerRelativeUrl + "_layouts/15/";

            $.getScript(scriptbase + "SP.Runtime.js",

                function () {

                    $.getScript(scriptbase + "SP.js", function () {

                        $.getScript(scriptbase + "SP.Taxonomy.js", execOperation);

                    });

                }

            );

        });

        function execOperation() {

            //Current Context

            var context = SP.ClientContext.get_current();

            //Current Taxonomy Session

            var taxSession = SP.Taxonomy.TaxonomySession.getTaxonomySession(context);

            //Term Stores

            var termStores = taxSession.get_termStores();

            //Term Store under which to create the Term Set.

            var termStore = termStores.getByName("Taxonomy_Dmxzz8tIBzk8wNVKQpJ+xA==");

            //Get group by GUID

            var peopleGroup = termStore.getGroup("97eaa7b8-9778-4f61-acb3-7f47abba13c3");

            //Create New Term Set in Group with Name, New GUID and LCID

            var newTermSet = peopleGroup.createTermSet("New TermSet Name", "49dac247-d315-4065-8718-e8c3f50e7dcd", 1033);

            context.load(newTermSet);

            context.executeQueryAsync(function () {

                console.log(newTermSet.get_name());

            }, function (sender, args) {

                console.log(args.get_message());

            });

        }

    </script>

四、创建Term

<script type="text/javascript">

        function execOperation() {

            //Current Context

            var context = SP.ClientContext.get_current();

            //Current Taxonomy Session

            var taxSession = SP.Taxonomy.TaxonomySession.getTaxonomySession(context);

            //Term Stores

            var termStores = taxSession.get_termStores();

            //Term Store under which to create the term.

            var termStore = termStores.getByName("Taxonomy_Dmxzz8tIBzk8wNVKQpJ+xA==");

            //Term Set under which to create the term.

            var termSet = termStore.getTermSet("b49f64b3-4722-4336-9a5c-56c326b344d4");

            //Name of the term, LCID and a new GUID for the term.

            var newTerm = termSet.createTerm("India", 1033, "b49f64b3-4722-4336-9a5c-56c326b344a9");

            //newTerm.set_isAvailableForTagging(true);

            context.load(newTerm);

            context.executeQueryAsync(function () {

                alert("Term Created: " + newTerm.get_name());

            }, function (sender, args) {

                console.log(args.get_message());

            });

        }

    </script>

五、获取单一值的字段

<script type="text/javascript">

        function execOperation() {

            var context = SP.ClientContext.get_current();

            var list = context.get_web().get_lists().getByTitle('TaxonomyCustomList');

            var listItem = list.getItemById(1);

            context.load(listItem);

            context.executeQueryAsync(function () {

                //Single Value Taxonomy Column

                var label = listItem.get_item("MyTaxColumn").get_label();

                //Term GUID

                var termGUID = listItem.get_item("MyTaxColumn").get_termGuid();

                //Type ID

                var typeID = listItem.get_item("MyTaxColumn").get_typeId();

                //WSS ID

                var wssID = listItem.get_item("MyTaxColumn").get_wssId();

            }, function (sender, args) {

                console.log(args.get_message());

            });

        }

    </script>

六、获取多选值的字段

<script type="text/javascript">

        function execOperation() {

            var context = SP.ClientContext.get_current();

            var list = context.get_web().get_lists().getByTitle('TaxonomyCustomList');

            var listItem = list.getItemById(1);

            context.load(listItem);

            context.executeQueryAsync(function () {

                //Multivalue Taxonomy Column

                var taxEnumerator = listItem.get_item("MyTaxColumn").getEnumerator();

                while (taxEnumerator.moveNext()) {

                    //Label

                    var currentTerm = taxEnumerator.get_current();

                    //Label

                    var label = currentTerm.get_label();

                    //Term GUID

                    var termGUID = currentTerm.get_termGuid();

                    //Type ID

                    var typeID = currentTerm.get_typeId();

                    //WSS ID

                    var wssID = currentTerm.get_wssId();

                }

            }, function (sender, args) {

                console.log(args.get_message());

            });

        }

    </script>
