Default is <code>"ctrl"</code>.</p> <p>The special key used to make a drag copy instead of move (<code>"ctrl"</code>, <code>"shift"</code>, <code>"alt"</code>, <code>"meta"</code>).</p> <h3>check_timeout</h3> <p class="meta">A number. Default is <code>200</code>.</p> <p>The number of milliseconds to wait before checking if a move is valid upon hovering a node (while dragging). <code>200</code> is a reasonable value - a higher number means better performance but slow feedback to the user, a lower number means lower performance (possibly) but the user will get feedback faster.</p> <h3>open_timeout</h3> <p class="meta">A number. Default is <code>500</code>.</p> <p>The number of milliseconds to wait before opening a hovered if it has children (while dragging). This means that the user has to stop over the node for half a second in order to trigger the open operation. Keep in mind that a low value in combination with async data could mean a lot of unneeded traffic, so <code>500</code> is quite reasonable.</p> <h3>drop_target</h3> <p class="meta">A string (jQuery selector) (or <code>false</code>). Default is <code>".jstree-drop"</code>.</p> <p>A jquery selector matching all drop targets (you can also use the comma <code>,</code> in the string to specify multiple valid targets). If set to <code>false</code> drop targets are disabled.</p> <h3>drop_check</h3> <p class="meta">A function. Default is <code>function (data) { return true; }</code>.</p> <p>Return <code>false</code> to mark the move as invalid, otherwise return <code>true</code>. The <code>data</code> parameter is as follows:</p> <p style="margin-left:2em;"><code>data.o</code> - the object being dragged</p> <p style="margin-left:2em;"><code>data.r</code> - the drop target</p> <h3>drop_finish</h3> <p class="meta">A function. Default is <code>$.noop</code>.</p> <p>Gets executed after a valid drop, you get one parameter, which is as follows:</p> <p style="margin-left:2em;"><code>data.o</code> - the object being dragged</p> <p style="margin-left:2em;"><code>data.r</code> - the drop target</p> <h3>drag_target</h3> <p class="meta">A string (jQuery selector) (or <code>false</code>). Default is <code>".jstree-draggable"</code>.</p> <p>A jquery selector matching all foreign nodes that can be dropped on the tree (you can also use the comma <code>,</code> in the string to specify multiple valid foreign nodes). If set to <code>false</code> dragging foreign nodes is disabled.</p> <h3>drag_check</h3> <p class="meta">A function. Default is <code>function (data) { return { after : false, before : false, inside : true }; }</code>.</p> <p>Return a boolean for each position. The <code>data</code> parameter is as follows:</p> <p style="margin-left:2em;"><code>data.o</code> - the foreign object being dragged</p> <p style="margin-left:2em;"><code>data.r</code> - the hovered node</p> <h3>drag_finish</h3> <p class="meta">A function. Default is <code>$.noop</code>.</p> <p>Gets executed after a dropping a foreign element on a tree item, you get one parameter, which is as follows:</p> <p style="margin-left:2em;"><code>data.o</code> - the foreign object being dragged</p> <p style="margin-left:2em;"><code>data.r</code> - the target node</p> </div> <h2 id="demos">Demos</h2> <div class="panel"> <h3>Using the dnd plugin</h3> <p>Drag stuff around!</p> <div class="jstree-drop" style="clear:both; border:5px solid green; background:lime; color:green; height:40px; line-height:40px; text-align:center; font-size:20px;">I have the jstree-drop class</div> <div class="jstree-draggable" style="margin:10px 0; clear:both; border:5px solid navy; background:aqua; color:navy; height:40px; line-height:40px; text-align:center; font-size:20px;">I have the jstree-draggable class</div> <div id="demo1" class="demo"> <ul> <li id="phtml_1"> <a href="#">Root node 1</a> <ul> <li id="phtml_2"> <a href="#">Child node 1</a> </li> <li id="phtml_3"> <a href="#">Child node 2</a> </li> </ul> </li> <li id="phtml_4"> <a href="#">Root node 2</a> </li> </ul> </div> <script type="text/javascript" class="source"> $(function () { $("#demo1").jstree({ "dnd" : { "drop_finish" : function () { alert("DROP"); }, "drag_check" : function (data) { if(data.r.attr("id") == "phtml_1") { return false; } return { after : false, before : false, inside : true }; }, "drag_finish" : function (data) { alert("DRAG OK"); } }, "plugins" : [ "themes", "html_data", "dnd" ] }); }); </script> <h3>Reorder only demo</h3> <div id="demo2" class="demo"> <ul> <li id="rhtml_1"> <a href="#">Root node 1</a> <ul> <li id="rhtml_2"> <a href="#">Child node 1</a> </li> <li id="rhtml_3"> <a href="#">Child node 2</a> </li> <li id="rhtml_4"> <a href="#">Child node 3</a> </li> <li id="rhtml_5"> <a href="#">Child node 4</a> </li> </ul> </li> <li id="rhtml_6"> <a href="#">Root node 2</a> </li> <li id="rhtml_7"> <a href="#">Root node 3</a> </li> </ul> </div> <script type="text/javascript" class="source"> $(function () { $("#demo2").jstree({ "crrm" : { "move" : { "check_move" : function (m) { var p = this._get_parent(m.o); if(!p) return false; p = p == -1 ? this.get_container() : p; if(p === m.np) return true; if(p[0] && m.np[0] && p[0] === m.np[0]) return true; return false; } } }, "dnd" : { "drop_target" : false, "drag_target" : false }, "plugins" : [ "themes", "html_data", "crrm", "dnd" ] }); }); </script> </div> <h2 id="api">API</h2> <div class="panel api"> <div style="height:1px; visibility:hidden;"> <span id="dnd_show"> </span> <span id="dnd_open"> </span> <span id="dnd_finish"> </span> <span id="dnd_enter"> </span> <span id="start_drag"> </span> </div> <h3 id="dnd_prepare">.dnd_prepare ( ), .dnd_show ( ), .dnd_open ( ), .dnd_finish ( ), .dnd_enter ( ), .dnd_leave ( ), .start_drag ( )</h3> <p>All those functions are used internally only.
