+ <div class="desc">
+ <h4><b>filter</b><span>Function</span></h4>
+ <p>Custom search function. e.g. function filter(node) {...}</p>
+ <p>filter's parameter: node (node's data -- JSON)</p>
+ <p>filter's return: boolean (true means: match the rules; false means: don't match the rules)</p>
+ <h4 class="topLine"><b>isSingle</b><span>Boolean</span></h4>
+ <p>isSingle = true means: search only one node</p>
+ <p>isSingle = false means: search the array of the nodes</p>
+ <p class="highlight_red">If this parameter is omitted, as same as false</p>
+ <h4 class="topLine"><b>parentNode</b><span>JSON</span></h4>
+ <p>The search range, you can search node from a parent node's child nodes.</p>
+ <p class="highlight_red">If this parameter is omitted, zTree will search node from all nodes.</p>
+ <h4 class="topLine"><b>invokeParam</b><span>anything</span></h4>
+ <p>Custom data object by user, used to calculate in the filter function.</p>
+ <h4 class="topLine"><b>Return </b><span>Array(JSON) / JSON</span></h4>
+ <p>If isSingle = true, will return the first node's data (JSON) what be matched. If no match, return null.</p>
+ <p>If isSingle = false, will return the array of all nodes's data what be matched. if no match, return [ ].</p>

+ <h4>1. Search the nodes which their 'name' contains 'test' and 'level' is 2.</h4>
+ <pre xmlns=""><code>function filter(node) {
+ return (node.level == 2 && node.name.indexOf("test")>-1);
+}
+......
+var treeObj = $.fn.zTree.getZTreeObj("tree");
+var node = treeObj.getNodesByFilter(filter, true); // search only one node
+var nodes = treeObj.getNodesByFilter(filter); // search the array of the nodes
