Dynatree花费在装载

我创造与节点选项dynatree扩大=假。但是当我查看这棵树时，它显示了所有在开始时的花费。如何在初始阶段让树全崩溃。下面是我的代码Dynatree花费在装载

$(function(){ 
      // Attach the dynatree widget to an existing <div id="tree"> element 
      // and pass the tree options as an argument to the dynatree() function: 
      $("#tree").dynatree({ 
       onActivate: function(node) { 
        // A DynaTreeNode object is passed to the activation handler 
        // Note: we also get this event, if persistence is on, and the page is reloaded. 
        //alert("You activated " + node.data.key); 
       }, 
       persist: false, 
       checkbox: true, 
       generateIds: false, 

       classNames: { 
        checkbox: "dynatree-checkbox", 
        expanded: "dynatree-expanded" 
       }, 
       selectMode: 3, 
       children: {!JsonString}, 
       onSelect: function(select, node) { 
        // Get a list of all selected nodes, and convert to a key array: 
        var selKeys = $.map(node.tree.getSelectedNodes(), function(node){ 
         return node.data.key; 
        }); 
        jQuery(document.getElementById("{!$Component.selectedKeys}")).val(selKeys.join(", ")); 

        // Get a list of all selected TOP nodes 
        var selRootNodes = node.tree.getSelectedNodes(true); 
        // ... and convert to a key array: 
        var selRootKeys = $.map(selRootNodes, function(node){ 
         return node.data.key; 
        }); 
       }, 

      }); 

     });

你能成为一个更清楚一点上你题？请阅读[faq]（http://stackoverflow.com/faq） – Freakyuser 2013-02-27 11:45:55

在我dynatree我使用AJAX的init和扩大整个树，但也许我的代码这种修改将帮助您：

onPostInit: function(isReloading, isError) { 
    this.$tree.dynatree('getRoot').visit(function(node){ 
     node.expand(false); 
    }); 
}
