EXT树重新加载

ext js 创建树

var Tree = Ext.tree;

  deptTree = new Tree.TreePanel({
      el : elementId,
      autoScroll:true,
      animate:true,
      enableDD:true,
      containerScroll: true,
      loader: new Tree.TreeLoader({
          dataUrl: CONTEXT_PATH + "/depts/deptTree.do",
          baseParams: filter
      })
  });

  // set the root node
  root = new Tree.AsyncTreeNode({
      text: rootDesc,
      draggable:false,
      id:'-1'
  });
  deptTree.setRootNode(root);

  // render the deptTree
  deptTree.render();
  root.expand();

 		var Tree = Ext.tree;
deptTree = new Tree.TreePanel({
el : elementId,
autoScroll:true,
animate:true,
enableDD:true,
containerScroll: true,
loader: new Tree.TreeLoader({
dataUrl: CONTEXT_PATH + "/depts/deptTree.do",
baseParams: filter
})
});
// set the root node
root = new Tree.AsyncTreeNode({
text: rootDesc,
draggable:false,
id:'-1'
});
deptTree.setRootNode(root);
// render the deptTree
deptTree.render();
root.expand();

ext js 重新加载树

  /**
 * 重新加载树
 *
 * @param {f}
 *          f 过滤树的条件 如:{placeid:'xxxxx'}
 */
reload : function (f){
    filter = f;

    var loader = deptTree.getLoader();
    deptTree.on('beforeload', function(){
            loader.dataUrl = loader.dataUrl ;
            loader.baseParams = filter;
    });
    root.reload();
}
