EXT TREE CHECK
var Tree = Ext.tree; var tree = new Tree.TreePanel({ el:'tree-div', useArrows:true, autoScroll:true, animate:true, enableDD:true, containerScroll: true, loader: new Tree.TreeLoader({ dataUrl:'treecheckjson.jsp' }) }); tree.on('checkchange', function(node, checked) { node.expand(); node.attributes.checked = checked; node.eachChild(function(child) { child.ui.toggleCheck(checked); child.attributes.checked = checked; child.fireEvent('checkchange', child, checked); }); }, tree); var root = new Tree.AsyncTreeNode({ text: 'Ext JS', draggable:false, checked:false, id:'0' }); tree.setRootNode(root); tree.render(); root.expand(); //带复选框(checkbox)的树 //改编自ExtJs 自带的tree例子，选中父节点后，所有子节点会自动选上。 //该例子点击父节点如果速度过快，有时候不会自动选中子节点！ var checkedNodes = tree.getChecked();//tree必须事先创建好. var s = []; for(var i=0;i<checkedNodes.length;i++){ s.push(checkedNodes.id) } //得到里面选中的node id 值数组
