【问题描述】:
我创建了一个 Ext.TreePanel,我会在节点中有一个图像,在节点的文本中我有图像的 url,但我无法在页面中加载它,我只看到文本,那里可以查看图片吗?
这是我的代码
var root1 = new Tree.AsyncTreeNode({
text: 'Legenda degli starti PAT',
draggable:true, // disable root node dragging
id:'source'
});
var tree1 = new Tree.TreePanel({
renderTo : 'legend',
animate:true,
loader: new Tree.TreeLoader({dataUrl:'legend.php'}),
containerScroll: true,
root: root1,
});
这是 TreePanel 请求的响应
