所以这就是我想要做的...... 考虑下面的树结构：
var root = {
"name" : "Total1 : " + mynum ,
"size" : 50000,
"children": [{
"name":"Total2" + num1
},
{
"name":"Total3" + num2
},
{
"name":"Total4" + num3
},
{
"name":"Total5" + num4
}
]
};
每一个＆＃34;名称＆＃34;标签，我想要一个任何标签的按钮，当点击弹出打开一个jquery对话框。我无法理解如何这样做，因为这显然不起作用
"name" : "my text" + mynum + "<div id="xyz">Click</div>"
我正在寻找一些东西，通过它我可以识别点击，获取节点id，并进行ajax调用以获取查询并在jquery对话框中显示。 或者可以在右键单击节点时提示选项，以显示查询。
我很感激这些人的任何帮助。谢谢你的推荐
这是我的整个javascript代码：

right: 120,

left: 120

height = 800 - margin.top - margin.bottom;
var root = {
"name" : "Total1 : " + mynum ,
"size" : 50000,
"children": [{
"name":"Total2" + num1
},
{
"name":"Total3" + num2
},
{
"name":"Total4" + num3
},
{
"name":"Total5" + num4
}
]

好吧，我找到了解决方法，我向所有节点输入了右键单击事件oncontextmenu。所以现在当我右键单击时，我会弹出jquery对话框。
