我正在使用jstree但是当我尝试获取有关节点的任何信息时,例如文本,位置(例如单击节点或执行拖放),我得到javascript错误data.rslt undefined。
这是我的代码:
<body>
<div id="alog"></div>
<div id="demo">
<ul>
<li><a>Team A's Projects</a>
<ul>
<li><a>Iteration 1</a>
<ul>
<li><a>Story A</a></li>
<li><a>Story B</a></li>
<li><a>Story C</a></li>
</ul>
</li>
<li><a>Iteration 2</a>
<ul>
<li><a>Story D</a></li>
</ul>
</li>
</ul>
</li>
</ul>
</div>
</body>
<script>
$(function () {
$("#demo").bind("before.jstree", function (e, data) {
$("#alog").append(data.func + "<br />");
})
$("#demo").bind("select_node.jstree", function (e, data) {
//alert($(data["node"]).find("a:first").text());
})
.bind("create.jstree", function (e, data) {
$.post(
"/static/v.1.0pre/_demo/server.php",

"operation" : "create_node",
"id" : data.rslt.parent.attr("id").replace("node_",""),
"position" : data.rslt.position,
"title" : data.rslt.name,
"type" : data.rslt.obj.attr("rel")
},
function (r) {
if(r.status) {
$(data.rslt.obj).attr("id", "node_" + r.id);
}
else {
$.jstree.rollback(data.rlbk);
}
}
);
})
.bind("remove.jstree", function (e, data) {
data.rslt.obj.each(function () {
$.ajax({
async : false,

});
})
